Vacuum Windshield Wiper Assembly

See Fig. 1

The windshield wiper assembly consists of a motor, auxiliary drive and two transmissions. The standard motor is vacuum operated and the optional motor is electrically powered. Both motors are interchangeable. The transmission incorporates spring loaded pulleys which provide for adjustment of the wiper cable tension. The wiper motor auxiliary drive incorporates two drums to which transmission drive cables are attached. The wiper motor and auxiliary drive assembly is installed to engine side of the dash panel. The motor and auxiliary assembly may be removed as a unit or the motor may be removed separately.

Transmission Cable

Adjustment

The windshield wiper transmission drive cables are tensioned by spring loaded pulleys. The end of the transmission shaft is pushed in to unlock the pulleys. To tension cables push in on transmission shaft end if blade has been removed or on the base of the wiper arm if the, blade is installed.

To release cable tension for removal of components push in on transmission shaft end and have helper on the inside, pull on cables to obtain desired slack then release pressure on transmission shaft.

NOTE: Wiper blade snap or over-travel is indicative of loose transmission drive cables.

Electric Windshield Wiper Assembly

The electric windshield wiper (Fig. 3) used on the 1957 Chevrolet is a 12-volt DC unit powered by an internally grounded motor containing both a series and shunt field. The armature of the motor is fitted with a worm shaft which drives the oscillating mechanism through a nylon gear.

A leaf contact-type switch enclosed within the motor housing controls the motor and has three positions; high speed, low speed, and a park, or off position. This switch is controlled by means of a nylon slider mounted externally over the switch on the motor housing which in turn is operated by a bowden cable from the dash panel.

To protect the motor from damage due to overheating, a thermal circuit breaker is built into the case at the commutator end of the motor.

Basically, the electric windshield wiper consists of the cast motor housing, electric motor, the switch mechanism, and the oscillating drive mechanism. A stamped steel case mounts the thermal circuit breaker and motor brushes and completes the encasement of the motor. Individual stamped covers are used over both the switch and oscillating drive recesses in the motor housing. The auxiliary drive mounting bracket which attaches the wiper unit to the dash panel is permanently fastened to the oscillating section cover. An oscillating drive arm is pressed onto the oscillating shaft in a fixed position and should not be removed in service.

Stopping the Wiper

With the unit operating, moving the wiper control on the instrument panel to the off, or park, position moves the nylon slider on the switch cover which moves the latch assembly switch arm (fig. 4) in the switch housing. The latch assembly switch arm is attached to the shaft of the latch assembly toggle (fig. 5), therefore switch arm movement results in like action by the latch toggle. As the spring-loaded latch assembly toggle snaps away from the oscillating drive mechanism, the latch assembly arm (fig. 5) reacts in the opposite direction, thus placing the arm in the path of the clockwise rotating drive assembly disc (fig. 5). After the latch arm contacts the ear of the drive assembly disc as shown in figure 6, the rest of the drive assembly continues to turn, tightening a spring attached to both the nylon gear (fig. 5) and the drive assembly disc. This build-up of spring tension forces the drive pin (fig. 7) to move toward the outer radius of the yoke in the drive assembly, thus increasing the arc-of-travel of the connecting rod (fig. 5). By this means, the additional angular travel required to bring the wiper blades to rest against the cowl molding is provided.

Attached to the opposite end of the oscillating shaft in the switch portion of the motor housing is the breaker arm (fig. 4). During operation of the wiper, the breaker arm oscillates freely inside the switch casting. However, once the drive pin arc-of-travel is increased as described above and as illustrated in figure 7, the oscillation range of the breaker arm (fig. 4) is altered causing the arm to hit the fiber cam and trip the contacts. This action trips contact No. 4 (fig. 4), moving it away from contact No. 3 which breaks the ground and moves No. 4 into contact No. 5 which results in a momentary short being thrown across the armature. This operation provides a dual purpose: First, the separating of contacts No. 3 and 4 breaks the circuit to the motor and finally, the closing of contacts No. 4 and 5 shorts the armature thus providing considerable braking action to overcome any coasting action of the motor when shut down. Figure 8 provides an electrical diagram of the unit with the switch contacts in their park relationship.

