9. Rotate inside nut on chain tensioner until desired
chain deflection is attained.

measure distance from center of pillow blocks to
rear of chassis (Fig. 24). Difference between the
two measurements must not exceed 1/8 inch. If
difference exceeds 1/8 inch, axle is not parallel
with chassis; therefore it must be readjusted.

bottom of rider (refer to step 2).
13. Tip rider back to its normal operating position
and install chain cover..
