What Does This Tension Pully / Pully / Fan Drive Assembly Do?

The tensioner pulley maintains the correct tension on drive belts to prevent slipping and ensure efficient power transfer. The fan drive assembly regulates cooling fan speed — either mechanically via a viscous coupling or hydraulically — to match the engine cooling demand at any given load.

Possible Tension Pully / Pully / Fan Drive Assembly Problem Symptoms

If your machine is showing any of the following, a faulty tension pully / pully / fan drive assembly may be the cause:

  • Belt squealing or slipping despite the belt appearing undamaged
  • Tensioner pulley bearing making a grinding or rattling noise during operation
  • Engine overheating due to reduced or absent cooling fan speed
  • Excessive belt wear caused by the pulley not holding correct alignment or tension
