How to Plumb a Jinma Front End Loader Valve

Start by looking at the 4 ports on the center of the  Front End Loader Valve,  with the joystick pointing up:

  1) The top left port is the inlet line for the lift cylinders

  2) The bottom left port is the return line for the lift cylinders

  3) The top right port is the return line for the bucket/tilt cylinders

  4) The bottom right is the inlet line for the bucket/tilt cylinders

Next, Install the input and output hoses to the larger ports, one on each side of the Loader valve, as follows:

  1) Disconnect the high pressure hydraulic hose running from the hydraulic pump to the quick connect .  Install a new hose running from the pressure side of the pump to the large port on the side of the loader valve with the arrow pointing in.

  2) Install a new line from the large port on the loader valve, with the arrow pointing out, to the quick connect that was detached in 5) above
