    Komatsu PC210NLC-8 intermittent command loss

    Hi all!!! Been trying to catch fault with this machine for few days no but no luck. Machine randomly cuts out all the commands, no boom arm bucket movement, no travel. It just sits there like you raised safety switch. You let all commands in neutral, and 8-10 seconds later, everything is...

    Doosan mega 400 noisy pump

    Hi all, Pump on this loader became very noisy lately. At first only when cold. Then after about a month, when warm also. Hydraulic filter was recently changed, didn't help with the problem. This is the info I got from the owner. I suspected that pump is sucking air, because it sounds like it...

    JCB 2CX steering and brakes problem

    Took the priority valve apart, cleaned it up, and tested again. It charged brakes and steering started working. But after operating working hydraulics, it stopped working again. Like valve gets stuck. But I didn't notice anything unusual when I took it apart. Any ideas? Thanks!!!

    Case CX370C diagnostic ports and options

    Hi all! I need to find out how to connect to this machine with diagnostics. I have CNH diagnostic, but I don't have cabling required. With my cable I can only connect to engine. Apparently to connect to rest of the machine you need Y cable and cable with the box containing 2 switches. Does...

    JCB 2CX steering and brakes problem

    Hi All!!! I have model SLP2CXASTE0760003. It has combined steering priority and brakes charge valve. It has a problem where there is no brake action, and no steering action. Steering only works if one of the working hydraulics commands are activated. I'm guessing this priority valve needs...

    John Deere 690C Losing power and dying out

    Well, that is different problem then. In that case it might be the engine. If your pressure is set properly and it kills the engine on bottoming out then your engine doesn't have enough power. As stated above, fueling is your first point to check.

    John Deere 690C Losing power and dying out

    Well thet is pretty much straight forward. Only thing I'm not sure is how those flow dividers work, never came across them. Is your pump gear pump? Do you have hose burst protection on cylinders? What happens when you close the bucket to the limit and keep command forced?

    John Deere 690C Losing power and dying out

    You said it your self. Engine labours only on out movement. So it can't be the engine!!! Hydraulics are ovepowering it somehow. You need to figure out what is pump doing different on out movement. Maybe post hydraulic schematic here so we can try to figure it out?

    VOLVO EW160C commonrail pressure problem

    Did bit more testing on this machine. I found that when I unpug fuel regulating valve. Mechanical overpressure valve is supposed to keep the pressure around 720 bar. As you can see it happens sometimes, but not always. One photo is when it happens, clearly you can see that rail pressure is aroud...

    Takeuchi TB 135, Solenoid valves. 2007, S/N 135-19406

    If I had a penny every time customers do this when I tell them to swap coils over...... :) You are correct, wiring has to stay in original position, only coils need to be swapped. If they are different connectors, you need to cut them off and recconnect as per you needs.

    PC78US-6 Hydraulic Schematics/Circuit

    Interesting set of problems. I'll just throw out couple of ideas. I don't have intimate knowlege of this machine, so be aware of that. While tracking forward, the boom wont raise up. Does this machine have travel mode switch where it disables commands while traveling? If the blade is raised...

    Fiat Kobelco EX215 engine bogging down on stick operation

    Hi All, Above mentioned machine us bogging down the engine on the stick when pushed to the limit. When under 2/3 throttle, boon and bucket seem to overload the engine also, but not enough to shut it down, even when both combined. But stick pretty much kills it once it reaches the stroke limit...
