Product review (5 stars): bearing seal kit
a little work getting old bearings out not to bad. I used a piece of stock 1" x 1" x 18"long an a 3lb sledge to hammer them out. Clean the rust around the hole bearings go right back  in. Seal was about 1/8 th thicker than the old one so I had to add a washer or two so the pulley and the belt stay aligned with the motor. Otherwise the belt will slip off. So far so good every thing been running great nice and quiet again. Its was well worth the effort to do it myself.
