    Deere 650G final drive

    I have rebuilt the left hand final drive in my 650g direct drive with the upgraded larger axle. It has eaten the seal out twice since we got it back together in a matter of about 30 minutes each time. Is this likely due to damaged on the axle shaft where the seal sits? The lip was chipped off in...

    JD 555G warning light question.

    So I finally found a track loader, in fact I've had it almost a year now. It's a 555G and I love it. It runs and operates great. But now I do have a warning light that comes on and stays on for the most part. It is the "TRANS OIL FILTER" light. It goes out at times but mostly stays on. Can...

    4 Way Blade Adjustments

    We have a komatsu 65ex with 4 way blade and had the arm, with hoses, slip off a couple times before i got it tuned in. Should the 2 tie rods, from arm to back middle of blade, be pulling in to hold everything square or maybe relaxed. I feel like im missing something.

    Detroit 4-71 runaway and diesel in air box

    Hi all, I’ve got a Detroit 4-71 which I retro-fitted into an IH TD-14A bulldozer. Ran great for a couple of weeks, before it started over-revving again immediately upon startup, and sending diesel into the sump. I assumed initially that the run away was caused by the level of oil rising due to...

    D6d vs D5k

    Does anyone have any thoughts on how a d6d long track preforms compared to a D5k lgp? They seem to have similar weights but the 6d has a lot more horsepower. I already own a D5k and it feels a bit flimsy to my older equipment
