Problem
The fuel injector clips may fail on certain 3176 Truck Engines which had injectors replaced after January 1, 1991. A new 6I2538 Clip, made from higher strength material, can be installed to increase the reliability and service life of the injector.
Affected Products
Model & Identification Number
The following 3176 Truck Engines if not previously reworked and stamped with "3X" next to Serial No. Plate.
3176 (2YG1-Up)
Parts Needed
Quantity per injector replaced after January 1, 1991
1 - 6I2538 Clip Add injector(s) and related seal(s) if clip is broken in more than three pieces. Add 336044 O- Ring Seal if thrust pad o-ring is damaged.
Action Required
1. Only certain date code injectors installed as field replacements after January 1, 1991 require c-clip replacement.To determine if any c-clips need reworking requires inspection of the block next to the serial plate, the top surface of the injector spring retainer, and the injector date code.
2. Check for "3X" stamped on the block next to the serial number plate. If the block has been stamped, do not proceed with the rework.3. Inspect the top surface of the injector spring retainer for a red or yellow stripe. The red or yellow indicates that the injector has the latest c-clip and that particular injector requires no further action. Engines equipped with a Jake Brake may require removal of the brake to see the top of the injector clearly.4. Injectors without red or yellow stripes require inspection of the identification label on each fuel injector. The labels can be seen just above the top surface of the valve cover base on the right side of the engine. Record the part number and date code of each injector. Refer to Illustration for the location of the part number and date code on the label. 5. Any injectors without red or yellow stripes that have the following date codes require the c-clips to be reworked.LH, MH, AJ, BJ, CJ, DJ, EJ, or FJ
It may not be possible on many engines to determine the date code from an identification label. the following hints may help in these cases.
A) Only certain part numbers were produced during the specified date code range. All others should be omitted from the rework.If the part number can be read, include the following part numbers if tae date codes are LH, MH, AJ, BJ, CJ, DJ, EJ, or FJ.

9Y99109Y99207E60107E60207E61107E61200R28330R28340R29800R2981B) Early 9Y9910 and 9Y9920 Injectors did not have identification labels. The part numbers are etched into the solenoid case. Omit these injectors from this rework.C) Early 9Y9910 and 9Y9920 Injectors had six (6) sided wrench flats where the solenoid meets the forged body. If the injector has six (6) sided wrench flats, omit the injector from this rework.D) On early injectors the identification labels were prone to falling off. These were not in the specified date code range and can be omitted from this rework.Examples:
