remove the mounting bolt.
b. Move the generator a small distance in either the forward or rearward direction
to make a small increase or decrease incremental change to the belt tension.
c. Retighten the adjustment bolt and measure the belt deflection. Hold a ruler
behind the belt while firmly pressing down on the belt and reading the belt
deflection distance. The belt deflection should have a nominal 1/4 in (6.5 mm)
belt deflection.
d. Repeat the tension adjustment steps until the belt tension is within spe-
cification.
CAUTION:Do not over tension the belt which will lead to premature belt wear and
possible damage to the generator pulley.
8. Fully tighten the 4 mm generator mounting bracket bolt.
9. Ride and pedal the bike at high speed for several minutes and verify there are no
issues with the belt (unusual noised etc.).
10. Slow down and stop the pedals and flywheel. Remeasure and verify that the belt
deflection remains at the nominal 1/4 in (6.5 mm) belt deflectionspecification.
11. Reinstall the front and rear drive belt covers, see "Belt Guard Cover Replacement" on
page47.
12. Verify the bike operation per "Operation Verification Checklist" on page14 and return
to service.
