How to adjust a log splitter control valve?

[jodebg]

I have an MTD Yard Machines 25Ton log splitter with an
Energy 92G control valve. The owners manual part number is 718-0481.

When the hydraulic cylinder retracts and hits the end of it's cycle, the control valve does
kick out soon enough and it puts a strain on the engine until it does.

Is there a way to adjust this valve?

Yes, there is a kick out setting.

Install a hyd gage and see what it is now, then adjust it to your satisfaction.

Is this accomplished by removing the relief valve plug and turning the adjustment screw?

How do I install a hyd gauge?

I believe this is your valve.

Log Splitter Valve and Accessories by Energy® Manufacturing Company, Inc.

Install a 3000 psi hyd gage in a tee in the IN port of the log splitter valve.

Thanks for the help.

Haven't done this before. Anything I should know before installing the fitting and making the adjustment?
Can the pressure adjustment be made while the engine is running and system is under pressure?
What pressure should I set it to?

I do not believe the detent is adjustable on the Energy brand control valves. There is a small oil passage in the center of the spool that could be clogged.

Worked on this today. Did not find a way to adjust the release.

Disassembled, greased and reassembled. Now it sometimes works correctly and the next time it delays longer??

Think I am going to add some small washer in the lever linage to take out some of the play..hoping this may help??

If you install a gage in the log splitter line, you will see what pressure the system is generating.

You can adjust the main relief valve by turning the adjusting nut to set the pressure.

The detent may have a set kick out pressure.

the kick out pressures are NOT adjustable.. only the main relief pressures are, here is the manual for the valve, http://www.energymfg.com/pdf/17498X.pdf

Thank You! I now know there is not adjustment and why there is no improvement after removing and lubricating.

Is it worth the cost (don't know how much the upgrade kit is?) to buy the updated detent assembly, or should I just purchase a complete new valve?
