Not sure if any of you are familiar with skid steer hydraulics but figured I would ask. I just bought a case 1996 1840 uni-loader the hydraulics do not work to run the bucket and lift. It does run and steer correct. It does have a high flow set up which I got working it will bog the motor down when engaged. I have changed the oil and filter. the holding tank and lines all get hot after running for awhile all lines except the ones going to the cylinders. It also has aux lines on one side then 2 bigger lines on the other side along with a smaller third line. Any ideals on what they are for?

Major parts to test are pump, valve block, and hoses. If you aren't puking oil check the oil level then look for leaks as it operates. Do the valves have cables to operate them? Can you see the valve moving when you move the stick? Try loosening the lift cylinder fittings. Will they squirt under pressure? There are lots of easy things left to test. I'm not a skidsteer guy but all hydraulic systems have fluid, tank, valve, actuator, and pump that you could test.

I have the same machine, the bucket/lift hydraulics will not operate unless the safety bar is down. Check the linkage for the bar. I will look in the manual and see if there is a trouble shooting guide.

The bar is released. I need a hand to see if the linkage moves at the control. I have a gauge coming and there is a tee on the outlet of the pump. Would anyone know what connections I would need to connect to it? The gauge is 1'2" npt. I also read that you should put the tank in a vacum to prevent oil from leaking out when disconnecting hoses, I have a vacum pump but cannot find the cap they make that has a hose connection on it.

make sure the aux. peddle is in the "off" position

The large line with the, single small line is for the high flow. Mine is just the standard flow with lines on the left, controlled by the pedal in the middle.
I just have an operators manual, not much help.
One important service is changing oil in the chain cases. They tend to get water in there, I drained 2 pans of milky fluid from mine, only calls for 6 qts of 10W30 for each side. My dealer said to change it annually.

You could put the gage in the tee after the pump.
I believe the loader valve is under your front floor board, You could mount the gage in a tee at the IN port of the loader valve.
I have a Case 1845c and the maintenance manuals. Don't know how similar the two units are.

Yes really hard to get too I need two people just to see if the linkage moves. I really don't want to go there unless I have too.
