Hi Stan. I just removed the oil filter assembly and only a trickle of oil came out while a short running of the motor.

I took out the oil pump it looks ok. The gears have a wee bit of slop and the end cover is smooth, no gouges.

The oil pressure gauge is on the filter housing.

In the process of draining the hydraulic oil and replacing it.

Any thoughts on the low oil pressure? Bad oil pump ? Bypass open in the oil filter housing ? Broken oil pump gear ?

Yes, white color of fluid, but seems to be cool to the touch.

I have a 420c with smoke coming out of the hydraulic tank. The hydraulics work fine and have 800 psi on piston lockup. I also have 1 to 2 psi on the new 0 to 30 psi oil pressure gauge. Thanks
