Help with log splitter

[hwatkins]

I built a three point hitch log splitter, the detent is supposed to operate the B Port. I have the B port hooked up to the lower part of the cylinder, which should cause it to retract, but instead it causes it to extend. The other issue is the valve is supposed to have a rapid extend feature, but when I try to engage that the ram sputters, like it can't decide if it should move up or down.

I've gone over the hookups but can't see an issue. I've attached some pictures to show the hookups. Any ideas on ways to troubleshoot?

It sounds like the hoses are hooked up backwards.

It sounds like the hoses are hooked up backwards.

Unless the documentation is wrong, I don't see how I have it hooked up wrong, this is the hydraulic circuit below:

Pressure Release Detent:
This feature provides a pressure release detent for the pool 'out' (handle in) position. When the spool is manually placed in the detent positron oil is directed to the 'B' work port (the port away from the handle). When the pressure in the 'B' port reaches a preset level the detent will release and the spool will center.

The IN hose and OUT hose are reversed.

The IN hose and OUT hose are reversed.

The B port is toward the handle.

Click instruction sheet,

Tank pressure is only 150 psi.

You may already have damage the valve.This valve is a regen valve.

If you hold the handle full out, the cyl will extend rapidly. Power mode is fro neutral to the soft stop.

Did you not have instructions with the valve?

The port is labeled B as the one away from the handle on the top, the in port is labeled to the left of the handle looking at it from the top. I don't think I have those reversed.

The picture of your splitter control valve shows the hoses the opposite of what the illustration shows.

You are looking at the wrong valve a LS-3000

You should be looking at a LSR-3060-3 which is illustrated in the PDF I posted above.

Don't know who helped you out, but they did you a disservice by lack of knowledge.

A LSR -3060 is disigned to be used with a low GPM pump.

It takes say a 4 GPM flow rate and makes it into a 24 GPM flow rate.

So with that PTO pump, you are asking the 11 GPM valve to support a 44 GPM flow using the regen mode.

If you are going to keep the PTO pump, then get a regular log splitter valve.

It is possible that you could run the engine low enough for a low GPM flow and still use the LSR valve.

JJ not following you, the LSR-3060-3 is the same port configuration, this is from page 18, port B is away from the handle

It does look like they show port A and B going to different ends of the cylinder though. Maybe I'm confused on which direction the fluid flowing would make the cylinder move, I assumed fluid going in to the end near the rod would cause the cylinder to retract
