Install Stator and Wiring Harness
Install Stator
1. Position stator onto mounting bosses so leads lay in
channel and recess of closure plate. They will
become captured when blower housing is installed.
If a clamp was used to retain leads, remove screw in
No. 13 location and install clamp. Hold clamp in
position and torque screw to 24.5 N·m (216 in. lb.)
2. Install two screws to secure stator and torque to
6.0 N·m (55 in. lb.), into new holes, or 4.0 N·m
(35 in. lb.), into used holes.
Install Wiring Harness
Check locking tang on terminal of violet B+ wiring
harness lead is angled upward. Insert terminal into
center location of rectifi er-regulator plug connector until
it locks into place. If not already inserted, two AC leads
from stator go in outer locations.
Install Pipe Plug or Fitting and Pulse Line for Fuel
Pump
1. Apply pipe sealant with Tefl on
®
(Loctite
®
PST
®
592™
Thread Sealant or equivalent), to 1/8” pipe plug or
90° fi tting (as equipped). Install and tighten into
tapped vacuum port of closure plate. Torque plug to
4.5-5.0 N·m (40-45 in. lb.). Turn outlet of a fi tting to
8 o’clock position.
2. If a fi tting is used, connect fuel pump pulse line and
secure with clamp. If fuel pump is attached to air
cleaner base, do not connect pulse line at this time.
Install Fan and Flywheel
CAUTION
Damaging Crankshaft and Flywheel can
cause personal injury.
Using improper procedures can lead to broken
fragments. Broken fragments could be thrown from
engine. Always observe and use precautions and
procedures when installing fl ywheel.
NOTE: Before installing fl ywheel make sure crankshaft
taper and fl ywheel hub are clean, dry and
completely free of lubricants. Presence of
lubricants can cause fl ywheel to be over
stressed and damaged when mounting screw is
torqued to specifi cation.
NOTE: Make sure fl ywheel key is installed properly in
keyway. Flywheel can become cracked or
damaged if key is not properly installed.
NOTE: Always use a fl ywheel strap wrench or fl ywheel
holding tool to hold fl ywheel when tightening
fl ywheel fastener. Do not use any type of bar or
wedge between cooling fi ns or fl ywheel ring
gear, as these parts could become cracked or
damaged.
1. Install appropriate key into crankshaft keyway.
Based on crankshaft keyway style, use either a
woodruff or straight key. Make sure key is fully
seated.
2. Install fl ywheel onto crankshaft aligning keyway with
key. Be careful not to shift or unseat key.
3. Position fan onto fl ywheel, so locating pins drop into
corresponding recesses.
4. Install fan mounting plate onto fan, aligning four
cutouts, followed by heavy fl at washer and screw.
5. Use a fl ywheel strap wrench or holding tool to hold
fl ywheel and torque screw. For an M10 screw, torque
to 66.5 N·m (49 ft. lb.). For an M12 screw, torque to
88.0 N·m (65 ft. lb.).
