  • Flag on Interlock Shaft

    I went into work at the center a couple days ago, when I came across a note from the guy working the previous night. Turns out one of the pinsetters would not drop the pins from the turret.

    So I go take a look and I notice the moving deck interlock blocking finger was in the down position. So I put the machine in 270 setting new pins to check the adjustment. When I take a look at the position of the flag on the interlock shaft in relationship to the hub on the moving deck cam follower. The flag was behind the hub instead of being in front of it. The flag was not flimsy in any way to allow it slide by the hub. The roll pins in the interlock shaft were all in place so the shaft could not slide around. I have no clue as to how the flag got behind the hub on that follower. Also, the 1st and 2nd ball light adjustment was way off.

    I get the adjustments fixed and the machine ran fine during a tournament squad. So I figure I got the kinks worked out. A few things worry me. How did the flag get behind the hub and can it happen again soon?

    So does anyone out there know what could have happened? Is there something else that I need to check? Even though the machine is running fine, you just never know.....

    Thanks for your help,

    Joey

    I've had this happen before. There is a chance that the interlock shaft itself is bent. Or maybe someone just messed with it and didn't know what they were doing!

      I seriously doubt that the night guy messed with because he's only been there for about 2 months. He knows very little and doesn't even know about the interlocks. He just knows the basic stuff get through little leagues and some nights. I've been paged and called a couple times for machine problem.

      I will check for a bent shaft my next day in.

      Thanks,

        I have seen this several times,usually it happens when a 1:1 is running retarded(bad keyway) when the correct adjustment is made at 0 degrees, the moving deck cam is still not on the high of the cam,so the adjustment is made even more to make flag bring finger up. in the end what happens is the flag is now in a too far rearword placement and the flag actully is too far rearward for hub to catch. Also if the "pin" project on the F.D.finger is bent or missing the Flag is able to fall too far rearward also.Hope that makes sence.

          Did I read this right...

          "So I put the machine in 270 setting new pins to check the adjustment. When I take a look at the position of the flag on the interlock shaft in relationship to the hub on the moving deck cam follower. The flag was behind the hub instead of being in front of it."

          You stated at 270 degrees setting new pins, the flag was behind the hub? The hub would be like 6 inches away from it in that position...because the moving deck cam follower is all the way back towards the 1:1. [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img]

            Sorry Steve, I messed up on what I said I did....

            When I adjusted the flag, I set the machine at 90 but I hold the deck lowering hook clear of the pin on the deck lift shaft. That way I would have room to work while made the adjustment with the moving deck cam follower in the most forward position. Of course, I made sure there were no pins on the pin deck. as this would defeat the purpose of hold the deck hold hook clear of the pin on the deck lift shaft.

            Sorry for my goof on the description.

            Thanks,

              Did the deck cable come off the previous night? Only way I can figure it is if the cable was off and the deck came up with the 7 pin bucket jamming into the flag before it could move forward of the hub. That would push it back enough.
