If its a maytech 6396 motor @brown5tick might know whats wrong. Ive heard he had to replace a bearing too one time, not sure it was due to water damage though.
Edit: seems like a similar problem
My big bearing has completely seized up after a particularly wet and muddy session. Any tips on cleaning or replacing it? I can’t figure out if there’s a dust-cap on it (it’s not budging if there is).
I’m surprised to see how much corrosion is building up there as well. Is it worth brushing this back and then sealing it with conformal coating or something?

It’s a 6809Z.

I soaked it in oil for a day or so have flushed it through a few times. Now it’s spinning quite nicely again.
Reassembled it. Now I’m hearing what I’m guessing is a rubbing between the can and the stator. Can was thoroughly cleaned and oiled and looks perfectly aligned so don’t know wtf is up now.
Problem categorically was the bearing. There was no can/stator rub. Pulled it off and replaced it with an SKF 61809/6809 2RS1. It’s like night and day. Smooth as silk.

Recently I’ve semi broke several maytech ‘extra tough’ style motors that have a 6809z bearing at the stator/can interface.

I’m trying to remove adjacent parts to examine the coil termination area directly.
I pissed away a whole afternoon working this out. I made a tool to push the stator away from the bearing.
I didn’t want to mar the black anodized surface that seats the big bearing. Also, windings are precariously close to the inner face of that bearing to try to us…
