Fan Belt Tensioner — Spring-Loaded Automatic, Accessory Drive SKU: QT59215

This spring-loaded fan belt tensioner maintains steady belt tension so alternators, water pumps, fans, and other accessories run smoothly without slip or squeal. It’s a practical replacement when the original unit weakens or belts begin to wander and glaze.

Built for daily farm use, the arm and pivot hold alignment under vibration and dust, helping the belt track true and protecting bearings through long hours in the field.

• Automatic spring action to keep consistent belt grip and reduce noise
• Supports proper belt tracking for cooler, quieter operation
• Durable arm, pivot, and bushing design for long service life
• Bolt-on replacement that pairs with the specified idler pulley (verify before install)

Installation Tip: Safely de-tension the belt, remove the old assembly, clean the mounting boss, and torque fasteners to spec; re-route the belt per the diagram and confirm smooth, wobble-free tracking.

A dependable tensioner that restores quiet, reliable belt-drive performance through demanding seasons.
