APRIL 195036ENGINE TIMING
OCTANE SELECTOR.
The timing of the ignition is controlled automatically by mechanism in the
distributor. In addition, an octane selector is fitted. This is a vernier
adjustment attached to the distributor (Fig. 7) fitted with a sliding portion
controlled by an adjusting screw and a calibrated scale marked R (retard)
and A (advance) with a number of divisions between. The standard setting
for the ignition is with the long line of the scale on the sliding portion
against the mark...

APRIL 195037VALVE TIMING.
If the timing chain and hydraulic tensioner should have been removed, the
procedure to re-time the engine is as follows (See Fig. 11).
(1) Set the exhaust tappets as instructed on Page 38 and slacken the inlet
tappet adjusting screws as far as possible.
(2) Rotate the camshaft in the running direction until No. 1 exhaust valve
is fully open.
The  use of a dial indicator is the only reliable method of determining this
point. It should be mounted on a stud adjacent to No. 1...

APRIL 195038do the job correctly without a dial indicator, but much time is wasted and
the possibilities of an error very much magnified.
(3) Rotate the engine in the running direction until the E.P. mark oil the
flywheel is in line with the pointer.
(4) Fit the timing chain, ensuring that there is no slack on the driving side
(G).
(5) Hold the ratchet pawl (E) clear and replace the complete pulley (C, F
and H), meshing the pulley with the chain.
(6) Check the timing and correct if necessary. The...

lock-nut should be securely tightened after adjustment, great care being
taken to ensure that this operation does not upset the clearance.Fig. 12. Inlet tappet adjustmentFig. 13.  Exhaust tappet adjustment

The tappet clearance should be set with the engine either cold or at running
temperature and it is essential to ensure that the valve to be adjusted is...

travel, turn the nut in an anti-clockwise direction half a turn at a time and
make sure that the nut is against the pin, before checking the pedal
movement. (Fig. 14).

damage. A vacuum valve is also fitted to the filler cap to relieve the
depression resulting when the engine has cooled down after running at
extremely high temperatures.
The standard radiator cap incorporates a relief valve which opens at
approximately 5 lb. per sq. in. (0,35 Kg/cm2.). A special cap is available as
an item of extra equipment for use when the vehicle is employed under very...

to circulate only round the engine until a predetermined temperature is
reached, when it opens to allow full circulation through the radiator. The
unit operates at 167 – 190 F. (75 – 88 C.) and this setting cannot be altered
in any way.
If overheating of the engine should occur, check that the thermostat is
functioning correctly; to do this, remove the thermostat from its housing
and run the engine; if the...

APRIL 195043SERVICE ATTENTION.
It is a good plan to always inspect the cooling system at the same time as
the engine oil level is checked, i.e., daily under normal conditions. This care
would largely prevent the possibility of a sudden and costly delay due to
coolant loss and consequent engine failure. The inspection need only take a
few moments and should include the following points:-
(i) Water level in radiator – should be to the bottom of the filler neck.
(ii) Condition of all water hoses – freedom...

APRIL 195044The anti-freezing mixture should be well mixed to the required strength in a
separate container and added after thoroughly flushing out the system (do
not simply add the correct amount of glycol through the radiator filler); run
the engine for a short while to assist good circulation.
It is important when the winter is over, that steps be taken not only to drain
off the mixture, but to flush the system through several times with very hot
soda water in order to remove all traces. Failure to...

APRIL 195045The filler is readily accessible by lifting the lid in the top of the seat-box on
the right-hand side
(Fig 4). Except on a
few early vehicles, a
strap is provided on
the back-rest panel
to hold the lid in the
open position. Turn
the cap in an anti-
clockwise direction
to lift it off, which
action will reveal a
filler tube which can
be drawn out and
locked by a slight
movement to the
left, to facilitate
filling. Care should
be taken to prevent
the entry of water or
foreign matter. The capacity...
