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.
Note position of the open and closed side of the thrust plates before
removing. Identify thrust plates (front and rear, drive gear and idler
gear) with a marker for proper assembly.
Mark the relative positions of the gear teeth so they can be
reassembled in the same (mated) position. Do not touch the gear
surfaces as residue on hands may be corrosive to gear finish.
7. Carefully remove body. Lift body straight up to remove. Make sure the rear
thrust plate remains on the drive and idler gear shafts. Remove and discard
O–rings from the body. Locate and retrieve dowel pins.
8. Carefully remove rear thrust plate, idler gear, drive gear and front thrust
plate from the front flange.
