Disassembly (Fig. 49)
1. Plug motor ports and clean the outside of the motor
thoroughly. After cleaning, remove plugs and drain any
oil out of the motor.
2. Use a marker to make a diagonal line across the
front plate, body, and back plate for assembly purposes
(Fig. 50).
IMPORTANT: Avoid using excessive clamping
pressure on the motor housing to prevent distorting
the housing.
3. Clamp mounting flange of motor in a vise with the
shaft end down.
4. Loosen cap screws from the back plate.
5. Remove motor from the vise. Turn motor so that the
shaft end is facing down. Remove cap screws.
6. Remove back plate from the body.
7. Carefully remove body. Lift body straight up to re-
move. Make sure the rear wear plate remains on the
drive and idler gear shafts. Remove and discard o--rings
from the body. Locate and retrieve dowel pins.
