K&T 2HL Coolant Pump Parts

[MyLilMule]

I am in the process of rebuilding the long neglected coolant pump for my K&T 2HL. There are a couple of parts that I need to replace. Perhaps one of you faced something similar and came up with a solution.

The spring that sits behind the pressure relief valve was rusted in place and is broken. I am looking for a suitable replacement. My search on McMaster didn't come up with anything. It appears to have bee 4" long, has an OD of 0.750", and a wire diameter of .0625", with perhaps 7 winds per inch.

The other thing is the pickup strainer. It had crumbled do nothing when I pulled the pump out. There were some pieces remaining, but most of it was gone.

Any help anyone could be would be appreciated.

Coolant strainer I got a replacement from Hugh Head (https://hughsmachinery.com/) recently. He had both new and used ones for my machine (205sa).

He might have the springs too. Mine was ok.

On mine I also surface ground the backplate of the pump to eliminate scoring and turned a new bronze shaft for the driven gear (and bored out the gear ID to eliminate scoring).

Thank you. I sent him an email.
