c. Disassembly
1. To facilitate reassembly, place parts on a
clean bench or in a clean pan in the order in
which they are removed.
2. Remove cover fastening screws (1, Fig.
10.63), cover (2), spacing washers (3), and
cable securing bracket (4) from the gear
housing.
3. Remove parking switch assembly (5). If the
parking switch is to be replaced, unsolder all
leads from the plate.
4. Remove cable assembly (6) if replacement is
necessary.
5. Remove gear and shaft assembly (7) and
spacing washer (8) from the drive shaft.
NOTE: If drive gear housing or motor housing is
damaged beyond repair, replace motor assembly.
d. Cleaning and Drying
1. Clean the gear and shaft assembly (7) and the
armature shaft worm with Varsol or equivalent
cleaning fluid.
IMPORTANT: Bearing equipped parts must not
be immersed in the cleaning fluid. These parts
should be cleaned with a brush dipped in the
cleaning fluid, making certain that the cleaning
fluid does not contact the bearings.
2. Thoroughly dry all parts that have been in
contact with the cleaning fluid.
3. Clean the parking switch using a clean dry
cloth. Remove all traces of lubricant from the
contact spring and grease or oil from the
insulation plate.

e. Inspection and Replacement
1. Inspect parking switch assembly (5, Fig.
10.63) for security of soldered connections,
cracked or damaged plate, loose terminals,
damaged or frayed cables, loose parking stud,
and misaligned contact points. Spring height
must be as indicated in Fig. 10.64.
2. Inspect gear and shaft assembly (7) for
damaged or worn gear teeth, damaged
threads or worn flats on the end of the shaft.
Replace gear and shaft assembly if damaged.
3. Replace motor if motor housing is damaged.
4. Inspect drive arm assembly (28, Fig. 10.62) for
wear, loose pin and cracks. Replace drive
arm assembly if damaged.
5. Inspect connecting link (26) for worn bearings.
Replace connecting link if damaged.
6. Inspect shaft and pivot assembly (24) for
damaged threads and loose drive arm.
Replace damaged parts.
7. Inspect spring clips, screws, nuts and washers
for serviceability. Replace as required.
f. Lubrication
As the parts are being assembled:
1. Lubricate the gear housing by filling the space
between the bearings in the drive shaft bore
with Electro Systems LU3001 grease.
• Place a sufficient amount of grease in the
worm gear cavity to immerse the lower 1/
8" of the drive gear.
• Apply a thin film of LU3001 grease to the
portion of the housing that contacts the
drive gear. Apply two or three drops of
SAE #10 oil to the felt packing surrounding
the armature shaft bearing.
2. Lubricate the gear and shaft assembly (7, Fig.
10.63) by applying a thin film of Electro
Systems TSE52115 to the cam and recessed
portion of the gear face. Apply a thin film of
Electro Systems LU3001 grease to both sides
of the nylon spacing washer (8).
