New 1000 Series
To remove
Caution: A new fuel injection pump may be supplied
with the pump shaft in the locked position. The drive
shaft of the pump must not be turned without the
spacer (A2) in position under the locking screw (A1).
Before the crankshaft is turned or the pump is fitted,
put the spacer into position under the locking screw to
ensure that the pump drive shaft is released.
1 Disconnect the battery before the fuel injection
pump is removed from the engine.
2 Set the engine to TDC on the number 1 cylinder on
the compression stroke,
see operation 17-1 or , see
operation 17-2 .
3 Remove the gear cover from the cover of the timing
case. For gear driven coolant pumps: Remove the
coolant pump,
see operation 21-2 .
4 Insert the timing pin (B5) through the hole (B3) in
the fuel pump gear and the slot of the hub (B2). Push
the pin fully into the hole (B1) in the body of the fuel
pump. If the pin can be fully inserted then the pump
timing is correct. There should be no resistance when
the pin is inserted.
Caution: Use a second spanner to prevent
movement of the high-pressure outlet when the union
nut for each high-pressure pipe is released.
5 Remove the pipes. Remove the cables and the
connections for the cold start device and the electrical
stop solenoid from the fuel pump.
Cautions:
! Do not rotate the crankshaft when the pump is not
on the engine; the loose fuel pump gear may
damage the timing case. If it is necessary to rotate
the crankshaft, fit the fuel pump temporarily to
ensure that the gear is in the correct position. If the
fuel pump is fitted temporarily in order to rotate the
crankshaft, the locking screw (A1) must be
released and a spacer (A2) fitted.
! Do not release the nut (B6) from 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 moved, the
hub will need to be accurately fitted to the pump by
use of special equipment available to Perkins
distributors.
6 Remove the four fasteners (B4) and release the
fuel pump gear from the hub of the fuel injection
pump.
7 Remove the nuts from the flange of the fuel pump
and remove the pump. If access to the nuts is
restricted by, for example, a compressor, use tool
PD.239 to release the nuts.
