Leaking cylinder with pics this time LOL

teachingscience · Jan 26, 2013

Hi all, I have a log splitter with a leaking cylinder. It is a large cylinder probably 5 inch. It has a packing nut that screws into the head and a ring that surrounds the head.It leads where the head goes into the cylinder ( a stream when I retract the cylinder). The head spins freely and the ring spins freely but the packing nut is too large to remove the ring to see how to disassemble and since the head spins I cant unscrew the packing nut. How do i get this apart to repair the leak?

Any help is greatly appreciated

From looking at it in the pics, it would appear as though the cylinder head is the largest diameter object at that end it should not spin in my opinion. if it does spin, it might be threaded onto the exterior of the cylinder. If so it might tighten using a chain wrench to turn it righty tighty. It might take several revolutions. If it does not tighten, then use that chain wrench to hold it while removing the packing nut and what ever it is screwed into. Jim

Hi I've never seen a cylinder that looks like this to work on. I'm kinda thinking that if it leaks that bad the seals are probably done anyway. looking at your picture on the barrel you have big rusty patches and at the end near the nut, you have straight lines in the paint for say the last 1" to me that indicates a seperate part. I'm Kinda thinking that end part may unscrew and give the access to take the rod and piston out, then maybe you can see how the rest works. Just my opinion from what I see in the picture. Could be totally wrong. What do you think you can see the whole thing in your yard.
Regards Robert

Could you show a couple of closeups of your winch lift system and how it is plumbed into the hydraulics? I need to do that to mine.
Thanks, Richard in NW SC

Just another thought that comes to mind I might be confused by your description of what does and doesn't turn. I have seen 3 other types of cylinder one where you tap the inner end cap in and remove the snap ring inside that sits in a groove then pull the cap and rod. I have seen some where you take the fitting out and there is a clip down in that hole that feeds in that you have to turn out. The last one has a small slot in the outside of the barrel that may be you can't see if its full of junk then a wire with 2 hooked ends cranked one up one down that treads in as a guy turns the nut the correct way. on the last 2 a guy is kinda messed up if its been turned too far to tighten, or a guy tries undoing it the wrong way and the lug/ lugs are snapped off the lock wire clip.
Try those ideas and see what you find too.
Regards Robert

I would get a hold of that "ring" and unscrew the nut so I could see in there.
Tell us about your power unit. Looks like maybe AC 201? What off from? Looks like it's got an aux. tank in the hood? I'm surprised by the distributor. But probably it was added.

Everything spins but nothing is threaded, other than the packing nut. Since everything spins I cant get the nut out. The large ring thats larger than the cylinder is not attached to the end cap. It appears to just hide the snap ring or what ever kind of keeper it has. If I could get the packing nut out I think I could get the ring then see what holds the end cap to the cylinder.

Cylinder looks like what's on my H60B loader. I have a similar problem don't know how to fix it either. Maybe someone who has dealt with Hough loaders can help.

Ask on the crawler forum. There may be someone there that has worked on a cylinder like that.

Looks somewhat like a rig I encountered once. Release all the pressure from the cylinder and lines. With the rod extended some amount, push the nut and inside seal INTO the cylinder and see if there is an internal circlip ring inside of the cylinder. Once this ring is removed, the piston , packings, and rod will slid out of the cylinder. From the looks of the nut, it should slide right past the collar on the cylinder, the circlip will actually be on the inside of the cylinder, and prevent the packing assemblies from moving out under pressure. It just looks like a round wire spring in a groove inside.

Thanks very much.

I would take the hydraulic hose and fitting out,the snap ring may be hiding inside there since you don"t see any other places it could be hiding. Joe
