Crankshaft Nut

recon · Jul 17, 2006

I have lost the nut that holds the fanbelt pulley on the front of my 2200. It looks from the parts manuals to screw onto the end of the crankshaft. I can slide the pulley on the shaft and it will run for a while but eventually spins itself off. I ordered an M30 nut from Hoye but it did not fit (too large) The diameter seems to be somewhere between 7/8 and one inch on the threads of the shaft. Any help would be greatly appreciated since it is rough trying to mow 5 acres without my tractor. Thanks

One inch in metric is 25.4 millimeters. That would be the best I can help you with trying to figure size. Hoye or one of the other dealers on here should be more helpful. If you have a metric socket set that could help with figuring out the inside diameter you need.

You need to measure the thread diameter in mm's and go to a specialty nut and bolt distributor or order from a place like McMaster-Carr, probably 24mm, 2 pitch, get 1 of each pitch.

I have several YM2200 parts tractor's with the nut on them.
