Impeller Control Cable Adjustment
For Brake to function properly, there must ALWAYS be
some slight, noticeable slack in the Control Cable Inner
Wire when the Impeller Clutch Ball is disengaged
(lowered position). This allows Extension Spring to pull
Idler Arm/Brake, braking Belt. Bail should travel 6-3/4 to
7-1/4“ (17.1-18.4 cm) before contacting Handlebar. If
Brake does not stop Impeller within 5 seconds of
releasing Impeller Clutch Bail, Inner Wire slack must be
adjusted.
A properly adjusted Clutch must show a noticeable
increase in resistance (caused by stretch of Control
Cable Spring) before Impeller Clutch Bail contacts
Handlebar. At factory adjustment, increase occurs 1 to
1-1/2" (2.5-3.8 cm) from Handlebar. As Drive Belt seats
and wears, increase in resistance will occur closer to
Handlebar contact. If no resistance occurs. Inner Wire
slack must be adjusted.
To adjust Inner Wire (Figure 12);
• Use Adjusting Nuts on Control Cable to remove
almost all slack in Inner Wire.
IMPORTANT: If there is still no resistance, the Idler
Position must be adjusted.
Idler Position Adjustment
For proper operation, the Idler must be as close as
possible to the Drive Belt when the Impeller Clutch Bail
is disengaged (lowered position), but not so close that it
causes Impeller rotation. To adjust the Idler position
(Figure 13):
1. Shut off engine, allow to cool, and remove Cowl.
ROTATING PARTS can result in
serious injury or death. ALWAYS
keep hands and feet away. DO NOT
wear loose clothing or scarves that
may get caught in rotating parts.
2. Ensure Control Cable Inner Wire has slack when
Impeller Clutch Bail is disengaged (lowered
position).
3. Ensure Belt Fingers are properly adjusted (see
Drive Belt Replacement).
4. Loosen Idler hardware, reposition Idler along Slot in
Idler Arm, and tighten hardware.
5. Check for proper Impeller Clutch Bail resistance.
NOTE: It may be desirable to leave extra slack in the
Control Cable Inner Wire so Bail resistance is not
uncomfortably strong when held up against the
Handlebar.
6. Start engine and ensure Impeller does not rotate
when Impeller Clutch is disengaged.
7. Repeat the above steps until proper adjustment is
achieved.
IMPORTANT: If adjustment cannot be achieved, the
Drive Belt must be replaced.
8. Replace Cowl.
