110 tlb thumb question?

[murphy1244]

his is bending the arm.

I thought just leaving it off may have been the best in the other case. Your setup seems to support the stop is a bad idea on the 110 thumb set up. How many times have you used the thumb? It tagging from time to time would not concern me.

No, it does not appear to be bending the arm. I have only had the 110 for about 2 months and have used the thumb a couple times.

in this photo you can see that someone closed the arm with the thumb opened and did some damage

Whoa... really??

I thought that maybe I'd "overreacted" and concluded that the issue was really a matter of misplaced "concern". So, I went back and carefully looked over the OP's initial photos. Nah, I didn't overreact; the problem is really misplaced concern!

You might wanna go back and revisit those pictures as well.

Look at the front plate of the dipper arm. Please note the concave surface and the inside gap between the dipper and the contact/wear plate. During the final welding and construction of the dipper arm, the surface of the arm developed a "normal" concave.

I would bet "dollars to donuts" that virtually every boom arm and dipper arm you'd care to inspect - irregardless of manufacturer - has some distortion. Every sheet of flat steel or plate steel that I've ever looked at has a measure of warpage. Before... before it's ever been welded! A perfectly flat surface or perfectly square dimension is a fantasy.

I'd like to see photos of straight edge measurements taken along the face of the boom arm and dipperstick ALL THE WAY to the thumb - beginning at the bottom of the boom arm.

Take it easy fish, I was just doing a comparison to Doc's dipper stick. What do you think of his photo's???

Was this done with an OEM JD thumb like showed in the first post on this thread?

To me it looks more like marks made by the bucket teeth.

Ok... here's when I'll have to admit to making a dumb @ss move with my 110 backhoe! 'Cause I've got a dent along the edge of my boom arm - just like that!!!

If you leave the stabilizers in the up position and swing the hoe from side to side.... well, the backhoe is NOT designed to do that! And those darn stabilizer feet will absolutely crimp and roll it over; that 1/2" (might be 5/8") thick plate steel! Aaarrggh!

I only did it on one side, though... that was enough. 'Course, if you were in a full-blown swing motion - it would/is very hard to stop that motion with those legs up - the whole back end of the tractor is swaying! And you could crimp both edges.

Based on our JD 310 hoe I do not think JD would design anything that would interfere with another part of the hoe. The bucket teeth (longer after market teeth) gets close but still clears. Our weld on manual aftermarket thumb will not interfere in any possible setting from max to closed positions. We tacked it on then tested in each possible position before proceeding with the mounting process.

Now our hoe bucket was made for another model/brand machine and someone cut off the old bucket below the pins and welded on the current bucket and got a very slight bit of angle in the process so the thumb teeth do not always mesh well with the bucket teeth but that is only an issue when closing the bucket to travel.
