5. Using a light, visually check that sufficient
clearance exists between the cooling system
components and bottom of flywheel. See
Figure 11-71.
• If clearance is OK, continue with installation
of ignition modules.
• If clearance is insufficient or contact is noted,
remove the flywheel and adjust as required.
Reinstall the flywheel and recheck for
adequate clearance.

Install Ignition Modules
1. Rotate the flywheel magnet away from the
ignition module mounting bosses.
2. Install the two ignition modules, with the
ground terminal "out", onto the crankcase
mounting bosses, using the four hex flange
screws. Slide the ignition modules away from the
flywheel as far as possible, and tighten the four
screws.
3. Rotate the flywheel to position the magnet
directly under one of the ignition modules.
4. Insert a 0.25 mm (0.010 in.) flat feeler gauge or
shim stock between the magnet and ignition
module. Loosen the hex flange screws enough to
allow the magnet to pull the module against the
feeler gauge.
5. Torque the two hex flange screws to 4.0 N·m
(35 in. lb.). See Figure 11-72.
Figure 11-72. Torquing/Setting Ignition Module
Gap.
6. Repeat steps 3 to 5 for the other ignition module.
7. Rotate the flywheel back and forth checking
for clearance between the magnet and ignition
modules. Make sure the magnet does not strike
the modules. Recheck the gap with a feeler
gauge and readjust if necessary. Final air gap:
0.203/0.305 mm (0.008/0.012 in.).
8. Connect the kill leads to the ignition modules.
Route the wiring harness and kill leads as shown
in Figures 11-73 and 11-74. Push (bend) the loop
portion of the clamp on the #1 side back, as far as
possible, for maximum clearance from fan.
