Stupid question ... no, make that ~ignorant~ question (as the song says,
ignorance can be cured, but stupidity is forever).
My mower motor bearings are ~rough~. After Matthew Magda's sad post
about his broken motor magnet, I decided not to tempt fate any longer.
Hmm, how do I change the bearings in my mower motors? Getting to the
rear (top) bearing seems easy -- take off the end cap, remove the nuts
and brush carrier, and there it is. (Does it just lift out? I haven't
tried yet.)
But the front (bottom) bearing is not so obvious. Do I have to pull the
blade mount off the shaft? What kind of puller do I need? How do I
replace the blade mount when I'm finished? Once the blade mount is
pulled, does the armature just pull out of the housing?
I want to do this right, and not destroy an expensive motor in the
process. Please help, and thanks for the coaching!
