Pump
I managed to disassemble the water pump.
These pumps are a pain to work on. A shop press is needed and it is very easy to damage the cast housing of the pump if too much pressure is applied ( been there , done that ) ,a fracture results , rendering the housing useless . In this case heat was applied to the impeller in order to release it from the bearing .
It is most important to use a sleeve over the pump housing while pressing on the bearing shaft . I machined up a sleeve .
A puller is needed top remove the fan hub , if the hub is really stuck, it can bend under the pressure from the puller .. Ive done this too !
The seal surface in the pump housing needs to be cleaned up , it has wear ridges and score marks .
This is a single hole pump . Not sure if the later CMP's used the two hole type ?
