Working with a D5H that has slow lift, blade down works as it should, but up is slow. Cylinders are not drifting and the packing has been replaced in the last 6 months And have not had any issues. All other hydraulic components work as they should, so I'm not leaning towards the pump. Any suggestions? Seems weird that all of the sudden just that one function would act up. Is there an adjustment on the valve for just the blade lift? TIA
in lift valve is a resolver valve has seals that has gone resolver in behind alen head plug on lift valve have to take value out to get to it .go thought side panel where tool box is at.
Got it repaired thank you for the replies! Resolver seals were gone, replaced and all is good.now.
