Removal
1Disconnect the battery negative lead.
2Remove the lower facia panel from the
driver’s side.
3Prise off the securing clip and disconnect
the end of the throttle cable from the top of
the pedal (see illustration).
4Remove the two securing nuts, one
accessible from the driver’s footwell, the other
from the engine compartment, and withdraw
the pedal and bracket assembly (see
illustration).
Refitting
5Refitting is a reversal of removal, but on
completion check the throttle cable
adjustment.
Removal
1Disconnect the battery negative lead.
2Working inside the vehicle, remove the
lower facia panel from the driver’s side.
3Prise off the securing clip and disconnect
the end of the throttle cable from the top of
the pedal.
4Working in the engine compartment, free
the cable sheath from the bulkhead, and pull
the cable through into the engine
compartment. It will probably be necessary to
pull the cable grommet from the bulkhead in
order to free the cable sheath.
5For improved access, remove the air
cleaner.
6Disconnect the cable end from the throttle
linkage. The cable end may be attached to the
linkage with a balljoint and spring clip, a
spring clip only, or the cable end may simplylocate in a slot in the throttle lever (see
illustration).
7Prise off the spring clip securing the cable
sheath to the cable bracket at the carburettor
inlet manifold. Depress the four lugs on the
plastic cable retainer simultaneously so that
the retainer can be slid from the bracket, or
remove the retainer securing clip, as
applicable (see illustration). Take care not to
damage the cable sheath.
Refitting
8Refitting is a reversal of removal, but before
refitting the air cleaner, adjust the cable as
follows.
Adjustment
9Have an assistant fully depress the throttle
pedal and hold it in this position. On models
with automatic transmission, where
applicable ensure that the kickdown cable
does not restrict the pedal movement. Turn
the adjusting sleeve at the carburettor inlet
manifold cable bracket until the throttle is just
fully open. Have the assistant release and
then fully depress the throttle pedal, and
check that the throttle is again fully open.
Adjust if necessary, then refit the air cleaner.
On models with automatic transmission,
where applicable check the operation of the
kickdown cable, and adjust if necessary.1A complete strip-down of a carburettor is
unlikely to cure a fault which is not
immediately obvious without introducing new
problems. If persistent carburation problems
are encountered, it is recommended that the
advice of a Ford dealer or carburettor
specialist is sought.
2If it is decided to go ahead and service a
carburettor, check the cost and availability of
spare parts before commencement. Obtain a
carburettor repair kit, which will contain the
necessary gaskets, diaphragms and other
renewable items.
3When working on carburettors, scrupulous
cleanliness must be observed and care must
be taken not to introduce any foreign matter
into components. Carburettors are delicate
instruments and care should be taken not to
disturb any components unnecessarily.
4Referring to the relevent exploded view of
the carburettor(see illustrations),remove
each component part whilst making a note of
its fitted position. Make alignment marks on
linkages etc.
5Reassemble the carburettor in the reverse
order to dismantling, using new gaskets, O-
rings etc. Be careful not to kink any
diaphragms.
