⚙️ Key Features

• 3.279 kg
• Supersedes 420067
• 78 applications across six engine series

🔌 Function

Gives the starter pinion the toothed rim to engage so the engine can be turned over.

⚠️ Common Signs of Failure

• Harsh grinding or clatter as the starter engages
• Starter spinning without turning the engine
• Teeth chipped, hooked or broken away in a patch
• Engine failing to start only when it stops at a particular position
• Tooth ends peened over from repeated poor engagement

🛠️ Service Notes

• Ring gear 420794 is the other ring gear here at 3.266 kg, only 14 grams away, but it is the version for the Voith gear box — weight cannot separate them, so order on the gear box
• Check the starter pinion and its engagement travel at the same time, or the new ring gear will damage in the same place
