Help....Wood splitter fix

[Green Acres Homestead]

Cylinder goes all the way to splitting position automatically and will not retract. I assume this is a valve problem. Before I go buying a valve is there anything else that can go astray that would make this happen?

Thanks

If the cylinder rod will not retract the piston inside the cylinder may have come apart from the rod. The piston and rod are held together with a single large nut.

When you move the valve lever to retract, do you hear any loading of the splitter's motor? If wouldn't be much unless the cylinder is binding. I'd take the retract line off the cylinder, put it in a bucket, and try the retract position on the valve to see if fluid was getting to the cylinder normally. While the hose is off, try pushing the rod back into the cylinder by hand. These tests will tell you if you need to pull the cylinder apart and check internals.

Even if it IS a valve problem, the "O" rings, etc for a valve can be bought for 10% of a new valve cost...

Thanks. I will give this a go.

Did you happen to change the valve for any reason, or install a new valve?

Is the valve reversed?

Are the hoses correctly installed?

What valve are you using that it extended the automatically?

Any pictures of the valve?

No changes were made. Splitter was working now it is not. As for going ahead automatically it is not suppose to do that. Sometime as soon as I start the motor the cylinder goes out. Not sure what type of valve that is on it. I am thinking the valve must direct the pressure to push out the cylinder and will not redirect the flow to retract.

By the way thanks for all your help!

I will post valve picks tomorrow. Just came off a 3 day fishing trip and not feeling to well.

Depending on the brand there is one stud or bolt in the detent section at the rear of the valve that is loose or broken. That bolt compresses a spring to center the spool. The loose part may also be blocking the spool from going back.

Here is an inexpensive log splitter valve.

Another thought I had was that if the nut came off the piston, the fluid might push the piston and rod out, but on retract, the fluid might only push the piston back and leave the rod extended.

A hyd gage would help fix just about all your problems by providing the info for you to make right decisions.

Hi! Check hose connections at valve. IN is from pump and OUT is for oil return to oil tank. on top are front hose and back hose for the cylinder. May be You can have air in the valve . Air is compressible and make lot trouble . Good luck! Oldmech

No way the cylinder should extend "automatically, unless the hoses are on backwards (stand alone unit) or the tractor valve is bungied in the wrong direction. (TPH unit).

No way.

And the winner is jj. It was in fact the nut. How long should that take to fix. Was charge 3 hours.

 

[J_J]

Way to much time to break down the cyl and apply Loctite, and screw the nut on and close up the cyl.

This is a typical example of how a person is screwed and doesn't know it.

Probably did not get an estimate, but even if he did, it would be a lie from the hyd tech.

This job probably only took about 30 min, and the rest of the time he either goofed off or was fixing something for another customer.

It is one thing to run a business and make money, but to steal a persons money is just common theft, as I posted in my other post about [ How is this not theft ]

I wonder how many of them would do that crap if they knew a camera was monitoring their work.

What about punching in on the clock and work on my cyl until fixed, and then punch out and then figure the charge based on work time. Would that not be true valve, and I don't even want to hear about hyd fluid, rags, coke break, head break, overhead.

In the military, when a piece of equipment came in to be fixed, it was logged in an assigned to be fixed, the tech would log in the start time, and end time, and if the time looked wrong upon completion, the supervisor would want to know.

If the parts were available, it was fixed immediately. none of this, I will fix it tomorrow crap.

Your expertise and the ability to get the job done was reflected in your evaluations, and that usually meant promotion.

When working with the splitter was a bit jerky. It then sprayed with force hydraulic fluid out the fill pipe. Took it to a different shop this time and it seems to be working. Taking it to the woods to give it a try.
