Gates T42138 Engine Timing Belt Idler Pulley - Lower
Gates Timing Belt Idler Pulley T42138
The Gates T42138 timing belt idler pulley is a steel, smooth-backside pulley built for the engine valve train. It is a lower timing belt pulley for select Audi applications, including Audi A4, A4 Quattro, A6, and A6 Quattro models from 2002-2006.
Key Features
- Steel construction for timing system durability
- Smooth/backside contact surface for belt routing
- Flanged end for secure belt tracking
- Inside diameter: 10
- Outside diameter: 59
- Width: 37
- Contents: pulley only
Product Details
Gates Timing Belt Pulley T42138 is part of the Gates PowerGrip idler pulley line, which includes fixed idlers and replacement pulleys for tensioner bracket applications. This pulley uses a smooth backside contact surface and steel construction to support timing belt routing in the lower position. It cross-references URO 06C109244C for the same application. Fits 2002-2006 Audi A4 Quattro, lower; fits 2002-2005 Audi A4, lower; fits 2002-2004 Audi A6, lower; fits 2002-2004 Audi A6 Quattro, lower.
Common Uses
- Replacing a worn or noisy lower timing belt idler pulley
- Restoring proper timing belt routing on interference-engine Audi applications
- Addressing belt tracking issues caused by pulley wear
- Correcting timing system noise from a damaged pulley bearing or surface
- Supporting maintenance on the engine valve train timing drive
Installation Notes
Verify the lower pulley position, belt path, and OE reference before installation. Inspect the timing belt, tensioner, and adjacent idlers for wear while servicing the timing system. Confirm fitment by year, model, and engine configuration on 2002-2006 Audi A4 and A4 Quattro, plus 2002-2004 Audi A6 and A6 Quattro applications.
Quality Assurance
Gates PowerGrip idler pulleys are offered as OE-style timing components with fixed-idler and tensioner-bracket replacement coverage in the product line. The T42138 is built with a steel body and flanged design to meet timing system service requirements.
