Personally I would never use an impact wrench on a puller as you have no idea on how much stress you are putting on things. Could be a real safety issue if something broke.<div class=""><br class=""><div class="">

I never timed it but I would guess 1-2 hours per motor and that includes taking them off and on the deck.<br class="">For very stubborn bearing pulls a have another trick for you. Crank the puller tight and then use an air chisel with a blunt tip punch on the end of the puller. I keep a 1/2 drive socket on the end of the puller as a guide for the punch so the air chisel stays on the end of the puller when you pull the trigger. The combination of the pullers tension and a couple brief rattles of the air chisel gets even the most stubborn bearing moving.<br class="">Page 8-3 of the Home Owners Service Manual shows the following<br class="">Small motor.

They don’t describe what that is made of. Looks like a snap ring for the large bearing in the photo but it is not called out as a separate part.<br class="">Speaking of bearings. I just replaced the bearings in my METI deck motors. I was talking to our local bearing store techs and he suggested LLU seals for the deck motors.
