BALL DOOR ADJUSTMENT
The ball doors must be positioned in the ball door openings so that they don’t rub on the ball door
protector ring or transport band, are level with each other, and have a minimal gap at the top of the
ball door shaft. This will allow for complete closing of the ball doors and allow light weight balls to
exit with minimum interference. Having the doors at the same height relative to each other prevents
the doors from binding on each other as they open and close. A collar on the ball door shaft is used to
provide equal spacing at the top and bottom of the ball door. Refer to Figure 5-12 .

1. Adjust the collar by loosening the set screw and retightening when the door is centered as
desired.
2. After adjusting or reinstalling a door, check to see if it is level with the other lane’s ball door
and that both doors can open and close without any interference.
