Information:

This Revised Service Letter replaces the 05Dec2012 (Revised 31Jan2013) Service Letter. Changes have been made to the Affected Product and Action Required.
TERMINATION DATE

PROBLEM
The existing fuel injector has a 150 degree spray pattern. During the combustion stroke (process), the current end of injection timing maps can allow the 150 degree spray pattern to temporarily impinge upon the exposed wall of the cylinder liner as the piston moves downward in the bore.
Depending on engine speed and load factors, the fuel making contact with the liner can dilute the oil film or cause excessive soot. The excessive soot can build up to form carbon deposits at the piston lands and grooves, resulting in uneven top ring and groove wear, which may cause ring breakage. This situation is aggravated by contamination within the air and lubrication systems.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 7% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
This program does not apply to 793D Off-Highway Trucks equipped with high altitude engine arrangements.
If a 793D Off-Highway Truck that is listed in the Affected Product already has 423-7547 Fuel Injectors or 20R-2296 Fuel Injectors installed, do not apply this Service Letter.
Refer to the service manual if/as necessary.
Install a full set of sixteen 145 degree fuel injectors along with the software.
NOTE 1: Do not mix the 145 degree fuel injectors with the former 150 degree fuel injectors in the same engine.
NOTE 2: Do not install the software that is listed in the Parts Needed unless all sixteen fuel injectors have been replaced by the 145 degree spray pattern fuel injectors that is listed in the Parts Needed.
