    763 hydrostatic rebuild

    Here's the final report on this. Thanks to all who looked and added to the discussion. We resealed the drive motor that had a leak where the shaft fits. That did not fix it. It still leaked too much fluid. I followed that by disassembling again. Prepping all mating surfaces using 220 grit...

    Case drain on 763

    Does anyone know what would be acceptable case drain on a 763 drive motor. This is related to a thread where we have inspected and resealed the hydrostatic pumps and both drive motors. One of the drive motors failed during use when the clamping bolts came loose (not sure if we used loctite)...

    763 hydrostatic rebuild

    Here's some great news on this machine. We pulled the motor/pump assembly and both drive motors. We disassembled the the hydrostatic pumps and they look very good. The information I found said to look for deep scratches in the wear plates and pistons. We didn't see or feel anything that...

    Bobcat 863 high oil consumption question

    It's finally back together. We've had it started and running and good compression on all four cylinders 420 psi +/- 5 psi. Using bolts on the two damaged cylinders. It does make it hard to start so we've added a small magnetic block heater in an attempt to get it to spin the motor faster...

    Bobcat 863 high oil consumption question

    Will follow up when it's back together and report how it's going. Again, I really appreciate you guys who take time to help us. We just wouldn't have the money to run it through a shop.

    Bobcat 863 high oil consumption question

    I attempted to do a compression test and broke off two glow plugs when trying to remove. In the process of removing them we lost one of the electrodes down into the cylinder and had to pull the head. Pulled the head and found a blown head gasket. See pictures. I though Duetz used 3 layer...

    Relays on bobcat 763 high flow

    Sure that can be the problem. Are your relays labeled? They were from the factory but may be hard to read. Just swap one of the relays for the starter relay and give that a try.

    Bobcat 863 high oil consumption question

    Broke two glow plugs during removal to compression test. The two cylinders we could do both have 425 psi +. We are deciding if we try to drill and tap ourselves or just pull the head and take to machine shop. I hate pulling the head without completing the compression or leak down test. argggggg

    Bobcat 863 high oil consumption question

    The original owner is a friend of mine. After talking with him I don't think he used ether to start it. He kept the battery charged, oil changed etc. It mostly sat for long periods of time. We haven't attempted to free up the rings other than running it hard for short periods. Still no...

    Bobcat 863 high oil consumption question

    Update! We changed out the turbo. I don't think it was bad. Lots of carbon on the exhaust side but clean on the intake side and no play in the turbo wheel. Ran it one hour afterwards and still the same issue. It used about one gallon of oil. There is oil blowing out of the dipstick and we...
