BX2200 HST and 3PH

cyates20 · May 4, 2012

I have a bx2200 that I have just had to replace the HST pump due to low pulling power and issues with moving. The 3ph worked perfectly before I replaced the HST pump. After replacing the pump and filling it back up with Kubota UDT, the 3ph will not lower or raise. The linkage is intact. The lift doesn't even try to move. The power steering still works great and the HST drive works perfectly now as well. I am stumped... Any help would be appreciated!

How long have you run it since the rebuild? Have you tried pulling/pushing the 3PH control and holding it for a while? Reason is it will take some time to purge the air out of the circuit. The air will be trapped until you use the 3PH some. That or maybe something in the implement hydraulic circuit got hooked up wrong??

Yeah I have ran it for atleast an hour trying to make sure the air has purged. Moving the lever does absolutely nothing. I have checked and checked to make sure it was full of hyrdo fluid and it is. There was nothing else in the hydraulic part that was taken loose. That is separate from the Hydrostatic pump. I can't figure it out..

Check the hydraulic line quick connects at your loader valve. Make sure everything there is connected properly. If you have the loader off, the crossover line has to be connected.
