Why is my Kenmore washer emitting a burning odor after replacing the motor coupler?

I replace the motor coupler on my Kenmore washer model 110.28902790. It works fine but putting off a burning smell. Whats up? I took the cabinet back off and felt the pump, motor, & gear box and none of them were excessively hot. Could I have gotten some dust in the motor, or perhaps some of the shavings off the old coupler? Or is the new coupler now putting extra strain on the motor and/or gear box?

Joey,

THANK YOU SIR!! After replacing the coupling, which is a very easy task for anyone to do, I did not get the new coupler halves seated on the motor or input shaft. The smell of burned rubber & super hot motor lead me here. Thanks for you post!!

damack here--answering my own question. After expert Joey S. answered my question I took the washer back apart and inspected the new coupler. The rubber isolator was beginning to warp after running only two loads of laundry. This indicated to me that the plastic portions were not seated on the shaft of the motor and the gear case completely. The new couplers have a metal sleeve in the center of them where they fit over the shaft, and fit much more snugly than the original coupler that was made entirely of plastic. The new coupler cannot be pushed on by hand far enough to be flush with the shaft. I found the female end of a 3/8" drive socket extention is the perfect diameter to place on the metal sleeve at the center of the coupler and then use a wrench or small hammer to tap lightly on the other end of the extention until the shaft is flush with the inside surface of the coupler. After seating the coupler in this manner it also went back together much easier. Problem solved.

The odor is likely emitting from the new motor coupler or the washer is overloaded with clothes. If the plastic portions of the motor coupler are not pushed up flush with the end of the motor shaft or pushed up flush with the end of the gear case input shaft it can cause excessive friction between the rubber isolator and the plastic couplers and cause it smell. Also make sure the motor is sitting flat in relation to the motor bracket. You do not want the motor leaning off center in relation to the gear case input shaft. Once you have confirmed the motor coupler and motor are re-installed correctly, the odor will likely go away with use.
