Good replacement part.
Good replacement part. The hole seems just a little too big around, but it functions flawlessly. I have no OEM part to compare it to, and I am not a professional mechanic so that is just my assumption.

Hello Robert, thank you for writing. We do sell the Bolt And Washer Assembly part 532193003 that help to secure the blade. This is a Right Handed Bolt and normally takes a 15/16 wrench to replace the blades. We hope this is enough information. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you.

Not knowing the extend of the damage I order all new parts to build an new housing (Mandrel) complete with shaft bearings and blade. Parts were exactly the same as original and fitted perfectly. Had a little trouble getting the old one off, had to break off the bolts that took some doing, but putting the new one together was a breeze. Thanks for the reasonable pricing.
