About the Cloyes Timing Chain Tensioner Product Line

The Cloyes Timing Chain Tensioner product line focuses on precision-engineered components that maintain proper timing chain tension to ensure engine valve train reliability. This line features hydraulic and spring tensioners designed to meet OEM specifications, providing consistent performance and reducing the risk of timing chain slack or failure. The 9-5659 model exemplifies this approach with its robust materials and activation pin design.

Detailed Product Description

This engine timing chain tensioner is constructed from a combination of nylon and aluminum, balancing strength and lightweight properties. The hydraulic and spring tensioner type automatically adjusts tension based on engine operation, eliminating the need for manual adjustment. Included with the tensioner is a shoe that guides the timing chain, helping to reduce wear and noise. The activation pin ensures the tensioner engages correctly during installation. With dimensions of 2.67 inches in length, 1.75 inches in width, and 2.60 inches in height, it fits securely using two mounting holes with precise inside diameters of 0.250 to 0.253 inches. This part does not include bolts, pulleys, gaskets, or seals, so those components must be sourced separately if needed.

Common Applications and Issues Addressed

• Maintains proper timing chain tension to prevent chain slack
• Reduces engine noise caused by loose timing chains
• Prevents premature wear of timing chain and sprockets
• Ensures accurate valve timing for optimal engine performance
• Addresses timing chain rattle and potential engine misfires

Installation Notes and Tips

Installation requires removal of the old timing chain tensioner and careful alignment of the new unit using the activation pin. Ensure the mounting holes align precisely with the engine block and that the shoe is properly seated to guide the timing chain. Since bolts and gaskets are not included, use OEM or compatible hardware and seals during installation. It is recommended to follow vehicle-specific service manuals for torque specifications and installation procedures.
