That hasn't been my experience with the Mitsu units, in either case. The field coil insulation has held up fine to solvent type degreaser, brake cleaner, shellite. And the sealed bearings have been darned near indestructible, even a twice flooded unit wasn't impacted by water or dirt. Front is a common $7 unit if required, SRE bearing about $22.

I like to see a frugal outcome that works just as well, when possible. And if I go overboard with a process like wet blasting a casing, that's another $60 staying in Australia for Aussie labour, not going to an importer of replacement units made in China.
