Hydraulic Pump Question

Does anyone know what the pressure rating of our hydraulic pumps?...or what the normal pressure should be if one were to rig a pressure gauge at the fan motors or steering gear?

Call source engineering in Oregon. They are experts on these fans.

Ralph,

The Shepard 100 steering box relieves at about #2000 of pressure when you hit the stops.

If a hydraulic test valve is installed in the fan motor system, it must be capable of 5000 psi.

Our coaches only come with single jacket hose. Double jacket can be fitted and there are double jacketed hoses with DIY fittings that can be field repaired once a damaged section has been cut out. They don't bend quite as easily but that should not be a problem.
