Detailed Product Description

This accessory drive belt idler pulley, part number 38065, is designed to maintain proper tension and alignment of the accessory drive belt in BMW 840Ci vehicles. The pulley is made from thermoplastic, providing a balance of strength and lightweight performance. With an outside diameter of 70 mm and a width of 28 mm, it fits precisely within the accessory drive belt system components. The smooth backside contact surface minimizes friction and wear on the belt, contributing to the longevity of the belt system. The pulley does not have flanges or grooves, which is consistent with its role as an idler pulley rather than a drive or tensioner pulley.
