Attention:
General Manager, Fixed Operations Manager, Technician Purpose

The purpose of this bulletin is to communicate updated service procedures to the timing chain and timing chain oiling nozzle due to design changes that have been made to both components. All timing chain kits now available in service will include the oiler nozzle. This new nozzle has higher flow rate characteristics that will increase oil flow to the timing chain under low RPM operating conditions. Whenever replacing a timing chain, it is important to replace the oiler nozzle.

Prior edition Service Manuals for the above listed vehicles refer to the timing chain index links being colored "silver" and "copper." With the implementation of the newer design chain and oiler assembly, the index link colors have changed. In order to avoid confusion, the service procedure text has been modified to refer to the index links as two common colored and one unique colored link. Please use the procedure in this bulletin to replace all previously issued Service Manuals.

The eSI website will be updated immediately and future Service Stall System SI CD releases will include this and other Service Manual updates.
