Re: Balancing individual steel flywheels
Sorry to say so but that taper is a real mess I wouldn't re use the main shaft either and unless you are careful the shaft will go further into the taper and the nut will bottom on the thread.. BIG angst. Nev

Re: Balancing individual steel flywheels
I am with Nev on that one. The mainshaft should be easy enough to replace but the flywheel will be a problem, whether finding a replacement or sorting out the current one.

Re: Balancing individual steel flywheels
You did see where I was able to get the runout down to 0.004" at the flywheel edge? Is that too much? That is with the nut at about 120ft/lbs. 0.004" is equivalent to the timing side wheel and approximately the roughness of the flywheel edge and the precision of my current fixture. The shaft is not quite bottomed in the taper. Thanks!

Re: Balancing individual steel flywheels
Mauled up tapers do not wear evenly. and will often settle to a worse position in use which will cause strain on the cases and vibration as well as timing gear whine. Unless you're racing it the iron wheels will be fine cheaper and easier to get. The crankpin in them is tapered and the rod eye bush a different size.. Nev.
