i will try one more time. I have rebuilt this engine twice. First time would not pick up prime and i contacted a man who worked on these tractors all the time. he had taken a remote oil filter and put in an air fitting. Then you put oil in the canister and connect it to the brass fitting on the side of the block where the oil feeds the oil pressure gauge. after removing the line to the filter from the brass block, you connect the line from the canister to the brass block and force oil backwards into the engine. this primes the pump and problem solved. i only needed to do this once and even after an oil change it would pick up prime. unfortunately i had already ruined the crank and bearings. Jump ahead to this recent rebuild and again the pump, even packed with assembly lube would not pick up prime. I made my own contraption to force oil into the engine and viola! 10 pounds on the starter. I only ran it a few seconds, as i have to go to a party. tomorrow i will top off radiator and set timing. The question remains why will this engine not pick up prime by itself? Also you do not need to line bore the engine for a new oil pump, only ream the new bushing.
