Hydraulic Pump

That might be one of the relief valves. There are usually more before that but I'm not familiar with the hydraulic diagram of your tractor.

I don’t know if that relief valve needs more or less shims to adjust the pressure. But if it is the shim style you will need to add or subtract shims to change the pressure.

Something like this......

None before this valve as far as I know. When I follow the line that leaves the pump it comes straight to this unit in the back. From there it goes to the loader controls.

looks like the line circled in Blue connects to a low pressure hose held on with a hose clamp. If that is true then that is the tank line from that valve assembly.

Well, I'm biting the bullet on this one and taking it to a heavy machinery shop that is within driving distance with the tractor. I am not that confident with messing with the hydraulics and I can't keep the tractor in my shop for an extended period of time either to try and learn my way through it. It isn't all that cheap (110 an hour) but right now I would rather have full use of my hydraulics sooner rather than later and the benefit will outweigh the cost of the repair (hopefully). I'll update on what they find etc etc.

Might want to call ahead and make sure the repair shop has a flow/test meter setup to properly diagnose your system. Without the proper gauges it will be a guessing game and with the right flow meter they will be able to tell in minutes if and what your pump is putting out for gpm at rated pressures.

They are a pretty decent size heavy equipment repair shop. I would believe they have a flow meter but I will mention it when I drop it off on Monday. It'll take me about 20 mins to drive the there with the tractor which isn't all that bad. Repair Services | Lacey Heavy Equipment Repair | Western New York

Thx for the update

So I got an update on this. The repair is saying the pump is no good. They did the pressure test on the line directly from the pump and were only getting readings of max 2400psi at full rpm and then would lose pressure. They then did a flow test on the pump and it failed. $210 for the diagnostic testing. He had 3.16 hours logged but knocked it down to 2 hours which is probably the actually work time they put in on it.

So far so good. I ordered the parts for them since they do a % increase if they order. So my total for parts is $654 (should be there next week sometime). He estimates 3 - 5 hours to replace and 5 hours being if a lot goes wrong. If that stars align and everything is perfect, I may have my tractor by end of the day next Friday. Reality, I'll probably be picking it up sometime the week of the 16th.

I did, however, ask about swapping my loader control valve for one with a 3 third function. He had something coming in today for an excavator that is new to him that he is trying out. Supposedly its a 3rd function control and only cost $295 (part only). He was going to let me know how it worked out for him and if it was something we could do for the tractor. I would like the 3rd function to be at the joystick instead of behind me and to the right.

It will be interesting to see what he is quoting at nearly $300. Typically folks get an electric over hydraulic valve and then put a switch on the joystick. Some switches are built into the a new joystick handle.
