The WSM procedure involves a ($$$$) flow meter. You can accomplish the pressure portion using this test rig: Remove the delivery pipe from the pump and connect an adapter plate. Connect the adapter to a tee with gauge in the middle.leg Put a 3000 PSI needle valve on the third leg of the tee...

In the parts diagram pump looks like a 4 bolt flange but whether its standard or not ????? Damn relief valve is $500 !!!! Before poppimg for that I would do a pump discharge test. Do you know how thats done? Dan Dan

Thats encouraging and sounds very much like the relief valve is misbehaving. Three point wont work because your gauge has power beyond blocked. Try that again. Watch the gauge as you turn the adjuster in. Pressure should increase as the screw is advanced. System setting is 2700 PSI. Dan

Pretty sure you got the right relief valve. How did you go about setting the adjustment screw? Ideally the next place to go would be a pump discharge pressure test but thats not an easy test to plumb up on that tractor. Dan

I will second the "well crap". Are you sure you removed the relief valve and not the safety valve? I am also of the same mind as you with regard to the pump. Just to be sure about your inlet pressure test. You removed the hose connected to the IN port and screwed the gauge DIRECTLY onto the end...

If the IN hose is reading 700 PSI something is wrong upstream. That feed is coming straight from the pump and should be roughly 2700 PSI. Given the sudden nature of thr failure my first thought is the main relief is stuck open. Dan

Thats quite clear. Disconnect the hose on the port labeled IN and connect your gauge to the hose. What pressure do you get there? Dan

That was my immediate reaction. What did you remove from that port before installing the swivel fitting? Put things back as they were originally and post some pictures of that. Dan

This type tee and a JIC cap will let you hook in for both tests with minimal changeover.

Contemplating a lung transplant was intimidating but it was not as bad as you might imagine. In fact I experienced very little pain - oxy works as as advertised.. Lost strength and muscle mass is another matter. Working on getting some of the weight and as much of the strength as I can back...

The L4701 is completely different. It has the Grand L style outlet block under the seat wirh three separate ports for pressure out, pressure return, and tank return. You do not have that on the smaller L01s. The first video link you posted is for OEM remotes on the L2501, L3301, and L3901...

Same threads and connection point as the power beyond hose. Probably a female JIC-8 or -10 swivel. Dan

I am sorry - got this thread confused with another so I would like to retract the relief valve comment Finding the problem should be straight forward. Start with pressure tests at the loader valve power beyond port. Remove the power bryond hose and connect the gauge to the power beyond port...

The neutral circuit on ypur tractor is quite simple. Pump -> loader valve -> system relief valve -> remotes -> 3pt. I dont see anyway a stuck relief will give you the symptoms you have. Dan

The port under the seat is just a tank return. The OEM valve stack adapter plate uses it. The pressure return is via the blick under the floorboard. You can DIY dual remotes using a generic aftermarket valve for 1/4 the cost of OEM. Not as pretty as OEM but just as effective. Here's some food...

Just as you described earlier - with issues. Dan

Its a knockoff of the Woodland Mills grinder. I have the Woodland Mills and it works great on my L3901. I dont think I would want one on a smaller tractor. On a good size stump it really bounces the L3901 around. Dan https://woodlandmills.com/wg-24-stump-grinder/

The hydraulic outlet is under the front right floor board. I thought you were planning on a DIY system. Your dealer will offer you a complete OEM remote kit including lever guide. First valve kit about $1000. Second and third valve an adfitional $800 each. You dont need or want a valve for a...

You need the OEM adapter plate for the hydraulic block (60 in the diagram) and the three orings (70). The rest is all standard hydraulic fittings and hose. You also need a comtrol valve with power beyond port for your rear outlets. Connect valve to adapter plate per description in owners...

SA cylinders work fine with SA valves. Problems arise when you skirt the rules and try to use a DA valve to control a SA cylinder. Dan
