Gates T41040 Engine Timing Belt Idler Pulley

Gates Timing Belt Idler Pulley T41040

The Gates T41040 is an engine timing belt idler pulley built for valve train service where smooth, stable belt routing matters. It is a steel, smooth-backside pulley with a 10 mm inside diameter, 35 mm width, and 60 mm outside diameter for select Hyundai and Kia timing belt applications.

Gates PowerGrip idler pulleys are offered as fixed idlers or as replacements for a tensioner bracket, with metallic or plastic construction depending on the application. This T41040 pulley uses a smooth contact surface and steel construction for timing belt systems that require backside belt contact.
