Product review (4 stars): Its RIGHT IN THE MIDDLE ;-)
I'm a handyman, sure I'll replace a busted 'clutch coupling housing assembly' in a washing machine.  How hard can it be?  Wasn't hard, (ok, one nut was tough) but I would have liked 'you don't need to remove the tub bolts' written down somewhere.

Installed and worked fine.

A c- on the design, that single 1/2" gear shaft is expected to take a lot of force and who knows what caused it to snap - but it did.
