    Default ML30 Loader MT275 Challenger tractor increase loader power

    How do I or can I increase the power in my hydraulics. I understand (and I know its not on all tractors and I'm not sure if mine is one of them) but I hear there is an adjuster screw to in crease hydraulic pressure. Which I know I'll get a pressure gauge and find out what the max pressure is and set it up to the max pressure. Thanks

    If you know the pumps rated pressure, you can install a hyd gage and check and set the hyd pressure. It should be about 50 to 100 below the pump max pressure.

    You can install a gage permanently in the IN port of the FEL valve, or use the plug in test hyd gages kits.

    You can also plug the gage into a QD and momentary flip the lever to get a reading and or to set the pressure.

    Here are some examples of a hyd gage test kits.

    Larger hyd cyl will also provide more power.

    I like the installing the gauge. How and where do you install it? Does any one have any pics of theirs installed?

    How do I increase it once I get the gauge installed?

    You either turn a screw on the relief valve or add shims to the relief valve. Look at the parts for your valve and determine what you have and go from there. If it is adjustable, install the gage and adjust. If you have to add shims, take the model number of the valve, or part numbers and purchase the shims at your dealer

    If you want to install the gage, then you add a tee to the IN port of the FEL valve and add a 3000 psi gage in the tee. Then you can monitor and trouble shoot the hyd system.

    It will show the hyd pressure for any operation you are doing.
