Checking the pulser coil air gap
1. Turn the flywheel clockwise to align the
projection of the flywheel with the pulser
coil projection.
2. Measure the gap between both projec-
tions with a thickness gauge. Adjust if out
of specification.
3. Remove the flywheel magnet nut and fly-
wheel magnet.
4. Loosen the pulser coil screws, adjust the
pulser coil
1
position, and then tighten
the screws finger tight.
5. Set the flywheel magnet and then check
the gap again and, if necessary, repeat
steps 3–5.
6. Tighten the pulser coil screws and fly-
wheel magnet nut to the specified
torques.
