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
A fuel injector is considered failed if the following troubleshooting Step 1 and Step 2 are completed and the problem is not resolved. Troubleshooting is not cover by this letter.
1. Ensure ECM software is current.
2. Perform the following procedures:
KENR5424 ? Troubleshooting
SENR9937 - Electronic Unit Injector ? Adjust
SENR9937 - Electronic Unit Injector - Test
3. Replace injector(s) as required.
If one or more injectors fail replace all injectors at the time of repair.
Refer to Disassembly and Assembly, RENR9217 for the removal and installation procedure of the unit injector.
8S-9191 Injector Hold Down Bolt must be replaced. Ensure that the proper torque is achieved, 55 +/- 10 Nm (41 +/- 7 lb ft).
356-5212 Rocker Arm Shaft Hold Down Bolts must be replaced. Ensure that proper torque procedure is adhered to.
1. Position rocker arm shaft assembly (4) , valve rocker arms (3) , and electronic unit injector rocker arms (1) as a unit with 124-2946 Lifting Bracket on the cylinder head.
Note: Apply clean engine oil to the underside of the bolt heads prior to installation.
2. Install bolts (2) and tighten to a torque of 55 +/- 5 Nm (41 +/- 4 lb ft). Tighten bolts (2) again to a torque of 55 +/- 5 Nm (41 +/- 4 lb ft). Turn bolts (2) for an additional 60 +/- 5 degrees. Tighten the bolts in the following sequence: 2, 3, 1, 4.
