John Deere 2030
Hey all,
I have a John Deere 2030 with a 1650 backhoe attachment with a long dipper arm that managed to bend one dipper rod and then break it's replacement rod. The gent who cleaned up the cylinder and put the new rod in warned me that rods just don't bend ( or break) unless something was dropped on them ( like a tree) or there is some misalignment in the arm somewhere. Not knowing the history of this tractor, which I just got last summer, I assumed it got beat and had a ding in it. the replacement rod lasted, and I crap you not, about 3 hours before I broke it.
to provide some background: i have used this machine so far only to dig our well line trench, footings for piers, and our electrical trench. When the first rod bent I was working close to the operator's seat with the bucket almost perpendicular to the ground trying to chisel out a pine stump. I was rocking the bucket towards and away from the tractor trying to chip the stump loose, sometimes lifting the back wheels up while applying downward pressure with the dipper cylinder fully extended. This is when the first rod bent. the second rod broke while I was working in a similar position (close to the operator's seat) but only digging sandy loam soil from an 18" trench with the bucket, i.e little to no downward pressure. FWIW the dipper cylinder was painted a different color from the others, perhaps not original and possibly replaced before.
I contacted the gent who fixed it and he said that something's out of alignment, or worn, or bent. any thoughts on what might have caused this, or what i might look into doing to fix it? Obviously the repair bills have added up quickly and I'd like this fix to be it's last! Any thoughts or help are greatly appreciated!

Pictures are always a big help in these "I've got a problem" posts. That way we can all see what your talking about and often notice something before you do. Have you checked out your mechanics suggestion that something is out of line. Look at the dipper arm itself or put a straight edge on it to see if it is twisted or otherwise not the way it was originally made.

Take the unit to him and let him look at it.

Sounds like you have a faulty circuit relief valve in the dipper or boom circuit.

And this would be inside of the valve? in my manual it looks like a little o-ring. What causes this to fail? age? crud? the cosmos? there are definitely some leaks in the controls valves that I haven't had the time or inclination to shoot. Hydraulics are new to me, and I was under the gun last summer to finish building our house before the snow flew, didn't have time to tear it all apart....

Point taken, though i'd like to have an idea of what may be the problem before I pay someone to haul it down to him and back up!

I checked the dipper arm and nothing seems to be awry as far as a bend in the frame, but the head of the dipper does look a bit askew. Only had this tractor a year and am still getting to know it, and what is permissible as far as play, tolerances, etc. And this is my first tractor, period! So here are some photos, hopefully you can see what I'm talking about. The head of the dipper piston rod looks a bit cocked in relation to frame on the dipperstick, and on either side of the (broken) piston you can see that there is more of a gap between the left side of the dipperstick and the boom than on the right side of the dipperstick to the boom. Perhaps the head of the dipperstick got bent, or maybe the pin that holds the dipper to the boom? or is that not a failure point? not the best light for pictures today, i'll try again when the sun comes out.

vtsnowedin, do you know any local folks who work on things like this? I'm planning to bring the rod back to the guy in Bellows Falls to have him fix it, but would love to not pay hauling the entire tractor there and back.....thanks in advance! IMG_4605.jpgIMG_4607.jpgIMG_4608.jpgIMG_4609.jpg

The guy that used to be my go to person for anything diesel or hydraulic has retired. He's still in his shop most days puttering around but doesn't take in any for hire jobs. I've had good luck lately with the guys down at Trottier's in So, Royalton. Of course I bought a new tractor from them so that might have something to do with it but as far as I can see they are straight up and know their stuff.

What does the other end of the dipper cylinder look like. Does it have a ridged mount or can it flex around a through pin?