Starting the Wiper

Moving the switch slider (fig. 3) by means of the control located on the dash into slow speed, or the first operating position, trips the latch assembly toggle (fig. 5), knocking the latch assembly arm clear of the ear of drive assembly disc.

This releases the spring tension built up as the unit went into park, snapping the drive pin back to its original position in the yoke as shown in figure 6. By this means, the usual wiper pattern of the blade arms is re-established.

At the same time that the latch assembly toggle releases the spring tension in the drive and oscillating portion, the movement of the switch slider causes contact Nos. 1 and 2 to close and Nos. 3 and 4 to close, thus forming the wiper low speed circuit 9 .

Low Speed Circuit

In low speed and following the diagram shown in Fig. 9, contact Nos. 1 and 2 are closed and Nos. 3 and 4 are closed. From source, the current passes the circuit breaker and energizes the series field. After passing through the series field, the power is divided; part is directed to the armature and the remainder is eliminated by being diverted to ground through the shunt field, through contacts No. 1 and 2, then to contact No. 4, and finally to contact No. 3 which is grounded. In following this path, it is well to remember that current always follows the path of least resistance, therefore in low speed, no current passes through the resistor because of the more direct path to ground.

The major point to remember concerning low speed operation is that only about one-half of the power is used to drive the motor; the remainder is diverted to ground.

High Speed Circuit

Moving the wiper control on the dash panel further closes the high speed circuit (fig. 10A). For high speed operation, all contacts are open with the exception of Nos. 3 and 4 which produces the following electric flow: From the source, current flows through the circuit breaker and energizes the series field as in low speed operation. Upon leaving the series field, the current once again divides; half going directly to the armature and the remainder through the shunt field. However, with only contacts No. 3 and 4 closed, the current is forced to flow through the resistor to reach ground via the jumper to No. 4 and finally to No. 3 contact and ground. By forcing the current through the resistor, the flow through the shunt field is slowed considerably, consequently more current is forced to flow through the armature to reach ground and the motor speed is increased proportionately.

CARE, MAINTENANCE AND ADJUSTMENT

Three adjustments are required for proper functioning of the electric windshield wiper; armature and end-play adjustment, drive assembly end-play adjustment, and switch adjustment. Of these, both end-play adjustments would usually be performed either during or after complete overhaul of the unit. Drive assembly end-play is accomplished during rebuild of the unit whereas the armature end-play adjustment is made after reinstalling the wiper on the car. Loss of or incorrect switch adjustment accounts for the majority of wiper complaints, therefore it is with this adjustment that the serviceman should be most critical.

It is possible that adjustments within the switch compartment could be made with the wiper installed on car, however, due to the general inaccessibility of the wiper and its ease of removal, it is recommended that the unit be removed so that all service procedures may be made on the bench.

Switch

Adjustment

  1. Remove the switch housing cover.
  2. Move the latch assembly switch arm ( fig. 4) against the fiber cam until the switch contacts snap to the low speed position (fig.9). Further lateral movement of the latch switch arm should separate contacts Nos. 1 and 2 and hold contacts Nos. 3 and 4 closed, thus forming the high speed circuit (fig. 10).
  3. If latch assembly switch arm travel is insufficient to move the fiber cam adequately to move the contacts into their low and high speed positions, loosen the two switch mounting screws (fig. 4) and shift the switch assembly as required.
  4. When the unit is stopped, the breaker arm (fig. 4) should contact the fiber cam and move it sufficiently to snap the switch contacts into their park position (fig. 8). If the motor does not stop when the dash control is turned to the "OFF" position, the switch assembly mounting screws (fig. 4) should be again loosened and the switch shifted toward the breaker arm.

NOTE: Although seldom necessary, the breaker arm (fig. 4) may be bent toward the fiber cam if the unit cannot be stopped after shifting the switch its full limit. When the breaker arm is stopped at its park position, the minimum clearance between the arm and cam guide should be 1/32" (fig. 11).

