My 140H-1 seems a bit slow in the hydraulics, mainly when cold. I have heard people talk about resolver valves becoming faulty which can cause this drama. I will check pump pressures this week but thought maybe someone can shed a bit more light on the subject.Cheers

The Resolver network collects the highest work port load and sends it to the pump control valve to increase output to match circuit demands. If the signal leaks off through the resolver network the output will be low. Try pulling other levers and see if things speed up.
