Belt Tensioner Assembly for Fan and Accessory Drive Systems SKU: QT44001

When belts start squealing or slipping, you're dealing with a failed tensioner that can lead to a dead alternator, overheating engine, or failed hydraulic system stranding you in the field. This belt tensioner assembly restores proper automatic tension control, preventing premature belt wear and sudden failures that happen at the worst possible times.

Why Automatic Tension Matters

• Calibrated internal springs automatically maintain optimal belt tension throughout service life
• Prevents belt slipping without over-tensioning that causes premature bearing failure in accessories
• Sealed construction handles engine compartment heat, vibration, and contamination
• Consistent tension across varying loads and speeds that manual adjustments cannot provide

If you've been experiencing frequent belt failures or premature alternator bearing problems, this new tensioner will solve those issues by maintaining proper belt tension automatically. With 55 years of farm equipment expertise, S&H Parts helps you get the right solution the first time.