Armature End-Play

Adjustment

  1. This adjustment is generally required only after a rebuild of the wiper but can be made at any time with the unit installed.
  2. Connect a DC ammeter in the circuit, start the electric wiper, and note the ampere draw.
  3. Tighten the armature end - play adjusting screw located in the end of the cast motor housing until a rise in the current draw is noted, then back-off adjusting screw slowly until ampere draw returns to that in (1) above. As a safety factor, back off screw an additional 1/8 turn.
  4. To lock adjustment, tighten jam nut.
Drive Assembly End-Play

Adjustment

Drive assembly end-play should be established within .005"-.008" during assembly through use of end-play washers beneath the snap ring on the portion of drive assembly shaft shown at the bottom center of figure 4.

MAJOR SERVICE OPERATIONS

As mentioned earlier, complete tear-down of the wiper assembly is seldom required as the majority of its malfunctions occur within the external controls to the wiper or within the switch housing.

The overhaul procedures are broken down into three major areas: switch assembly, oscillating and drive assembly, and motor. Both the switch and motor assemblies can be serviced without disturbing other sections of the wiper but to disassemble and assemble to the oscillating and drive portion it is also necessary to remove certain elements from the switch housing. Because of the general independence of each section of the wiper, complete disassembly, inspection, and assembly instructions are provided under the wiper component headings.

Switch

Disassembly

  1. Remove four screws securing switch cover and remove cover.
  2. Remove two switch assembly mounting screws (fig. 4) and lift out switch to extent of slack in connecting wires.
  3. Complete removal of switch assembly by placing a hot soldering iron against the three lead connections to the switch. Code the connection points to insure that the color coded wires are connected at the proper locations at assembly.
  4. Remove the switch breaker arm (fig. 4) from end of oscillating shaft by removing plastic retainer.

CAUTION: Do not remove latch assembly switch arm (fig. 4).

Cleaning and Inspection

Check all switch contacts for foreign matter or possible deformation. Contacts can be cleaned with a cloth dampened with carbon tetrachloride or small imperfections removed with emery paper. Broken contacts require replacement of the switch as an assembly.

Be especially careful to check that there is no foreign matter bridging the insulators at the base of the switch. Should any insulator be broken or oil soaked, these can be replaced by removing the two screws holding the contacts and insulators and replacing the insulators with like thicknesses of tag board or non-conducting gasket material.

Check that breaker arm fiber contact surface is in good condition.

Installation

NOTE: If work is necessary within the oscillating and drive section, delay reassembly of the switch components until that work is completed.

  1. Place breaker arm (fig. 4) in slot in oscillating shaft and secure with plastic retainer.
  2. Resolder electrical leads to switch assembly. If connection points were not coded during disassembly, hold switch assembly with fiber cam (fig. 4) downward and with switch mounting surface away from you. Then, from left to right, solder green wire to top-left terminal closest to mounting bracket, red wire to central terminal, and black wire to terminal at bottom right side or closest to the resistor side of the switch.
  3. Fasten switch assembly with two mounting screws (fig. 4) and position as required to satisfy requirements outlined under "Switch Adjustments" earlier in these pages.
  4. Reinstall switch cover and secure with four screws.
Oscillation and Drive Assembly

Disassembly

  1. Perform all operations listed under "Disassembly of Switch" except that it is not necessary to unsolder the electrical leads to the switch. The only purpose is to remove the breaker arm retainer and arm to allow removal of the oscillation shaft.
  2. Remove snap ring shown at bottom of figure 4 and any thrust washers secured by snap ring.
  3. Remove four screws and external-teeth lock washers securing oscillating and drive section cover.
  4. CHECK THAT THE LATCH ASSEMBLY IS NOT IN PARK POSITION, then carefully tap both the oscillating shaft on which the breaker arm (fig. 4) was attached and the drive assembly shaft shown at bottom center of figure 4 out of the housing from the switch compartment side with a soft drift. The latch assembly switch arm is shown in the low speed position in figure 4.
  5. To separate the oscillating mechanism from the connecting rod, remove "E" type retaining ring ( fig. 5) from drive pin and lift out oscillating mechanism.
  6. To complete the disassembly of the oscillating and drive section of the wiper, remove the snap ring (1, fig. 12) and separate the remainder of the parts (fig. 12).

