This truck stalls engine when fully tilted back. There is a relief valve on the tilt section of the control valve which is supposed to limit the pressure on back tilt to 1350 PSI so I'm told. The pressure is about 2700PSI and doesn't change at all with adjusting the relief. The pressure does change by adjusting the relief valve for forward tilt though.
We have swapped the tilt pressure relief valve from a know good truck that doesn't stall and it didn't change anything.
Any thoughts. I am in a pickle because I have to deliver the truck tomorrow morning.
