  • Falling pin

    HELP! I have a machine that keeps knocking over the #1 pin. It's happening when a full rack is setting down, and the cell just doesn't clear the bottom of the pin, thus pulling it back. it's happening about every 10 racks. I've had two mechanics look at this, and they can't figure it out. I have full leagues coming in today, and this looks like a nightmare. AMF 82-70's. Any help would be greatly appreciated!

    Re: Falling pin

    Have you tried changing out the respot cell itself? That would be the obvious solution... and I'm a keen observer of the obvious.

      have you adjusted the carb link?,sounds like you would be better setting up the re-spot cells from scratch.

        1st Check the cup width.
        2nd check the table height


        If the cup width is ok and is about the same as ALL the other cups. Then try lowering the table 1/2 turn.
        Just watch that the cups dont start hitting the top of the pins on respot.

        This would be the first 2 things I'd try. As they are the most simple.

        Then I'd start checking all the bushings & Bearings.

          Thanks! I'll try lowering the table first. We've replaced the cell three times-width is ok. Changed the bearings in the table legs, checked the clevis, replaced all the pins themselves. We've got the cell tilted back about as far as it will go- if we straighten it out, it never lets go of the pin at all.

            Take the cup liners out.

              Have you checked the table to see if it's level ?

              Starting to sound like it maybe tilted towards the back. Making the back end of the table lower then the front. You might want to check it to see if you have the same height from the pin deck to the table in the front as you have in the back.

              It dont take much of a height difference to cause problems.

                  <font size="2" face="Verdana, Helvetica, sans-serif">Is the pin (or spotting cup) hitting the respot cell itself (the fingers), or is the pin getting caught in the spotting cup? You state that the cell isn't clearing the bottom of the pin... do you mean that the spotting cup isn't clearing the bottom of the pin? Clarifying this would help in finding the solution to your problem.

                    Make sure the sweep isnt hitting the headpin as it recycles if so youll want to adjust your sweep cam.Just a thought.ooops guess I read that wrong its cathching on the cell or the cup itself ?Youve changed the cell what about the cup itself?

                      Re: Falling pin

                      when you say cell,do you mean cup? or is the pin getting lifted out of the cup by a finger? sounds like a simple finger cell adjustment to me...

                        I read it as the cup was pulling back on the bottom of the pin. But after I re-read His text. I'm not sure if he's meaning the cup or a finger off the re-spot cell.

                        More info please.

                          Sorry guys, I mean cup. Thanks for the lowering of the table advice- it worked! the #1 pin didn't fall over once tonight, but now the #7 pin has taken it's place. not every cycle, but enough to cause problems (About every 10 cycles.). This started happening after a nasty pin jam in the #2 pin area- could something be twisted, broken, vexed or cracked?

                            You may have to flag the table...and get it level side to side and front to back. A flagged and level table lets you adjust cups so they are consistent with each other so when you adjust the bubble the pins set the same....also check your bushings in the connecting rod(lighting rod).

                            There are several great procedures posted on the site for step by step table adjustment. I think King and Kat both have posted them here before.....

                              Yeah, dont forget the tie link (lightning rod) and put some TENSION on those cups, soldier! Broken yoke springs or springs with no pressure can lead to sloptastic spotting action. Good luck.
                              The impossible often has a kind of integrity to it which the merely improbable lacks.
