Idler Belt Pulley — Tensioner Pulley for Accessory Drive SKU: QT59831

This idler belt pulley works as the tensioner pulley in the accessory drive, guiding the belt so it tracks true with steady grip. It’s a practical replacement when the original pulley or bearing wears out and belts begin to squeal, slip, or wander.

Built for daily farm use, the pulley runs true with a smooth bearing and a durable finish that stands up to dust and vibration—helping protect alternator, water pump, and other belt-driven components.

• Replacement tensioner/idler pulley to maintain proper belt tracking
• Smooth-running bearing for quiet operation and long service life
• Sturdy construction and corrosion-resistant finish for field conditions
• Straightforward fitment for common accessory belt layouts (verify routing before install)

Installation Tip: Safely de-tension the belt, remove the old pulley, clean the mounting boss, then install and torque hardware evenly; re-route the belt per the diagram and spin the pulley by hand to confirm smooth, wobble-free rotation.

A dependable replacement pulley that keeps your belt drive quiet, tight, and working the way it should.
