MAINTENANCE OPERATIONS
CLEANING FILTERING ELEMENT
The cellulose fibre filter ele-
ment must never be cleaned
with a solvent or cleaning solu-
tion. Also, oil must not be added
to the surfaces of the filter ele-
ment or air cleaner body.
There are two procedures that can
be used to clean the air filter element.
One method is performed with the
use of compressed air. The other is
performed by tapping the element on
a smooth horizontal
surface.
Compressed Air Method. Direct
a stream of compressed air through
the element in the directioh opposite
that of the intake air flow, that is
from the inside outward. Extreme
care must be exercised to pre-
vent rupture of the element
material.
Tapping Method. Hold the ele-
ment in a vertical position and tap
it lightly against a smooth, horizontal
surface to shake the dust and dirt
out.
Do not deform the element or
damage the gasket surfaces by
tapping too hard. Rotate the filter
after each tap until the entire outer
surface has been cleaned.
Inspection. Hold the filter in
front of a back-up light and carefully
inspect it for any splits or cracks. If
the filter is split or cracked, replace it.
CLEANING BODY AND COVER
Clean the air cleaner body and the
cover with a solvent or compressed
air. If the air cleaner contains an
opening for the crankcase ventilation
system air flow, probe the opening to
assure removal of deposits. Wipe the
air cleaner dry if a solvent is used.
Inspect the air cleaner body and
cover for distortion or damage at the
gasket mating surfaces. Replace the
cover or body if they are damaged
beyond repair.
INSTALLATION
1. Install a new air cleaner mount-
ing gasket on the carburettor, if
necessary.
2. Install the air cleaner body on
the carburettor or position the air
cleaner and air intake duct and valve
assembly on the carburettor.
3. Place the air cleaner filter ele-
ment in the air cleaner body.
Make sure the filter is properly
seated. If the word TOP is indi-
cated on the filter element, make
sUN the word TOP faces up.
4. Install the cover and tighten the
wing bolt.
CHECK BRAKE MASTER CYLINDER
FLUID LEVEL
1. Remove the filler cap from the
master cylinder. The diaphragm
which seals the master cylinder
should come off with the cap.
2. Fill the reservoir to
i
inch from
the top with approved fluid.
3. Install the filler cap, making
sure that the diaphragm is properly
seated in the cap.
CHECK CLUTCH MASTER
CYLINDER FLUID LEVEL
1. Remove the filler cap from the
master cylinder.
2. Top up the reservoir to
t
inch
below the top face, with approved
fluid.
3. Install the filler cap.
CHECK POWER STEERING
RESERVOIR FLUID LEVEL
Start the engine, turn the steering
wheel all the way to the left and right
several times, and shut off the engine.
Check the fluid level in the reser-
voir. If the level is low, add enough
fluid to raise the level to the bottom
of the filler neck. Do not overfill
the reservoir.
CHECK BATTERY FLUID LEVEL
The battery is mounted under the
hood at the right front side of the
engine
compartment.
Keep the fluid in each battery cell
up to the level of the ring in the
bottom of the filler well. Generally,
tap water may be added unless it
has a high mineral content or has
been stored in a metal container.
CLEAN CHOKE EXTERNAL
LINKAGE
Examine the choke external linkage
for free operation. If the linkage ap-
pears to be sticking, or is dirty, clean
the linkage using a brush and com-
mon mineral-spirits type cleaning
fluid. Operate the choke plate manu-
ally to make sure that it moves freely.
Lubricate the choke plate shaft at
each end and the choke operating link
with engine oil if necessary. Refer to
the applicable section for choke
adjustment specifications.
IDLE SPEED AND FUEL MIXTURE
All XA/ZF Falcon/Fairlane
carburettors are equipped with idle
fuel mixture adjusting limiters. The
limiters control the maximum idle
richness and help prevent
unauthor-
ized persons from making overly rich
idle adjustments.
The plastic idle limiter cap is in-
stalled on the head of the idle fuel
mixture adjusting screw(s) (Figs.
13
and 14). Any adjustment made on car-
burettors having this type of limiter
must be within the range- of the idle
adjusting limiter. Under no cir-
cumstances are the idle adjusting
limiters or the limiter stops on
the carburettor to be mutilated
or deformed to render the limi-
ters inoperative. On the Motorcraft
21 00-D 2-V
carburettor,
the power
valve cover must be installed with the
limiter
stops on
the
cover in
