The shooter rod end is mushroomed or burred, or its rubber tip is missing.
Shooter rod tip damaged or rubber tip missing
Cause: The bare metal rod has been hitting the ball.
Checks
- Look at the rod end and rubber tip.
Fix
- File or grind the rod end smooth.
- Fit a new rubber shooter tip so metal never strikes the ball, which would damage the ball and then the playfield.
- Clean the housing bushing with alcohol and replace it if damaged.
