Remove rotary seal faces (33) from the rotors (41 see fig 5.6) using the
extraction tool (61). This is achieved by inserting the extraction tool
between the rotary seal face (33) and the rotor (41) and applying a
twisting action, see fig 27. It may be necessary to alternate from side to
side to facilitate removal.
-
The static seal face (31) can be removed by using the same technique.
Note: Extreme care should be taken when carrying out these procedures
to ensure that the seal faces are not damaged. No excessive force is
necessary if the extraction tool is used correctly.
