Here's the story!

kxpegger:
I posted about this a while back. The water pump spur gear broke off the crankshaft. I thought that the crank could be repaired by just replacing the spur gear. In addition to the spur gear being broke off I discovered the main bearing was shot on the same side and it really did some damage to the crank. By the time I would have sent the crank off for repair it was about the same costs as buying a new one! I'm convinced that the bad main bearing is what caused the spur gear to break off. Collateral damage was some scoring on the cylinder and piston from overheating. I had a spare new piston and cylinder and bought a new crank. All this because of a bad bearing! Engine had probably less than 120 hours on it





The engine is rebuilt now and back in the frame! Thought I'd go through the rear chassis and found some problems there too but have been fixed. Still waiting on a few parts. Can't wait to get the beast running again and thinking about maybe showing up for the next Kalifornia run!
