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 19).

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.

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
20 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.

CAUTION

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