My 68Z Pump! - Gone done by ME!
Sometimes you just end up kicking your own arse
It was dated 66' and was serviced at some point. I ended getting a 1967 dated correctly from a vendor. They (GM) went to a larger Bearing in 1970' I think and making sure you get the correct kit is important. Then Properly Setting the internal seal is tricky that required special tooling

Wow,all good inputs. I appreciate yr suggestions and YES I did add an extra “5” in my part number. Good catch. I’ll report back on which direction I go.

Thanks again!

Best,
Sam

YOu are a courageous man showing a sad outcome but, you’re willingness to show the rest of us so we can learn from you is noteworthy. I doff my cap to you sir!!

Update. I have a GM aluminum water pump due here this week. I received the rebuild kit from 2ndGenAutoParts. I also got their 3D printed special tool to install the bearing to the shaft.

Ignore the hub in attached photo - they substituted the correct 8-hole hub in my kit.

Any best practices for cleaning up the aluminum pump?

Thanks!
