I'd bet a hamburger that you're going to wind up replacing the hydraulic pump.
Well this isn't fishing related but I thought some of you guys/gals might be able to help me out on here. I have an Allis Chalmers 5015 diesel tractor that I can't get the back arms to pick anything up. Will go down but won't pick up any weight. We have drained the hydraulics twice, the 1st time it was milky and we have changed the hyd. filter twice. Also my brother found a couple of small pieces of plastic in the fluid when we drained it. Anyone have any ideas? Thanks in advance.

Does it have a strainer in the sump?
Not sure how the hydraulic pump is set up on this particular tractor, but I have seen a tractor sheer a key that spun the pump shaft, took us forever to figure it out. put another key in it and started working again.
Do what Doyle did. Google search that pump, then see if you can’t find a diagram for the system. That should give you a breakdown on parts plus an idea where that plastic looking stuff could have come from. I suspect pump seals have come apart plus some of it could be stuck in bypass valve. Shouldn’t be to hard to rebuild once you see a drawing and what parts you need.
