This Special Instruction details instructions to change the present unit injector hydraulic pump for a HEP pump that adds an opposing tapered roller bearing The additional bearing counters gear torsional loads that can lift the rollers off the race and lead to high contact stresses. The new pump design is longer than the current pump. Certain applications will require replacing additional components due to the longer HEP pump. A new high-pressure oil line and adapter are required to connect the pump to the cylinder head.Safety Information
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, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected.
