Oil Pump shaft broke

This happened to me March 2022. Shaft broke off in the oil pump. Found the oil pump sized up. Took the pump apart no debris at all. Found the specs for the pump and checked with feeler gages. one spot was too tight. Got a hv pump, harden shaft, and also replaced the bushing for the shaft. Found the bushing was worn and that’s what was wobbling the shaft and put pressure on the pump (so I’m guessing). Got the special tool to seat it in, put everything new in it. Primed it, started it and also noticed my timing wasn’t jumping anymore.
