⚙️ Key Features

• 0.212 kg
• For the starter and auxiliary gear-drive engagement assembly
• Listed for 27 applications across D and TAD series engines

🔌 Function

Engages the flywheel ring gear when the starter is operated, transmitting cranking torque to turn the engine over.

⚠️ Common Signs of Failure

• Harsh grinding or screeching when the starter is operated
• Starter spinning without turning the engine
• Starter engaging but slipping under compression
• Pinion teeth found chipped, hooked or worn to a point on strip-down
• Metal filings and tooth debris found in the bellhousing

🛠️ Service Notes

• Inspect the flywheel ring gear before fitting a new pinion - a damaged pinion almost always means damaged ring-gear teeth, and a new pinion will fail quickly against them
• Check the starter engagement and the battery and cables at the same time; slow cranking from a weak supply chews pinions
