Broken Loader Mount; KL4030 & CK2610H

[5030]

If you quit flogging it, you don't need gussets (fish plates).

Glad you got it fixed, and for free to boot! :thumbsup:

I think you'll like using the backhoe loader a lot better than your tractor. Money well spent!

Nice to hear Kitoti will take care of it, not sure it would enter into the pitcher but originally the 2610 was not offered with the KL4030, I know supposedly the set up was the exact same on the 3510 & 4010 and most likely they looked at the HP as a factor for not originally using the 4030 - but it is interesting as I too have moved a lot of stone / top soil with mine with absolutely no signs of wear - When looking at the 2610 I was told the original loader with the 2610 was giving them issues so they went with the "heavier" one - I'm assuming engine placement / angle of arms would be close if not exactly the same on all the CK's - but your story will make me look a little closer at them next time at the dealership....

Thinking about this with the OP latest updates.

Even if he was absolutely bashing the loader into solid rock, there are much weaker points that should have failed. This mount (from memory) is 1/2" steel, the holes (while overkill for the hydraulic qd mount) are spaced plenty from the edge.

I wonder if when some of these plates were cut if they came in from the edge with the laser, and then welded the kerf back up? This would create a weak point that would zipper right open.

I bet they were cut with a water jet, not a CNC plasma cutter. Water jet cutting versus a laser to cause localized heat changes in the crystalline structure of the metal. I have my parts for the shop water jetted usually because the parts in their final assembly are stressed members. Only non stressed parts are CNC plasma and I own the table. Laser cutting is way to expensive for production applications.

I have thought about how this might have happened. The other day I remembered using farm tractors with loaders & when driving into a dirt or manure pile, sometimes the front wheels would come off the ground if the rear wheels had good traction.
Could this be how this happened?

Re: Broken Loader Mount; KL4030 & CK2610H

I looked carefully at difference in fabrication and design between the KL4020 and KL4030 loaders. All pivot points and load bearing points on the KL4020 just appear more strongly made. It certainly appears to be a more rugged and durable design.

If you did that to your loader frame, I would be checking my front wheel bearings.

I seem to remember a while back about Kioti having front hub issues.

Broke last night moving loose dirt? Ya…I don’t think so! It broke a long time ago, judging by the rust in the split. Probably when you were working hard on another project… However not good, nonetheless.

 

[Robin Veerman]

Exact same thing happened to me last night... moving some loose dirt. I don't care what anyone says
You said it...come on now.

Has anyone noticed the KL4030C uses different brackets? I wonder if this is why...

If ever my damn tractor is delivered I'll snap some picture...

 

[5030]

I'd say 'last night' just finished it off...

I suppose it's not as different as I thought.

How long you been waiting?

How long you been waiting?

Only a week; long enough for the anticipation to be driving me nuts, but not long enough for it to actually be an issue. I signed the papers and dropped off the down payment last Friday.

 

[5030]

That isn't a long time. The dealer I work at part time has a number of sold Kubota's (smaller ones) that are sitting incomplete. No loaders to finish them and send them off. Kubota seems to be having issues building loaders for some reason. Not sure why exactly.

Totally bummed! I've got a CK2610H with KL4030 loader at around 185hrs. I noticed that the loader arms were askew while working yesterday and found that the right side loader mount bracket is cracked. We got the tractor back in June so the loader is still on the 12mo attachment warranty. I'll contact the dealer about it on Monday. What do you all think about this being covered? If the parts aren't readily available, what kind of downtime should I expect?

My other options are to buy a new bracket. The partsfiche on Michigan Iron and Equipment lists parts for the KL4010 and 4020 loaders, but not the 4030. M3510-51111 is the right side bracket for the KL4010 and appears to be similar to what I have on the KL4030. I have an email out to MIE to confirm. $640 though...

Or, my friend is a skilled welder. He can weld it back together and add a gusset, if we can bend it back to where it was. I'm hesitant about this option as it looks like the whole plate is weakened. In addition to the obvious crack, there is another one on this plate close to the pivot, which I've highlighted in the pic.
Two of the hard hydraulic lines with the T-fitting on the right loader arm caught the brush guard on the tractor when the loader was lowered while askew, so those are bent and one has a slow leak. Not sure if I can bend them back and tighten the fitting back up, but if not the two replacement hard lines are around $100.

I have the same exact problem. Moving dirt and the loader mount broke causing the loader to fall over to the left hitting the hood and brush guard also causing hydralic lines to hit and start leaking. I was doing normal typical tractor work on two flat ground acres (no abuse). The 1st thing I did was google Ck2610 loader problems to see if anyone else had the same issue and came across your post. Identical to mine! I called my dealer and he said that he seen it before in person and saw other issues on the internet. Immediately he said that the bolt holes are creating an area of weakness on that mounting plate. We both agree that a recall should be done with an updated mounting bracket with more support. He said it should be covered under warranty. He currently has my tractor. I hope they get it fixed! Im still curious if they will take care of the damaged hood and brush guard as well. Ill keep everyone posted!

Another great reason to have the backhoe. Great for breaking up dirt for loader work.

Thought it add to this post. Mine finally gave way last night. I counted 3 cracks on the right loader mount bracket. Same ones OP had. Tractor is 2018 CK3510se. I’ve had it since new. It has 800hrs.

Classic fatigue crack. Characterized by flat surface that collected rust. Fresh metal with jagged break with 45* shear angle was the failure location.

Was moving dirt from a to b when this happened. Definitely a weak point in the system with stress risers allowing cracks to propagate. Left side is pristine. Loader came crashing down on my hood and damaged some hydraulic hard lines.

 

[tacticalturnip]

That's pretty rough, really one hell of a break.

Have you tightened the bolts regularly?
