Let's not chase him away

As stated STOP messing withe the control valve. The other circuits have nothing to do with the swing function. The only commonality is that the return from all circuits to tank merges before leaving the valve. Everything you need to diagnose this issue is in the schematic that @whitetiger posted...

First off stop disassembling the control valve and do not swap spools, they are usually different for different functions. There is also very little that can go wrong with a spool. But to clear up your reply. You say no change when you swapped hoses/cylinders with the swing spool correct? So...

If another function works on the swing spool when swapped you do not have a valve problem. Your post is a bit confusing but I believe that is what you stated in your post. To me it sound smore like you have the crossover hose between cylinders incorrect. The barrel end of each cylinder must...

OK don't listen

Measure voltage drop using the method I describe not ohms with your multimeter. This is a much easier and accurate test.

After rereading my post I wanted to make myself more clear. By testing I am saying testing of the ign. switch. So test from batt terminal on the switch to the glow plugs terminals on the switch. Also the circuit has to be complete and loaded when performing a voltage drop test

As @NIW asked what is the voltage with the ign. sw. in the crank position? The glow plug circuit goes through the glow plug in the preheat position so the voltage and current will be limited during preheat. During cranking the circuit goes directly to the glow plugs so you will get battery...

I have already read the entire thread. Here is the cover of the WSM manual. The poppet you reference is from the exact same location on the HST housing as the one I posted. The image I posted is from the disassembly/assembly section. From experience parts and service manual diagrams can vary...

I did not direct him to remove the high pressure reliefs. I asked if he had removed the charge relief and not the high pressure reliefs. I am looking at the BX1870 WSM posted on the Kubotabooks site.

You did remove the charge relief and inspect as seen in yellow below and not the high pressure relief/check valves in red correct? You can leave the poppet, spring and shims out temporarily as a test. That should direct all charge flow back to the sump unless there is blockage downstream to the...

Is the filter separating the canister from the base and leaking at the seam or is it deforming the base and leaking at the gasket? If at the gasket is it possible that the threaded insert has been damaged and the filter gasket is not square with the base as has been mentioned? If the filter is...

Anything put into the sump would have to go through the strainer, the hyd. pump, the priority valve, the steering controller, the filter and then into the HST to the charge relief.

One question. Does the filter blow out when just starting and idling the machine. or when you increase engine speed or when you move the machine and if that which direction?

Possibly swap the wheels left for right. Although extending the wheels on the front axle does put added stress on the axle and steering components.
