The Scv on my 2240 is leaking.JD sells a kit to repair the SCV.Does anyone know how difficult it is to install the kit?

On our 4040 the shop foreman said, you need some kind of a tool, either to take it apart or to set it. When we overhauled them we changed to pioneer ISO fittings, a lot better, now all our tractors are the same. The change was pricey!

Whats leaking the valve or the coupler box?? The valve requires someone knowledgeable in how to adjust the 4 poppet valves. The coupler box is easy.

If it's the same breakway that my 2950 has, you probably don't need the kit. There's some o-rings you can replace with just a hook pick and a steady hand. I was getting ready to buy the whole works, but someone on here (sorry, can't remember who) set me straight about the o-rings.

You're are normally correct if the breakaway is leaking only when tips are plugged in and it's the o-rings that tips fit into. But if it's any other of the o-rings leaking such as on the levers that turn the oil on/off or where the barrels slide out/in then a kit and complete dis-assembly is required.

These are the o-rings/backup washer that you referred to that it requires2 ea for each box.

This is the kit that requires dis-assembly AR82570
