Removal of Single Mechanical Seals.

Ensure pump is fully shutdown, refer to section 3.5.

To remove single mechanical seals, reverse the above procedure using
the extraction tool (61) to aid in the removal of the seal faces, see fig
27.

Note: If seals are being reused, ensure that seal faces remain matched.

With reference to fig 26 remove rotary seal faces (33) from rotors (41)
using the extraction tool (61). This is achieved by inserting the
extraction tool between the rotary seal face (33) and the rotor (41)
applying a twisting action, see fig 27. It may be necessary to alternate
from side to side in order 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.
