Full model list at the end of this description.

⚙️ Key Features

  • For the servo pump drive when no air compressor is fitted
  • Engine group gear, 0.907 kg
  • Supersedes part number 22492480
  • Listed for 23 applications across TAD, D and TADH series engines

🔌 Function

Drives the servo pump from the engine's timing gear train on installations built without an air compressor, taking the place the compressor drive would otherwise occupy.

⚠️ Common Signs of Failure

  • Whine or growl from the gear train that rises and falls with engine speed
  • Steering assistance weak or intermittent as the pump drive wears
  • Metallic glitter in the oil or debris on the sump magnet
  • Teeth chipped, pitted or worn to a step, with excessive backlash, once the cover is off

🛠️ Service Notes

  • This gear is specific to engines without an air compressor: confirm the engine's build before ordering
  • It supersedes 22492480, so an engine listed with the earlier number takes this gear
  • Check the mating gears and the pump drive shaft and bearing for matching wear before fitting only the gear
