    Komatsu PC75 UU-2 I threw Track , Adjuster is stuck solid.

    My tack adjuster is different than shown. I have the parts manual. The yoke is free, the Piston is stuck, especially as I beat the yoke in with a sledge hammer to get the track on. I used a hydraulic jack and a 16# sledge hammer to drive it back. Track is back on but grease gun will not expand...

    kamatsu pc75uu2 excavator 1997

    PC75 Does not have the strongest tractive force, but it still can do a bit of dozing, I think swing force is quite weak for its size and the dipper extend force is not real strong. My pressures are ok. I think the offset boom design caused Komatsu to keep swing force limited to save the...

    pc75uu-2 steel tracks coming off

    That's the victory photo of just getting the track back on the idler. Have you ever tried to get the track back on without dumping the grease out of the tensioner? I lost the track messing in the woods and limped it out to a spot I could work on it. Used the machine to pick itself up...

    pc75uu-2 steel tracks coming off

    Have fun, It took a lot to throw a track on mine. Agree that you need to find out what up with the UC. I have a 6000 hr Worn UC and it still takes a lot to toss a track.

    Komatsu excavator to buy

    If the offset Z boom was a weak design, I'd have broken it long ago. My PC75UU runs hot, not to the point of having to stop it to let it cool, as I just slow down a bit and let the cooler bring down the oil temp in summer.

    Komatsu excavator to buy

    Pc75 I think the dipper curl force on the PC75UU2 is weaker than a simialr size Std boom. The PC75 also came with a dipper extension option like a backhoe. I disconnected my potentiometers. I have steel tracks. Finally tossed a track after owning +5 years. Fun, Not so much.

    komatsu pc600 lc electrical nightmare

    I have the same issue on a slightly small machine, a PC75UU2. I have a switch wired around this to allow starting when the diode acts up. I have no Idea how to find diode in harness or even access the alternator.

    PC 75 uu-2 help...

    If you did what I think you did, you must have bunged up the machine badly. Luck you did not short out the front battery. It must look ugly. You can buy fittings from Komatsu. How bad did you mess up the sheet metal and plastic covers? Take it easy guy! I bashed up mine, but hammered the...
