Overview

Take the wobble out of the belt drive with this Belt Idler Pulley Assembly distributed by FleetPro Parts & Tires. On a Volvo VNL, the idler is the quiet pulley that guides the belt around its path and keeps the correct wrap on everything the belt turns. It is also the part nobody looks at until the bearing goes rough, and a rough idler announces itself as belt flutter, a squeal that will not tune out, and a belt that wears out in a fraction of its normal life. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

A Smooth Belt Path: The Volvo VNL Idler Pulley Advantage

This is a complete idler pulley assembly, not a bare bearing, so the pulley face and its bearing arrive matched and ready to bolt on. Replacing the whole unit is the difference between a repair that lasts and one that puts a new belt on a used bearing. At just 2.58 lbs it handles easily at the engine, and it ships in a compact 8 x 5.875 x 4 in box.

Manufactured by Automann to Fleet Standard specification, every unit is new and backed by the 1-Year FleetPro Warranty. At FleetPro Parts & Tires, we would rather you replace the idler while the belt is already off than chase the same noise twice. This assembly is a direct replacement for highly searched Volvo numbers including 20521447, 21153968, 21393207 and 21766717.
