Adding remotes to a Kubota M4800

[J_J]

On page 37, and 44 of the PDF, it shows the PB port. There are seven ports. If your tractor is closed center, you don't need the PB port. If it is open center, install the PB sleeve, and connect the other valves as directed. Tie all the returns together. Apparently the rear remotes gets the pressure first, and feeds the loader valve. They talk about back pressure through the loader valve presure return line. If you remove the loader, lines A and B must be connected to complete the circuit.

Line B will feel the full 2850 psi pressure when any other valve is operated, and the return port on that valve must be able to handle the pressure. I believe that most valves can not handle a back pressure of 2850 psi.

If the loader valve is attached to the rear remote, the PB is not used.

The hyd supply is at the back of the tractor according the PDF.

OK guys. I'm retarded!!! I looked at the loader valve again today. There are 3 lines. 2 on the top and the PB port on the side. The pressure line comes in from the side of the transmission. The power beyond port goes to the side of the transmission. The third line (return) goes into the rear end housing just above the drawbar. I'll have to put a T where the return goes into the rear end housing. I took pictures, but they on my daughters camera and she is in the bed. I don't know where her camera is.

Now I get to order the valves and lines.

Thanks for all the help guys.

Guess I need to get my eyes checked. :confused2:

Good! You had me worried!

You might want to look on ebay this guy has 2, one he doesn't know what it fits and the other is for the M8200. The valve themself could be the same.
The good part is the price is starting at $6.95, buy both sell the other.

Leejohn,

Thanks for the reply. They won't work. For a much larger tractor. I checked the part numbers on the installation manual he has posted vrs. the Kubota numbers my dealer gave me.

BTW: The dealer told me 2nd set of remotes is just $730.00. He's licking his chops thinking I'm going to buy one :licking: .

Kennyd, JJ, and Rob,


Here are some pics. I think I have it figured out now.

Pic. #1, 2, 3, are of my CCM HTL. If you look at picure #2 you can just see the 90 on the left side of the picture where the return goes into the rear end housing. #4 is the Power beyond port on the loader valve, and #5 is the top of the loader valve.

Looking at picture # 5 the supply line is on the far right and the return is on the far left.

Sorry the pictures are so dark. They were taken with my daughters digital camera and I couldn't figure out how to get the flash to work. :drool:

Thanks for all the help!!!

Looks good Chris! Glad you got it figured out:thumbsup:

Just one note though...You can loosen the compression fittings on each side of that DPOCV (the box mounted on the cylinder) and turn it so the ports are facing the right side of the tractor.

Kennyd,

I know. I loosened them and turned it to the left. That way I wouldn't have a big loop in the way on the right side. I moved the 3pt through all ranges of motion with the bushhog on and didn't have any problems with the hoses kinking. I may try it that way to see if I like it better. Right now I have the hoses tie wrapped to the cylinder.

Thanks for the suggesetion.

Chris,
Great job getting it all squared away (I knew you would!)
That CCM HTL is a beauty ... very heavy duty.

Thanks Rob. That means a lot coming from you. Now to get the HSL and the remotes installed.

Chris.
