most importantly the guy with two stink bombs in his garage. Not much stink left now and their r124 future will be much better smelling.

We got the stators back and are researching proper wire for the motor leads. Garrett counted the strands in an original and came up with over 100/36. Flex is an issue as they get moved, but also as they start and stop.

The one thing I worry about is the silicone. It doesn't look like it does well in many/most fluorocarbons. Here's the chemical compatibility section from chemours:

I can attest that silicone O-rings swell up and soften until they are the consistency of overcooked spaghetti when used with certain refrigerants. Voice of experience I hate to say.

I deleted my earlier post about ordering silicon insulated wire as David has pointed out material incompatibility with R124. We're going with other material that Garrett has access to.

I'm sorry to be the bearer of bad news. First I had ruined your Westy compressor with a grinder; and now this! (LOL)
Actually I believe Aaron pointed it out first, just that I had a firsthand experience with it.

I'm glad you found out before it was installed . It we’ll be great to see this one back together and working.

This is just an update on our progress.
Garrett found some uninsulated high strand count lead wire to replace the conventional leads with. I've reached out to a company that makes the tubing to sleeve the soldered connection and the lead down to the terminal. I've made them aware that the stator was wound to class H and would be used with mineral oil and R124.

If you don't mind my asking Travis, why was this particular top rewound in the first place? That is, what problems were occurring?

Paul,
It had been rewound with Teflon insulated wire to be compatible with SO2. Unfortunately, the insulation was breached and the SO2 attacked the wire.
This time, it got rewound with conventional material and will use R124.
