Machine has load sensing hydraulics for most circuits but the steering and clutch/brake booster’s are on a separate circuit. Anybody have a schematic or any insights as to where the relief valve may be ? Have little to no hyd assist. Thanks in advance.
Steering is now basically rock hard to turn at rest and only marginally better while rolling. Could the problem be the orbital valve ? I have 20 Elgin Pelican street sweepers with two orbitals in each and have never had a problem other than leaking at the input shaft. We swapped the cushion valve with no change. We also isolated each cylinder with no success. Thanks for any advice.
Turned out to be a bit of debris in the steering relief valve. Sounds straightforward but it was a real pleasure to get at. Anyway she’s back to steering like a Champion again. Thanks
