BX24 breaking loader pins? (bucket:loader arm)

[EquipmentJunkie]

IC Smoke, I suspect that you are a victim of the dump cylinder geometry of the Kubota BX24. When the bucket is fully dumped, the pivot pins and the dump cylinder pins are nearly in-line with each other. This put lots of strain on the pins when the loader tries to self-destruct in order roll the bucket back from the fully dumped position. Take notice of how extensive the bracing of the mounting of that dump cylinder is on the back of your bucket. I attached a photo.

I grease it quite often, the OD on the boom is good and tight with the pin, Only shock I can think of is when dumping the bucket and it hits the "stops" which causes the bucket to shake somewhat violently.



we replaced a POS JD with the BX24, Nothing but Kubota now (well a couple collector items but they arnt used daily)

L39 is next!

The quick dump feature on a loader places a terffic amount of stress on pins. A loaded bucket weights several hundered pounds and the quick dump feature places the loader bucket in a free fall and the sudden stop of all this weight is what is stressing the loader pins. I always try to dump or empty the bucket without going into quick dump to prevent stressing the loader pins or loader arms.

What the heck would a Kubota owner who thinks Deere is junk post problems with his machine on the Deere forum ? I think he bought one too many Dodges. Sounds like an Orange problem to me. Maybe the Kubota owners never experience failures and wouldn't have an answer.
I looked at Orange when buying and it sent me to the Deere dealer quickly. Just my 2 cents. Like they say, a lid for every pot.

Just to stir the pot a little for fun, I know TBN is not about brand bashing and is a community of tolerance, but since the op brought up the POS comment.

Well I never look in the Kubota forums since I don't own own but just today for the first time I looked over there and the first thread I saw was this,

Is this acceptable quality on a brand new Kubota? - TractorByNet.com

Couldn't believe the nit picking and support he's getting, They really are a different breed!!!

I'll preface my comments by saying that I am a JD fan, and not Kubota.

When I first started reading that post, I had the same opinion of you regarding his complaints on scratches on the wheels of his new tractor. However, the other issue is the weld quality on the loader. Until he posted a new set of pictures much later in the thread, I thought that was nit picky. BUT, the quality of the welds on the loader are HORRIBLE, and do not meet AWS standards. There were even areas where the weld bead strayed off the joint. My business makes heavy ag implements, and we would scrap something like that before selling it to the public. I think he has a definite issue and should have the loader replaced. (just for grins, somebody sent him a picture of the perfect welds on their JD loader)

Back on the picture of the bucket rolled forward, you should never be doing anything but dumping with the bucket in that position. If your in the dirt with it like that your going to bust pins, and run a real risk of tweaking the cylinder piston. One of the most common loader failures comes from guys back dragging with the cylinder extended to the max.

Neil is correct. The bucket edge was just above the ground in that photo and was not being used in that position.

Is that pic of a BX24 bucket? Sure looks different than mine...

If the bucket stops hit the arms "violently" as you say it would be easy to break the pins . The short distance between the stops and the pins would cause a leverage advantage over the pins that would amount to many thousands of pounds . I can't see any reason why the manufacturer would allow the bucket to crowd so far under in the first place (unless it needs that much to dump when the arms are raised) . The angle of the tilt ram is past it's leverage advantage and is such that the ram can't even help with the gentle stopping of the bucket which looks like it nearly free falls before hitting the stops .

My BX24 seems to keep breaking loader pins, I just had to order my 2nd pin from the dealer. Im talking about the pin on the bucket that goes to the loader arms (Not the hyd cylinder mount). It breaks right in the middle where they have made a groove for the grease to go around the pin.

That is very interesting. I did not know that Kubota was grooving their
pins. None of my Kubotas, Deeres, or Kiotis have pins like that. However,
I have replaced 25mm pins several times on two Prairie Dog backhoes. They
had grooves ground in them and that's where the breaks always happened.
The solution on the next generation was to go to 30mm pins and CUT,
not grind a very shallow groove.

What is the diameter of your broken pin?

BTW, I am a fan of JDs, Kubotas, and Kiotis.

The parts manual does indeed show the FEL pins as grooved- kinda surprised me too, I haven't had those particular pins out but others on my BX24 BH I've removed were not grooved. The parts manual shows the BH pins as not grooved....
