Cat 3406 Low Oil Pressure
in Engine and Transmission
Posted
Have a 3406B, after about 120k on an inframe had #6 piston failed. Oil pressure hot at 1600 rpm was 55. Took it to a shop, put 6 cylinder kits in , got it back oil pressure was down to 52 at 1600. #1 piston failed.
Took it back they flushed the oil galley new cooling tubes and oil pump. Oil dropped to 45 at 1600. Ran 7 days #4 piston has failed. Anyone have any ideas?
