• Timing chain noise or rattling from the engine
• Worn or damaged chain guides
• Weak or failing timing chain tensioner
• Excessive timing chain stretch
• Service replacement during engine timing repair

Installation Notes

Verify engine code and timing system configuration before installation, since timing components must match the exact application. Replace worn timing components as a complete set when possible, and follow factory timing procedures to maintain correct camshaft and crankshaft synchronization. Because gaskets and drive sprockets are not included, confirm whether additional parts are required for the repair before beginning service.

Quality Assurance

INA timing chain kits are built to include the essential components needed for a proper timing repair, with chain guides and a tensioner included in this kit. The manufacturer also notes that certain INA timing kits may include a high-performance chain additive formulated for reduced friction during break-in and lower run-in wear, depending on application.
