Possibly reproducing Howard Center Steer parts

I have contacted the supplier to reproduce the Kip valves that are on top and bottom of the accumulator/reservoir. When these go bad they release pressure from the bladder which causes the compressor to run constantly. This in turn burns up the compressor. The minimum order is 25 pcs. I only need 2 for myself. Anyone interested in a spare? They will be Approx $70-$75 ea. I already have a source for the compressor.

Thanks Eddie G.

Mine gets air from the air brake supply. How would I know if those valves are bad? I have noticed that if I don't turn the Howard system pressure knob on the dash control down when I shut down the engine, air brake supply pressure bleeds down faster sometimes and I can hear air escaping from somewhere around the Howard reservoir.

The accumulator has a rubber bladder inside that is surrounded with oil. When the bladder is inflated it pushes the oil with equal pressure to the cylinder mounted to your steering arm. when you turn the system on the Kip valves (2-- 1 on top & 1 on bottom) close to pressurize the bladder ,when you turn the system off they open to let the air escape so there is no longer oil being pushed to the steering system. Since your air source is the on board air system it is allowing that air to escape.The valves have a small barbed fitting that may or may not have a line attached. Either disconnect the lines or find the end. With engine running with full air pressure turn the system on and spray soapy water on them. they should not leak until the system is shut down.
