air cleaner, Fig. 18. This type cleaner thoroughly
.removes all dust from the air before it enters the
carburetor. For efficient operation, the cleaner must
be serviced at regular intervals. Service the unit ac-
cording to conditions of vehicle operation.
Care of the air cleaner is extremely vital to the
life of the engine. Pay particular attention to the
amount of dust and dirt in the air taken into the
engine through the air cleaner. When dirt is not
noticeable in the air, service the air cleaner each
2000 miles [3.200 km.}. \Vhenever the air is notice-
ably dusty (for example when the vehicle is driven
on secondary roads. or through fields) then service
the air cleaner more frequently. Under extreme
continually dusty and dirty conditions where the
vehicle operates in clouds of dust and dirt, service
the air cleaner daily.
To service the air cleaner, unscrew the eye bolt on
the oil cuo clamp and remove the oil cup. Scrape
an dirt fr~m inside the oil cup and clean the inside
surface with cleaning solution. Refill with new oil
of the same viscosity as is recommended for the
engine crankcase to the oil level. bead and install
the cup securely to the cleaner body with the
attaching clamp.
Also, the air cleaner body (less oil cup) should be
removed from the vehicle and cleaned at weekly
intervals or oftener.
To do this, loosen hose clamp, and remove hose
from the cleaner.
Detach breather hose from the fitting on the
cleaner. Remove the two wing screws and lift

cleaner from vehicle. Agitate the cleaner body
thoroughly in cleaning solution to clean the filtering
element. Dry element with air hose but do not
re-oil.
Install the cleaner body in the vehicle with the two
wing screws and attach hoses securely.
Carefully check the hose clamps and fittings on the
breather hoses at frequent intervals. Loose con-
nections will affect proper operation of the crank-
case ventilating system.
8~24. Wire Gauze Air Cleaner
'9 Model DJ-3A
The air cleaner furnished as standard equipment on
Model DJ-3A is the wire gauze type shown in Fig.
19. Dust particles in the air entering the air cleaner
are deposited on the oil wetted wire gauze. This
accumulated dust on the wire gauze mesh can
choke off the air supply to the carburetor if the
dement is not cleaned at regular intervals. It is
i:nportant, therefore, that the air cleaner be
serviced every 2000 miles [3.200 km.].
To iJervice the unit, first remove -the wing nut and
cover from the air cleaner. Then lift out the wire
gauze element and wash out the accumulated dust
by plunging the element up and down in a container
filled with dean solvent. Allow the element to
&.ir dry; use of compressed air for drying the element
is not recommended. Inspect the element and the
felt seal in the cover. After the element is c!,ry, dip
it in engine oil of the same grade used for the oil
change. Allow the excess oil to drain. "\Nipe the
inside of the housing and cover clean. In&ta11 the
element and cover. 'J.'ighten the wing nut securely.

·• Models CJ-2A, CJ-3A, DJ-3A
These models are equipped with a 4-cylinder
L-head engine which incorporates an ~:;xhaust
manifold heat control valve. Lubricate the valve
sh~Jt and bushings at each 1000-mile lubrication.
Place a few drops of penetrating oil at eac:1 end of
the shaft where it passes through the r.1anifold.
Then move the valve up and down a few times to
work the oil into the bushing.
