Auger Drive Belt Adjustment

Due to wear, the auger drive belt may begin to slip when the auger drive lever is engaged. To adjust the auger drive belt:

1.Perform the brake arm adjustment as described later in this section.

2.If assembling a new unit, raise the wheel drive control lever (AP, Fig. 5-9) and the auger drive control lever (AL).

3.Pull the auger drive control arm (AJ, Fig. 5-10) down completely.

4.Measure and note the length of the spring (AK, Fig. 5-10).

5.Squeeze the auger drive control lever (AL, Fig. 5-9) against the handlebar. Measure the length of the spring (AK, Fig. 5-10) again. The spring length should now measure 9/16" – 11/16". (14–17mm) longer than the measurement taken in step 4. If it does not, loosen the jam nut (AM) and turn the adjuster (AN) to increase or decrease the length of the spring. Hold the adjuster and tighten the jam nut (AM) when the correct spring length is obtained. Re-check the measurements and adjust if needed.

NOTE: 1-1/4 turns of the adjuster equals 1/16" (1.5mm) of spring extension.

Auger Drive Belt Replacement

To remove the auger drive belt:

1.Remove the bolts, flat washers, and lockwashers securing the belt cover (AB, Fig. 5-9) to the unit. Remove the belt cover.

2.Remove the two bolts securing the belt guide (AC, Fig. 5-11) to the engine. Remove the belt guide.

3.Loosen jam nut (BC) and remove bolt (BD).

4.Remove the auger drive belt (AD) from the auger drive pulley (AE).
