Information:
Introduction
Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.The actuator and pump groups of these fuel injectors are sensitive to debris in the oil. The injector may malfunction due to debris in the oil, causing seizure, or high leaks in components.
Table 1
Revision Table
Revision Summary of Changes
3 Added serial numbers. Improvement Procedure
Clean oil rail after pump failure.Reference: Refer to Special Instruction, REHS3819 for the procedure to clean the oil rail after engine failure to avoid debris in the oil system.
Use clean oil and clean filters.The life of the injector depends on the oil quality. It can be increased if good cleaning practices are performed before installing the injectors.Reference: Refer to Operation and Maintenance Manual, SEBU6250 and Operation and Maintenance Manual, SEBU6251 for direction on oil sampling intervals and optimizing engine oil life.
