    John Deere 444J can monitor unit

    For an old retired guy I can sure stay busy trying to keep my ranch tractors running! I rent my 444J out in the winter to a snowplowing company so this last year it got a good workout. The latest problem now is the dash display. It goes thru the test cycle fine but then the gauges just stay in...

    JD 444J head bolt torque specs

    I’ve had to replace the head gasket on my 444j and wanted to know the torque specs. I’ve found a few specs on google but just wanted to check here. Does it require oil on the bolts or dry? Any other tips would be appreciated. The machine is low hours so I’m not sure why it failed but it didn’t...

    310SG vibration

    Plowing snow my 310SG developed a vibration in the hydraulic system. It vibrates when operating any hydraulic function. It feels like a sticky ram packing but it happens with all functions front and rear. Oil level is good and everything is greased. I’m suspicious it is the pump going bad...

    John Deere 210le won’t drive

    My 210LE decided to quit driving. It quit driving the other day and after a few minutes started to drive again, a few days later it stoped driving and no amount of shifting or jiggling made a difference. When you shift forward to reverse the drive shaft moves but will not move the machine...

    John Deere 450H

    My 450H is starting to lock up the right side track. It is intermittent and if I raise the tracks off the ground and run the right track back and forth it will work fine. I think it might be the revolution counter on the hydrostatic motor but wanted to see if anyone else has had the problem...

    Peterbilt 335 Allison transmission

    My 09 335 with a 6 speed Allison transmission won’t shift into gear. Parked the truck and it worked fine, a few days later went to drive it, pressed the brake pedal, pushed the drive button and nothing. When you turn the engine off and with the key on I can push the key pad and it displays the...

    JD 444j electrical problem

    My 444J has an error code of 100.4. This code is engine oil pressure open or short. The dashboard gauge module shows no movement on the oil pressure gauge or any of the other gauges after the initial check mode when the key is turned on. All gauges move to the right stops and the red lights...

    John Deere f9c4 code

    I have a JD 310sg that is showing a f9c4 code. The tractor starts and runs fine. I put die electric grease on the connection at the controller and inspected the harness under the machine and dash, nothing looked out of place. I know these are very hard to diagnose but was wondering can the...

    John Deere 444j monitor

    The oil pressure and transmission temp gauges peg right after I start the loader. They return to zero when the key is off. The idiot light doesn’t come on. The monitor part #AT355016. I was wondering if anyone has tried to open up the monitor and repair individual gauges or if there is...

    Hitachi technical manual

    I'm looking for the technical manuals for a Hitachi EX135UR-5 or at least the wiring diagram. I tried Canadian dealers and UK but no help there. If someone knows a source in Japan or elsewhere I would appreciate it. This is a gray market machine and John Deere won't support it.

    I have a 2002 hitachi ex135ur-5 that won't throttle up. Worked fine then sat for a couple weeks and the problem started. The key will start the machine but has no effect from the on. It will only idle and they key will not shut it off. I have to use the manual emergency stop cable. I have...

    EX 135ur-5 throttle problem

    I am trying to set the throttle position on an ex135 ur-5 but I can't seem to get it to remember the correct setting. I've tried to hold the toggle switch down behind the seat and turn the key on with the throttle set at idle, let the stepper motor cycle the turn off the key, this may not be...
