New guy here, but long time Kubota user. 14 years anyway, I just sold my '95 B 2105 HST, and the very next day picked up my brand new L 3301 HST! I found this forum just tonight, and have speed read through all the previous threads on the loader issue. Part way through I ran out to the shop and noted what you all are referring to. My tractor has 4.9 hours on it, been moving a bit of snow, using the loader and the blower.
Help me out here, it is unclear to me that anyone who has perceived WHAT SEEMS TO BE ( yes it's spread now, but did it come that way) some spreading of the loader arm brackets, BUT has continued to use the loader in the normal fashion.......what have you seen? Has it gotten worse, stayed the same, or caused a problem? My take on it so far is it normal deformation caused by the manufacturing process/welding. I may be guilty of too much faith in the Kubota engineers, but my take on it is that mine came that way, and while it may appear to be spreading, is it really? In other words......has anyone taken note of previously perfectly parallel brackets, and then after working the tractor seen a (spreading) change, and then have it cause an actual problem some time later?
I totally agree the brackets seem lightly built, but not as sure that they present a problem that needs fixing. Now if someone chimes in with major issues and problems caused by simply continuing to run the loader as it was designed (bent pins, binding, weird noises etc.) problems that require an actual fix or repair rather then a preemptive one, it's a different story. So, let's hear the horror stories of what happens if ran as it was designed! I weld, and sure it'd be easy enough to weld a plate across the top, or any other number of fixes, ( but damn I hate to mess up the pretty paint job) the whole area could be gusseted in various ways. I'm just not sure it's "broke". Correct me if I'm wrong, please. I just bought an official spray can of Kubota Orange today, as I'm welding some chain grab hooks to my QA bucket tomorrow, so it'd be easy enough to "upgrade" the brackets IF it's really needed.
FWIW: My background is, home builder/contractor most of my working life, then operator of a crane service the last 18 years, nothing really big and only one. A 30 ton unit with 110' of main boom and 44' of jib, but it's all mine and I make a decent living with it. I also have built 6 experimental category aircraft and am a very active pilot. None of this means squat, but I am considered "handy" by those who know me. If nothing else, now that this matter has come to my attention, maybe I should be the poster boy for not messing with it, spread or no spread! I could take some measurements and write them down, and then work it as normal, and then take more measurements after some time has passed, and see if it stays the same. The "slop" (a negative association, how about "designed working load clearance", that sounds better) between the brackets and hydraulic cylinder is another area that could very well be "fixed", with spacers or large washers, but again, has anyone documented any issues with running it as is? Are you overthinking the issue and seeing a problem where non exists? A presumptive post for my first, straighten me out if I have it all wrong.
