Using FEL remote for removable tranny cooler

[Haywire]

I've been thinking about a removable tranny cooler. Seems like if you had an FEL setup, all you would need would be a small radiator with QDs to hook up to the FEL remote and a dc fan with a disconnect so you could take it off easy. Might be able to hide it behind the brush guard if so equipped.

It was brought up that you would need a radiator that is rated for 3K psi. My thinking is that pressure only builds up when you present it with a restriction or load. If it's flowing straight through to the return, the actual pressure would be very low. The only resistance to flow would be the oil passages in the radiator. If they were large enough, pressure would never build.

Another issue I just thought of. If you are dumping enough oil through the radiator to the return to keep the pressure low, the tranny wouldn't have enough pressure to function. You'd be dropping the pressure of the entire system. This is a hydro I'm referring to. Hadn't thought of that before. You'd need some kind of flow or pressure limiter to keep system pressure high and radiator pressure low. They are a heat source by themselves.

Sorry, I'm thinking as I'm typing...

thoughts?

You are right in assuming that the main flow if not used to power a hyd motor or cylinder, is low pressure. After the last valve, it is also low pressure. Hyd radiators usually have about a 300 psi limit .

You could split the main flow in half, and run it through a radiator and fan setup to help cool the fluid. All of this circuit would be low pressure.

Below is a priority flow valve. 6 GPM's is routed to provide basic functions, and the valve routes the remainder of the tractor pump GPM's to another channel/radiator/fan assembly for cooling.

These priority flow valves can be equal or non equal.
