-
Remove the rotary seal face assembly from the shaft.
-
If required, remove the seal housing (67) from the rotorcase by releasing
the retaining nut (12), care should be taken as the stationary seal face
may still be installed.
-
If required, extract the stationary face from the seal sleeve, exposing the
O-rings. Note that there is an anti-rotation device incorporated into the
rotorcase (not shown) when replacing the seal housing (67), alignment
between the seal sleeve 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