NOTE: Further disassembly of the cover and linkage should not be attempted as these parts are furnished only as assemblies for service. No attempt should be made to remove the latch assembly toggle or arm (fig. 4) as these are fixed fast in the housing. If necessary, the latch spring (fig. 4) can be changed with the toggle installed.

Cleaning and Inspection

Clean all parts except the nylon gear with cleaning solvent and air-dry. Check all parts for deformations and repair or replace as necessary.

The nylon drive gear should be checked for worn or broken teeth. If either condition is present, replace the gear.

Clean the cover and connecting rod linkage of all old lubricant and check for bent parts. Replace the cover and linkage if any faults are found.

Assembly

  1. To reassemble oscillating components (fig. 12), connect spring to drive disc as follows: Position pawl (7, fig. 12) on pin in drive disc (6), then place wire spring on pawl and catch hooked end under offset end of pawl. Straight leg of spring should be then forced against side of disc center hub as shown in figure 13.
  2. Install drive disc and spring assembled in previous step on nylon gear (9, fig. 12).
  3. Place cam and drive pin (5, fig. 12) and yoke (4) on disc as shown in figure 14. Be sure drive pin is cradled in slot on yoke.
  4. To complete the assembly of the oscillation components, place end-play washers (3, fig. 12) and retaining washer (2) on lug and secure with snap ring (1). Measure total end-play within the unit with a feeler gauge and add or remove washers (3) until total end-play is .008" or less.
  5. Lubricate between yoke, cam and drive pin, disc and at all pivot points on the cover linkage with light oil. Then place a light grease coating on the armature shaft, nylon gear teeth, and on the linkage pivot points previously oiled. DO NOT GREASE TOGGLE OR ARM.
  6. Insert drive pin (fig. 5) through connecting rod and secure with "E" type retainer.
  7. Check that toggle is not in park position, then insert oscillating shaft and gear shaft through bores in housing. Tap as required to fully seat shafts.
  8. Secure cover with four screws and external teeth lock washers.
  9. Install breaker arm (fig. 4) in slot of oscillating shaft and secure with plastic retainer.
  10. Reinstall switch components as described under "Installation of Switch."
  11. Place end-play washers as required on end of gear shaft shown at bottom center of figure 4 until total end-play is approximately .010", then complete installation by installing snap ring.

Disassembly

The motor may be serviced without disturbing other sections of the wiper.

NOTE: All number references are to fig. 15.

  1. Remove two tie bolts (1) securing case (4) to housing (10).
  2. Remove end-play adjusting screw (11) and lock nut (12).
  3. Strike the steel case (4) lightly with a mallet to partially loosen it from the motor field (9) and wiper housing (10).
  4. Insert a tool through the armature adjusting screw opening and push against the end of the armature to back off the case. This will retain the armature commutator between the brushes until ready to separate armature from the case.
  5. To separate the case from the armature while still retaining the brush springs (2) and brushes (3) in place, fashion a separator similar to that illustrated in figure 16 from heavy wire and insert behind the brush leads as shown. The steel case may then be separated from the armature while being careful not to break the electrical connections. CAUTION: Be careful not to lose thrust ball (7) from commutator end of armature (8).
  6. Once the armature is removed, insert brush retainer spring No. 5096576 between ends of brushes as shown in figure 17 to prevent possibility of pulling leads out of brushes through prolonged tension by the improvised separator (fig. 16).
  7. If necessary, remove felt washer (6) and thrust disc (5) from motor case (4). Also, the armature (8) may be taken out of field (9).
  8. Because the field is pressed into the die cast housing, further disassembly of the motor section is not recommended. However, should it be necessary to free the case assembly from the field, unsolder the field leads attached to the brush holders.

Cleaning and Inspection

  1. Inspect both the field and armature for damage due to overheating such as unsoldered electrical connections.
  2. Check that brush leads are firmly attached both to the brushes and their connections at the brush holders.
  3. Check brushes for wear. If brushes are worn to within 3/16" of brush lead, or pigtail, they should be replaced.
  4. Check contacts of circuit breaker shown at top of figures fig.16 and fig. 17. Clean as required or file lightly to remove irregularities.
  5. Inspect all leads from the brush and circuit breaker plate for worn insulation or breaks. Be sure that green lead is held to base insulator by clip to prevent lead chaffing on armature.
  6. If it was determined by inspection in step 3 above that brush replacement was required, proceed as follows:
Assembly

NOTE: All number references are to fig. 15.

