1. Be sure sealing surfaces of crankcase and breather
cover are clean of old gasket material. Do not
scrape surfaces as this could result in leakage. Use
a new gasket when installing breather cover.
2. Check to make sure there are no nicks or burrs on
sealing surfaces.
3. Position breather gasket and cover on crankcase.
Install screws in locations 3 and 4. Finger tighten at
this time.
4. Install inner baffles using remaining screws and
finger tighten. Do not torque screws at this time;
they will be tightened after blower housing
Install Oil Temperature Sensor (ECV EFI)
NOTE: Ensure part is clean, undamaged and free of
debris and make sure electrical connector has
seal in place.
1. Lightly lubricate oil temperature sensor O-ring and
install oil temperature sensor into breather cover.
2. Torque sensor to 7.3 N·m (65 in. lb.).
3. Push electrical connector on oil temperature sensor
making sure a good connection is made.
Install Oil Sentry (If equipped)
™
1. Apply pipe sealant with Teflon
Thread Sealant or equivalent) to threads of Oil
Sentry switch and install it into breather cover.
™
Torque to 4.5 N·m (40 in. lb.).
2. Connect wire lead (green) to Oil Sentry™ terminal.
Install Blower Housing and Outer Baffles
NOTE: Do not completely tighten screws until all items
are installed to allow shifting for hole alignment.
1. Slide blower housing into position over front edge of
inner baffles. Start a few screws to hold it in place.

2. Position outer baffles and secure using M6 screws
Install M6 screws (20 mm long) into intake port side
of cylinder heads, including any lifting strap. Install
M6 screws (16 mm long) into exhaust port side of
cylinder head. Install short M5 screws (10 mm long)
in upper mounting holes of outer baffles (into
backing plate). Be sure any leads are routed out
through proper offsets or notches, so they will not be
pinched between blower housing and baffles.
3. Insert and tighten all remaining blower housing and
baffle screws with exception of rectifier-regulator
grounding bracket screw. Torque all blower housing
and baffle M6 screws assembled into aluminum to
10.7 N·m (95 in. lb.) for a new hole, or 7.3 N·m (65
in. lb.) for a used hole. Torque all blower housing
and baffle M5 screws assembled into sheet metal
(backing plate)to 2.8 N·m (25 in. lb.) for new holes,
or 2.3 N·m (20 in. lb.) for used holes.
4. Torque breather cover screws to 11.3 N·m (100 in.
lb.) into new holes or 7.3 N·m (65 in. lb.) into used
holes in sequence shown. Note first screw is torqued
a second time.
Install Reconnect Rectifier-Regulator
NOTE: Rectifier-regulator middle terminal (B+) is offset
(not equally spaced) from outer terminals (AC).
Verify rectifier-regulator plug is assembled to
match terminal offset of rectifier-regulator.
1. Install rectifier-regulator in blower housing if
removed previously, then secure grounding bracket
against outer side of rectifier-regulator with a silver
screw.
2. Torque black rectifier-regulator screws to 1.4 N·m
(12.6 in. lb.) and silver ground strap screw to 2.8
N·m (25 in. lb.) into new holes or 2.3 N·m (20 in. lb.)
into used holes.
3. Connect plug to rectifier-regulator. If purple wire was
removed, verify locking tang is raised on terminal
and push wire terminal into plug prior to connecting
to rectifier-regulator.
