Fan Belt Tensioner — Spring-Loaded Automatic, Replacement Assembly SKU: QT59166R

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

Built for everyday farm work, the tensioner arm and pivot maintain alignment through vibration and dust, helping the belt track true and protecting bearings across long hours in the field.

• Automatic spring action maintains consistent belt grip to reduce slip and noise
• Rigid arm and pivot design to hold alignment for quieter, cooler-running drives
• Durable construction for long service life in harsh agricultural environments
• Bolt-on replacement that integrates with the matching idler pulley where equipped (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-ready solution that restores quiet, reliable belt-drive performance through demanding seasons.
