Product review (1 stars): The heavy duty coupler has a metal collar that slips ...
The heavy duty coupler has a metal collar that slips over the shaft versus the standard solid plastic coupler. So I thought it would be stronger and less likely to break. I changed the coupler and clutch and 7 washloads later the coupler had broken. The metal portion was ok but the plastic yoke fractured. I think the metal collar leaves the plastic thinner, weaker and more fracture prone. I reinstalled the old solid plastic yoke ,that hadn't broke and it has been working ok. Perhaps there are other problems with the washer/transmission but the heavy dutycoupler wasn't the solution! I will buy the non-heavy duty model next time.
