To fit
Caution: The engine must be set to TDC number 1
cylinder, compression stroke before the pump is
fitted. If the crankshaft needs to be rotated, the pump
must be fitted temporarily, or the loose gear could
damage the timing case.
1 Fit a new joint (A1) to the timing case. Fit a new "O"
ring (A2) 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 Lightly lubricate the "O" ring with clean engine
lubricating oil and put the pump into position on the
timing case.
3 Put the fuel pump in to position on the three studs
and fit the flange nuts.
4 Tighten the flange nuts of the fuel pump to 28 Nm
(20 lbf ft) 2,8 kgf m.
Caution: Do not remove the nut (B2) from the shaft
of the fuel injection pump. The fuel pump hub is fitted
to the shaft in the factory to ensure that the fuel pump
is in the correct position for timing. If the hub is
removed, the hub will need to be accurately fitted to
the pump by use of special equipment available to
Perkins distributors.
5 Put the fuel pump gear onto the hub of the fuel
pump. The fasteners (B6) for the fuel pump gear
should be in the centre of the slots to allow for the
removal of the backlash. Tighten the setscrews finger
tight.
Note: The fuel pump gear will only fit in one position.
The gear is fitted with the letters C and M at the front.
6 Insert the timing pin (B1) through the hole (B5) of
the fuel pump gear and the slot of the hub (B4) until it
can be pushed fully into the hole (B3) in the body of
the fuel pump. If the timing pin cannot be pushed into
the pump body, check that the engine is correctly set
at TDC on the number 1 cylinder,
see operation 17-1
or ,
see operation 17-2
