Iseki TS2810 - fitting spool valve

[melovelo]

I have an old Iseki TS2810 which still runs well. I壇 like to fit a double acting spool valve to the hydraulics but don稚 know where to start. Can it be done? How is it done? All advise welcome.

If you have no existing spool valves installed and only the 3 Pt then I can tell you how I did my Yanmar FX24d. I cut a short section out of the high pressure line. I then installed a compression fitting on the two remaining ends. From there I attached a line from the cut line closest to the hydraulic pump. Ran it to the input port of the spool valve. Then I ran a line from the return port to the other end of the cut line. That leaves two work ports, out and in, to the device you are adding on a single spool valve.

Cutting the high pressure line is not hard. Just use a plumbers cutter. My compression fittings never leaked.

Measure the outside diameter size of the pressure hose to get the appropriate compression fittings. Then match the pressure fittings size to the hose fittings needed for the new in and out lines to the spool valve.

DO NOT JUST TEE THOSE LINES! The flow needs to be interrupted and re-routed to the new spool valve and then back to the cut circuit.

Thanks for your reply and suggestion as a way I may accomplish this. The tractor does have a valve already fitted but I assume it is a single acting valve that was possibly used to tip a trailer as it has one outlet hose with a quick fit coupling on the end. The valve lever pulls up which pressurises the hose, returns to a central position when released and pushing down you can feel the hose relax so pressure is released.

There is a plug on the opposite side of the valve to where the hose attaches but I don’t know whether this can be used as a return feed from rear remotes or not
