  • Bowling balls between the lift rods and the impact bar

    If I could eliminate the balls getting stuck between the lift rods and the impact bar my nights would be so much more productive on getting other problems worked on. Any ideas on how to get rid of this problem. My machines are jet backs but running at A speed. I dont know what else to do. UGH

    Just a few things to check...

    ---Are you using ball wheel kickers?? If so what type?

    ---How often do you clean the ball wheels?

    ---Have you checked the height of the rear clamping plate of the pit frame
    in relationship to the ball wheel?. (Pit Conveyor ADJ #23 Page 3-28 in SM)
    Go with what works and not what the book says.

      Check the adjustment between the height of the ball wheel and pit conveyor. You want to shim the pit conveyor up high enough to keep the ball from bouncing back out of the back of the pit, but low enough that the back edge of the pit doesn't contact the ball when the pit conveyor hits it's fully rearward position. I think what you are seeing is the ball wheel, or ball wheel kicker strip contact the ball too early, resulting in the ball being pushed towards the front lift rod too early. the balls start getting jammed between the lift rods and the ball cushion, or under the front lift rod elbow.

        If calls are resent check your mouse-trap may be to sensitive or sloppy do to ware [ sample adjust it ]

        If pit cushion gets tripped to early [ by A pin ] ball can hit front lift rod and bend back out of adjustment

          Could be something as simple as deteriorated pit mounts. Either style...rubber or urethane...can cause the pit to be too low causing the ball to be grabbed too soon. If you think the pit is too low...start by being sure your pit mounts are in good shape.

            Thanks guys. I believe the pit conveyors are way to low. There is maybe an 1/8 of an inch difference without the kicker strips coming into play. Im gonna raise a pair or two to see how it works. Thanks alot.
