Questions & Answers for Key: 3/​16 X 5/​8


Is this a correct fit with above mentioned model? I have seen square shaped and another Is like 1/2 moon shaped. Any difference between the two shapes. Thanks
Joe for model number Kholer 21 sv 610-0212 asked on 2022-04-30
Hi Joe, Thank you for your question. Yes, this would be the correct key for your engine. Woodruff keys are used on shafts that are 2-1/2 inches in diameter. The square key is used on shafts with a 1 inch diameter. If you need help placing an order for the keys, customer service is open 7 days a week and anyone will be happy to assist you. Please feel free to give us a call. We look forward to hearing from you!

  • First repair attempt...worked like a charm!
    Not a fan of USPS delivery. Part arrived a day late, however, once installed after watching a few online videos my tractor started right up! Bought a spare, just in case!
