Detailed Description

INA timing chain kits are assembled to support accurate timing service on engines that rely on a chain-driven camshaft system. For the listed applications, the kit is built to address timing wear with the core components needed for a proper repair, and some versions include cam and crank sprockets where required by the engine design. On select kits, INA also uses a specially formulated chain additive supplied for Schaeffler by Liqui Moly to reduce friction during initial operation and limit run-in wear.

Compatible vehicle coverage includes 1991-1995 Buick LeSabre, Park Avenue, Regal, and Riviera; 1991 Buick Reatta; 1991-1995 Pontiac Bonneville; 1992-1994 Chevrolet Lumina APV; 1992-1994 Pontiac Trans Sport; and 1991-1994 Oldsmobile 88, 98, and Delta 88. Search terms such as Buick LeSabre timing chain kit, Pontiac Bonneville engine timing set, and Chevrolet Lumina APV timing chain replacement align with this application range.

This part cross-references 5591141100 for the same application.

Common Problems This Part Addresses

• Excessive timing chain stretch

Installation Notes and Tips

Verify engine code and timing set configuration before ordering, especially on Buick applications noted with L27 and L67 engines and single-bolt cam designs. Compare the existing chain, sprocket, and component layout to the catalog notes for your vehicle, since some applications use a 3-piece set while others require additional sprockets. Always inspect related wear points during timing service and follow factory timing marks and torque specifications during installation.
