Fired the parts cannon

Parts cannon fired back.

 

New crank, bearings, etc. Tq to spec 80ftlb, in tq order. Harmonic balancer bolt over-torques before crank will spin. ( no pistons or anything else on yet )

 

Plastiguage set at 0.003 all the way down the crank. 

 

Stumped.

Thoughts? 

Help...?

I don't have much experience with engine building. However it would help to find out which bearing(s) is causing the issue. Loosen all the caps and then torque one cap at a time and check rotation and figure out if it is just one bearing causing the issue or all of them.

EXCELLENT SUGGESTION.

 

BTW, I assume the OP has slathered all the crank journals with assembly lube or, at the least, motor oil.
