Product Details

Gates Timing Belt Pulley line components are engineered for engine timing service, including fixed idlers and replacement pulleys used in tensioner bracket assemblies. The T41227 follows that application type with a smooth, steel contact surface and flanged design to support proper timing belt routing in select Audi A4, A4 Quattro, A6, A6 Quattro, S4, RS4, Allroad Quattro, and Volkswagen Passat models. This part number, T41227, is commonly referenced for timing belt service on interference-engine applications where pulley condition directly affects belt alignment and engine timing integrity.

This part cross-references URO 078109244H for the same application.
