  • Naa hydrolics chatters
  • I bought a ford 1954 naa about 3 years ago,when I bought tractor 3 point hydrolics were fast and smooth. Ichanged out all the fluids including the hydrolic system,initially it lost it prime and I got that taken care of. Ever since I got rid of the old hydrolic fluid it lifts up ok but it chatters when going up.this is most apparent when there is nothing attached to the 3 point. When I put heavy blade on 3 point the chattering is not as noticeable. But like today with 3 point ford boom hooked up the system chatters and rattles instead of going up smooth and quitely. Iam running an all purpose hydrolic fluid from tractor supply because it is way cheaper than the new holland hydrolic fluid. Do I need to run ford/new holland fluid to get her to lift correctly or is there some thing else I should do?

  • Does the tractor still have the original vane pump or has it been converted to the newer piston punp?
    If it has the vane pump I don't know why the chatter. If it has a piston pump it is likely one or more of the pistons giving out.
    Piston pumps are simple to rebuild and parts are not too expensive.

  • I bought tractor and it has to new piston pump not the original vein pump.
    Still baffled why this happened after changing the fluid,with old fluid it was fast and smooth.
    With new fluid it lefts ok and holds implements up fine the choppy chattering is bothersome.
    Would different fluid brand help or an additive there was some water it old fluid.
    Thanks

  • One thing you can do to rule out one component as the culprit is to take the right side round cover off and watch the lift cylinder while it is lifting. If you see a lot of oil coming out of the lift cylinder, you may have found at least part of the problem. O-rings or scored cylinder. If you don't see oil coming out of the cylinder, the problem may be due to the condition of the pump or a valve operation.
    the Pump needs to be in good condition and hold its prime. The top cover may leak at the right front corner or leaks can come from the lift cylinder or the gaskets/seals between the top cover and cylinder. The linkage needs to be set properly and the cam follower pin needs to be in good nick. Oil needs to be fairly clean and water free if possible. The valves in the control body need to be free along with the relief and back pressure.
