Back in the summer of 2023 I installed a rear remote valve on my L185. I really never used the tractor for any length of time since then until last weekend. I was shredding for about two hours and noticed the tractor was struggling a bit with the load.
I touched the hydraulic pump and it was pretty hot and so was the rear remote valve.
There is a high pitched noise in the rear remote valve that I assume is something limiting the flow of hydraulic fluid through the valve.
The valve is a Bucher valve 12 GPM version that has the numbers 19-4 831000011 cast near the T port
The P port is connected to the pump out put. The power beyond sleeve was installed and labeled and is routed to the three point valve feed. The T port dumps to the top of the transmission case.
All hydraulics work correctly. Rear remotes move both directions and go into relief at end of their travel. The three point hitch moves up and down and will go into relief when lifting the shredder off the ground when it reaches top of movement.
I hear a noise constantly from the rear remote valve except when I adjust a cylinder or adjust the 3PH. The noise goes away but returns when lever is released.
I am going to take the valve out of the circuit and run it again if I can get some caps and connectors tomorrow morning. I plan to connect the hoses from P and PB together and cap off the valve fittings.
I just have no idea how to fix the valve if the problem is in the valve itself. So the question is how to resolve an issue with the valve limiting the flow and increasing the pressure on the pump?
I will post pictures of the system and valve in a second post
