SERVICE MANUAL UPDATE

NOTICE: THIS BULLETIN SUPERSEDES CURRENT AND PAST SERVICE MANUAL PROCEDURES.

A set of revised service procedures has been developed for replacement of camshaft timing gears. The revised methods do not require the complete removal of the engine from the vehicle. Cam gear replacement is generally accomplished by partially lowering the engine/cradle assembly to gain access to the cam gear.

This bulletin contains two separate and complete procedures for servicing cam gears on A, and N cars.
