Would dielectric grease, like used in light sockets, work? Just asking the experts just in case I run into the same situation.
I don’t think I’d want to use that. It’s very thick, very viscous, but it’s still a liquid, so with enough vibration it would start to flow out of the cavity. Sounds like a bad idea in the long run.
I rebuilt a similar motor. My thought was that there must be other reasons more than insulation as to why they put so much of that black tar substance in that cavity to begin with, maybe for? heat, cold, shock, vibration etc. I dunno I’m just a rookie.
