Governor 'A' Setting
1. Set the distance 'A', between the end of the thrust
sleeve and the shoulder on the camshaft gear hub,
to 5.0mm (0.197in) on early TS/TR engines and
9.5mm (0.374in) on later TS/TR and all TX engines
by marking a scribed line the required distance
from the shoulder and then moving the thrust sleeve
forward to this scribed mark.
With care, an engineers screwdriver can be fitted
behind the governor sleeve to hold it in the correct
position while the next stages are carried out.
Figure 2.31.4 Governor 'A' Setting
2. Disconnect the fuel pump linkage, for the remaining
fuel pumps from No.1 pump by:
a. Sliding the oval split ring towards the gear end.
b. Lifting the spring tail from the end of the governor
link.
c. Removing the governor link from the fuel pump
rack.
3. Check that the calibration mark (X) on No.1 fuel
pump is in line with the mark on the centre of the
fuel pump body, as shown below, while the correct
distance 'A' is maintained.
Figure 2.31.5 Fuel Pump Calibration Marks
4. If the two calibration marks are not in line they can
be adjusted by altering the effective length of the
governor link through the two locknuts on the outside
of the governor lever.
Ensure the chamfered spacer is seated when
making this adjustment.
5. Replace the linkage to No.1 pump.
6. The length of the links from No.1 to No.2, and
between No.2 and No.3 pumps are then adjusted
individually by removing the relevant linkage from
the pump and rotating the link as necessary until
the calibration marks (X) on all pumps are in
line simultaneously while the distance 'A', is
maintained.
7. Release the governor lever assembly and check
that all parts of the governor move freely.
Governor 'G' Setting
The 'G' setting is used to ensure that the fuel pumps
deliver the correct amount of fuel as dictated by the
engine build number.
The various settings are given in "02.32 Governor
'G' Setting and Timing Tables". For intermediate speeds
not given in the tables use the setting for the nearest
higher speed.
All TS and TR engines built from January 1999 have
been fitted with fuel pump 201-31305 (Mk ll Pump).
These can be fitted individually as spares to replace
the earlier pumps, but improved engine idling
characteristics can only be gained by changing all
pumps in the engine to the new type. This fuel pump
supersedes earlier pumps although the fuel pump
element remains unchanged.
1. Turn the engine control to the stop position and
release it.
2. Gently move the governor assembly lever away from
the camshaft until the excess fuel device is heard
to 'click' into the run position.
3. With a feeler gauge of the correct thickness for the
build inserted between the control lever and the
lever stop, loosen the control plate retaining screw
(A) and rotate the plate (B) until the fuel pump
calibration marks are aligned.
On some engines a tamperproof setscrew is fitted.
Figure 2.31.6 Governor 'G' Setting
4. Tighten the plate retaining screw.
5. After all the settings have been carried out, ensure
the fuel pump rack and all moving parts move freely.
CAUTION
Extreme care must be taken when inserting the feeler
gauge or rotating the plate to ensure that the governor
does not move into the start position.
