2.27 THE FUEL PUMP
The individual fuel pumps are located at the side of
the engine between the push rods and are secured
to the crankcase by two bolts. Early TS engines
were fitted with a long headed bolt fitted to the
inside hole in the pump mounting flange.
Removing the Fuel Pumps
1.Drain the fuel tank or isolate the fuel supply.
2.Disconnect the fuel feed pipes at the pumps.
3.Remove the fuel pipes from the pumps to injectors
taking care to hold the fuel pump delivery valve
holder with a spanner to prevent it turning.
4.Remove the fuel pump inspection doors.
5.Release the spring tension of the speeder spring
by unscrewing the speed adjusting screws on the
side of the crankcase.
6.Using long nose pliers disconnect the speeder
spring from its spigot.
It may be necessary to turn the spigot until
the hole axis is parallel to the camshaft before
removing the spring.
7.Disconnect the governor and pump interconnecting
linkage at the pumps.

A - Early TS/TR
B - Later TS/TR and all TX
8.Move the rack operating lever on the pump to the
central position.
9.Remove the fuel pump holding down bolts.
10.Gently lift out the pump taking care to retain the
timing shims which are between the pump flange
and crankcase.
CAUTION
If more than one pump is being removed care
must be taken to retain the timing shims with
their respective pump.
Fuel Pump Maintenance
It is recommended that the work of servicing the
fuel pump is carried out by accredited Service
Depots For operators wishing to carry out their
own maintenance, reference should be made to
the relevant Master Parts Manual.
Timing Shims
To improve the accuracy of fuel pump timing the
'sickle' type shims (A) have been replaced by full
form 'ring' types (B). The two types of shim should
not be mixed on the same pump.
The 'ring' type can only be fitted with the pump
removed from the engine.
Figure 2.27.2 Timing Shims
The 'ring' type are available in 0.127, 0.762, 1.016
and 1.276mm sizes and were first fitted on:
40 00213 TS1
40 00113 TR1
40 00297 TS2
40 00135 TR2
40 00223 TS2
40 00039 TR3
In all instances it is recommended that the
thickest shim is fitted next to the crankcase and it
is advisable to fit the minimum number of thinner
shims as possible
Refitting the Fuel Pumps
1.If 'ring' type shims are being fitted place them
onto the fuel pump taking care not to damage the
pump sealing ring.
2.Place the pumps into the crankcase and fit the
retaining bolts finger tight only.
3.If 'sickle' type shims are being fitted place the
pumps into the crankcase and fit the retaining
bolts finger tight only: the pumps should be
slightly above the face of the crankcase.
Replace the shims between the pump and
crankcase taking care to ensure that the same
thickness of shims are on each side of the
pump.
4.Evenly tighten the retaining bolts to a torque of
9.0Nm (6.6lbf ft).
5.Connect the governor link and the fuel pump
interconnecting linkage as shown.

8. Move the rack operating lever on the pump to the central
position.
9. Remove the fuel pump holding down bolts.
10. Gently lift out the pump taking care to retain the timing
shims which are between the pump flange and crankcase.
CAUTION
If more than one pump is being removed care must be
taken to retain the timing shims with their respective
pump.
