Introduction

This Special Instruction provides the rework procedure for the replacement of the fuel transfer pump that is located on the HEUI pump. The procedure calls for a temporary bolt that is used during the removal of the fuel transfer pump in order to prevent the body of HEUI pump from separating. Once the fuel transfer pump has been reinstalled onto the HEUI pump, the temporary bolt is then removed.

 

 


NOTICE
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.

 

 


NOTICE
Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.


 

 


NOTICE
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 Dealer Service Tool Catalog” for tools and supplies suitable to collect and contain fluids on Caterpillar products.

Dispose of all fluids according to local regulations and mandates.

Removal of the HEUI Pump

Prior to removing the HEUI pump, wash the engine in order to remove all of the dirt from the area that surrounds the HEUI pump. Remove the HEUI pump. Refer to Disassembly and Assembly, “Unit Injector Hydraulic Pump – Remove” for the correct procedure.

Note: Do not allow any debris to enter the HEUI pump or the HEUI pump parts. Allowing debris to enter the HEUI pump will cause pump failure.

Note: Do not attempt to perform this rework procedure while the HEUI pump is still on the engine.
