    Default Broke my BH

    I bent the bucket curl cylinder rod into a pretzel on my JD48 back hoe. I was digging out a stump like I did many times before when I heard the screaching sound of metal on metal as I tried to curl the bucket. I am still not sure what happened to cause the rod to bend but in any event I will need a new hydraulic cylinder when I can afford one. Does anyone have a guess how much a cylinder will cost?

    db4700 the cost of one of those cylinders out weighs the cost of just buying yourself a new JD48 backhoe. If you want I will buy the one you have now though and maybe I will just part it out. [img]/w3tcompact/icons/smile.gif[/img][img]/w3tcompact/icons/wink.gif[/img]

    Actually there were some later back that experienced the same thing and I think if you do a search for them you will find some helpful info. As far as cost I can't see them being too much,,,,total guess but no more than $150. ????? Boy looking at my #7 backhoe the cylinder size is about the size of a big salt pretzel.

    Shouldn't be more than a couple hundred for a new cylinder (unless it's painted green - if so, double it). You could see if it can be rebuilt. I snapped the rod on the extendahoe cylinder for my Case 580C, and that cost me C$900 to get rebuilt. I subsequently discovered that it had been contracted out to a local hydraulics shop and if I would have went there it would have cost a lot less.
    I would remove the cylinder and bring it to the local hydraulics shop. If they can't rebuild it, at least they can tell you exactly what the replacement should be.

    I seem to remember that this was a common problem on this model hoe. I think it had to do with the cylinder stock was not heat treated all the way through. Do a search in the archives on this. I think that JD was covering this under the warantee since this was a known problem that many were having. I'm sure some other TBNers can respond here. How long have you had the hoe?

    Darin, Thanks for the hint to do a search. I found a few similar instances. Based on what I read it looks like your guess may be off by about $500! I guess I will learn to live without the use of my backhoe. [img]/w3tcompact/icons/frown.gif[/img]

    Boustany, I found a post where someone needed this cylinder for a New Hooland BH and it listed for $585 so I would bet the JD part is $685. My dealership is small and the parts guy is having to serve as mechanic for today so I can't reach him to get a price. I wonder if I could get away with buying an aftermarket cylinder and welding the old bushings on it it.

    I bought the BH in March. I used it a lot at first to dig stumps and to put in a culvert but it has been mostly sitting for the last three months while I built fences. I hooked it up yesterday to dig up a few stumps along the fence line before I strung the wire. I had no problem with these stumps but I just had to stop and get one more stump on the way back to get the box blade. This stump was a stuborn oak that did not seem to want to budge. I kept digging and put the bucket down behind it to check if it was ready to give a little when I heard the screaching metal sound. I thought I must have bent the bucket and was really supprised when I got off the tractor and saw the cylinder shaft. I described it as a pretzel but it looks more like a corksrew. I wish I knew why this happened and how I can prevent it from happening again. I doubt I will ever feel very comfortable using this implement again for fear that it will bend another shaft.

    With those prices, all the more reason to visit a hydraulics shop or even find out the specs and order one from away. I believe cylinders are pretty much standard sizes, even though the ends (bushings) may vary one to another. If I thought I could save a few hundred bucks, I'd sure look into it. I dealt with one cylinder repair job via courier once, so it is doable.
    I bet you could get a new replacement for less than $200, surplus or used, even less. Welding bushings onto an aftermarket cylinder is a standard repair, so you might go for it.

    Check out this post, this guy got it covered by JD and it sounds like he was doing exactly what you were doing....

    I went out after supper today to dig out some 4" & smaller tree stumps with my JD4400 & 48 hoe. It was just getting dark and I was about to quit but decided to do one more. I was reaching over and digging behind the stump trying to pull it out. I went to tilt the bucket back, it made a loud squall and stopped. I got off to see what the problem was. I could not believe what I saw. The bucket cylinder shaft is now bent in an L shape. Has this happened to anyone else? I knew I should have gone back to the shop and worked after supper. It was in the archives I did a search on back hoe bend and that is what I found.....

    You forgot to include the post or the identity of the post that you were talking about.
