Re: (ET) Pulling bearings on mower motors - Thank You Dean & Chris !

Cool! Glad to hear you got them off, I still have one hub that is 
totally frozen on and thinking about alternatives. Hate cutting the hub, 
but it might be the last resort.

I normally put the armature in a vice, not too tight, then put the 
puller on top and turn with a socket wrench. The vice keeps the armature 
from turning so the puller doesn't move either. This works for large 
motors of course, not the small ones.

Tried firing up the destroyed magnet motor and it WORKS. I can't believe 
it. The new brushes are seriously noisy, need to see if that's the brush 
or the top bearing. Your idea of running the bearing up against the wire 
brush of the grinder is a good one, I'll do that.

The other tall thin motor is also... a challenge. The alignment pin on 
the top broke off so I have to drill that out, more little things to do.

For the brush holder, I just use a small jewelers file to smooth out the 
inside of the brush assembly and the new brushes slide in with no 
binding. Important as you don't want them to stick.

Now I just have to figure out how to get the top bearing out of the top 
brush holder (that's where it went). been soaking in penetrating oil all 
night will try this evening. Never dull....
