Where this component fits
These supporting engine components are separate from injection-pump or injector service. Correct selection still begins with the specific engine or equipment configuration.
Identify the correct part before ordering
Provide engine model and the tensioner or bracket part number, with an image of the pulley arrangement.
Include the engine model, mounting and electrical or coolant connections as relevant, plus the original component number. One engine family may have multiple accessory variants.
Choose the correct replacement assembly
Inspect belt, idler and accessory drag when investigating a repeated tensioner issue.
Check physical mounting, configuration, power or cooling connection as applicable. DCT will confirm whether the specified accessory is currently available rather than infer fitment from the product family.
