- Durable Drive Surface: Built to withstand continuous belt friction and load in demanding engine accessory drive applications.
The 1136603600 crankshaft pully zaxis 450 6wg1 ensures consistent belt tension and power transfer to engine accessories on the ZAXIS 450 6WG1.
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
