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. Separate rear cover from body. Lift rear cover from motor.
7. Carefully remove body. Lift body straight up to remove. 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.
Note position of the open and closed side of the wear plates before
removing. Also, identify wear plates (front and rear) with a marker
for proper assembly.
Mark the relative positions of the gear teeth and the wear plates so
they can be reassembled in the same position. Do not touch the gear
surfaces as residue on hands may be corrosive to gear finish.
8. Carefully remove rear wear plate, idler gear, drive gear and front wear plate
from the front flange.
9. Remove and discard back-up gaskets and pressure seals from wear plates.
