Sorry for the dramatic thread title, but that is what woke me up this morning. I'm already very late for work (luckily, it's a slow day) so I'll keep this short and let the pictures do the talking.
Facts:
1. The pulley broke
2. Service company wants $500 to fix "it," not really understanding what "it" is, apparently.
3. I've pulled the motor from the sliding mount and will bring it to work with me to see what the guys think. We all work much better hands-on.
4. The blower motor spins freely and will continue to spin with only a minor tug.
5. The motor spins freely, but it will not continue to spin much after you stop imparting rotational force. There does not appear to be excessive play, and the friction is probably just old, but adequate lubrication and gunk.
If I have time I'll answer any questions, but here are my questions:
1. How do I get the pulley off? There are two set screws, one for the pulley to the threaded piece and the other to the rotor shaft.
2. Is there any way I can JB Weld this bad boy back together? Notice the wear pattern on the broken piece. The belt doesn't touch the base of the pulley.
3. Any other recommendations you guys have RE: pulling the bearing apart and cleaning/lubricating?
AS YOU CAN SEE, IT WAS A BRITTLE FRACTURE, WITH LITTLE ALMOST NO DEFORMATION - THE PIECE OF THE PULLEY THE BROKE OFF FITS BACK, LIKE A PUZZLE PIECE:
