DRIVE BELT DEFLECTION 1.10
INSPECTION
Check drive belt deflection:
● Inspect before every ride.
● Adjust at the 500 mile (800 km) service interval.
● Inspect at every 5000 mile (8000 km) service interval
thereafter.
NOTE
There are tight and loose spots during rear wheel rotation
that affect belt deflection. For a more precise measurement,
take three deflection readings, rotating the rear wheel
between measurements. Average the three readings for a
more precise measurement.
When checking deflection, have:
● No rider or cargo weight on motorcycle.
● Transmission in neutral.
● Belt and sprockets at room temperature.
● Motorcycle upright (not on side stand).
1. Adjust rear shock absorber spring preload.
2. Detach drive support arm and sprocket cover.
3. Unload the rear suspension by lifting the motorcycle
frame under the tail section.
NOTE
When the rear suspension is fully unloaded, the motorcycle’s
weight is not compressing the rear shock. It is not necessary
to raise the rear wheel off the ground to reach this point.
4. See Figure 1-23. Apply 10 lbs of force to belt at midpoint
of bottom strand using BELT TENSION GAUGE (Part
No. HD-35381). The deflection should be upwards as
shown.
a. Deflection (measured with 10 lbs of force) should be
1.50-1.75 in. (38.1-44.5 mm) at the bottom strand. If
deflection is within limits, see ADJUSTMENT, Axle
Alignment.
b. If belt tension does require adjustment, see
ADJUSTMENT, Deflection Adjustment. After adjust-
ing deflection, check axle alignment.
5. Install drive support arm and sprocket cover.
a. Apply LOCTITE THREADLOCKER 272 (red) to
drive support screws. Tighten screws to 20-25 ft-lbs
(27-34 Nm).
b. Tighten drive support nut to 35 ft-lbs (40-47 Nm).
