air cleaner housing. If this was removed, secure
fitting to housing with hi-lo screw. Torque screw to
2.1 N·m (19 in. lb.).
3. Install air cleaner assembly and any clips onto
mounting studs. Secure with hex flange nuts. Torque
nuts in 2 stages: first to 7.3 N·m (65 in. lb.), then
finally to 8.2 N·m (73 in. lb.), using sequence shown.
4. Install 2 screws securing support bracket to air
cleaner assembly. Torque screws to 7.9 N·m
(70 in. lb.).
5. Connect breather hose to air cleaner.
Install Muffler
1. Install port liners (if equipped). Install muffler and
attaching hardware to muffler bracket. Torque
screws to 9.9 N·m (88 in. lb.).
2. Install hex flange nuts to exhaust studs. Torque nuts
to 24.4. N·m (216 in. lb.).
Install Oil Cooler (if equipped)
1. Secure adapter to oil pan with oil filter nipple. Torque
oil filter nipple to 27 N·m (20 ft. lb.).
2. Install screws and secure oil cooler to blower
housing.
Install Oil Filter and Fill Crankcase with Oil
NOTE: Make sure that both oil drain plugs are installed
and torqued to specifications to prevent oil
leakage.

(10 ft. lb.). If oil drain valve is used, make sure valve
body is closed and cap is on.
2. Place new filter in shallow pan with open end up. Fill
with new oil until oil reaches bottom of threads. Allow
2 minutes for oil to be absorbed by filter material.
3. Apply a thin film of clean oil to rubber gasket on oil
