Hydraulic Motors

Anybody got a problem with this?

Vehicle is a Clark C-40 forklift. Probably forty years old.

Output port from the original two valve (lift and tilt) goes to a four circuit Vickers forklift valve. A selector on the return port reduces back-pressure on the original two valve and makes the gravity down function quicker when forks are not loaded.

Of the four circuits (a) runs a hydraulic motor that drives an IH Balanced Head sickle bar mower in both directions. It's a hedge clipper now. (B) runs a cylinder that folds the sickle bar, (c) runs a hydraulic winch on the mast, and (d) will run a direct drive (from a Detroit Diesel) air-brake air compressor on one port and a Getec 4000W generator which is also direct drive. Both accessories only need to run in one direction.

Are you confused yet?

BYW, I need one handle for the Vickers. Local shop has one but I don't want to pay his asking price of $50.

Also looking for a gas grill that will tie into forklift propane tank. (Just kidding)

978 851 six three zero eight.

Oil return is via original hose.

Not sure of cycle times. Air compressor has a 9 cubic in displacement Charlynn gear-roter. I haven't powered it up yet. I may swap in a 4.7 cubic in similar motor. The Getec is an engineered product. The generator currently turns at 2200 rpm at engine idle. Will have to use a hand throttle to achieve 3600 rpm.

I think reservoir is about ten gallons. I changed the oil last fall but can't remember how much I put in.

Every thing on the multi-function forklift works fine so far. It even functions as a forklift. I'm adding the air compressor now. It is surprisingly nimble without the counter weight. Capacity is down to about one ton now.

It should work fine. You could also try plumbing the motors in parallel and putting a oneway check-valve in one line for each motor to prevent them from spinning in the wrong direction. This way they could both dump back through the spool valve and still only run in one direction.

Your way is probably less complicated...
