My mechanic told me to buy it together with the hydraulic pump. I gave the tractor for service to replace the clutch and all the fluifs. When they changed the hydraulic fluid, they forgot to change the filter, the filter was very clogged, as a result of which this valve broke and the hydraulic pump almost stopped working.

The part has Kayaba written on it in Japanese and a part number 21730-00401 that does not correspond to the Kubota number.The dealer assumes that this is the part 110 in the diagram below.

Are you wanting the priority valve?

If you do, contact @007kubotaguy he might have that valve.

I think yes.Mechanic send me this pic from internet...I gave the Kubota dealer the part number 35270-16710 and he said that my tractor 2wd does not have that part. He also said that my tractor does not have power steering, but my tractor has power steering.

It was an optional add on to that tractor, and yes typically was added to the 4wd version.

Filter is in the side of the trans housing. It is basically just a cylindrical 'Screen'.

You'll need it and the O-ring that goes with it. Some kits include the O-ring.

Priority valves are fairly simple, and not prone to failure.

What issues are you having?

And do you have the tractors serial number?

I'll be near the tractor tomorrow and I'll look at the number, I know where it is. I brought the tractor to replace the clutch, all the hydraulics worked perfectly, the tractor just didn't move. After replacing the clutch, when the tractor was started, three loader hoses immediately burst. I bought new ones and they installed them and started them again, the hydraulics, according to the mechanic, don't work. As he told me, you need to buy a hydraulic pump, a hydraulic filter and this valve. This all happened because they forgot to change the hydraulic filter. The next day, this person quit and has not responded to communication, now another person will finish the repair.

Sounds like the PRV ( Pressure Relief Valve) or a piping/ hose routing issue has an issue not the Priority valve.
If it dead headed it could blow the seal out of the pump, but blow three lines on three loader
would be very odd.

Is the motor filled with hydraulic fluid?
Is the pump cracked or leaking externally?

I need to see how they have the loader hooked up to the tractor.
There should be three hoses to the loader valve and three locations on the tractor.
Wonder if during the split to replace the clutch mutiple lines got swapped.

This tractor does not have the PRV in front of the system like other models it has it on the back end of the system (bad design for safety of the system) so one hose hooked up wrong will cause all sorts of chaos!

The pump works, but it is very worn, according to the mechanic. The pump did not leak or crack. I don’t know anything else. I’ll try to find out something tomorrow.
