Read the general procedures before proceeding, refer to section 4.3.1.
- Remove dome nuts (36), front cover (38), rotor retainers (35), rotors (41)
and front cover o-ring (39), see section 4.1.
The seal can now be accessed for inspection.
- Remove the rotary seal face assembly from inside the rotor, taking care
not to damage the o-rings.
- Remove the stationary seal assembly from the rotorcase by releasing the
retaining nut (12). Note that there is an anti-rotation device incorporated
into the rotorcase (not shown), when replacing the seal, alignment
between the seal and rotorcase must be achieved to prevent rotation.
Note: Extreme care should be taken when carrying out these procedures
to ensure that the seal faces are not damaged. If seals are being refitted,
ensure that seal faces remain matched.
- Assembly is the reverse of the above procedure, ensure that all faces are
clean and free from damage.
