SECTION 3- AIR INTAKE SYSTEM
AIR CLEANER ASSEMBLY
Three types of air cleaner assemblies are used on
KT models: tear drop, square, and round.
Some air cleaners may be equipped with a specially
designed "anti-icing" system. The anti-icing sys-
tem uses heat from the exhaust manifold to pre-
vent ice buildup in the carburetor and intake
manifold during cold weather operation.
The following guidelines apply to all air cleaner
assemblies:
1. Air cleaner base must be flat on gasket of air
intake elbow. Replace base if bent or cracked.
2. Gasket surfaces of element must be flat against
base and cover to seal effectively.
3. Cover seal must be in place to reduce noise and
vibration of cover. Excess vibration can cause
stud hole in cover to enlarge, permitting dirt to
enter carburetor.
4. Wing nut must be finger tightened 1/2 to 1 full
turn after nut contacts cover-do not over-
tighten.
Refer to the instructions for the specific type of air
cleaner being serviced.
Tear Drop (Figure 3-1)
Disassembly
1. Remove the wing nut, cover, air cleaner cover
seal, and element.
2. Remove the breather hose and air intake tube
from air cleaner base.
3. Remove the screws securing base to intake
elbow. Lift base from intake elbow.
Assembly
1. Install air cleaner base and new base gasket on
elbow and secure with four 10-32 x 9/16" hex
washer head screws. Secure base to manifold
with hex nut on manifold stud.
2. Pull end of breather tube through 9/16" hole in
base making sure lips on end of tube seal
securely around hole in base.
NOTE: Early KT17 models have the breather
tube attached to intake elbow.

3. Slide airintake tube through hole in base so that
the end of tube extends into the blower housing.
The angled end of tube should face to the right
(long side-left, short side-right) when inserted
into blower housing (as seen from flywheel end).
Make sure lips on end of tube seal securely
around hole in base.
4. Place element on base.
5. Attach air cleaner cover seal to cover. Place
cover on base and secure with wing nut finger
tightened 1/2 to 1 full turn after nut contacts
cover-do not overtighten. (Seal on cover must
be in place and cover tightened to prevent
vibration.)
