PINION PROTRUSION LENGTH ADJUSTMENT

Pinion-protrusion adjustment

1
With pinion driven out by magnetic switch, push pinion back to remove slack and measure clearance "ℓ" between the front edge of the pinion and the pinion stopper. Clearance "ℓ": refer to S.D.S.
2
Not in the specified value → Adjust by adjusting plate.
