    Controller schematics

    Hi Samuel, Before replacing a controller, I would look at the bypass switch. When they fail you get no power to the controller. Hope this helps.

    Case 1085C Excavator

    There is a spring applied/hydraulic release brake pot (hydraulic maxi pot) on the input to the rear axle. I would look there first. There is a caging bolt, you can manually release.

    Doosan 250-3 Regen

    The WIF sensor is in the fuel separator bowl, primary filter, R/H side of the engine. The machine will regen while working, as long as the temps are up.

    Doosan 250-3 Regen

    LOL! I know what you mean Got a little trick to help you out... as long as the machine has been working up till now, there is a differential pressure sensor at the DPF. Sensor has 2 hoses running to it. Fixed more than a few. Sometimes carbon will block 1 hose, false reading, ECU will signal a...

    Doosan 250-3 Regen

    Hi Tony, Did a dive into your codes, the 2 I would worry about is a 'EGR timeout' (likely a loose or corroded connector) and a 'metering unit' low pressure (could be some trash in a filter head, HC injector or the metering unit) Once you have the codes solved we can run thru the procedures to...

    Doosan 250-3 Regen

    Hi Tony, There is a lot to unpack there. First, solve the water in fuel sensor problem. Second, install a new thermostat (advise to get one for a -5 machine) Both will inhibit regen. As for the history codes, can your laptop monitor the fuel pressure at the metering unit, egr position and...

    Doosan 250-3 Regen

    Hi Tony. The pilot disable (hydraulic lock) switch is in the right side switch panel, should be the first one of the inside line of switches. Try the switch, if you have no hydraulics, good to go! As for the park brake, most -3 machines have a starter interloc from the factory, should not...

    TL240 quick attach hydraulics not working

    I have seen a few Tackeuchi's have a failed micro switch or actuator plate at the auxillary hookups. When you have aux lines hooked up, they push on a plate, closing a micro switch, allowing flow to the coupler and auxillary circuits. Hope this helps

    Doosan 250-3 Regen

    If that is a Doosan DL250-3, make sure the machine is at least at 170F, the park brake enabled, hydraulics disabled, and the machine is around 800RPM (low idle) before you press and hold the regen switch for around 8 seconds then release. It should idle up within 2-8 seconds. Don't touch...

    Case 1085C Excavator

    Hi Dan, you are on the right track! First thing, check fuses. The problem is most likely the electrical swivel, that is between the hoist base and hoist cylinder. Remove the cover and you will likely find corrosion. Have had good luck getting them going with lots of contact cleaner and air...

    Hein Werner C12 HD Excavator

    Hi Mission Man, Just back in action, sorry I didn't get back sooner. That is a pretty sweet machine you have there. As long as the function of the hoist and stick seem fine, should drag the machine on the ground with stick only and lift the side with hoist only (good lifting power/speed)...

    Doosan DX140 LC-7

    Hi ponch458, just had coffee with another field mechanic who's older than me (like, 1 foot in the grave) he reminded me that Doosan has boom priority hydraulics, if your operator is not used to it, could be some of your problems. I will look for a way to mitigate/change that. Remembered on a...
