INSTALLATION KIT 17-0199 (See line drawing on page 6.)
1966-1984 shovelhead and for 1957-1985 Harley-Davidson®
Sportster® models
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 shovelhead and 1957-1979 ironhead Sportster®
models – press plugs 50-8313 into holes “D" in backplate.
(See Figure 1)
B. 1980-1984 shovelhead and 1980-1985 ironhead
Sportster® models – apply PTFE plumber’s tape or thread
lubricant to threads of crankcase breather vent elbow
tting 50-8110 and install in hole “A" in backplate. (See
Figure 1)
3. Attach mounting bracket to engine. Do not tighten bracket
completely at this time.
A. 1966-1982 shovelhead normally utilize bracket 17-0092,
which attaches to bottom of front rocker box and air
cleaner backplate.
B. Ironhead Sportster® models normally utilize bracket
17-0093, which attaches to front intake lifter guide bolt
and air cleaner backplate.
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.
4. Align hole in other end of bracket with hole in backplate. Bracket
may require slight bend or shims for correct t. If gap exists
between backplate and mounting bracket, install shims or washers
(not supplied) to ll gap. Secure bracket to backplate with 1⁄4-
28 bolt, atwashers, and Nyloc locknut. Tighten to 10-12 ft-lbs. If
bracket attaches to manifold bolt, conrm 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.
5. Apply a few drops of Loctite® 242 (blue) or equivalent to threads,
install nuts and lockwashers, and tighten.
6. Tighten all mounting hardware.
7. Install crankcase vent hose to tting installed in step 2.
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.
8. Install lter element and air cleaner cover. Secure with three air
cleaner cover screws 50-0072 to complete installation.
9. Start motorcycle, inspect for leaks, and test ride. Engine should run
smoothly after proper warm-up. Surging or misre may indicate lean
carburetion. If necessary, consult professional mechanic regarding
possible need to install larger carburetor jetting.
