Rear Drive Chain Tension Inspection - Standard Swingarm

Rear drive chain tension must be measured with the swingarm in the position shown below in Ill.1. to ensure accu-
rate measurement.
NOTE: On models with concentric swingarm (all rear chain drive except Xplorer and Xpress 300), chain tension
can be measured at any point in the swingarm arc. It is not necessary to compress the suspension on concentric
models. Refer to following page for drive chain adjustment on models with concentric swingarm.
CAUTION:
S Never adjust or operate the vehicle with the rear drive chain too loose or too tight as severe damage
to the transmission and drive components can result.
S Check the amount of chain slack by moving the vehicle slightly forward to gain slack at the top side
of the rear chain.
S Collapse the suspension by using an adjustable (buckle type) trailer tie down.
S Fasten the strap around the axle and rear bumper tube. Tighten until a straight line (A) can be drawn
from the axle to the transmission output shaft intersecting the swing arm pivot.
S If the chain needs adjustment, use the following procedure.

IMPORTANT: On models with standard swingarm (non-concentric) suspension
must be compressed as shown to check drive chain tension.
