The problem typically happens because pressure builds up in the loader hydraulic lines AFTER it has been disconnected. It usually happens when the loader is removed in cool temperatures and then re-attached in warmer temperatures as the fluid expands and creates pressure.

Start the pump and watch for build-up of pressure on the gauge while tightening the relief valve adjustment. If full pressure can be developed, obviously the pump and relief valve are operating correctly and the trouble is further down the line. If full pressure cannot be developed in this test, continue with Step 3. Step 3 - Pump or Relief Valve

The pump, which provides the hydraulic pressure and flow to the motor, is the heart of the hydraulic system. All power take-offs covered by this chapter are available factory installed. Some variants can also be ordered. It is important to design an optimum hydraulic system, and to specify the correct pump size to provide sufficient oil flow and

Mar 12, 2019 · Or you can build your own to check hydraulic pressure. Adding shims to the relief valve ups the hydraulic pressure (which increases lift capacity of your loader) among other things. Many youtube videos and threads on it. You just need to be careful with increasing the pressure too high. Looks like your spec should be between 1790-1850 PSI.

May 02, 2017 · Discussion Starter · #1 · Nov 23, 2011. My LA463 front end loader control valve must have either a stuck spring, or a broken spring. When the control lever is moved to the left, it will not return to neutral by itself----either with hydraulics pressured up or dead. The schematic suggests that it is the upper spring that is stuck in a

May 03, 2020 · It has bascially, two hydraulic systems, and both work from one common sump/tank. System #1 has an engine-driven hydraulic pump that powers the power-steering - or - the swing on the backhoe. It is either-or and you must choose one or the other via a diverter valve with a push-pull knob. Pump is rated a 7 GPM.

Sep 23, 2009 · As long as you have 5 GPM available from the pump the steering and controls will work but you will starve the differential lube circuit and there is no warning light for that. The 5 GPM is sent first to the steering and the return flow (or bypass flow if the steering pressure exceeds the steering relief valve setting) is directed to the MCV
