I turned the dryer drum backwards hunting for a coin. The idler pulley came loose. I've disassembled the dryer and have access to the part (kind of like a bent "J" with the pulley on the long end. No bolts or anything else in sight and nothing appears broken or bent or scratched. I have farm equipment background as a youth and can't figure out how to hook back the idler pulley! A good schematic might help and am now looking for one on line. The Repair Parts List, etc. that came with it don't show how to attach this to the bulkhead. It's a Kenmore Series 80, Model 110.62802101.

Since I wrote the above, I found a schematic that showed the solution and it's working now.
