🔌 Function

Transmits drive from one shaft to another through meshing teeth, setting the speed and torque relationship between them.

⚠️ Common Signs of Failure

  • Whine or growl that changes with load
  • Teeth chipped, pitted or worn to a point
  • Metal glitter in the oil or on the drain magnet
  • Backlash felt to be excessive when the drive is rocked
  • Bore or keyway worn so the gear moves on its shaft

🛠️ Service Notes

  • Inspect the meshing gear and the bearings at the same time — a damaged tooth flank rarely happens alone
  • Renew the oil and clean the housing before reassembly so no debris is carried over
