Help needed finding a short Turnbuckle

[EddieWalker]

Here's my solution.

The pin extends out far enough that it should work as an anchor for an eye bolt. I bought a pair of them for $39.

Now I need to make an anchor on the attachment (grapple and then bucket) onto the QA.

My plan is to make a sort of U out of some 3/8's metal so that I can slide the threaded end of the eye bolt into it, and then tighten the nut.

This seems to be the simplist, strongest way that I can think of. Too many pieces and it loses strength and become dificult to take on and off. This should be easy to install and remove.

Thanks,
Eddie

A couple of thoughts. For a 10,000# WLL you're going to need a 1" eye bolt. BoltDepot has them and they have a 2" ID eye. A quick drawing of some brackets that could be welded up to anchor the nut end of an eye bolt or both ends of a standard bolt

Keith,

Thanks for the drawing, that's pretty much what I was thinking of in my brain. The 10,000 number was an estimate that I thought up out of thin air, but probably pretty close. I figure half of that for each eye bolt, which I think I'm pretty good with the ones I bought. The problem will be in the quality of my welds. If I get it right, I'm good, if not, they will snap off. It's happened before, so maybe I'll take the extra time to get it right the first time.

Here's a few more pictures of the QA. One thing that might add to my problem is the bracket that I created to make it work with my loader. I don't know, but I agree with everyone that this shouldn't be happening, or at least it doesn't happen in other applications.

I can't see anything that is wrong with the attachment or why it's coming apart. I can only guess it's a combination of things. Too much HP/Hydraulic power. Too much weight, and the design of the bracket.

Not quite sure what I'm looking at in pic #2, but looking at the rest, it all looks fine to me. That leaves the locking mechanism. Something is wrong with that. That has been the problem many times even with the smaller QA units on some of the compacts. Can you make your bucket come off every time that you go to use the backhoe, or does it only come off sometimes? Does your grapple come off if you were to drag it backwards? I'm sure that it must be something simple and we are just not seeing it. It would be a shame to loose the standard quick and easy usage of the QA. If some how the metal is flexing so that the pins are coming out, then that metal needs to be heaver. I just hate to see you loose the flexability of the QA.

Good luck

Brian,

Picture #2 is the same as #3, just another angle of that locking pin.

The grapple has only come off twice so far in about 12 to 14 hours of use. Of course, I'm also babying it and trying to put as little preasure on it as possible.

I agree that it's disapointing to lose the speed in the QA, but if it takes ten minutes to thrity minutes, I'm not sweating it because the flexibility to change attachments is still awesome!!!!!

Flexibility to change attachments is very nice indeed and your system will still be easier than if you still had pins.

Eddie, what if you put clip type pins, the pin with the round retaining snap thing like on the back of your tractor somewhere on the bottom of the quick attach pin where it protrudes through the bucket?

All you would have to do is to drill a hole in that pin (which is not holding anything anyway) and then pop one of those pins through there when you coupled up.

That would make it impossible for the QA pins to release, would be easy and cheap and quick.

You could also use bolts if you knocked those pins out too easily but if you got the black ones and cut the main leg a little shorter so the bail goes past the pin, they are much harder too lose.

See if this makes it clearer.

Apologies to Pat for using his picture, but visualize that the implement pin shown is the rod on your quick attach, and use this type of pin underneath to hold it from coming up and off. If you use the black high strength ones, and cut the leg a bit, they stay more secure in brush etc.

I am guessing something is flexing. It looks like it all fits together pretty tight.
