Do you think that the flex on the Case is from wear and / or design flex?

As far as the "chicken or the egg" question I would have to agree that the flex caused the cracks and then the cracks allowed even more flex. I think it is shortsighted of a loader designer to assume that the loader will not be sideloaded and the loaders should be able to withstand maximum loading on one corner.
I noticed that the flexation increased and the creaking noise which caused me to inspect and then identify the cracks in my loader.
Great thread by the way. The flexation of the CK20 loader in the beginning appears excessive. A flat concrete surface is very important for this comparison as well as a head on shot since angles can be very deceiving here.

Here is my DK45S with less than 100 hours. Nothing on the back or the belly. I used 2 6x6 blocks to get a good view. At least 4 to 6 inches of flex.
I did notice at least 2 inches of movement where the quick attach plate catches the lip of the bucket. That also has to be taken into consideration. I have never noticed any flex in the loader during normal work. I don't normally use the corner of the bucket for digging or lifting.

Highbeam, How much deflection do you get in your newly reinforced loader?

I don't have my digtail camra. The wife has it and she will not be home until tomorrow. I would like to know how much Kioit's Johns loader flexes.
Thanks
Glen

I was out brush hogging all day yesterday, couple new dents, and had I seen the thread I could have taken some photos. I'll have to do the test. I would also like to add that I consider pushing down with the loader, as in to backdrag, pretty normal use and often find the front wheels lifted off the ground here and there as I rake in reverse. These loadings aren't totally out of the realm of reality and the flex of the loader arms on the downstroke should be the same as on the upstroke.
Tomorrow is race day. Our first enduro motorcycle race of the year with 74 miles in the saddle of a dirtbike. I'm getting geared up for that today.
Does the 45s have a through-put torque tube? Like the Kubotas?

</font><font color="blue" class="small">( Why did the Case have so much 'flex' in it?
How many hours were on the Case? Any idea on the capacity?
I'm not familiar with that model but is it an old commercial unit that was 'loose' when you bought it? )</font>
I dunno why the Case had so much flex in it. I just recall that it did and it didn't have the edges of the bucket applying more pressure when back-dragging my gravel driveway. Even though I was not in "float" mode, it did float rather nicely with the driveway.
It had just a bit over 5000 hours on it as I recall. I sold it a couple of years ago. And, yes, I've regretted doing so ever since. /forums/images/graemlins/blush.gif I guess in my situation with the Case 580, it was pretty worn out and loose, so it may not be the best for comparison. Sorry.

Highbeam,
Have fun bike'in, make sure you come back in one piece.
I was working on my grapple today and was playing around a little when I was done and I discovered that there is movement in the pistons as you push or pull on one side of the loader arm or the other. This may account for some of the play that I'm seeing. I had the bucket off and was pulling down with one hand while the other was feeling how much the piston was moving. Does any manufacturer us a flow divider for the cylinders on a loader? This would improve equal pressure to each cylinder, if indeed it is a factor. Anyhow, Thanks Bob for copying those threads over. I find this thread very interesting as each different person posts some results, like Dargo said, even if its of no interest to you how much a loader flexs, he's seeing some others loader hooks and receiver's.

My results:
KL130 Loader with two 6x6's.
Measured with a laser level (I had the level out playing with it to level a horseshoe pit)
With both wheels barely off the ground, 1.6" deflection.
My question: Is this good or bad?

The only thing that would concern me is due to the fact that your Kioti is the only one that greatly differs from the others. If yours indeed only has 1.6" drop and has VERY few hours on it, I'd be concerned about the loader design. My guess is that the loader design allows a reasonable amount of flex to prevent breaking with it's design. However, you seem to have the one Kioti that does not fit all the rest. Now I'm confused, and if it's true, concerned.
