Product review (5 stars): Fixed my washer problem!
My washer wasn't agitating even after I replaced the dog agits. Come to find out the plastic "gear" teeth at the top of this piece had worn out, so the motor gear teeth couldn't connect with anything to move the agitator. Thankfully I discovered this without paying someone to come and tell me. The part was delivered faster than expected, which struck fear into the hearts of our dirty clothes piles. Thanks!
