When re-fitting the new type of linkage to the fuel
pumps it is important to ensure that the radiused
shackles follow the pump radius.

6.Re-connect the speeder spring to the spigot.
If the spigot was turned when the pumps were
removed it must be turned until the hole axis is
at 90° to the camshaft before refitting the spring
when the speeder spring spigot is upright.

7.Check the governor setting; refer to "02.31
Setting the Governor".
8.Fit new joints to the fuel pump inspection doors
and replace the doors.
9.Replace the fuel pipes.
10.Prime the fuel system if it is not self-priming.
11.Check and adjust the pump timing.
2.28 FUEL PUMP TIMING
Fuel pump components are manufactured to
exacting limits and care must be taken to ensure
they are returned to their respective pumps if more
than one pump is dismantled at a time.
The fuel pump timing gauge, 317-50518, can
be used to check the timing without the need to
dismantle the pump.
Spill Timing
1.Isolate the fuel supply.
2.Remove the fuel pipe from the pump to the
injector.
3.Unscrew the fuel pump delivery union body (A)
and remove it.
4.Lift out the delivery valve spring seat (B) and
spring (C).
Figure 02.28.1 Fuel Pump Components
5.Carefully lift out the delivery valve (D) taking care
not to disturb the valve seat.
6.Place these components in a suitable container
of clean fuel.
7.Replace the delivery union body (A).

by removing a cylinder fuel pump housing door
and manually moving the fuel pump rack towards
the gear end.
10.Turn the flywheel, in the direction of rotation,
until the piston for the cylinder being timed is at
'FP' on the compression stroke.
At this position both the inlet and exhaust valves
will be closed.
11.Connect the fuel supply and bleed the fuel filter
and pump.
12.Carefully turn the flywheel against rotation until
fuel is flowing from the spill pipe.
13.Turn the flywheel very slowly in the direction of
rotation until the fuel flow from the spill pipe just
stops dripping this is known as the 'Spill Point'.
14.Check the flywheel timing mark.
The flywheel timing mark (FP), which can be
seen through an aperture in the fanshroud,
should align with the arrow on the fanshroud.
15.If the flywheel mark is not correct, see 'Figure
2.28.2', the shims under the fuel pump must be
adjusted, see "Timing Shims".
