GMT 400 obsessed Swede.
I'm going to get straight to the point: I was installing the crank into my engine I'm rebuilding for my K1500, using new bearings, assembly lube and the main caps in the correct position. I torqued it down to spec in the correct order and it rotated great. No binding or anything. I noticed some imperfections on the counter weights, so I took it out and brought it to the machine shop that did the machining to the block and had them correct the imperfections.
I got it home, installed it in the same way I did the first time; same new bearing since they didn't have any imperfections; lube and caps in same place that they were the first time. Each bearing was re-installed with the original cap when the crank was first installed.
Torqued to spec and now it will not rotate at all, at least not without great effort.
Even the bearings seem in perfect condition and designed very well (King engine bearings).
Did I bend the bearings or crush them just enough that the crank won't rotate by hand when torqued to spec?
The crank rotates freely when bolts are just hand tight and adequate lube on crank and bearings.
Are the bearings just one-time use once torqued down?
