Pulley Tensioner — Spring-Loaded Automatic Belt Drive Tensioner SKU: QT580023

This spring-loaded pulley 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 belts wander, glaze, or the original tensioner loses spring force.

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

• Automatic spring action keeps consistent belt grip to reduce slip and noise
• Helps maintain proper belt tracking for cooler, quieter accessory drive
• Durable arm, pivot, and bushing design for long service life
• Service-friendly bolt-on replacement; mates 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 verify smooth, wobble-free tracking before returning to service.

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