What I'm doing: I scored a NOS Nimco loader valve, identical to the one factory installed on my TYM T233. I intend to install it, in the pressure line from the pressure beyond port on the loader valve, and the input on the transmission for the 3-point lift circuit, to control top and tilt on the 3-point. The valve is cable actuated. So, I plan to make a bracket to mount the joystick in/on the right rear fender, so it is easy to get to and run the top and tilt. Joystick forward the top contracts, back the top extends, joystick right the tilt extends, joystick left the tilt contracts. The return to tank line from the second valve would just tee into the return line from the loader valve. My plan is to install a tee fitting at the transmission tank inlet, and tie both "return to tank" lines to that.
I'm planning to make a bracket which utilizes existing bolts in the fender to mount the joystick body under the fender, with the lever coming up above, very similar to how the factory mounted the loader valve. The factory handle is just a hollow 12-mm tube with a couple of slight bends, threaded to screw into the control body. I'll bend some tubing to place the handle just above and outside of the factory control for the 3-point.
The Question: Should I leave a pressure relief valve in the second loader valve in the circuit, or defeat it? To defeat it, I would just add a couple of shims under the spring to increase the pressure it opens at, so the one on the loader valve would always open first. The pressure relief is plumbed internally in the valve body, to flow into the return to tank ports. So, there is no easy way, that I see, to block it completely.
Does anybody see any issues with what I'm planning?
