Product review (4 stars): Replacement 285753A - Washer Motor /Transmission Coupling
I received the replacement ("Jason" branded) coupling in good order - the shipping/delivery time was less than a week. Upon receipt of this new part, I removed the original (failed) one from the washer motor and transmission shafts, and installed the replacement. It was necessary to lightly tap the coupling end-pieces onto the motor and transmission shafts using a hammer and drive socket, due to the interference fit. I would note that, in my case, the OEM coupling functioned nominally for over 25 years, which is a substantial time period. Also, the old coupling failed in the most typical manner, in which the plastic spikes were sheared off - presumably from cyclic fatigue and aging of the plastic materials.

I acknowledge that there are multiple reviews/comments here that question the quality and design/robustness of the new coupling. Therefore, I would point out that unless it's determined that the original part failed as a result of many cycles of nominal loading and aging, installing a new coupling wouldn't correct the underlying issue. If the transmission or other components in the drive train (excluding the motor itself) have developed excessive friction, this could immediately overload the coupling and cause it to fail again - even with very little use. In this case, it may be that both the original and replacement couplings failure is unrelated to this new component design.
