Cat 60 loses oil pressure

check the oil pump screen first then check the lines to see if they have broke lose also the roll pin in the gear by the cam

If all the above doesn't work warm up the engine and remove the side covers and spark plugs.Crank the engine over and check for oil loss at the main bearings. Some the babbitt cracks into several pieces and allows oil to escape. This will take two people on a 60, good luck.

I’m finally getting into this project. So far I’ve found the front and rear 90deg. Fitting loose on the main caps and one elbow loose in the block above the oil pump. I’ve noticed the treads look as if they’ve been burred with a punch or chisel at one time. Before I try to tighten the main caps I can’t remember if they will screw all the way into the Babbitt and crack it? Naturally the angle I need it it won’t tighten all the way around one more turn to be tight. Any tips? Should I just try some thread locker?
I’m this far into it I’m going to go ahead and drop the oil pump and look into it also.
