Jcb loadall

[Jigsaw G]

Hi can anyone help I’ve got a Jcb 1994 loadall 530-120 and only one of the stabilising legs is now working, has anyone any ideas what the fault is, we have checked fuses and hydraulic oil, many thanks

Is there a solenoid valve on the line that locks it off when the boom is above a certain height? Maybe an issue with that

or a solenoid valve per leg, one of which has bitten the dust
if it were a boom height issue I'd expect both legs to be non-functional

Could also be a relay between your button or switch & solenoid.

Mechanical limit valves on a machine that age. Plunger operated job, as electric wasn't common on that age of machine. I'd bet one of the plungers is stuck. A tap on valve and some lubrication job should be a good'en. One for each leg, hence the fact one is still operational.

Here is a picture showing valve location. I’d start there make sure the oil is being allowed through the valve.

Exactly this they are located near the boom hinge point behind the cab. Sometimes the little roller bearing breaks causing this.
