Introduction
This Special Instruction provides the removal procedure and the installation procedure for the HEUI Injector.
The correct procedures and tooling specifications must always be used. Failure to follow any of the procedures may result in damage, malfunction, or possible engine failure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
The injector is not serviceable. The warranty and/or the core credit for remanufacturing may be reduced for the following reasons:
Disassembling or tampering with the injector
Not returning the injector in the original protective packaging
Damaging the injector during removal or installationNote: An injector with possible damage to the tip must be returned in the original package. The damaged injector must be clearly identified as having possible tip damage.
The injector tip was made very hard to provide a long life. This hardness also makes the tip brittle. Side loading during the installation or striking the tip against a hard object or dropping the injector can cause the tip to break or crack. Installing an injector with a cracked tip may result in major engine damage.
