Chev 216 loose piston pin - which one ?

[Hendrik van Oorspronk]

I am almost sure it is the Pulley/balancer in front of the crankshaft, my C60S had the same problem(I think). The pulley is riveted together and there was some play on de rivets.

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 ?

I spent a little time today facing the water pump seal . There must be lots of ways to do this type of job, I used what I had . Took about .010" off the face .

I plan on using a modern mechanical seal , instead of the 1940's era seal. The modern seals have a hard ceramic face, and they perform much better than the old seals .

Never use wheel bearing grease in a water pump , the temperature is too hot , and it will melt out , and run dry . Use special water pump grease ,like what you have to put in a Dodge screw in lubricator

Wheel bearing grease is high temp rated , that is why I am using it . I don't agree with your theory , sorry

BTW I suggest that you do some research before splurting out incorrect information .

hi Richard

This the grease I have used in the water pump bearing . It is rated to 200 C ..is that high enough ?
