Starter Pinion 6 Volt

Voltage

6 Volt

Number of teeth

10 teeth

Application

Starter motor MZ-4113

Type

Bendix drive assembly

Features

  • 10-tooth pinion for 97-tooth flywheel ring gear
  • Complete with return spring
  • Suitable for 6 volt and 12 volt conversions
  • Left-hand helical thread
  • Ready for fitting on armature shaft

★ Standard replacement part for 6 volt starter motors on classic military and civilian jeeps. The Bendix drive provides automatic engagement and disengagement during starting.

Application

Fits starter motors type MZ-4113 and A1245 with 97-tooth flywheel. This starter configuration was used on the vehicles listed in the product categories with 6 volt electrical systems.

Installation notes

Before fitting, check that the pinion slides freely over the armature shaft and returns under spring tension. Clean the helical thread thoroughly but do not grease it – dirt and oil attract each other and cause malfunctions. During fitting, the pinion must engage correctly with the flywheel ring gear.

Compatibility

Specific to starter motors with 10-tooth pinion and 97-tooth flywheel. NOT compatible with later 9-tooth systems (124-tooth flywheel) as used on early CJ-3A and M38 models. Check the starter type (MZ-4113) before ordering.

Historical context

The Bendix drive was used during WWII on military jeeps and remained standard on early civilian CJ models. The system uses a helical thread that pushes the pinion forward when the starter motor rotates.
