Back leveling roller won't go up?

[WellandportRob]

The back leveling roller on my LT-40 won't raise. Levels are good and the front one works no problem.
Any Ideas?

can you here any kind of reaction of the hydraulic system at all?  Or is it like the valve is not putting fluid to the cylinder?   If I were to just shoot in the dark, I would suggest the spool is not moving allowing the fluid to actuate the cylinder.  Seems like there's a spring and detente, just behind the lever that is connected to the spool valve, seems like sometimes these springs break or something like that,  not seeing its hard to even say,

Hello,
    I suggest you turn ignition key on accessory. Activate the rear toe board lever. You should hear the hydraulic pump . If not hold the hydraulic lever for the rear toe board and activate one of the other levers just enough so the pump comes on. The toe board roller should move.
If the hydraulic pump activates with the rear toe board lever but the cylinder does not move. I am not sure, I have seen very few issues with toe boards. Most common issue is the hydraulic switch needs to be adjusted or the lever for the valve spool needs adjusted.
Hope this helps.

Can not seem to find the exact picture but here are some close.

Thanks Marty,  I'll give it a shot and see.  I appreciate your response.

Huh, my box don't look near that clean. I do like the idea of a different shaped knob on the turner/back support handle. I have no idea why I haven't done it already. Much of the equipment I have run over the years had different shaped knobs when they were close together to help differentiate them by feel. I'll have to make some changes.

My clamp didn't want to work properly so I readjusted the switches on my LT 40 and made a lot snappier response.  Getting that 3mm Allen wrench in to adjust was a little tight as I have command control.  My book said not to adjust the first two switches as they were factory adjusted.  Good thing I have small hands.

Me too!! A simple but brilliant idea.
