INSTALLATION KIT 17-0105 (See line drawing on page 7.)
1. Remove existing air cleaner assembly and related hardware
including cylinder head breather fittings if applicable. Refer to
authorized Harley-Davidson® Service Manual as needed.
NOTE: Hose barb on rear cylinder head breather fitting must be removed.
To remove fitting from cylinder head, a cut-off wheel or similar tool is used
to cut barb off. Care must be taken that no metal chips get into the breather
fitting. S&S® recommends packing fitting with grease. An alternative is to
grasp barb with pliers and snap off.
2. Place head vent shim 50-7120 over breather cap screw 17-0338
and roll 5⁄8" O.D. O-ring 50-8032 into large diameter O-ring groove
closest to head of breather screw. (See Picture 4 Item A).
3. Roll 1⁄2" O.D. O-ring 50-8006 into small diameter O-ring groove of
breather screws. Apply thin film of light grease to O-rings.
NOTE: Breather fitting O-rings are easily damaged. It is suggested that
replacements be obtained prior to removing breather fittings in
future.
4. Repeat for other breather screw.
5. Pass breather screws through breather fittings 17-0337 and stock
support bracket. Do not tighten at this time.
NOTE: At least one .125" shim must be installed between breather fitting
and cylinder head. Otherwise breather screw may bottom out in cylinder
head, resulting in oil leak and possible damage to head or screw. (See
Picture 4 Item B)
6. Position the included gasket between the backplate and carb. Install
backplate on carb.
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.
7. Remove backplate and breather screw assemblies, then install shims
and reinstall breather screw assemblies. Do not tighten at this time.
8. Align breather fitting outlets to permit installation of T-hose.
9. Install rubber T-hose 17-0339 over cylinder head breather fittings
with hose tee toward rear of engine. Hose must not be kinked or
otherwise obstructed, and should be trimmed to length as needed
to align tee with backplate cut out. Once proper fit is obtained,
secure T-hose to breather fittings with black tie-wraps or clamps
provided. (See Picture 4 Item C)
10. Place wire tie or metal clamp over tee of T-hose, insert 1⁄2" steel
tube 50-8121 part way into tee and tighten clamp. Then slide short
length of beveled hose 17-0365 over 1⁄2" steel tube with beveled
end out and facing down, and tighten clamp. (See Picture 1)
11. Apply a few drops of Loctite 242 (blue) or equivalent to threads,
install nuts and lockwashers.
12. Tighten all mounting hardware.
13. Install filter element and air cleaner cover. Secure with three air
cleaner cover screws 50-0072 to complete installation.
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.
14. 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 correct carburetor jetting.
