CAUTION: It may be necessary at this point to

rotate armature slightly before the armature

worm will engage with worm gear teeth.

Rotate the case as required to align the bolt holes in

the case with those in the housing.

Secure the case to the housing with the two tie bolts.

GEAR BOX SECTION
Fig. 88 - Drive and Lock Pawl Guide Pins in Pockets

(drive pawl away from latch arm, fig. 81), proceed

to Step 3.

Remove relay-switch attaching screw (fig. 80) and

carefully lift the relay-switch assembly out of the

gear box. Unsolder leads from switch terminals as

required. Refer to Figure when resoldering leads.

To remove terminal board assembly simply slide it

out of housing and unsolder leads as required.

The gear box section is subdivided into two areas, (A)

the relay control and latching mechanism and (B) the

drive gear mechanism.

A—Relay Switch and Latch Assembly-

Terminal Board Removal

1.
Remove screws retaining washer pump assembly to

wiper unit.

2.
If wiper pawl is in full park position (drive pawl lo-

cated in magnetic switch assembly slot, fig. 79), it

becomes necessary to remove gear assembly first

(see Gear Assembly Removal).

If wiper gear mechanism is not in park position

and test wiper and washer assembly for proper

operation.

WIPER TRANSMISSION

REMOVAL AND INSTALLATION

1.
Remove wiper block and arm assembly from trans-

mission.

2.
Remove glove box door and compartment assembly.

Refer to Section 1 for removal procedures.

3.
Remove three transmission-td-cowl retaining

screws.

4.
Remove wiper transmission retaining clip and re-

move transmission from crank arm. Then remove

transmission through the glove box opening.

5.

WIPER ASSEMBLY REPAIRS

The overhaul procedures for the wiper are broken down

into three major areas: The motor section, gear box

section and washer pump section. Each section may be

serviced independently of the other.

MOTOR SECTION

Disassembly

1.
Remove the two motor tie bolts.

2.
Remove the armature end-play adjusting screw (fig.

91).

3.
Strike the steel case lightly with a mallet to partiaUy

loosen it from the die casting housing and motor

field.

4.
Insert a tool through the armature adjusting screw

opening and push against the end of the armature

shaft to back off the case. This will retain the ar-

mature commutator in position between the brushes

until ready to separate the armature from the case.

5.
To separate armature from case while still retaining

the brush springs and brushes in place fashion a

spring similar to that shown in Figure 95 and insert

behind the brush leads as shown.
Fig.
95 - Retaining Armature Brushes

6. Pull the armature out of the case and remove the felt

washer, thrust plate, and rubber thrust disc from the

case assembly bearing as required.

7.
The field windings are pressed into the gear housing

and further disassembly is not recommended; how-

ever, the field leads may be unsoldered from the

brush holders to remove the case.

8. Clean and inspect all parts.

Inspect both the field and armature for damage

due to overheating such as unsoldered electrical

connections.

Check that brush leads are firmly attached both

to the brushes and their connections at the brush

holders.

Check brushes for wear. If brushes are worn to

within 3/16" of brush lead, or pigtail, they should be

replaced.

Check contacts of circuit breaker shown at top of

Figure 95. Clean as required or file lightly to re-

move irregularities.

Inspect all leads from the brush and circuit

breaker plate for worn insulation or tjreaks.

If it was determined by inspection that brush re-

placement was required, proceed as follows:

a. Remove retainer installed during disassembly and

remove brush springs.

b.
Place a hot soldering iron against*brush lead con-

nection on brush holders, remove old bushes, and

nection on brush holders, remove old brushes,

and install new brushes.

c. To reinstall brushes in holders, compress spring

within holder and hold fully compressed with a

thin instrument inserted through the slot in the

brush holder. Then push brush into holder with

lead upward to project through slot in holder, hold

NOTE: it may be necessary at this point to

rotate the armature slightly before the worm

will engage with the worm gear.

5.
Rotate the case as required to align the holes in the

case with those in the housing.

6. Being very careful not to pinch any of the motor

leads between the case and edge of the field, push the

case onto the field until it butts against the housing.

7.
Secure case to housing with two tie bolts.

8. Install end-play adjusting screws and locknut and

adjust end-play by tightening adjusting screw finger

tight; then back off screw 1/4 turn and tighten

locknut.

GEAR BOX SECTION

The gear box section is subdivided into two areas, (A)

the relay control and latching mechanism and (B) the

drive gear mechanism.

A—Relay Control and Latching Mechanism:

Disassembly

1.
Remove four screws which secure the washer pump

assembly to gear box.

2.
Refer to Figure 97. Disconnect coil spring, remove

"E"
ring and lift the latch and follower assembly off

the pivot pin and relay armature.

3.
Remove the stop assembly retaining screw. This

will permit the stop assembly to be moved as neces-

sary to allow clearance for removing the relay con-

trol assembly.
Fig.
100 - Assembly Gear and Eccentric Shaft

4.
Remove the two screws that secure the relay control

assembly.

5.
Lift the relay control assembly out of the gearbox

and unsolder leads as required.

Reassembly

1.
Solder existing green and yellow wiper leads to relay

control switch and solder the relay coil Iea4 to the

wiper unit terminal board as shown in Figure

B—Drive Gear Mechanism:

Disassembly

Refer to Figure 84 unless other wise specified.

1.
Remove the crank arm retaining nut (No. 1).

2.
Remove crank arm (No. 2), snap ring (No. 3) and

rubber seal (No. 4).

3.
Remove the retaining ring (No. 5), end play washers

(No.
6), shield (No. 7) and spacer washer (No. 8).

4.
