Case Skidsteer

[eboyce]

All the linkage is under the seat the valve is behind the seat in the engine compartment. It is a ***** to get too especially with all the extra hoses.

Ha Ha ha, welcome to the world of working on skid loaders. If you think that's bad, there's a lot worse jobs on that machine. I've got one, and have had 3 of them.

Skidsteer is working now, Some one along the way cut the lines going into the loader valve and bypassed it to run the auxillary only! It has been that way for a long time cause the line that used to feed the aux from the laoder valve was under 2' of oil and dirt.

Problem is now I do have enough pressure to pick up a bucket load of dirt. I have hooked a gauge into the auxillary connection and when I engage the aux I only get 825 lbs. The pump is new I took it in and they said it worn pretty bad and it showed. Any thoughts adj the unloader relief setting? Not sure if it is adjustable.

If the pump is new, how can it be worn that much.

The pressure you obtained, is that when you fully extended or retracted the cyl?

The pressure developed by a cyl would be dictated by the type load.

Could be bad piston seals in the cyl.

Most loader valves are adjustable. Some use shims and others have a screw to adjust.

The pump is new the old one was worn.The pressure was taken at the auxiliary connection with just the gage connected.

You really need a flow meter and pressure test, where you put a load on the pump.

 

[Arc weld]

Open center hyd's only put out the pressure required to do the job. You basically have to dead end a circuit to see how much pressure is available.

So now the new pump is already bad burned up overheated. Any know where I can get a used one?

 

[Larry car]

I fix elevators for a living and not claiming to know your fix but motor bogging down and oil heating up is a sure sign of valve not opening.1 of the replies said that the valves may open with cables I also own a 1840 and his reply sounds dead on.

You need to make sure you have the correct valve in the circuit.

In an ope center hyd system, the pump is pumping all the time the engine is running, and the flow passes through all valves if the lever is in neutral.

You can damage the motor with pollutants, but to burn one up with fluid in it, you would notice the sound and the smell and the color of the fluid.

Apparently, there is a blockage caused by a bad relief valve or bad hoses, or wrong valve type.

When you installed the new pump, did you check all the other hyd components?

Did you have correct flow through the valve,and did you do a pressure check .

Since you said someone cut some lines, you have to wonder if they even knew what they were doing.

You may have a lot of jury rigging in the machine now.

I would suggest a good workshop manual before you waste any more money.
