Wood splitter valve

Anonymous-0 · Mar 12, 2009

My wood splitter has auto return on it, just push the lever up and it brings the ram back up while you get another log or what ever. Recentely the handel keeps clicking off, sometimes I have to hold it up. It says energy on the cap on top of the valve, does anyone know what is causing it to not stay up like it is supposed to. I was gonna try taking the top cover off (2 screws) and seeing if maybe its gummed up or something. Thanks for any info Ps the splitter is made by speeco.

Jay,
Now I know there has to be a "right" way to do it but I was using my Son's last year and it was doing the same thing, I got so Da-ned frustated I hooked a spring to it with just enuf pressure to keep it up for the return. I did a pretty good job of installing the spring and altho I intended to take a closer look at it for a better fix, I just never got "a round tuit".
He's split a lot of wood with it himself since then.

Slide going back hard?
Filter getting plugged?

USUALLY WHEN WE SEE THIS THE SPLITTER HAS DEVELOPED SOME RESISTANCE IN THE SLIDING PART OF THE RETURN STROK. LITTLE WD 40 OR GREASE MIGHT HELP. THE VALVE IS GETTING TO MUCH RESISTANCE IN THE RETURN MODE. SOMETIMES IT IS IN THE VALVE DETENT SPRINGS BUT LOOK OUTSIDE FIRST.

Thanks J.W, I should have said this splitter is a 3pt that runs off the hydrulics on my tractor.
Sometimes when I move the hydrulic lever under the seat of the tractor it wont stay open. In other words I have to move a lever for the remote hydrulic lines to work. I cant explaine it better for you. When I use may baler, I have to tilt the thrower with a lever (scv) maybe, under the seat that goes to the lines on the back of the tractor. I will look over the splitter tomarrow. Thanks

On most brands of auto return valves, when put in
the return position, a couple of spring loaded
B B size ball bearings slide into a notch at
the back end of the valve spool. When the cylinder completes the return stroke, and can't
move any farther, hydraulic pressure forces the
balls out of the notch, and the centering spring
returns the valve to the neutral position. When
this type of valve fails to lock in the return
position it's usually because the balls have worn
a groove where they ride into the locking notch.
Some, better quality valves have a replacable
insert on the rear of the valve. On others, built
to sell for a price, rather than to a standard
of quality, (cheap valves) you may have to replace
the valve if you want to keep the auto return
function. A GOOD professional hydraulic shop will
have parts breakdown literature, or can tell you
if parts are available. Splitters sold by chains
such as Home Depot, or Tractor Supply Stores
usually won't have the quality valves.
