    hi, has anyone had experience rebuilding a dixie chopper hydro transmission? im thinking about buying one that needs rebuilt or replaced. I just havent found too much information on rebuilding it. Where do you get parts and diagrams etc.? Thanks!

    Dixies don't use transmissions. The commercial Dixies use a modifed hydro pump and wheel motor setup. One for each side. There are many places to buy the parts. Dixie Chopper and J Thomas to name a couple. It could cost upwards of $3,000 to replace all of the pumps and wheel motors.

    so can you buy parts to rebuild these components? the guys selling it says that they work now but need rebuilt. and if so, how tricky is doing this?

    Historicaly when a pump or a motor goes out or gives up. A complete failure most of the time it means there are metal filling in the hydro system. When this happens it can not be long before the other half the the system has had these small metal part in it as well.

    A pump or wheel motor that is week but still working, it is a toss up for just how fare along the other parts may be damaged. You will find most dealer that work on a bad pump or motor will not guarantee the rest of the system with a complete cleaning and or complete rebuild.

    If you know its just one pump or one motor you may get by with a complete flushing the system and rebuilding the worn pump/motor. Then all new filters and fluid. Good luck.

    If the pumps are not leaking, the problem could be a worn out hydro pump belt, a fairly easy fix that most guys do not think about when their hydros seem weak. Taking hydro pumps off to put new seals on is a time consuming endeavor, and the air has to be purged out properly or the pump will fail.

    A motor rebuild is more time consuming and more part expensive, But there are many great repair manuals. And the success rate is high.

    Hydro work is much quicker and in some cases and not as expensive. It all depends on to what extent the pump is worn. Check balls, springs and rings, seals are no big deal. But it is difficult to determine if you need shafts and cams or complete castings. (if you and get the parts) Till you get it apart. A good work space, parts washer and lots of patience is a good thing. A real hydro shop will have testing equiment to test the pump to factor specs. Kind of expencive for the guy that dose not do hydro repair a lot.
