I am working on a motor that has plastic wrist pin pads that are worn out. What would be a good material to make replacements from? I am thinking about using delrin (Acetel) , but I was wondering if there is something better. The liner is an ABN

Teflon is higher temp than Delrin.

I just looked on the mcmaster-carr website and they list PTFE rod that has a temp rating up to 500f .

Teflon is very easy to machine, much like Delrin.

Use either one, they both work OK

I have used the PTFE from McMaster. It is very soft. Once you turn the diameters, just slice it off to length with a good Xacto. Much better than trying to part it off. If you use nylon, use the Delrin, not 6/6 or the like. The Delrin machines mucho betterro.

Of course, if this is all old news to ya, forgive my comments, Big Mike!
