Product review (2 stars): Thicker coupler, caused burning smell.
I have a circa 1993 Kenmore 60 series washer.  I've made this same repair once before many years ago.  This coupler is a little bit thicker or deeper than my original.  The added thickness made it difficult to reseat the motor.  When I placed the motor over the new coupler, the motor's four rubber feet did not all seat into their depressions on the bracket.  And it was very difficult to compress the motor in place so that the motor clamps could be reconnected over the motor.  When I got everything back together the machine ran the full cycle properly but it emitted a burning smell during the spin cycle.  I ran a few more cycles but the burning smell persisted.  I took the motor off again and the new coupler looked fine.  When I put everything together the second time I used only one plastic end from the new coupler and I used the other parts from my previous coupler.  This reduced the thickness enough that the motor seated onto it's bracket properly and the motor clamps went on easily.  Now my machine runs with no burning smell.  I believe the extra thick coupler caused the motor to be either too tight or misaligned, which put too much load on the motor, which caused the motor to overheat and begin to burn.  I recommend that if your motor doesn't seat and clamp easily with this coupler than don't use it.
