Fan Belt Tensioner — Spring-Loaded Automatic SKU: QT404858

This spring-loaded fan belt tensioner keeps proper tension on the drive belt so accessories like the alternator, water pump, and fan run smoothly without squeal or slip. It’s a practical replacement when belts wander, glaze, or the original tensioner loses spring force.

Built for everyday farm work, the tensioner arm and pivot are designed to hold alignment under vibration and dust, helping the belt track true and protecting bearings across long days in the field.

• Automatic spring tension maintains steady belt grip and reduces slip
• Helps keep belt alignment true for quieter, cooler-running drives
• Durable arm, pivot, and bushing design for long service life
• Service-friendly bolt-on replacement; accepts matching idler pulley (verify before install)

Installation Tip: De-tension the belt safely, remove the old assembly, clean the mounting boss, and torque fasteners to spec; re-route the belt per the diagram and verify smooth, wobble-free pulley tracking before returning to service.

A dependable, farmer-friendly solution that restores quiet, reliable belt drive performance across demanding seasons.
