CDQ Drive Belt Tension
The drive belt is a link stretch belt designed to provide
tension throughout the life of the belt. Inspect the belt
annually for proper tracking and tension. A properly
tensioned belt will turn the wheel immediately, with no
visible slippage, when power is applied. If belt needs
tensioning, see "CDQ Drive Belt Adjustment/
Replacement" on page 73.
