Disassembly (Fig. 71)

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 flange and body for assembly purposes (Fig. 72).

IMPORTANT: Prevent damage when clamping the fan motor into a vise; clamp on the front flange only. Also, use a vise with soft jaws.

3.Clamp front flange of motor in a vise with soft jaws with the shaft end down.

4.Loosen cap screws from the rear cover.

5.Remove motor from the vise. Turn motor so that the shaft end is facing down. Remove cap screws.

6.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.
