Define wiped out. Did you see the bearing and crank? Was there score marks? Did the crank seize? Did you, during the rebuild, have the crank 1. replaced 2. cut and balanced (requires new larger bearings) 3. nothing and put back in. Did you torque the cap bolts to tight? Did the ears break off the bearing? Theres alot of different things that could happen. I rebuilt the 6 in my 79 cj....I didnt notice my the piece of metal shard that had somehow fallin onto the bearing when I torqued the cap on. I should have turned the crank by hand too....stupid me......lets just say it was an expensive mistake, the crank was to far gone to be reground......and I wasted the money on the dam oversize bearings....AHHHH.......Guess thats why I got the new TJ. Lemme know about the crank!
