S&S Worldwide Air Cleaner - Manual (Page 2)

NOTES
● Air cleaner assembly must be firmly supported.
S&S includes support brackets only with kits for OEM
carb or single runner fuel injection. Brackets for other
applications are listed in the S&S catalog and may
be purchased separately.
● Parts from different year group installed on
motorcycle by previous owners may require different
support bracket. Adjustable bracket #16-0471
attaches to center case bolt and lower carb-manifold
bolt. It is recommended for 1983-’84 Shovels and
works on most other models as well.
● Kits may contain wire ties or metal clamps for
securing vent hoses depending on application.
● A 36” length of hose is provided for race
applications. This hose may be used to route
crankcase fumes/oil mist to a ‘catch can’ or similar
device as required and approved by race organizer.

(See line drawing on page 6.)
1. Remove existing air cleaner assembly and
related hardware, if applicable. Refer to
authorized Harley-Davidson Service Manual
as needed.
2. Prepare air cleaner backplate.
A. 1966-1979 Shovels and 1957-1979
Ironhead Sportsters - Press plugs #50-8313
into holes “D” in backplate. (See Figure A)
B. 1980-84 Shovels and 1980-1985 Ironhead
Sportsters - Apply Teflon tape or thread
lubricant to threads of crankcase breather
vent elbow fitting #50-8110 and install in
hole “A” in backplate. (See Figure A)
3. Attach mounting bracket to engine. Do not
tighten bracket completely at this time.
A. 1966-1982 Shovels normally utilize bracket
#17-0092, which attaches to bottom of front
rocker box and air cleaner backplate.
B. Ironhead Sportsters normally utilize bracket
#17-0093, which attaches to front intake
lifter guide bolt and air cleaner back plate.
NOTE - Backplate screws supplied with this kit have
thread locking compond on threads. If screw without
thread locking compound is used, a thread locking
compound such as Loctite 242 must be applied, and
screws properly tightened.
5. Align hole in other end of bracket with hole in
backplate. Bracket may require slight bend or
shims for correct fit. If gap exists between
backplate and mounting bracket, install shims
or washers (not supplied) to fill gap. Secure
bracket to backplate with
1 ⁄
4
-28 bolt, flatwashers,
and Nyloc locknut. Tighten to 10-12 ft-lbs. If
bracket attaches to manifold bolt, confirm that
adequate thread engagement exists between
bolt and carburetor body. If longer bolt is
required, insure that bolt is not long enough to
bottom out against carburetor
6. Apply a few drops of Loctite 242 (blue) or
equivalent to threads, install nuts and
lockwashers, and tighten.
7. Tighten all mounting hardware.
8. Install crankcase vent hose to fitting installed
in step 2.
WARNING - Vent hose must not contact hot or
moving surfaces that could damage it and expose
brakes or tires to crankcase oil/air mist. Oil on these
components could result in loss of control of
motorcycle with death or severe injury to operator
and others.
9. Install filter element and air cleaner cover. Secure
with three air cleaner cover screws #50-0072 to
complete installation.
10. Start motorcycle, inspect for leaks, and test ride.
Engine should run smoothly after proper warm-
up. Surging or misfire may indicate lean
carburetion. If necessary, consult professional
mechanic regarding possible need to install
larger carburetor jetting.
