Part number 9-6240 is listed for a wide range of Mercedes-Benz models, including SL550, S550, and E550 applications. If you are servicing a Mercedes-Benz timing system, this tensioner is specified for lower-position use and matches the application details shown below.

Key Features

Engine timing chain tensioner for lower timing system service
Uses spring tension or hydraulic pressure depending on application design
Part number 9-6240 for application matching
Fits multiple Mercedes-Benz V8 and AMG applications
Brand Line focuses on timing system components

Detailed Description

Cloyes 9-6240 is an engine timing chain tensioner designed for Mercedes-Benz vehicles with lower timing chain service requirements. The tensioner maintains chain tension to support proper timing system operation, and Cloyes notes that tensioner design may use spring force or hydraulic pressure depending on the engine application. For timing system service, Cloyes recommends replacing the chain, tensioners, guides, and sprockets together to maintain system integrity. This part cross-references Mercedes-Benz OE numbers 2780500611 and 278050061164 for the same application.

Compatible with Mercedes-Benz SL550, S550, E550, CLS550, GL550, ML550, and related AMG models listed in the fitment data, this timing chain tensioner is a fitment-specific replacement for lower-position applications. Use part number 9-6240 to confirm the correct timing component for your Mercedes-Benz engine service.

What It Helps Address

Timing chain slack in the lower timing system
Noise caused by insufficient chain tension
Timing instability during engine operation
Wear-related service needs in the timing assembly
Incorrect replacement selection during timing repair

Installation Notes and Tips

Verify engine code and fitment before installation, since this part is application-specific. Cloyes recommends replacing the timing chain, guides, and sprockets at the same time as the tensioner during timing service. Confirm lower-position application details and match part number 9-6240 to the vehicle’s timing system requirements.

Quality Assurance

Cloyes has supplied automotive timing system components since 1921 and states that its timing products are backed by an industry-leading warranty and technical support. Part number 9-6240 reflects Cloyes timing-system expertise for Mercedes-Benz service applications.

This part fits 99 vehicles
