Special requirements
Description
Spanner for flange nut of the Bosch
fuel injection pump
Cautions:
l 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.
l 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 Inspect the "O" ring (A3) in the pump flange and, if necessary, fit a new "O" ring.
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 into position on the three studs and fit the flange nuts.
4 If the pump has a support bracket, fit the setscrew and nut of the support bracket. Ensure that force is not
applied to the fuel pump when the support bracket is fitted.
5 Tighten the flange nuts of the fuel pump to 22 Nm (16 lbf ft) 2,2 kgf m. If access to the nuts is restricted by,
for example, a compressor, use tool 21825964 to tighten the nuts.
Caution: 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 Put the fuel pump gear onto the hub of the fuel pump. The fasteners (B4) 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.
7 Insert the timing pin (B5) through the hole (B3) of the fuel pump gear and the slot of the hub (B1) until it can
be pushed fully into the hole (B2) 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 8-1 or Operation
8-2.
