Caution: The fuel pump gear must be fitted to the engine before the crankshaft is rotated.
7 Carefully turn the gear counter-clockwise, by hand (C1), to remove the backlash between the idler gear and
the fuel pump gear. Do not rotate the crankshaft or the fuel pump shaft. Tighten the setscrews for the fuel pump
gear to 27 Nm (20 lbf ft) 2,8 kgf m.
8 Remove the timing pin.
9 Fit the gear cover to the cover of the timing case.
Caution: Do not tighten the union nuts of the high-pressure pipes more than the recommended torque tension.
If there is a leakage from the union nut, ensure that the pipe is correctly aligned with the atomiser inlet. Do not
tighten the atomiser union nut more, as this can cause a restriction at the end of the pipe. This can affect the
fuel delivery.
10 Fit all of the pipes. Connect the control rod of the fuel injection pump. Fit the cables and connection for the
cold start advance unit and electrical stop solenoid to the pump. Ensure that a spanner is used to prevent
movement of the pump outlets when the high-pressure pipes are fitted and tighten the union nuts to 27 Nm
(20 lbf ft) 2,8 kgf m.
11 Eliminate air from the fuel system, see Operation 11-22.
12 Fit the cylinder head rocker cover.
13 Operate the engine and check for leakage with the engine at the normal temperature of operation.
