Wires on Starter Side of Engine
Wires on Oil Filter Side of Engine
NOTE: Do not completely tighten screws until all items
are installed to allow shifting for hole alignment.
1. Pull wire harness and spark plug leads out through
appropriate openings in shrouding.
2. Slide blower housing into position over front edge of
inner bafes. Start a few of screws to hold it in place.
3. Position outer bafes and secure using screws (two

head), including any lifting strap or attached
bracket(s). Install two short screws in upper
mounting holes of outer bafes (into backing plates).
Use short screw on left side to mount wire harness
bracket. Be sure any leads are routed out through
proper offsets or notches, so they will not be pinched
between blower housing and bafes.
4. Tighten all shrouding fasteners. Torque blower
housing screws to 6.2 N·m (55 in. lb.) in a new hole,
or to 4.0 N·m (35 in. lb.) in a used hole. Torque
shorter M5 side bafe screws to 4.0 N·m (35 in. lb.).
Torque M5 side bafe screws (into cylinder head) to
6.2 N·m (55 in. lb.) in a new hole, or to 4.0 N·m
(35 in. lb.) in a used hole. Torque two lower M6
bafe mounting screws to 10.7 N·m (95 in. lb.) in a
new hole, or to 7.3 N·m (65 in. lb.) in a used hole.
5. If engine had a plastic debris screen that overlaps
blower housing, reinstall it now. Torque mounting
screws to 4.0 N·m (36 in. lb.). For a metal screen,
apply Loctite
