AUGER DRIVE CLUTCH CABLE ADJUSTMENT

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

1.Loosen adjustment hex nut (Figure 21) by holding the adjusting flats and turning adjustment hex nut .

2.Tighten adjustment screw by turning adjustment flats and holding screw. The adjustment screw is a phillips screw and the head can be held or turned by inserting a screwdriver through the auger drive clutch cable spring. Tighten just until slack in cable is removed.

WARNING

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

3.Tighten 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 cable adjustments.

8.If clutch cable is properly adjusted, auger drive belt tension 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 22 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.
