Installation Procedure


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, "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.

    Typical example

  1. Clean the mating surfaces of the fuel transfer pump on the cylinder block and clean the flange (2) of the fuel transfer pump.

    Note: Ensure that the camshaft lobe for the fuel transfer pump is at minimum lobe lift before the fuel transfer pump is installed. The fuel transfer pump can be oriented in two positions. Ensure that the fuel transfer pump is oriented in the correct position.

  2. Install a new O-ring (3) to the fuel transfer pump (1).

  3. Lubricate the operating plunger of the fuel transfer pump (1) with clean engine oil.

  4. Install the fuel transfer pump (1) to the engine. Ensure that the operating plunger is positioned correctly on the camshaft lobe.

  5. Install the two setscrews (4) that fasten the fuel transfer pump (1) to the cylinder block. Tighten the setscrews to a torque of 6 N·m (4.5 lb ft).

  6. Loosely install the hose clamps to the fuel lines. Connect the appropriate fuel lines to the fuel inlet and the fuel outlet of the fuel transfer pump (1). Tighten the hose clamps.

    Note: The fuel inlet for the fuel transfer pump can be rotated 360 degrees by loosening setscrew (5). The fuel inlet is adjustable in 15 degree increments. If adjustment is made to the position of the fuel inlet, tighten setscrew (5) to a torque of 2.5 N·m (22 lb in).

  7. Prime the fuel system. Refer to Testing and Adjusting, "Fuel System - Prime" for additional information.
