Re: Documenting My Crank Walk - Jeep 4.0

Since the bearings are marked 2-97, it is abundantly apparent this engine has been rebuilt at some point in the past.. and apparently, poorly.

I'll bet they didn't check the crankshaft end play, set it up too tight. It wore in, and the wear metals set up an accelerated wear throughout the system, but especially there.

Block and journals most definitely bear a complete, and close, inspection. Someone made a good point about good used pulls being cheap, but even then it's a bit of a crapshoot. That said, I will be doing the same in my 90, shortly.
