Idler Pulley Rod
After the belt tension has been adjusted, if the belt is excessively stretched, you may need
to adjust the idler pulley rod. This can be checked easily.
With the engine off and the clutch control bail disengaged, shift the gear selection
handle to each forward mode. If the indicator bracket touches the idler pulley rod
with the clutch control bail disengaged, then an adjustment is necessary.
1. Disconnect and ground the spark plug wire against the engine.
2. Remove the belt cover as described under Belt Replacement earlier in this
section.
3. Remove the cotter pin and spring washer from the idler pulley rod. See
Figure 31.
