Remote Hydraulics on a 340U

Each HydroTouch valve also has two pipe plugs underneath that close off hydraulic ports. According to the Parts Manual, the original IH remote hydraulics option had hoses tied into a pair of these bottom ports. Here’s my question: does anyone know if those bottom ports are live high and low pressure, or are they controlled by the HydroTouch valve? That is, would I have to hold that HydroTouch valve down to send pressure to the remote output, or would it always be “hot”? I’m planning to use the remote to power a log splitter. Just trying to figure out what I need to do.

Thanks

However, if the original poster insists on going ahead anyway, I would advise him not to bother asking why the hydraulics are slow. They WILL be slow, slower than dirt, slower than molasses, slower than your bowels after eating a pound of cheese, even in perfect working condition when they try to drive a 4"x24" log splitter hydraulic cylinder.

That said, the ports SHOULD be "working" ports for one of the two Hydra Touch valves.

Thanks

You could use a bungy cord.

What do you get for $400? Would that be the 10gpm or the 20gpm? I would get the 20gpm but I think they cost more than $400.

You have other options, I think. Don't utilities have a bolster that allow for the mounting of a pump in line with the crankshaft pulley. Some tractors have a crankshaft pulley with four bolts threads for mounting a splinded flange that accepts a short driveshaft. The other end goes into a pump that attaches to the front of the bolster with two or four bolts. The driveshaft passes through the crank hole. The pump can be physically smaller (and cheaper) because it turns four times faster.

You might also locate a "step-up" PTO gear box similar to what is used on PTO generators. Some generators turn 1800 but most whip around at 3600rpm. A pump attached to the output of the gear box would be small and cheap. A high hydraulic flow to your splitter means you can run your tractor engine at a slow speed. I run my 20gpm pto Prince pump, that pushes a 4" cylinder, at 900 engine rpms. "If you OVER build it, you will ----". Sorry, that was disgusting.
