Chev 216 loose piston pin - which one ?

[Jordan Baker]

Mike, back on the first page of your post you had some great pictures of rebuilding your water pump. You replaced the original seals with a modern mechanical seal. I'm just wondering how it all turned out once it had been in use?

Is this the type of seal you used?

Hi Jordan

I have been running the engine regularly, mainly in order to keep it all from gunking up, the modern fuel is crap and it clogs evreything up if you leave it .

The water pump mod has been great , no leaks in over 2 years. Yes those mechanical seals are easy to buy. I used the 5/8" one from memory.

I picked up a couple of the 5/8" mechanical seals. Is the ceramic part supposed to be a loose fit on the shaft? I got 5/8" but it seems loose to me. What did you make the adapter out of to fit the ceramic part into the impeller?

It was a while ago. I think I machined up a sleeve out of stainless steel for the ceramic half to have a snug fit into the impeller . The ceramic half will stay put in the impeller ( not spin ) because it is held in place under tension from the spring and the neoprene surround sleeve will help it to grip . Yes the ceramic ring is a loose fit on the shaft . Look at my post with the pics.
