How do you check for phase? I will be installing pipes on the sled, I'am changing the two bearings on the pto side and the one on the mag end. The old bearings still look ok,but since I can get at these I thought I would change to new ones. I also drilled out the oil hole on the pto end to match the others. Any other items that I can due to make the crank hold up longer? Should I advance the oil pump some? I will be using Polaris regular blue oil. The pipes are LRM's. Any help you can give me would be appreciated.--Thanks--Mikemadcow said:you have to check run out on the ends of the crank and center, then check all bearings, check rods for detonation damage and then check the crank for phase.
