⚙️ Key Features

  • Engine group timing and drive gear, 0.773 kg
  • Listed for 20 applications across TAD, D and TADH series engines

🔌 Function

Transmits drive within the engine's timing gear train, passing rotation between the crankshaft gear and a driven component at the designed ratio and phase.

⚠️ Common Signs of Failure

  • Gear whine or a rattle from the timing end that tracks engine speed
  • Noise that changes when the driven accessory is loaded
  • Fine metallic debris in the oil or on the sump magnet
  • Pitted, chipped or unevenly worn teeth and slack backlash found on inspection

🛠️ Service Notes

  • Three gears share this number group: 21735434 at 0.538 kg and 21735437 at 0.907 kg, the latter specific to engines without an air compressor, so order by number
  • Renew a worn gear together with the gear it meshes against, as a damaged tooth form quickly ruins a new partner
