Introduction
Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.MEUI-C fuel injectors installed in certain C13 and C15 truck engines have failed due to issues not related to materials or workmanship of the injector. Injector solenoid failures have occurred due to fuel system restrictions and connector pin arcing. Other injector failures have been related to incorrect injector rocker preload. To prevent more failures, further troubleshooting and inspection of the fuel system and electrical connectors is necessary to determine the root cause of the solenoid failure. Likewise, if injector tappet or injector rocker failures are observed, investigations should review that correct injector preload procedures were followed.Note: Failures of injectors that are not due to defects in manufacturing or materials may not be warrantable failures.

Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs.A person must be alert to potential hazards. This person must also have the necessary training, skills, and tools to perform these functions properly.Safety precautions and warnings are provided in this instruction and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons.Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. The warnings in this publication and on the product are, therefore, not all inclusive. Do not use this product in any manner different from what is considered by this manual without first satisfying that you have considered all safety rules and precautions applicable to the operation of the product in the location of use, including site-specific rules and precautions applicable to the worksite. If a tool, procedure, work method, or operating technique that is not recommended by Caterpillar is used, you must satisfy that it is safe for you and for others. Ensure that you are authorized to perform this work, and that the product will not be damaged or become unsafe by the operation, lubrication, maintenance, or repair procedures that you intend to use. The information, specifications, and illustrations in this publication are based on information that was available at the time that the publication was written. The specifications, torques, pressures, measurements, adjustments, illustrations, and other items can change at any time. These changes can affect the service that is given to the product. Obtain the complete and most current information before you start any job. Cat dealers have the most current information available.Safety Section
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
Personal injury can result from improper handling of chemicals.Make sure you use all the necessary protective equipment required to do the job.Make sure that you read and understand all directions and hazards described on the labels and material safety data sheet of any chemical that is used.Observe all safety precautions recommended by the chemical manufacturer for handling, storage, and disposal of chemicals.
Before servicing/performing maintenance on the machine, electrical power must be physically disconnected; battery plugs must be disconnected from the batteries, or the trailing cable must be unplugged, and warning tags and padlocks shall be applied by a certified electrician. Certified electricians shall perform or direct any electrical work, including any energized testing, repair work in controllers, motors, or other approved compartments, and shall insure that all compartments are properly closed and inspected prior to re-energization. All applicable lock out and tag out procedures must be followed.
Observe the safe working load limits of all lifting and blocking devices and keep a safe distance from suspended/blocked loads. Personnel may be seriously injured or killed by falling loads.
Connector Pin Arcing
Injector solenoid diagnostic codes can be a result of poor electrical connections between the injector and injector harness. When troubleshooting a suspected injector failure, carefully inspect injector connector pins for signs of arcing. If arcing is observed, both injector and harness must be replaced due to damaged connector pins and sockets. Connector pin arcing can also be caused by improper removal the harness from the injector. When removing the harness use approved tool 458-3562 Tool As. Refer to Illustration 2.
