Intermediate Frame Snowthrowers
Belt Adjustment
Auger Drive Belt
If your snowthrower will not discharge snow, check the control cable adjustment. If it is correct, then check the condition of the auger drive belt. If it is damaged or loose,replace it (see Belt Replacement in this section of the manual).
1.Disconnect spark plug wire.
2.Loosen screw (B, Figure 9) from belt cover (A). Remove belt cover (A).
3.Loosen nut (D, Figure 10) on auger idler pulley (B) and move auger idler pulley towards belt about 1/8 inch (3mm).
4.Tighten nut (D).
5.Engage auger drive clutch. Check tension on belt (opposite idler pulley). Belt should deflect about 1/2 inch (12.5 mm) with moderate pressure see Figure 11). You may have to move the idler pulley more than once to obtain the correct tension.
6.Reinstall belt cover (A, Figure 9) securing with screws (B).
7.Whenever belts are adjusted or replaced, the auger drive or traction drive controls will need to be adjusted. (see Auger Drive or Traction Drive Adjustment in this section of the manual).
8.Attach the spark plug wire.
9.Auger must stop within 5 seconds.
Traction Drive Belt
The traction drive belt has constant spring pressure and does not require an adjustment. If the traction drive belt is slipping,replace the belt. See Belt Replacement.
Note: After adjustments are complete, make sure the drive disengages when released.
