Problem resolved
Last edited:
I've noticed a few lines getting warm, while the noise is happening i can feel the line vibrating vigoursly, and yes the lines from the valve body were removed as well as the HST Pump. When the control valve was reinstalled it was reinstalled with new bondedAre any of the hydraulics lines getting warm or hot quicker than the others?
Buzzing or squealing noise could be a relief valve operating and that would create heat which is why asking about a line getting warm or hot.
During repairs were the lines to the loader valve removed?
The tractor has 1 HST pump witch is basically the transmission, and has a charge pump to assist in moving the fluid. So technically speaking it has one punp with priority flow controlWere repairs done by a dealer under warranty? If yes the dealer should be fixing this.
Follow the pressure line from the pump to the first valve it attaches to. If designed properly the relief will be in that valve assembly.
Does that model tractor have two separate pumps one for steering and the other for implements or just one pump with priority flow control supplying oil to the steering circuit? Reason for asking is steering is usually a separate circuit from loader and 3 point.
The Hydrostatic transmission is what supplies the implements with pressure, it pressures the entire system including steering. Front end loader. Rear 3 point, and rear remote, it has a charge pump as well witch is only there to assist in pulling fluid. The charge pump is on the suction side of the system, the pump pressures fluid to a diverter valve witch then sends it to either the steering, loader valve or pto solenoid valve.What about the implement and steering.
HST is a totally separate system
Agree since would be nice to know what the solution was after the warranty repairs. Something assembled incorrectly, lines crossed, etc.Very unfortunate the OP decided to delete the opening post.
