New bearings, difficult to rotate the crankshaft.

My son got one rod cap on 180 degrees and boy was it tight. All good stuff here. When you tighten the cap nuts have two feeler gauges at the parting line pushing the two rods apart and tight to the crank. This will help to keep them square as you tighten as that wrench turning force can misalign the cap and rod.

Excellent info on the feeler gauges.
