(1) Delivery valve holder (2) Spring (3) Delivery valve (4) Fuel injection pump (5) Drain tube
Remove delivery valve holder (1) for the No. 1 cylinder.Note: Some fuel injection pumps may need to be removed to an upright position in order to remove the fuel delivery valve. Refer to Disassembly and Assembly, "Fuel Injection Pump - Remove".Note: All components of the fuel delivery valve must be kept clean. Keep the components in clean diesel fuel.
Remove delivery valve (3) from the holder.
Reinstall delivery valve holder (1) and spring (2). Tighten the fuel delivery valve to 42 N m (31 lb ft).Note: Fit the fuel injection pump to the engine if the fuel injection pump was removed.
Install drain tube (5) to delivery valve holder (1) for the No. 1 cylinder.

(6) Fuel reservoir (7) Control valve (8) Hose (9) Drain pan (10) Timing mark
Install fuel reservoir (6) with a control valve (7). Install a hose (8) from fuel reservoir (6) to the inlet of fuel injection pump (4). Fill the fuel reservoir with 0.2 L (0.21 qt) of clean fuel.Note: The fuel reservoir should be approximately 152 mm (6 inch) above the fuel injection pump.
Put drain pan (9) below drain tube (5) in order to catch the fuel.
Open control valve (7) for fuel reservoir (6). If the fuel injection pump is set correctly, then the fuel should flow through drain tube (5) .
From the front of the engine, turn the crankshaft in a clockwise direction until the flow of the fuel is reduced to 1 drop for every 7 to 10 seconds. This should be the correct timing mark (10) .

(4) Fuel injection pump (11) Shim
Ensure that timing mark (10) is correct with Table 1.
Table 1
Engine description     Maximum Rated Engine Speed (RPM)     Injection Timing (BTC)    
C1.5     1500     14° 1°    
C1.5     1800     14° 1°    
C2.2     1500     12° 1°    
C2.2     1800     12° 1°    
If shim (11) must be replaced, remove the fuel injection pump and the shim.The timing will change one degree for each 0.10 mm (0.004 inch) in thickness of the shim. Thicker shims will retard the timing while thinner shims will advance the timing.Install fuel injection pump (4) and a new shim (11) of the correct thickness. Tighten all nuts and bolts to the correct torque. Refer to Specifications for additional information.Note: If a shim is not required, use a thin coat of 4C-9612 Silicone Sealant on the mating surfaces of the fuel injection pump and the cylinder block.
When the timing is correct, remove drain tube (5), fuel reservoir (6), and hose (8) .
Remove delivery valve holder (1). Assemble all of the components of the fuel delivery valve. Install the fuel delivery valve to fuel injection pump (4). Tighten the fuel delivery valve to 42 N m (31 lb ft).
Install all fuel lines in the correct position. Tighten all nuts and bolts to the correct torque. Refer to Specifications for
