Single action cylinders

[jfloyd]

I put three point hitch on the mast from an electric forklift and am using it on a 424 international. I don"t have enough hydraulic capacity to make the mast go all the way up and really don"t like the way the pump goes up against the bypass when the mast is coming down. I was considering adding the reservoir from the forklift on the other port from the tractor. I"m not too sure that it wouldn"t just pump all the tractors fluid into the tank on the way down. If anyone has any experience using large single action cylinders on tractors I would love to learn more before I delve deeper into the unknown.

Thanks.

Maybe switch over to a pump ran off the pto and a seperate res. and valve.

If the bypassing bothers you, plug a hose into the unused 1/2 of the coupling pair, and run it back to the tank. (Fill port of the 3-point hitch casting.) Probably have to add a vent, or else weld a "bung" into the cover plate under the seat, and return the oil there, keeping the fill port accessable. That's where the oil from my "add-on" power steering returns.

I wouldn't like cavitating my pump either! Good way to fry it.

One way cylinder is used mostly vertically?
Ram comes out the top?
Some forklifts use the back side (top side) of the ram and a lo press hose for an additional reservoir.
