As a tip...
Ask them if they can vacuum varnish and bake.
What this means is, the finished windings are dipped in varnish. Then the stator assembly is immersed (along with a lot of other windings) into a big tank.
The tank is pumped down to a high state of vacuum and left for a couple of hours.
Then the stator is baked to cure the varnish.
The vacuum does an amazing job eliminating micro air bubbles in the varnish.
It doesn't only insulate
It holds the windings as a matrix. making the assembly vibration proof.
I have no idea if Onan does this as the OEM.
