THROTTLE CONTROL
LINKAGE
SETTINGS
The settings described in Section
K4
should be carried
out before the settings contained in this Section are
attempted.
Throughout the setting procedure, reference should
be made to the appropriate illustration (see
Figs.
K33,
K34,
K35
and K36).
The settings in this Section, unless otherwise stated,
are given for the throttles in the closed position and
the 'fast-idle' mechanism in the off position.
When working on a cold engine, the 'fast-idle' off
position can be maintained by securing an elastic band
between the 'fast-idle' mechanism (when it is in the off
position) and the crankcase breather plug on the choke
housing.
Four Speed Automatic
Gearbox
(Early right-hand drive cars)
Throttle control linkage settings
Ideally the following settings should be carried out
before the engine and gearbox are fitted into the car.
I.
Set the levers on
'A'
bank control shaft, so that
the
'A'
bank to control shaft rod lever is vertical and
the
'A'
bank control shaft lever is horizontal when
the manifold to carburetter lever is connected to the
carburetter control link with all slackness in the
carburetter twin-links taken up; refrigerated cars have
links with elongated holes in them. Tighten the lever
pinch bolts.
2. Set the micro-adjuster to its mid-position and
adjust the rod length to dimension
D
in the respective
illustration.
3. Fit the micro-adjuster (long rod uppermost).
4. Lock the
T.V.
lever onto the gearbox and hold
fully back in the no
T.V.
position (i.e. forward posi-
tion). Then, with the carburetters still in the closed
throttle condition, lock the pinch bolts on the bell
housing-to-T.V. rod lever and the bell housing
micro-
adjuster lever to the bell housing cross-shaft.
5.
Turn the micro-adjuster six 'clicks' anti-clockwise
looking from the top, to take up free play in the
T.V.
linkage.
6.
Ensure that the linkage moves frcely and that the
closed and full throttle positions on the carburetters
are obtainable.
Assembly of the pedal linkage to the
carburetter and
T.V.
linkage
With the engine and gearbox installed in the car,
proceed to connect the pedal and compensator linkage
to the engine as follows.
1.
Assemble the compensator linkage to the engine
as shown in Figure K33.
2. Fit control rod (3).
3.
The setting given for control rod (3) is very
important and should not be disturbed, If however,
a new control rod is to be fitted or the original setting
has inadvertently been altered, the control rod should
be
adjusted to the dimensions given. Ideally the setting
for this rod should be measured between ball centres,
but if this cannot be accomplished fairly easily then
the setting given between the nut inner faces should be
used.
4.
Fit the pedal linkage to the body, then ensure
that it operates smoothly.
5.
Check that the pedal return spring (21) holds the
pedal against the pedal stop (if fitted).
6.
Position the accelerator pedal so that it is the
correct distance below the level of the brake pedal
(see dimension
C),
then, if a pedal stop is fitted adjust
it to maintain this position. If a pedal stop is not
fitted, a block of wood should be utilized to temporarily
maintain the pedal in the position required.
7.
Build up control rod
(7)
to dimension
B
leaving
the lock-nuts slack, then
fit
the rod to the fulcrum
lever
(5).
8.
With the accelerator pedal
set
to dimension
C,
adjust the position of the jaw (20) at the end of control
rod
(7)
so that the bolt will pass easily through the
jaw and lever
(19);
whilst fitting this rod it should be
