drive components. Always make sure the chain
adjusted within the stated specifications.
1. Check the amount of chain slack by moving the
vehicle slightly forward to gain slack at the top side of
the chain.
2. Raise the rear of the vehicle and support securely
under the mainframe. Allow the swing arm to hang at
full shock extension without touching the ground. This
establishes the tightest chain position.
3. Pull down on the chain tensioner to move it out of the
way, then measure chain deflection. It should have 1/
4"-1/2" (6-12 mm) deflection.
4. Loosen the four rear housing mount bolts (two on each
end of axle).
5. Loosen the chain adjuster locknuts.
6. Turn the chain adjusters evenly to achieve 1/4"-1/2"
(6-12 mm) chain deflection.
7. Torque the chain adjuster locknuts. Hold the adjuster
stud securely while tightening the nut to avoid
breaking the stud.
8. Torque the four rear housing mount bolts.
