Product Details

DriveAlign Premium OE Pulley 36743 is engineered for accessory drive belt systems where correct pulley alignment, belt tracking, and smooth rotation matter. The 70 mm outside diameter, 23 mm width, and 17 mm bearing bore inside diameter support a direct-fit replacement approach for the listed Nissan and Suzuki applications. This Gates pulley cross-references Continental 50072 and Four Seasons 45078 for the same application.

For Nissan Frontier, Nissan X-Trail, Nissan Rogue, and Suzuki Equator service, this pulley is a practical replacement when the original idler pulley shows wear, noise, or tracking issues. The flanged, 6-groove design matches V-ribbed belt routing used in the accessory drive belt system.
