FUEL SYSTEM 20E
To fit
1 Fit a new joint (A1) to the timing case. Fit a new
"O" ring (A3) to the fuel pump. DB4 fuel pumps are
fitted with a rubber seal which has a square shape
instead of an "O" ring. When a rubber seal is fitted
it is not necessary to fit a joint.
2 Rotate the drive shaft of the fuel pump to align
the pin (A2) or key with the keyway in the drive
gear. Ensure that the pin or key is correctly fitted
and fit the fuel pump to the gear. Fit the spring
washer and the nut to retain the drive gear and
tighten the nut lightly.
3 Align the mark on the flange of the fuel pump
with the mark on the rear face of the timing case
(B1). Fit the flange nuts of the fuel pump. Tighten
them to 22 Nm (16 lbf ft) 2,2 kgf m.
4 Fully tighten the nut for the drive gear to 80 Nm
(59 lbf ft) 8,2 kgf m. Fit a new joint for the gear
cover and fit the gear cover.
5 Fit the fuel pipes. Connect the electrical stop
control and the control rod of the fuel pump.
6Eliminate air from the fuel system, operation
20E-08.
7 Operate the engine and check for leakage. With
the engine at the normal temperature of operation,
check that the idle speed is correct, operation
20E-07.
8 If a new fuel pump has been fitted, check the
maximum no load speed, operation 20E-07.
