Backehoe cannot lock vertically for stow / travel position.

Need advice for my backhoe problem. I had the right boom cylinder seals replaced because it was gushing oil. I thought that was why I could not get the boom to erect high enough to lock into the vertical position with the little circle lock. Even with the repair I still cannot get it to go up enough to lock in. It's 3-4 inches shy. It's almost like it's hitting a relief valve position.


My HI/LO switch is not currently working so I used the engine throttle lever in the cab to bring the RPM up but not sure if maybe it wasn't high enough or what. RPM Seemed to have no effect on what point at which it would stop moving toward the lock position.

Any advice? I have a gig I'm supposed to do with this baby and I keep having to put it off, first for the cylinder repair, now because I can't get it to fold up!

Thank you so much! I would have never figured that out. I don't understand mechanically how that can possibly work but it does in fact work. Now I can use my backhoe. I took out a bunch of cedar trees outside my fence line today to prevent a burgeoning band of local criminals from using it as cover. Very fast and efficient.

Question: how universal is the front loader mount plate, as in, is it a one-off mount, useful only for the Schmidt FL-4? Can anyone confirm it's versatility? How about versatility of the rear mount point? Thanks for any intel here.

I'm having a hard time determining where exactly this portal axle leak is coming from and thus how to fix it or what part I need? It's the front driver's side axle.

The other axles don't have any grease on them just the green paint. So I guess this one has been leaking for a while though I don't recall it being noticeable dripping onto the inside of the tire like it is doing right now.

4WD and Synch lock still work fine last I checked.


It's definitely an oil leak. At first I thought my omni-pee dogs had gone under there and peed on it but my first clue was that only one was wet. "Hm...they usually mark every tire....something must be up", I thought to myself.

There's really oil all over the whole area at this point. A new development - when I turn off the unimog after using 4WD, a very noticeable air leak is emanating from the axle.

Does anyone have the jackhammer bit for sale that is not the pointing one, not the spade but, but the chisel but that goes in the back of the tool tray? Thanks to Stoik I now have the tray but am aware I'm missing a bit. Is there a commercial one that would fill the space?

Should be standard Stanley stuff. If the jackhammer is also a Stanley, which I don't remember.
In mine, all the hydraulic tools are Stanley. You should be able to buy a new one from Stanley, but I would look on Ebay, etc. for a used one. I've seen those tools on Ebay before. You can look at Stanley Infrastrcture and see all of the pavement breaker bits listed. Handheld Breakers | Stanley Infrastructure I'll try to take a photo of the bit you are missing sometime tomorrow.

Sorry for the delay - I was unable to take the photos until today. The chisel bit has CDB USA stamped on it so it apparently isn't made by Stanley. Attached are the photos.

Alright, I did finally succeed in removing the 3-stage cylinder.
While it's in the hospital getting resealed I'll tackle that uncooperative outrigger again.
.
Anything at all you could share on how to remove it? Or maybe a picture or two? Seems that every time that I do something like that - pictures of the process get overlooked...

Now that I know how to do it, after a fair amount of experimentation, it's quite easy.

Basically, remove the spiral snap ring at the top and drive the rod out of the plate. Next I'd remove the hose from the bottom, which is relatively easily accessible at any time during the procedure.

Next I made a simple eye bolt setup to lift the mast, from the same point that the cylinder would be pushing it up. Then the section where the forks are attached was chained so it couldn't go down when lowering the mast again.

This took a few tries to get right, but left the lower 2/3 of collapsed the cylinder visible from the front. No hoses were stretched or kinked, like I was afraid would happen, and a jack stand was placed under the cast section that supports the cylinder. Which sits loose in that pocket, by the way.

At first the plan was to slide the cylinder out on a pallet fork, or onto a loader bucket, but decided to try with a lasso strap (a typical tie down for car transport) instead, slightly lifting the cylinder that way. Working alone that turned out to be a smart move.
Now the cylinder could be tilted enough to sneak it out, and moved away.

It probably weighs 100 to 150 lbs., so with a bad back and knees, having machinery to do the lifting was very helpful. And a must for raising the mast.
