Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
It’s air power .you probably have an air leak after the priority valve behind the trans on the frame t cross tube or the valve is stuck . This will also cause the 4 wheel drive switch not to do anything also . The electric is only for indicator lights .
Is the valve in the photo the one you are talking about? I tapped on it, but no joy. I sprayed soapy water all over the air lines that I could get to and didn't see any leaks. Also, with the engine running and the air at full pressure and the clutch depressed all the way to the floor, when I move the collar on the shifter up and down, I can hear a 2-second hiss of air, which to me means the collar is sending signals to the air shift valve/solenoid valve. I need to go through the troubleshooting procedures in the TM, but getting to those pneumatic connections will be a bear.
That is the valve . You need a decent amount of air to flow to make it work . If your axles are dumping too much are the controls for the split shift and 4/4 won’t operate . Try it in 2 wheel drive and see if that helps . If not pull the small line off the passenger side of the valve when your tanks are full . Should get a steady stream of air . If you don’t you can crack the adjustment nut and move the screw back and forth and see if it starts working . Be sure and set it back to where it started . Valve is probably stuck and filled with poo.
I took the line loose and air comes out under pressure. I had a difficult time getting the line off once I loosened the nut. I hooked the line back up. Unfortunately, I hit my elbow on the hot muffler!
The actuator for the splitter is in the top of the case that sites between the bell

2 air lines go to the actuator and it just moves a fork . You can access this by pulling the plate around the shifter . The unit can lift off without tilting the cab
Where did you find a slave Cylinder? How did you access it? I am taking the Loader off tomorrow to make access easier.I just changed my slave cylinder and clutch master . Did not tilt the cab. Took longer to bleed than replace the parts . Now I have chicken arms so that helps
I finally got around to pulling the plate from around the shifter. It was actually much easier than I imagined. However, other projects have gotten in the way of troubleshooting further, but I hope to get back to it this weekend. I do plan on using some soapy water to further check for air leaks in the tubing tomorrow now that I can access everything easily, anything else will have to wait. I feel sorry for anyone that read and believed the TM and ended up tilting the cab when it isn't that difficult to pull that plate.
Thanks for the info. I have a new one from Expedition Imports. Now where is the darn thing on the FLU 419 I have traced the line to no avail.
It’s under the drivers side on the trans . Be careful not to drop the nut plates on the back of the bolts . I forget what the clearance was supposed to be . It’s in the manual . To litle and you burn your clutch and too much it won’t release . It is almost impossible to bleed without a pressure setup .
Just to the right of the trailer brake air aviator is the actuator for the splitter . Air line on the left side and one on the top at the lower side of pic . The sensor in the top is for the display to let you know where it’s at . The sensor screw out . From where you are at you can pretty easily unbolt the entire top plate and lift the actuator and shift for asy out the top to inspect .
Thank you Sir. I changed the master cylinder and it works. After I drive it I will see if I have to change the slave cylinder. I was thinking of taking the left front tire and fender off to gain access to the Slave cylinder.
