Default Re: Tight Bearings

The center main usually has more wear than the front and ream mains. Adjusting all three to the same clearance on a used motor can result in tightness in the center main if that journal has runout. I prefer to run a dial guage on the center crank journal to see if it is running true, then adjust the center main last.
