  • Jubilee Hydraulics
  • Hello everyone, Ive owned my 53 Jubilee for about 3 years now. Admittedly, I am not very well versed in mechanics, but I am will to try anything once! To the point, my three point hyrdraulics have failed. After working perfectly recently, they will not raise when empty, or move at all for that matter. I do not recall the hyrdraulics acting up at all prior to this failure, and I am wondering if there is a starting point for me to attempt to get the hydraulics working again? I will check the fluid, and can also remove the inspection plate if need be. I am afraid that if it is much more than that that I will be out of my league. Might the pump need to be primed? Ive seen a video where the pump is primed via an air compressor. Any help is appreciated.

  • first thing to do is start the tractor and put the lift handle to max lift. then just pick up the lift arms and pump then up and down. sometimes this will prime it. if not-my show jubilee looses prime regular, some of the other dozen or so that i own. just go to harbor freight, or even some walmarts. buy a transfer pump. this is a small hand operated pump. used for pumping bilges out years ago. it has a hose at the top and one at the bottom on a cylinder, pump shaft coming out. all i do is stick the end of the hose into the bleed plug on the pump- them start the tractor and keep it at idle. pump until you get it to prime. shouldn't take more than a half a dozen or so pumps.. when it primes there will be a lot of oil. kill the tractor and put the plug back in. it should work then. on my show tractor i put shutoff and an airhose fitting . i can just slip the pump hose over the fitting and open the shutoff. when it primes. just shut off the shutoff and unhook the hand pump. other tractors may loose the prime accasionally. been doing it for years

  • If the lines going to the pump are not damaged, if you have enough hydro fluid, and the pump is good, you should be able to get it to prime by putting the tractor in a nose down attitude and loosen the plug on top of the pump just so it is loose but don't remove it completely. Fire the tractor up, let it idle slow for a few min and it should get a prime, then when you don't see air bubbles coming out around the threads of the plug, tighten it. Should be all that is needed. Might want to have lots of rags on hand when you do this because some oil will run off pump.
    It could be other problems with the linkage or O-Rings on piston, or pump, stuck valve in control body, etc. I'd try to get a prime first.

  • Thank you. This is a great and easy to understand write up. Iíll try it this weekend and will keep you posted.

  • That was well explained and should work for you as long as you have the round piston type hydraulic pump. If it has the square vane type pump it will not have a bleed screw on it. With the vane pump they will sometimes pick up the prime if you nose it down a steep bank. The vane pump is also the one people are referring to using air pressure to prime.

  • That's one way Mark. Or save a lot of hassles and get yourself a better mouse trap.

  • Re: Jubilee Hydraulics ,Question for TOH
  • Hey Toh, The 3 point hydraulics quit working on our naa, But I don't have time to work on it now,it may be spring before I can get to it. When I do get to it where can I get one of those pumps if that is what I need.Thanks and God Bless, Beth and Allen

  • Re: Jubilee Hydraulics ,Question for TOH
  • Sure - just call/email in the Spring and and get on the list. Hopefully it will have decreased in size by then ;-)

  • I agree Dan, if the pump is loosing it's prime there is something wrong and I would not want to need to bleed the pump every time I want to use the tractor.

  • Re: Jubilee Hydraulics
  • Not a bolt on replacement and will wear out.
    So, how is it a better mouse trap?

  • Re: Jubilee Hydraulics
  • Really? Do you have a lot of experience in this matter? I can assure you the other then the hydraulic line connections it is in fact a direct "bolt on" replacement for the original pump. Takes about an hour to R&R the old unit with the new one.

    The first unit was placed in service December 2011 and is still providing 100% reliable and 100% trouble free service. Reliable trouble free sevice, low cost, and industry standard interchange is why I think it's a better mouse trap. In case you are wondering the follow on units have a similar performance record and I don't expect that to change any time soon.....

    PS> In case you are wondering the follow on units have a similar performance record. There have been ZERO failures and I don't expect that to change any time soon.

    PPS> In case you change your mind and decide you want one the waiting list is quite long so plan ahead....

  • Re: Jubilee Hydraulics
  • Still will wear out and not directly replaceable.

    Long waiting list? Must be great since I can't find anyplace to order it online?

  • Re: Jubilee Hydraulics
  • For someone that knows absolutely nothing about the conversion you are quite sure of yourself. Parts availability and servicability long after I am gone was a primary design goal. It can be serviced just as easily as an OEM piston pump - probably easier than rebuilding the OEM pump and certainly for less $$$$. All wear parts in the pump drive can be replaced with off the shelf items for under $50. If you wanted to replace the pump itself with a brand new one while you are at it cost would still be under $150.

    Needle bearing - B-168 (slightly longer version of Ford piston pump bearing)
    Inner race : IR-121616
    Double row angular contact ball bearing: 5205-2RS
    Pump - SAE-A .55 CID gear pump

    This configuration will last every bit as long as the OEM configuration if not longer. Put your order in now for delivery around Ground Hog day....

    TOH

    PS> Newest wrinkle - customer wants to use it to replace a worn out, non-rebuildable, OEM piston pump with worn out non-rebuildable live PTO auxiliary pump. Slightly larger displacement pump with a secondary priority flow coming soon.....
