Purchased a set of coated Clevite bearing. I installed the crank and used the method Ray P. suggests to seat the thrust bearings (tighten girdle then loosen bolts 1/4 turn, tap both ends of crank to seat thrust bearings, retighten). Before installing any pistons/rods I had a last minute change of heart and upgraded to Ninja lightweight rods from stock so I removed crank to get it balanced. Upon removal noticed wear shown in pic on one of the thrust bearings - other 3 are fine. Crank had only been rotated by hand and plenty of assembly lube was used. Rotated smoothly.
I've ordered a new set of thrust bearings, and don't want a repeat. What should I do differently next time?
