pull the belt to the side and loosen the 2 Allen
set screws that hold the drive roller to the motor
shaft.

LOOSEN THESE SCREWS
13. Remove the 4 adjusting bolts on both ends of
the assembly, separate the end brackets and
remove the belt.
14. RE-ASSEMBLE IN THE REVERSE ORDER.
15. NOTE: TIGHTEN THE SCREWS THAT HOLD
THE MOTOR TO THE ASSEMBLY JUST TIGHT
ENOUGH TO JUST SQUEEZE THE GASKET
MATERIAL. OVER TIGHTENING COULD
CAUSE SHAFT MIS-ALIGNMENT AND / OR
EXCESSIVE MOTOR NOISE.
6. FOLLOW THE DUCK BELT ADJUSTMENT
PROCEDURES AT THE END OF THIS SEC-
TION.
DUCK BELT ADJUSTMENT
1.
PRELIMINARY ADJUSTMENT
- Loosen the 4
bolts that hold the duck belt assembly to the
cabinet. They should be loose enough that the
entire unit can be slid back and forth easily.
2. Loosen the eight bolts that are used to tighten
the belt. There are 4 bolts on each end.
3. Loosen the bolts that secure the roller bearings
to the assembly, and re-tighten them at the mid-
point of their adjustment slots.
4. Tighten the bolts on the idler roller end of the
assembly about ½" from the innermost position.
5. Pull on the motor end of the assembly to remove
slack from the belt.
6. NOTE: WHEN THE BELT SLACK IS AD-
JUSTED PROPERLY THERE WILL BE NO
MORE THAN 2 INCHES OF DROOP ON THE
BOTTOM SIDE OF THE BELT.
7. If there is more than 2 inches, retighten the belt.
8.
FINAL ADJUSTMENT
- Start a game and notice
how the belt track.
9. If the belt tracks to one particular side, loosen
the bolts that adjust the roller bearings and move
the roller in or out for proper tracking. This can
be done during a game when the belt is moving,
if done carefully.
10. It may be necessary to adjust both ends once or
twice to get the optimum tracking.
