Has anyone ever had a problem with the drive gear spinning loose on the high pressure oil pump of a HEUI injection system? This is on a 1998 International DT 530E engine. We've replaced the pump (ran about 1/2 hour) Replaced oil pressure regulator valve. Gears loosens & spins bolt out about 1/2 inch. Gears & Idlers look fine though have not taken front cover off. Gear torqued to 95 lbs per specs, fuel press 50 & high press oil max 2500 psi on test gauge at full load, Engine warm but not hot. I can't find anyone that has run into this problem. Have not replaced the ICP sensor. Not sure if this is the best forum for this question, new to these forums. Thanks
