Hey guys. I really need some advice here. I have this Industrial 40, with a model 52 backhoe. Today, I cranked it up, drove a little ways and the left hand stabilizer arm was a bit low so I throttled up, and went to raise the stabilizer. When I did that, I heard a loud pop and was covered in hydraulic fluid. I thought a line had burst. But no, the entire stabilizer arm has cracked straight down almost the whole length!

I don't even know if I'll ever find another one around here, there are not a lot of MF industrials in the area. I've barely used it myself, as I've spent a while fixing issues. It's been cursed from day 1.

How does this happen? Wouldn't a pressure relief valve keep this from happening? Even if I find another one, I certainly don't want it to happen again. I would like to hear your thoughts on this.

Diameter of the ram is important for strength when extended as is the inside bore diameter, more than the outside diameter. In this case you can figure the inside diameter as you can see the cylinder wall thickness. The OD minus 2 times the wall thickness should give you the bore.

I drained it. It did have water in the oil, but didn't seem like a huge amount. It was mixed into the oil, didn't come out as water. I don't know if it was enough water to have damaged the cylinder or not. We had a couple of really cold 8-12F days back in December.

I would suggest draining all the hydraulic fluid out of everything just to be sure it doesn't have a bunch of water in it (it's the only other reason I can think of for it to have other parts that are cracked) if you are where it gets really cold.

I don't know why I put ram, I couldn't change it after posting.

Thank you all for your help. I will check the pressure as I know that the caps on the loader valves were cracked when I bought it, most of the hoses had been recently replaced, and the swing motor had apparently recently began leaking badly. All fairly recently before I got it. So I do want to check that before I do anything just to be sure there isn't something going on there. I would have thought a line or something would have blown first, though. Maybe a combination of things.

I did get the part numbers off of it. Early production PN 706107 M91 for the complete assembly, or 1024297M91 for the barrel. 48" when extended, 32" retracted. 4" outer diameter. Thanks for the suggestion of Surplus Center. I sure hope I can get it there. In the meantime I'll get this one out and take a good look at it. I'm fully expecting that the rod has some damage, but we'll see.

I'll let you know how it turns out. I'll read any other suggestions or comments, too. Thanks.

What everyone else said.

It looks like the longitudinal weld in the barrel failed. A real hydraulic shop can replace it. $$$ I would expect well north of $1500. This assumes the piston is fine with NO pits, dings, scratches, rust, ect. If it does, the cylinder is scrap.

The problem with salvage is you won't know what shape it's in until you open it. That's if you can find one.

Surplus Center is the cheapest option. It may be a bit of work to make something work. If it were me? I'd look hard at retrofitting a new one. It's possible the other side may do the same thing.

A few months back, someone was looking for another MF cylinder. AGCO had long discontinued it, but did send him a shop drawing. I'm pretty sure there was enough information on the drawing to make another one.

I would get the measurements off the cylinder and see if you can match it to anything at Surplus Center. They have a lot of cylinders and good prices.

ptfarmer has you answer on repair/replacement, as to why it failed, I lean to a defect in the tube the cylinder barrel is made of. You should check the pressure, but I don't think that did it.

And to be correct that is the hydraulic cylinder barrel that split, not the stabilizer arm. The arm (leg in the parts book) is the rigid part below the cylinder. If you tell people, you are looking for an arm you may well get the wrong part.

If you don't have a parts book below is a link to the Agco Parts book for a 52/212 backhoe. They show three different stabilizer cylinders were used over time. Check for the part number stamped into the base of your cylinder. It is generally good to have part numbers in hand when searching. The cylinders may be interchangeable, I can't say that for certain, measurements may tell. Good Luck

Short of finding one at a salvage yard, a hydraulic/machine shop should be able to replace the barrel as long as the ends are still good (it all depends on how much you are willing to spend to fix it).
