    JD 350G Oil dripping out vent tube... again new engine

    Ordered a new vent, seeing we used the old one when we put the new motor in. Field rep had no other ideas of the cause on the old engine. said it was blowby. He checked turbos and a few other things. Said there was nothing else that would cause it. We went with his word. Past history now...

    JD 350G Oil dripping out vent tube... again new engine

    What actually spins inside it? I took that apart before replacing the old engine and cleaned it. Rep said on the old engine it was probably blowby causing the oil to pour out that vent hose. could have probably filled a bucket with oil in twenty minutes on the old motor. He never really...

    JD 350G Oil dripping out vent tube... again new engine

    Last summer we put a new 6090 engine into our 2012 JD350G serial # 1FF350GXTCE808707 because of oil running out of the vent tube. JD field rep said it needed one. 20K expense with us doing the install. The engine was sent with the wrong head, so JD changed the head at no expense for us. Now...

    JD 350G Fuel rail problems

    The field rep was out of Grand Rapids Mi. Very sharp tech. There should be no low pressure flow back through the feed tubes. The depth of the tube seat is different for the two heads. Your old head was probably the deeper inset allowing the tube to crush fit with the injector. You will need...

    In need of a Komatsu drive motor

    Komatsu lists no parts for repair and no breakdown diagram. There are a few places listing rebuilt drive motors, but for big bucks, 10K+ for just the motor I don't know where they get their parts from, but if I had a source I would rebuild it.

    Komatsu D37Ex drive locking up

    I took apart the hub. There are particles of metal around the seals and bearings, but no clear source. The short shaft that goes into the drive motor is heavily worn, but all the bearings and gears are smooth and don't seam to be where the metal is coming from. Is the drive motor a normal...

    Komatsu D37Ex drive locking up

    I was hoping for some info. I've had an older Michigan apart for seals, but never a locking up problem. Still looking for knowledge if you are familiar with this kind of problem. Thanks

    Komatsu D37Ex drive locking up

    We have a Komatsu D37EX-21, which has started locking the track on one side occasionally. It then requires moving forward and reverse a few times until it releases. I'm thinking something broken in the planetary gears inside the hub, but won't be pulling it down until this weekend. We changed...

    doosan parking brake groan

    I backed off the parking brake to verify it was not coming from there. I was thinking there may have been a residual pressure problem holding the parking brake partially engaged. Parking brake is working fine They are wet service brakes. Dealer suggested when we changed the oil, to pour some...

    doosan parking brake groan

    The noise is in fact coming from the rear wet service brakes. My mistake thinking the noise was resonating from that area. I changed the oil with J20c which the New Holland dealer said to use. The old oil was pretty dirty, and the noise was still there until we drove it a few hundred yards...

    doosan parking brake groan

    We are trying to determine why our Doosan DL220-3 loader ser# DWGCWLATKD1010038 has a loud groan when braking. The sound appears to be from the parking brake during normal braking. The pads are worn, but not at minimum, and the disc is like new. The parking brake works fine when set. I am...
