TS, TR, TX engines workshop manual 30
Notes:
The speed ranges given in the table do not necessarily relate to the full load build
speeds due to flywheel limitations.
1. The minimum full load speed must not be less than 1500r/min.
2. These codes are for earlier TS/TR engines, see "02.29 Governor Modifications - TS/
TR", that are fitted with a metal thrust washer assembly and shoes on the governor
lever and weights.
Governor Combination Code
First letter or number - weight code.
Second letter - spring colour code
(W = white, B = black, U = blue, Y = yellow)
Letter 'S' - Inner speeder spring, if fitted.
End figure - number of weights.
Dismantling the Governor
1. Remove the gear end cover.
2. Remove the fuel pump inspection door/s.
3. Disconnect the fuel pump and governor linkage at the fuel
pump using long nosed pliers.
4. Slacken off the speed control screw and then disconnect the
speeder spring.
5. Remove both fulcrum pins from the pivot support blocks
using a 1.5mm rod, punch or suitable piece of stiff wire.
Take care not to lose the shims.
6. Remove the governor lever assembly complete with the
speeder spring and fuel pump linkage.
7. Remove the governor sleeve assembly
Assembling the Governor
Assemble the governor and fuel pump linkage in the reverse
order to dismantling, taking care to note the following
points:
a. The fulcrum pins are drilled at one end only and these holes
must be fitted at the outer end.
b. Ensure the governor sleeve is fitted the correct way.
c. The speed control spring is correctly hooked into its spigot.
d. The small return spring, which is only fitted to variable speed
engines, must be fitted to the fuel pump side end of the lever
assembly with the short tail wound backwards and held
captive under the pivot support block.

perfectly free to move.
Changing Governor Weights
A table of governor weight and spring combinations
is given in "Governing Ranges to BS5514". Current
engines are fitted with an improved camshaft
gearwheel design, the weights remain the same
although on current engines they are retained in
position by sintered retaining plates with cast slots
which locate over the weight pins. Both types
are shown in 'Figure 2.30.2' and they are not
interchangeable.
1.Remove the gear end cover.
2.Remove the governor lever and sleeve
assemblies.
3.Disconnect the speeder spring from its spigot
and fit a new spring if necessary.
4.Turn the engine until one of the governor weight
retaining plate bolts is accessible.
5.Remove the bolt and plate.
6.Turn the engine until the adjacent retaining plate
bolt is accessible.
7.Remove the governor weight.
8.Repeat items 4. to 7. for the remaining weights.

9.Fit the new weights and retaining plate; take care
to ensure the weight pins are correctly seated in
their respective slots.
10.Torque the retaining plate bolts to 9.0Nm (6.5lbf ft).
11.Replace the governor sleeve and governor lever
assemblies.
12.Check the governor settings.
13.Replace the fuel pump inspection door and the
end cover.
2.31 SETTING THE GOVERNOR
Before setting the governor refer to "Governing
Ranges to BS5514" and "Governor Modifications
- TS/TR".
To adjust or check the settings, it is necessary to
remove the fuel pump inspection doors and the
end cover. The engine control must be in the start
position and the end of the camshaft gently tapped
towards the flywheel to take up any end play.

7. Remove the governor weight.
8. Repeat items 4. to 7. for the remaining weights.
