Flushed Hyclean Seal Replacement

– The seal rotary face is driven by a pin which locates in a slot on the shaft. A washer is located between the shaft shoulder and rotary face. A seal between the rotary face and shaft is provided by an 'O' ring.

– The stationary face is prevented from rotating as it has a flat side which sits in the rotorcase bore. Face to face contact is provided by a wave spring.

– Axial movement of the stationary face is prevented by a retaining clip. An 'O' ring within the rotorcase bore provides a seal onto the stationary face.

– A seal housing encloses the hyclean seal and is seal by an 'O' ring and retained to the rotorcase by socket head cap screws. A lip seal sits within the seal housing and runs on the rotary face, thus providing a seal.

CAUTION! SEAL FACES ARE BRITTLE - TAKE EXTREME CARE WHEN HANDLING. REMOVING THE FLUSHED HYCLEAN SEAL

REMOVING THE FLUSHED HYCLEAN SEAL

1. Carefully support and remove the rotorcase with the seal housing and stationary face still attached.

2. Slide the rotary face from the shaft.
