Marc, you have severe wear on the crank or flywheel splines [or more than likely both].. ~The proper repair is to replace the flywheel & crankshaft.. ~You have one of those problems that a person kind of has to look at to suggest a viable repair.. ~You have to determine if the crank splines are still serviceable.. If so maybe a replacement flywheel will do the trick... ~If the crank splines are just worn a little you might be able to locate a Taper-Lock flywheel for it [I'm not sure they are available for the "B" though].. You might try 2-cylinder plus [417-589-2634],, or Denglers[1-513-423-4000]. ~There are any number of other ways to TRY to repair your problem, from welding the crankshaft & re-cutting the splines, to adding shim stock between the flywheel & crank [that doesn't hold up very good],, to using JB weld [that doesn't hold up for long under load either but will probably hold until you find a real repair] ,, to just welding the flywheel to the crankshaft [that usually holds up for a while but as you can imagine it makes flywheel removal difficult].. I have even seen the flywheel to crankshaft drilled at the joint & hardened pins driven in [that probably has the best chance of holding for a while]. ~If the wear isn't extreme you MIGHT be able to use hardened bolts & nuts in the flywheel & just tighten it more [CAUTION: that could also crack the flywheel].. ~That big nut is for flywheel safety retention & to keep it from migrating on the crank.. It also makes end play adjustment easier... JDClooney@aol.com
