No spacer goes under the flywheel nut. What you just said further verifies it is stretched by using an impact wrench on it.
I appreciate your help. Since it’s done this since I bought it, it must have happened in the past.
Would you recommend putting a washer under the nut?
No, that is not a solution…The problem is like Frank says…At some point, someone over torqued that flywheel nut, perhaps they put it on with a powerful impact gun, which has spread the taper open allowing the flywheel to sit lower on the crankshaft than it should. Pull the flywheel and have a very close look at the hub, perhaps you will see a crack like the one Mumbles posted. I would replace the flywheel. I’m sure you can find a used one for a reasonable price…I will have a look in my pile the next time I’m down cellar…You can have it for the shipping costs if I have one…
Beware, that not all 10hp flywheels are the same, you need one from a 58 and newer 10hp…D
