Slingshot kicker arm sticks or kicks weakly on a 1950s Gottlieb woodrail.

1950s Gottlieb woodrail slingshot binds

Cause: On these games the plunger drives the T-shaped kicker directly through a hardened roll pin. The unhardened T mech wears a groove at the pin slot, and the pin binds.

Checks

• Inspect the roll pin slot in the T kicker for a worn groove.

Fix

• Replace the whole mechanism with the later (late 1950s) plunger-and-link slingshot assembly.

Systems

• Electro-mechanical
