Somewhat related to my thread below but kinda different, so thought I would ask this separate. Does anyone know if by removing the allen head (yellow in the pic) would provide fluid flow without the M&W valve being engaged or does the valve/pump need to be engaged? Or maybe it has nothing to do with either. Searched all over the www could not find anything on the operation of the valve. Great site, thanks to all

It will have the same pressure as the hose from the right side of the pump that's going in the valve at the 90 degree fitting close to the plug. Those two ports are connected inside. If the liftall rod is pulled back it will have full output pressure unless the remote control valve is moved and plumbed to move another hydraulic cylinder. Then pressure will be lower until the cylinder or whatever reaches the end of movement.
 
Just too be sure, you are referring to the elbow marked in blue correct? Thanks

With the allen head port having the same pressure as the elbow, then that is all the belly pump has to offer, correct? That being the case, I should be able to plumb a line to a charlyn PS generator and it will work understanding there would be an adjustment in flow/pressure once the MW valve was engaged, then full throttle flow once the MW was disengaged or the other cylinder reached its limit. Am I on frequency?

I appreciate other comments and I realize a separate pump such as an truck steering pump would be optimum, just thought I would try this in the interim. Need to fab a bracket etc for the separate pump. Since I have a 51, appears live hydraulics may be possible, which would preclude a separate pump. I guess.

Looked all over www for M operation manual/SPECS, no soap. Thanks
 
That's a IH furnished valve, not a M&W. That port will furnish pump pressure if the valve lever is left centered or the valve outlet ports are not used or blocked. But if you just want pump pressure hook to one of the side ports on the left side. Since the liftall pump needs engaged to pump to use the remote control valve you would have pressure to the power steering all the time clutch is engaged. Then you can still use the remote valve without affecting the PS.
Need a return line from the power steering. Can use a 1/2 inch pipe tee and short nipple in the pump unit drain hole. Tie return line to side of tee and plug the bottom end of tee with removed plug.
 
Learning by the hour. All these years I told my Dad that was a MW add on. Well, if I understand you are suggesting I plumb to the left side of the pump, that is as I sit on the tractor one of the two left ports. I thought one of them was a delay, or so says the M owners manual. That being the case, which port would you suggest I use? That certainly will be better than messing with that remote valve.

thanking again
 
From reviewing the M ops manual, I guess I would connect the service line to the front port on the left side. The rear port is delayed, if I am reading it correctly
 
Doesn't matter on the port for what you are doing. That port is only delayed if a delay lift valve is installed somewhere from port to hydraulic cylinder.
