Cloyes 9-6055 Engine Timing Chain Tensioner - Right

Cloyes Timing Chain Tensioner 9-6055

The Cloyes 9-6055 timing chain tensioner is built for engine timing service where chain control matters. It uses hydraulic and spring tensioning with an activation pin, helping maintain proper chain tension in the right-side timing drive on select Ford and Lincoln applications.

Cloyes timing systems have been a trusted name since 1921, and the 9-6055 reflects that focus with a metal construction, aluminum housing, and a gray finish. This part is a direct-fit timing chain tensioner for service work on the 2017-2021 Ford F-150, 2018-2021 Ford Expedition, and 2018-2021 Lincoln Navigator, right side.

Product Details

The Cloyes 9-6055 is an engine timing chain tensioner engineered to maintain proper chain tension during operation. By helping keep the timing chain properly loaded, it supports stable valve timing and consistent engine operation. Cloyes recommends replacing the chain, tensioners, guides, and sprockets together during timing service to preserve total timing system integrity. This part cross-references Ford HL3Z6L266C for the same application.

What It Helps Address

• Timing chain slack on the right side of the engine
• Noise caused by worn or weak chain tension control
• Timing system wear during high-mileage service intervals
• Valve timing inconsistency related to chain control issues
• Service replacement for a worn timing chain tensioner

Installation Notes

Install on the right side only for the listed applications. Verify the mounting hole count and diameter before installation, and follow factory timing procedures during service. Because no gasket, seal, bolts, or hardware are included, reuse or source the required installation components separately as specified by the repair procedure. For timing system repairs on the Ford F-150, Ford Expedition, and Lincoln Navigator, inspect the chain, guides, and sprockets at the same time.

Quality Assurance

Cloyes has supplied timing system components since 1921 and backs its products with technical support and an industry-leading warranty. The 9-6055 is built for timing service where accurate chain tension is required.
