HI,
I took off my flywheel and sure enough the key was sheared. So I replaced it today, but the engine still will not turn over. It's a 12 year old 18.5 HP mower.
Did I not line something else up?
Help would be appreciated.
Thanks.
This probably does not apply to your motor but I think it is still worth mentioning. One time I had a Huffy Riding mower with a 8hp motor.(?) The blade attached directly to the motor. It had a chain gear PTO on it that drove a gear box with a forward and reverse lever. The gearbox sat out on the deck it's own, fully self contained and impressive looking for sure. It looked like heavy duty industrial equipment. That mower would cut anything, small trees included. It was like riding a little bush hog. Anyway one time I broke the shear pin and after replacing it, it would not start.
I talked to a man in a mower shop and he said "Was there a thick washer on the flywheel" and I said "Yes" and he said "Did you put it back on" and I said "I think I did, maybe. I think there were two washers. I know I put one on and the nut is tight." and he told me to go home and find that big washer and put it on, and the motor will start. So that's what I did, and he was right.
I still do not see what difference that washer made. I had a washer on the flywheel and the nut was tight so I do not see how that worked. But the repairman told me "Without that washer the motor will not start" and he was sure about that being the problem, which apparently it was.
