Electric third function control valve install.

countrybumpkin · Sep 15, 2009

I have finally got to start the install of my full function third valve on my Kubota L3410.

Here is a few parts I started with.

I decided to mount the valve and subplate in front of the right side floor board under the loader valve. I made a bracket out of 1/4" aluminum plate that bolts through the top of the floor board and the side also. One reason I mounted the subplate here, the existing power beyond hose ran right through this area. I was able to cut the hose in half and add two new ends to plumb the hose through the subplate, saved the cost of two hoses.

Here is the DO3 subplate mounted.

I ended up using this joystick controller I had lying around.

I also ran two outlets to the rear of the tractor to use for rear remotes.

I hope to do the wiring and finish mounting both sets of quick connects in the next day or so.

Finally got everything finished, after a bunch of delays, nothing to do with the tractor or this install, but always something else popping up and having to take care of before this project.

Here is the rear set of outlets, I used a tee at the valve on both outlet ports and ran a set of hoses to the front and rear of the tractor.

Here is one of the valve installed on the sub plate, also I took a brass thread barbed fitting , had ½” threads and a 3/8” barb. The valve has two nylon plugs screwed into the electrical housing, so I removed one plug and reinstalled a pipe plug with sealer in its place and the other side I installed the brass barb fitting with 3/8 rubber line to run the wires through up into the dash, nice sealed connection that way.

I also wire up a “Master on/off switch on the dash, so when I don’t have anything hooked to the valve outlets I don’t accidentally hit the buttons on the joystick and pressurize the outlet lines, it would probably never cause a problem but I don’t have to worry about it now. I also installed two extra switches while I had the dash apart and wired them up for front and rear work lights to be added soon. All with weather proof covers.

and finally the front set of outlets (I had to wire tie them out of the way while the bracket was being painted.)

I also wired up a second SPDT lever switch next to the seat on the right side, that way I don’t have to mess with the joystick while using the rear outlets for a disc or other rear mounted attachment, sort of like how the factory rear remote lever would be.

Very cool project and nice progress.
I especially like your idea of using the brass barbed fittings and hose to run the wires in.
Very good idea!

countrybumpkin,

In the fifth picture.

If those 45 degree fittings are galvanized fitting, I would exchange them out for 3000 psi hydraulic fittings. I don't believe they will take full pressure.
