MAINTENANCE

Rear Drive Chain Slack Adjustment

(Models with Concentric Drive)

Check the amount of chain slack by moving the vehicle slightly for-

ward to gain slack at the top side of the rear chain. At this point

the chain should have 3/16

″

-3/8

″

(.48 cm - .95 cm) deflection (1).

If the chain needs adjustment, use the following procedure.

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.