  1. If leads were disconnected to separate case (4) from remainder of wiper, resolder connections according to the diagram shown in figure 18.
  2. Loop a 6" to 8" length of string around the brush spring retainer 5096576 shown between the brushes in figure 17. This is used to pull out retainer after armature commutator is inserted.
  3. Insert thrust plate (5) and felt washer (4) into bushing in steel case. Put a few drops of light oil on felt washer.
  4. If removed, start armature (8) into field (9). Twisting the armature slightly will aid in getting the armature worm shaft engaged with the nylon gear in the drive and oscillating section.
  5. Using a high melting point grease, stick the 3/6" thrust ball (7) in commutator end of armature.
  6. Holding the armature slightly extended from the field by means of a tool inserted through the armature end-play adjusting screw hole, push the steel case (4) onto commutator end of the armature. Check that the armature is fully seated, then pull out the brush retaining spring (fig. 17) by means of the string attached in step 2 above.
  7. Line up the tie bolt holes in the steel case (4) with those in wiper housing (10) and push case into position. Then secure with two tie bolts (1).
  8. Install end-play adjusting screw (11) and lock nut (12) to complete assembly.
  9. After wiper is reinstalled, adjust armature end play as described earlier under "Adjustment." The nylon slider (fig. 3) should be lubricated with petroleum jelly prior to installation of the wiper.

Door Lock

These service operations may be used for door locks on all models. However, in addition to the following operations, it is necessary to remove the door window and glass run channel, to remove the door lock from sport coupes, sport sedans and convertibles.

Operation

A rotary bolt type door lock is used on all models. Figuresfig. 49 and fig. 50 show the door lock construction and striker with the names of component parts. When the door is being closed, the lock bolt rotates as it comes in contact with the striker, until it becomes firmly engaged with the teeth at the lower end of the striker. When the door is completely closed, the locking cam, shown in the illustration, is firmly locked by the detent lever (fig. 49). To open the door, the locking cam is released so that the bolt can rotate. This action is obtained by the operation of the push button or remote control handle.

  1. When the push button on the door outside handle is depressed: the push button lever operates the intermittent lever contacting the multiplier lever and in turn lifts the detent lever free of the locking cam (fig. 50).
  2. When the inside remote control handle is operated, the connecting rod from the remote control operates the remote lever on the lock contacting the detent lever and lifting it free of the locking cam.

Locking of the door by key or by the lock rod is accomplished in the lock in the following manner.

  1. With pencil, scribe position of striker on body pillar.
  2. Remove three door lock striker attaching screws and remove striker and adjusting plates from pillar.
  3. To install, place striker and adjusting plates within scribe marks on pillar and tighten screws.

IMPORTANT: Whenever a door has been removed and installed, or realigned, the door SHOULD NOT be closed completely until a visual check is made to determine If the lock extension will engage in the striker notch. Where required, door lock striker emergency spacers should be installed so that door can be closed and an accurate check made to determine emergency spacer requirements.

Adjustments

  1. To adjust striker "up", "down", "in", or "out" loosen striker plate screws and shift striker and adjusting plates as required, then tighten screws.
  2. DIMENSIONAL SPECIFICATIONS FOR USE OF DOOR LOCK STRIKER EMERGENCY SPACERS.

Front Door Assembly

The front door may be removed with or without the hinges attached.

Removal

  1. Place suitable protective covering over front fender at door opening to protect finish, then remove door trim pad. NOTE: On bodies with manual window lifts, the trim pad does not have to be removed, if the door is to be removed with the hinges attached.
  2. Scribe location of hinge box on front body pillar or location of hinge strap on door inner panel, depending on method of door removal.
  3. On door with electric window lifts with the trim pad removed:
    • Remove screws securing electric conduit and carefully slide conduit toward front pillar exposing wire harness.
    • Detach wire harness from clips and disconnect motor leads. Disengage wiring from retaining clips and carefully pull harness from cutout in door hinge pillar.
  4. Support door and remove bolts "A" or "B" (fig. 54). Two bolts "A" at upper hinge and one bolt "A" at lower hinge are located inside the hinge box. With the aid of a helper remove door from body.

