Massey Ferguson 135 Hydraulics

[AW]

I have a MF 135, the lift arms don't stay in position, it wants to keep raising up, won't stay in one position, the hydraulics are strong raises implements fine and loader works fine. I have rebuilt the hydraulic pump, but I didn't replace the relief valve on the pump. Does anyone know what that valve does, and could that be my problem?

Thanks
AW.
