The washer fit perfect.

Excellent as always

These 3/4 moon top shaft washers are a wonderful invention. Rather than have to remove parts and slide the top shaft over, you can simply ensure that the rest of the old washer is removed and push this washer into place - literally less than 30 second install! And they are well made, no mold marks, and instantly take up the play in the shaft. Brilliant!