Installation

  2. Reinstall door to body with the aid of a helper. Align hinges within scribe marks and tighten bolts. Check door alignment.
  3. On doors with electric window lifts, install wire harness to door and connect motor leads. Tighten wire harness clips, make sure spacers are properly installed and attach conduit to door hinge pillar.
  4. Reseal and lubricate door as required.
Inner Panel Sealing

Some of the front door inner panel weatherseals have been changed for 1957 styles. These changes are covered 'below. Whenever work is performed on a door where any of the door inner panel weatherseals have been disturbed, the area must be resealed before the door trim assembly is reinstalled.

Figure 56 shows door inner panel openings which are sealed to prevent water leakage and possible damage to the door trim assembly.

  1. At both access holes apply ribbon of medium bodied sealer across top and down side flanges of access hole opening to provide seal between cover plate and door inner panel (1).
  2. Apply ribbon of medium-bodied sealer to access hole cover plate starting at point "2" above lower comers and extending downward and along edge of offset flange (2).
  3. After access hole cover plates are installed, seal lower offset corners with sealer (3).
  4. Apply sufficient body caulking compound to effect a watertight seal at:

All window regulator attaching holes (4).

Door inner panel cam attaching holes (5).

Ventilator division channel lower attaching stud and nut (6).

Ventilator tee-shaft access hole and ventilator regulator attaching screws. (7, View "A.")

Door trim assembly nail slots (8).

Front Door Adjustment

Door adjustment is provided at the hinges through the use of cage nuts and anchor plates. When checking a door for misalignment, remove the door lock striker and allow the door to hang free on its hinges, then check the spacing at the sides and top of the door. After determining the type of correction needed, correct in the following manner:

Up or Down and In or Out

  1. Scribe location of hinge box on pillar.
  2. Loosen bolts attaching hinge box to pillar.
  3. Shift door to desired position and retighten bolts.

Up or Down and Fore or Aft

  1. Remove trim pad.
  2. Scribe location of hinge strap on door.
  3. Loosen bolts attaching strap to inner panel, shift door to desired position and retighten bolts.
  4. Install trim pad and lubricate door hold opens and hinge pins with Lubriplate or its equivalent.

Should the door clearance at the body hinge and windshield pillars be parallel and fall within 1/16" to 3/16" clearances and the door at the center or lock pillar be tilted (close at the top, wide at the bottom or vice-versa) it is indicative of another type of correction, namely body shimming. In most cases, where adjustment of the doors cannot correct a door alignment problem, body shimming will be the answer. Figure 58 shows the location of all body mounting points and where shims may be added or removed to correct body alignment faults. In addition figure 57 gives the dimensional clearances of the doors at the pillars.

NOTE: After performing any door adjustments on a convertible or four-door sedan style the door ventilator and window should be checked for proper alignment with the side roof rail weatherstrip and adjusted where required. In addition, when performing adjustment on any style do not close the door completely without making a visual check to see that the door lock extension engages in the striker notch as specified.

Door Trim Assembly

Removal and Installation

The same procedure as used on the sedan front door except that the door belt finishing molding must also be removed.

Side Roof Rail Weatherstrip

The side roof rail weatherstrip is a one-piece weatherstrip, with an "L" shaped metal insert through the entire length of the weatherstrip. The weatherstrip is secured to the side roof rail by fourteen screws and to the body front pillar by one screw.

IMPORTANT: The attaching holes in the side roof rail weatherstrip are elongated to provide "in" and "out" adjustment for proper contact with the front and rear door window frames. However, the amount of adjustment is small and is not intended to correct for improper ventilator or door window alignment. It is very important that the front door ventilator and the front and rear door windows are checked and, if necessary, aligned for proper contact with the side roof rail weatherstrip.

The following procedures may be used for removing, installing and adjusting the side roof rail weatherstrip.

