How to test your target assembly:
Coin in a 2 player game and allow it to run
All targets should present in round 2, final score should be 0-0
Solutions to try:
1) General Target check:
2) Ensure O-Ring Tire and arm are clean and free of dust and oil (use air duster and/or mild
cleaner)
3) Ensure motor wheel is positioned correctly on motor shaft (slight clearance from screw
heads) 1/16 max between head of screw to back of the pulley.
4) Ensure Motor wheel set screw is tightened on shaft flat
5) Spring washer specific:
Replace with tall spring (MU750-0160, Ø1.103
O.D.) or double up on the spring.
Position the wheel so that the head of the
screw will not rub against the wheel. The use
of blue Loctite to secure the grub screw is
recommended.
