Cable Lubrication
• Lubricate the traction drive cable, shift cables,
throttle cable, and brake cable where cable enters
sheathing with a multi-purpose aerosol lubricant.
• Spray lubricant into the cable housing while work-
ing the cable back and forth a few times. Lubricate
more frequently in dry and dusty environments.
Adjusting Traction Drive Cable
NOTE: When properly adjusted, the traction drive lever
increases cable tension when the lever is parallel to the
handlebar grip.
1. See Figure 4-6. Locate traction drive cable (A)
along right handlebar.
Figure 4-6. Traction Drive Cable
2. Rotate center portion of in-line adjuster (B) clock-
wise while holding in-line adjuster ends stationary
to expand in-line adjuster and remove cable slack.
Adjusting Shift Cables
The shift cables require adjustment if there is excessive
play in the wheel speed lever, or if the lever no longer
aligns with the wheel speed label.
NOTE: One cable may need to be tensioned and the
other cable loosened to realign the lever.
1. See Figure 4-7. Locate shift cable adjustment nuts
(A) on the shift lever end of the cable.
Figure 4-7. Shift Cable
2. Loosen one of the cable jam nuts (B) using two
13 mm wrenches.
3. Pull down on the cable to remove slack and tighten
the cable adjustment nut to maintain cable tension.
NOTE: Do not over tighten the cable. Over tightening will
create a spongy feel in the shift lever.
