New PTO wood splitter......problems with dead heading the tractors pump....

[MotorSeven]

I just picked up the Northern tool 20 ton dual action wood splitter. Had two hoses made and connected them to my rear remote. Detent balls are back in the tractors remote lever. After 5 min it deadheaded my pump...what do I need to keep this from happening?

The splitter:

Ckeck your quick couplers, sound like one came unpluged.

Did you reverse the A-B switch on your rear remotes? If that is not it, it sounds like your tractor is not putting out enough pressure to kick off the return detent on the log splitter. There is an adjustment on the splitter valve that allows you to change the pressure at which the splitter detent kicks off.
However, most likely QC came undone as per Leejohn or you are plumbed backwards.
That DK40 should put out plenty of pressure for the 20 ton splitter. I can only run 14 ton splitter on my CK20, but it is enough for an old guy like me.

Gil, what do you mean reverse the A B switch? No, the QC's were both locked in & I'll have to look on the splitter valve for an adjustment. GPM on the DK40 is 16.8....more than enough flow and no the splitters return detent was not kicking in so I was not even running it all the way to the end of the stroke.

On the CK 20 the lever to engage the rear remotes has a A and B setting. Changing from A to B reverses the flow to the splitter. If the flow to the splitter is going the wrong way, you are just dead heading the pump. If you do not have an A-B switch, it is just as easy to switch the hoses from the splitter to the tractor.
I assume the splitter came from the factory already plumbed so hoses to the valve in and out and valve to cylinder are installed properly. I bought a used splitter and found out, after splitter detent would not work, that the hoses on the splitter (valve to cylinder) were reversed.
GPM and pressure should be fine on the DK 40- you only need 1800 to 2200 PSI to kick the detent. GPM only affects speed of travel.
That is a two way splitter so it must have a return kick off (detent) on each end of travel. Not to sure how that affects plumbing, since there is no forward and reverse.

In order to check the hyd plumbing, remove what you think is the pressure hose to the splitter and place in a bucket and see if there is flow after you have placed your remote in detent.

If you have flow ,that part is correct.

Now, make sure you have a return hose from the splitter valve to the tank.

Make sure your QD's are flowing correctly.

Did you actually split wood for 5 min, extending and retracing the rod several times.

If it was working then, then perhaps a QD came loose.

With all valves in neutral, there should be flow through all valves except the log splitter valve.

Gil I don't see any A B setting and yes the splitter is supposed to kick out at max travel in both directions.

JJ, I never thought about flow direction to the splitter valve and changing that is just reversing the QC's right? So flow through the splitter valve only goes one way and if the QC's are reversed it won't work at all? However, yes it did work for 5 min before it stopped. I will determine which one is flow and which is return tomorrow.

I appreciate the help:thumbsup:

Sitting on your seat of your tractor on the right about knee high is a shift rod that goes up for A circut or down for B circut.

Are you talking about the A/B on the FEL lever? I have that, but nothing on the other two rear remote levers that are next to the FEL lever.

Do you have two levers for remotes? if so you have A,B,C and D on the remotes.
