AUGER DRIVE CLUTCH ROD ADJUSTMENT

The auger drive clutch rod should be adjusted so that there is no slack in the rod when moved slightly from side to side. To adjust tension on the rod:

1.Loosen adjustment hex nuts (Figure 22).

2.Tighten top hex nut while holding rod. Tighten just until slack in rod is removed. Be careful not to move idler rod lever when adjusting clutch rod tension.

3.Tighten lower hex nut securely.

WARNING

Do not over-tighten, as this may lift the idler rod lever and cause auger drive to be engaged without depressing the Auger Control.

4.Start unit and check auger. Auger must not be engaged unless Auger Control is depressed.

5.With engine running, fully depress Auger Control, the auger should engage and run normally.

6.Release Auger Control. Auger must stop within 5 seconds.

7.If auger does not operate properly, stop engine and recheck clutch rod adjustments.

8.If clutch rod is properly adjusted, auger drive belt ten- sion may require adjustment. See "Adjusting Auger Drive Belt" on next page.

DRIVE BELT ADJUSTMENT

The snowthrower is equipped with two drive belts locat- ed just in front of the engine under the belt cover. Figure 23 shows both belts and idler pulleys. The belt nearest the engine is the unit traction drive (wheels) belt. The belt farthest from the engine is the auger/ impeller drive belt.

The traction drive belt has constant tension provided by a spring-loaded idler pulley arm, and is non-adjustable. This belt rotates whenever the engine is running, and provides power to the traction drive disc, which also rotates constantly while the engine is running.

The auger drive belt tension may be adjusted by moving the auger drive idler pulley. See "Adjusting Auger Drive Belt’ on next page.
