solvent. Make sure parts and work area are clean.

pressure ports on the motor or put metal threaded caps
on the fittings in these ports.

five (5) gallon container, attach a hydraulic load (hand
pump) or compressed air to the case drain port.
6. With the motor shaft pointed away from you into a
clean five (5) gallon container, gradually apply pressure
to the case drain port. The seal should come out of the
motor seal cavity.

o
holes in face of seal 180
