cluchbell bareing

make sure its shimmed. if its not ull be going through bearings after every 2nd tank.

Also check for wear on the crankshaft bearing surface, bad bearings can eat away the surface and cause issues with new bearings...
I keep extras in my box, and change them frequently, if they still feel good after changing, i soak the old ones in Mobil 1 motor oil, and keep them
in a sealed container for later reuse. Pay close attention to your gear mesh, you may be overtightening as well....

Thanks for the help

u broke the steel clutch bell or the spur gear? my spur shredded a couple tanks after i fixed my shims but thats cuz when the bearings broke it took chunks out of the spur gear...

I’ve seen it happen a few times with people running a stock clutch bell and hardened steel spur.

A clutch bell bearing that fails often and quickly is usually attributed to the mesh between the bell and spur being too tight.
