Chev 216 loose piston pin - which one ?

Back to the pump rebuild

Before I continue with the description and pics . This mod to my water pump was done without any permission from anybody. It is my pump and I do with it as I wish.

That is enough sarcasm from me .

I decided to ditch plan A and go to plan B

I bored out the pump housing on my mill/drill, using a home made boring head .

The seal is a two part seal as used in swimming pool pumps and fire fighting pumps and myriad other applications , these seals are easy to buy and are known as 'mechanical seals ' . I used a 5/8" seal .

Any machine shop can do this simple mod .

The last thing is to machine up an adapter for the ceramic seal, to fit it into the impeller

Thats it
