  • pins falling through

    NEW PROBLEM!!! what's new...

    When the second set of pins lands on top on the table, they're pushing the first set through the shuttle... this is happening EVERY time on the 2 and 8 and a lot on a few other spots... Any ideas??

    do the pins center correctly in the bin?

    I would start with making sure you dont have any broken bin bumpers or shuttle tubes. Then make sure the shuttle is centered under the bins. (this is easy to achieve by removing the worless frame counter, and filing it in the round recptical. Then you can drop the back of the shuttle and bend it in the direction it needs to be. after done, make sure you tighten the clamp studs on the front)

    Then adjust the shuttle back (with the main drive link rod end) until you get proper shutteling. I would go 2 to 3 half turns at a time, until the problem disapears. If you go too far, it will start withholding pins.

    Good luck.

      As a test, you can hook a spring preferably a belt idler spring that drives the rear roller. Hook it to one of the holes on the strap on the rear of the shuttle, then hook the other end to the angle where the dist. is mounted...might have to use a little twist of bailing wire. This will snap the shuttle back quickly and will verify if the shuttle operator is working correctly. If it works, then follow JimDorsin's procedure.
      Yeah but, We've always done it that way.

        Also you could check to see if your shuttle tubes are bent creating much to wide a gap allowing the pins to just fall through, one thing i do its probably not absolutely required but it sure cant hurt, is i fit the shuttle with bin straps on every pin all but the head pin i find it makes for a VERY strong shuttle assy. Also what i do is when checking the height adjustment at the rear of the shuttle i dont sit the tool on the rear tube i sit it on the bolt head that holds the shuttle tube bracket if you get what i mean. It helps to get the shuttle assy a bit lower to the cups stopping double pin feeds.

          Just recently had this same problem.Put in shuttle straps where their wasn't any and as doing found shuttle was bent out where pins fall thru,replace worn pin holders,and adjust the shuttle drive rod.

            it may be the shullte drive rod needs serviced and the compression spring checked.This should be 6 inches when not in a compressed state. if it is 5 1/2" it is needing to be replaced. very often a simple strip down and check is all that is required.

              Try a Zot Bin Holder on the eight pin. If you like' may need more elsewhwere!

                hi Guys,I'm new and would like to introduce myself.My first name is Dave and all though I'm fairly new to bowl-tech, I'm not new in the business.I have been working on AMF machines for going on 33yrs...Worked on 30's for 4yrs. the rest on 70's.Even did a short stint working on brand X... i have found when everything seems to be order with the shuttle assy.and U still get a double shuttling problem occasionlly,I change the two lower bin bumpers out and use the thicker ones that go on the rear filler plate that the kicker assy. rests on.Some how this just works or at least it works for me most of the time.Can't swear it will work all the time ,but what the hel its quick, cheap, fast and does the trick.I guess by changing the angle which the pin rests in the bin is what makes the difference.I'm no expert,but I do know a little 'bout 70's...

                People tell me I'm indecisive, but I just don't know...

                  This is how I fix double shuttling.

                    otto It sounds to me like if this is a new problem then it may have been caused by a table jam and it has raised up the shuttle and bin assemblies to where they are almost or are off the support pins in the front of the machine. If your bins get raised right there they will alow alot of pins through. If this is not your problem then try every thing that was atated before. If this is your problem then simply put your bins back on the support pins and that will lower you bins and shuttle back to the right hight.