Removal

  1. Open both front and rear doors and lower the windows.
  2. Remove one screw securing weatherstrip at body front hinge pillar and screws securing weatherstrip to side roof rail. Carefully detach weatherstrip from sealer and remove from body.

CAUTION: Use care when removing and handling weatherstrip so as not to bond metal insert.

Installation

  1. Clean off all old sealer from weatherstrip attaching surfaces along side roof rail.
  2. As a bench operation, apply a continuous ribbon of heavy-bodied sealer (3/16" diameter) along the inboard edge of weatherstrip as indicated at "1" (fig. 77), along entire length of weatherstrip.
  3. At the front end of the weatherstrip apply a good grade of weatherstrip cement to the contacting surface of weatherstrip, indicated at "2"
  4. Position weatherstrip to side roof rail and retain in position with one attaching screw at front center and rear of weatherstrip.
  5. Install loosely all weatherstrip attaching screws.
  6. With the doors and windows closed, position weatherstrip so that an even, continuous contact is made with the window frames and tighten weatherstrip attaching screws. Clean off excess sealer and cement with mineral spirits.
  7. Lubricate. Apply a silicone rubber lubricant to surface of side roof rail weatherstrip indicated at "1" in fig. 77. Lubricant is to be applied along length of weatherstrip. In addition, apply lubricant to the top and inboard surface of the rear door window frame sash channel as indicated at "2". Apply lubricant to the upper front comer of the frame extending from the forward edge rearward for a distance of seven inches.

Adjustments

  1. The attaching holes in the side roof rail weatherstrip are elongated to provide "in" and "out" adjustment for proper contact with the front and rear door window frames as shown in fig. 78. To adjust weatherstrip, loosen attaching screws along area requiring adjustment, move weatherstrip "in" or "out" as required and retighten screws. NOTE: The amount of "in" and "out" weatherstrip adjustment is small and is not intended to correct for improper ventilator or door window alignment. If proper weatherstrip contact cannot be obtained through the "in" and "out" weatherstrip adjustment, the door ventilator and/or windows must be aligned to obtain the proper weatherstrip contact.
  2. The side roof rail weatherstrip can also be shimmed downward to provide proper contact with the ventilator frame and door glass frame. To perform this operation, detach weatherstrip from side roof rail sufficiently to install tapered waterproof shims between the weatherstrip and the side roof rail. DO NOT BEND THE INTEGRAL METAL INSERT. Shims should be securely cemented to side roof rail, and specified sealer should be re-applied to weatherstrip in affected area.

CAUTION: Shims should be well tapered and long enough to provide a continuous sealing surface along the length of the weatherstrip. Shims which are not tapered or too short may cause irregularities in the sealing surface.

Front Door Assembly

Assembly and Hinges

The front door hinges are the swing-out type with an integral door check and hold open, similar to the sport coupe. The hinges are attached to the front body hinge pillar and to the door assembly with bolts, cage nuts and anchor plates. Either of two methods may be used to remove the door from the body.

  1. The door and hinges can be removed as an assembly from the body hinge pillar.
  2. The door can be removed from the hinge straps.

Adjustment

Door adjustments are provided through the use of floating cage nuts and anchor plates in the door and adjacent hinge pillar. When checking the door for misalignment, remove the door lock striker from the body pillar to allow the door to hang free on its hinges.

IMPORTANT: After performing any door adjustments the front door ventilator and window should be checked for proper alignment with the side roof rail weatherstrip and adjusted, where required. In addition the door lock extension-to striker engagement should be checked and adjusted, if necessary.

Inner Panel Sealing

Fig. 79 shows the front door inner panel areas which must be sealed to prevent entrance of water and possible damage to interior trim. Whenever any work is performed on the door where the weatherseal has been disturbed, the area must be resealed before the door trim assembly is reinstalled.

Sealing Operations

  1. Apply a ribbon (approximately 3/16" diameter) of medium-bodied sealer across the top and down the side flanges to a point 1/2"' beyond the access hole cover offset line to Provide a seal between cover and inner panel.
  2. Apply a ribbon of medium-bodied sealer to the contacting surface of access hole cover at the lower corners.
  3. After access hole cover is installed, seal lower comers of cover, at offset, with body caulking compound.
