Quick Attach Broken AGAIN!!

[sugarmaple]

Verrry interesting! Neither of the local dealers or anyone else I discussed this problem with, had ever heard of it. Certainly neither had heard of the kit. I first started having a problem with the Anbo grapple rake and after some head scratching, decided to weld a piece of 1/2 barstock to the QA plate at the location that the pin engages the slot therby allowing the pin to carry the load at a thicker cross section than previously when the spring compressed. Observation told me that the load acting against the pin caused the spring to compress allowing the pin in turn to ride up and out of its engagement slot. Sounds like the fix discussed above accomplishes the same thing, more elegantly limiting the back travel of the pin and spring compression. I broke 3 pins before devising this fix and have now done the forks, bucket and grapple. Having heavy loads bearing on such a thin cross section as the tip of the pin is a failure waiting to happen. Now my pins are broken off 1/4" up, but no more falling out of the slot back dragging and whathaveyou.

I wonder if this problem is due to uneven specification of the QA plate from manufacturer to manufacturer? Or is it that a QA mount is not meant to have loads imposed from the rear (hardly seems likely).

Hugh,

That 3rd picture of yours doesn't look right. I think the main surface of your QA should be seated on the main surface of the implement and yours has a gap there. If it were seated, your locking pin would be penetrating the implement more. Is there a gap between the two main surfaces on the left side as well?

If my loader valve weren't broken, I'd put the bucket back on mine to see how it mates.
