HYDROLIC PUMP BETWEEN DISTRIBUTER AND ENGINE

Eric

The wedge isn't needed on the M because the angle change isn't needed to point the shaft in the direction of that hole in the radiator. The torque motor just bolts directly to the plate.

Be glad you don't have to orient that wedge on the original plate. That was just an old fashioned bugger to get it "aimed" down and to the right, because it needs to set in there "cocked" at about 5 degrees from "plumb" and holes have to be drilled in the plate to mount the whole she-bang. :>(

Your M "should" just be a "bolt on" deal.

I've never seen one, but from your pictures, the configuration appears that your pump is a M&W low pressure power steering pump.

Word on the street is that you don't need the priority valve. Dunno, like I say, I've never seen one.

Your "cylinder" is called a torque generator or torque motor, which appears as if it came off of a John Deere. If you're putting it on an M, you'll need the proper guage panel plate to properly mount it.

Also, it has both "in" and an "out" ports. Get the flow right and hook 'er up. Should work.

If the engine sounds like it is "laboring" and/or the steering "locks up", chances are the pump is a higher pressure pump and you'll need the priority valve.

Don't think so tho.

Thanks for the help, and the pictures it is greatly appreciated, as for the plate I already have it, and mounted it on the tractor.

It is a 201p M&W, do you know what does the P stand for? I'm hoping Power Steering but that seems like it would be to easy!

Again Thanx much,

Eric

Just simply don't know, as I don't use the M&W stuff.

Hope ya get 'er figured out.

A non-positive-displacement pump produces a continuous flow. However, because it does not provide a positive internal seal against slippage, its output varies considerably as pressure varies. Centrifugal and propeller pumps are examples of non-positive-displacement pumps.

If the output port of a non-positive-displacement pump were blocked off, the pressure would rise, and output would decrease to zero. Although the pumping element would continue moving, flow would stop because of slippage inside the pump.

In a positive-displacement pump, slippage is negligible compared to the pump's volumetric output flow. If the output port were plugged, pressure would increase instantaneously to the point that the pump's pumping element or its case would fail (probably explode, if the drive shaft did not break first), or the pump's prime mover would stall.

The main reason I want to know this (if i'm even understanding the difference correctly) is do i need to get a valve to reduce pressure to run it straight to my assist cylinder or can I run the risk of hooking it straight up without blowing the pump, I have the belly pump that runs a Cross three point, and want this pump to run only my power steering, I did find out that it is an M&W.

Thanks

How do you tell the difference between the "live pump" and the power steering pump on those M&Ws?

Just the model number of the pump?

Those things scare me.

Allan

I'm trying to upload a couple of pictures one of the pump and one of the assist cylinder. My big question is will it work to run the pump straight to the cylinder or will i have to get a valve that reduces the pressure?
