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.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The removal procedure is similar for the two cylinder, the three cylinder and the four cylinder engines. The Illustrations show a four cylinder engine.
Remove the fuel injection lines. Refer to Disassembly and Assembly, "Fuel Injection Lines - Remove and Install" for more information. The C0.5, C0.7, C1.1 and C1.6 engines have a flexible fuel return hose.For engines with a flexible fuel return hose, disconnect the fuel hose from the inlet connection of the fuel injection pump.

Typical example
Illustration 2 g01327006
Typical example
Gradually loosen bolts (4) and nuts (2) that fasten the fuel injection pump to the cylinder block.
Carefully raise fuel injection pump (1) from the cylinder block and remove clip (7) that connects link (6) to fuel rack control (5).
Remove fuel injection pump (1) from the cylinder block.
Remove shims (3) from the mounting face of the cylinder block. Note: Record the thickness of each shim and the number of shims for reassembly. The fuel injection timing is determined by the thickness of the shim pack that is between the fuel injection pump and the mounting face on the cylinder block. Refer to Specifications, "Fuel Injection Pump" for more information.Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The installation procedure is similar for the two cylinder, the three cylinder and the four cylinder engines. The Illustrations show a four cylinder engine.
Clean the mating surfaces of the cylinder block and the fuel injection pump.
Illustration 3 g01327005
Typical example
Install the correct thickness and the correct number of shims (3) on the mounting face of the cylinder block. Refer to Specifications, "Fuel Injection Pump" for more information.
Illustration 4 g01327006
Typical example
Position fuel injection pump (1) close to the mounting face of the cylinder block, and connect link (6) and fuel rack control (5) with clip (7).
Align fuel injection pump (1) with the studs on the cylinder block. Install the fuel injection pump to the cylinder block.
Install bolts (4) and nuts (2). Ensure that the tube clip for the engine oil line is secured by the appropriate fastener. For C0.5, C0.7, C1.1 and C1.6 engines, evenly tighten bolts (4) and nuts (2) to a torque of 6 N m (53 lb in).For C1.5 and C2.2 engines, evenly tighten bolts (4) and nuts (2) to a torque of 15 N m (11 lb ft).
Install the fuel injection lines. Refer to Disassembly and Assembly, "Fuel Injection Lines - Remove and Install". The C0.5, C0.7, C1.1 and C1.6 engines have a flexible fuel return hose.For engines with a flexible fuel return hose, connect the fuel hose to the inlet connection of the fuel injection pump.End By:
Install the fuel shutoff solenoid. Refer to Disassembly and Assembly, "Fuel Shutoff Solenoid - Remove and Install".
