Its always a daymaker when its gold color inside and a sad day when its majority all silver color insides why do they use aluminum and other times copper ?
i dont even try to get the shaft out,, i remove the 4 long bolts, usually a impact will do it while u hold onto nut with other hand,, if not angle grind the top of bolt off, real quick ,, hammer the AL end off,remove the 3 bolts holding motor to blower and remove motor, it usually slides right off leaving armature in side,, the AL end is easy to clean up, i use a 20 inch long flat screwdriver to pry off inside steel cap ,then a piece of rebar sliding through to knock off the dirty end cap, and a 10mm socket to hammer out sintered bearing, then u have clean AL casting.if you must remove shaft they make 8 point sockets for square headed bolts, or use a open end of a combination wrench of the right size,i save oil from ac compressors, u can use that to lube up shaft let it sit , then use a 5 pound sledge to slam against end of shaft , i should fly right out , but i would remove AL end cap opposite shaft first.
Done several of them in my life, some of them aren't easy, depending on how easy the shaft comes out of the swirl cage !! Good job jimbo !! #3 sheet copper here. My local yard sucks
those blower motors... some are easy as pie, others a real pain. recently had one that was a pain in the ass, then the motor windings turned out to be al. 35 lbs of sheet copper, nice, that's a lot of stripped wire... i'll find some nice copper tubing once in a while, usually all green and dirty, i'm guessing they don't know it's copper and toss it, but the trained eye one day i saw a bunch of copper tubing sticking out of a garbage can... it was a copper colored garden hose. one night i saw what looked like a couple pieces of plywood leaning on a garbage can, checked anyway, it was two thick metal plates, about 200 lbs of clean steal.
