4. With the impeller/shaft assembly removed from the
pump, place the pulley (1) on supports (2) and press
out the shaft assembly (3) from the pulley.
The seal assembly attached to the bearing shaft is
not removable or serviceable. During the manufac-
turing process, the seal is pressed onto the shaft and
destroyed on removal. This is to meet pre-load con-
ditions and maintain an effective wear seal.
5. Inspection and Repair
Check the bearing shaft and seal assembly for signs
of wear or leaks and if evident, the assembly must
be replaced with new parts.
6. The impeller should be checked for worn or damaged
vanes and must be replaced if not to an acceptable
standard.
7. Clean and check the pump body for signs of cracks,
erosion or leaks. If any of these faults are in evidence
and likely to cause pump failure at a later date, the
pump body must be repaired or replaced with a new
one.
