Allis Chalmers 160 FEL plumbed wrong

Any casting # on that valve ?

I'll take a look and let you know.

So. you are saying that you have to hold the FEL lever fwd to operate the 3pt. What do you have to do to operate the FEL by itself? Seems like the fluid would go back to the 3pt and back to tank, with nothing happening.

This valve, plus the PB sleeve would solve all that.

The FEL operates fine with no monkey business.

I think the reason for this is the FEL valve is open center so the fluid flows through the valve back to the sump, rather than to the remotes and the three point, as flowing back to the sump is the path of least resistance.

I'll admit I'm having a tough time making sense of this system, I do have a diagram in the I&T book for the way the system was plumbed stock, I'll scan that and post a picture of it.

Thanks for the link to the valve, we bought one of those when we redid a loader on our Kubota B7200, are you saying with that valve the loader would be plumbed as it is now, with the outlet being a return to sump, and the PB going on to the rest of the system?

What exactly is a "PB sleeve"

Thanks,

Erik

The Pb sleeve block off the hyd fluid from going out the OUT port, and sends the fluid downstream. After you install the PB sleeve, the only fluid coming out the OUT port will be work port fluid, fluid used to operate the cylinders.

This is a PB sleeve that goes with the joystick valve.
