Here’s what I determined after Plasti-gauging the crank in 4 90 deg. increments, torquing all caps in 3 stages (cleaned lightly oiled bolts), in 2,3,1,4 bearing order. I have found that thrust is .003 at bottom of bearing but won’t pass .003 feeler gauge at top of bearing .003 is my thinnest gauge. I removed #3 bearing but crank still turns hard. Obviously, I need more thrust clearance, but is that a matter of more machining off the recess of sanding the thrust collar itself? Also, if I must go back to the crankshaft shop, should I plasti-gauge the rod bearing journals to determine if they have issues, too? Thanks for your input.
