Especially if you are already moving then slow down, as the RPMs drop...

    Bio Hydraulic oil.

    Is there a way to identify(determine) if machine has bio oil vs mineral(regular) hydraulic oil. What leads us to question the oil is that after some oil leaks out on the floor it seems to dry up by the following day. I have run into this on a few machines. In particular today is with a JCB...

    How would you remove these bushings? Komatsu pc35mr

    I have done all the above but which is best depends on your torch skills, You can cut all the way down through the bushing and not cut the bore but even if you nicked it, it really doesnt hurt anything. I lean towards the welding 4-6 hot passes with a stick welder, throw a bolt or some piece of...

    VOLVO EW180B engine not starting

    I can confirm that there is some errors/discrepancy in Prosis concerning cam and crank sensors. I have found that the data is mostly correct however they reverse sensor location with the pictures. In another words they typically show the cam and crank sensors in opposite positions but all the...

    I had one of these exact machines one time that would not start unless I unplugged the VECU, I cant remember if it was shorting/corrupting the data lines or it needs an OK signal from the VECU to start however it would start with it unplugged, ended up replacing VECU. have you tried starting it...

    WA120 Dash?? and serial?

    D3G LGP right track drives, left does not.

    On the surface I would say something broke in the final as if it was hydraulic or control issue it would not free roll, pull the plug on the final and check for metal.

    Komatsu WA200-5

    All later Komatsu loaders are hydrastat, not sure what dash they started but definitely -5 up are. Powershift is just Komatsu's name for their hydrastat trans which uses a variable piston pump and a 2 speed Motor-or variable speed motor, I cant recall for sure and is controlled by a controller(ECM)
