NOTE: When the auger drive belt is adjusted or replaced, check and adjust the cable.
How To Adjust The Traction Drive Cable
1.Remove the gas from the gas tank. Stand the snow thrower up on the front end of the auger housing.
WARNING: Drain the gasoline out- doors, away from fire or flame.
2.(Figure 22) Loosen the bolts (3) on each side of the bottom panel (2).
3.Remove the bottom panel (2).
4.(Figure 16) Disconnect the “Z” fitting (1) from the traction drive lever (2).
5.(Figure 27) Slide the cable boot (3) off the cable adjustment bracket (4).
6.Push the bottom of the traction control cable (5) through the cable adjustment bracket (4) until the “Z” hook (6) can be re- moved.
7.Remove the “Z” hook (6) from the cable adjustment bracket (4). Move the “Z” hook
(6) down to the next adjustment hole.
8.Pull the traction control cable (5) up through the cable adjustment bracket (4).
9.Put the cable boot (3) over the cable ad- justment bracket (4).
10.(Figure 16) Install the “Z” fitting (1) to the traction drive lever (2).
11.(Figure 15) To check the adjustment, de- press the drive lever and check the length “A” of the drive spring (7). In correct adjust- ment, the length “A” of the drive spring (7) is as follows:
minimum 3 inches (76 mm.) maximum
12.(Figure 22) Install the bottom panel (2).
13.Tighten the bolts (3) on each side of the bot- tom panel (2).
How To Adjust The Belts
The belts will stretch during normal use. If you need to adjust the belts due to wear or stretch, proceed as follows.
How To Adjust The Auger Drive Belt
If the snow thrower will not discharge snow, check the adjustment of the auger drive cable. See “How To Check And Adjust The Cables” in the Maintenance section. If the adjustment is correct, then check the condition of the auger drive belt. If the auger drive belt is damaged, replace the auger drive belt. See “How To Re- place The Belts” in the Maintenance section. If the auger drive belt is loose, adjust as follows.
1.Disconnect the spark plug wire.
2.(Figure 18) Remove screw (2) from belt cover (1). Remove the belt cover (1).
3.(Figure 19) Loosen the nut (2) on the idler pulley (3) Move the idler pulley (3) 1/8 inch toward the auger drive belt (4).
4.Tighten the nut (2).
5.(Figure 21) Depress the auger drive lever. Check the tension on the auger drive belt
(4). In correct adjustment, the auger drive belt (4) will deflect 1/2 inch (5) with moder- ate pressure. If the adjustment is not correct, repeat the adjustment.
6.(Figure 18) Install the belt cover (1). Tighten screw (2).
7.Check the adjustment of the auger drive cable. See “How To Check And Adjust The Cables” in the Maintenance section.
8.Attach the spark plug wire.
Traction Drive Belt
The traction drive belt has constant spring pres- sure and does not require an adjustment. If the traction drive belt is slipping, replace the belt.
See “How To Replace The Belts” in the Mainte- nance section.
How To Replace The Belts
The drive belts are of special construction and must be replaced with original factory replace- ment belts available from your nearest autho- rized service center.
Some steps require the assistance of a second person.
How To Remove the Auger Drive Belt
If the auger drive belt is damaged, the snow thrower will not discharge snow. Replace the damaged belt as follows.
1.Disconnect the spark plug wire.
2.(Figure 22) Remove the bolts (1) on each side of the bottom panel (2).
3.Loosen the bolts (3) on each side of the bot- tom panel (2).
4.Remove the bottom panel (2).
5.(Figure 18) Remove screw (2) from belt cover (1). Remove the belt cover (1).
6.(Figure 19) Loosen the belt guide (9). Pull the belt guide (9) away from the auger drive pulley (10).
7.Pull the idler pulley (3) away from the auger drive belt (4) and slip the auger drive belt
(4)off of the idler pulley (3).
8.Remove the auger drive belt (4) from the engine pulley (11). To remove the auger drive belt (4), the engine pulley (11) may have to be partially rotated.
9.(Figure 20) Remove the top four bolts (21) that hold together the auger housing (22) and the motor box (23). Loosen the bottom two bolts (24). The auger housing (22) and the motor box (23) can now be split apart for removal of the belt.
10.(Figure 19) Remove the old auger drive belt (4) from the auger drive pulley (10). Replace the auger drive belt (4) with an original factory replacement belt available from an authorized service center.
11.Install the new auger drive belt (4) onto the auger drive pulley (10).
NOTE: To assemble the auger housing
(22)to the motor box (23), have someone hold the auger clutch lever in the EN- GAGED position. This will move the idler arm and pulley (3) enough to allow the auger drive pulley (10) to move back into position.
12.Assemble the auger housing (22) to the motor box (23) with the four bolts (21) that were removed in step 9. Tighten the bottom two bolts (24).
13.Install the auger drive belt (4) onto the en- gine pulley (11).
14.Slip the auger drive belt (4) under the idler pulley (3).

19.Install the bolts (1) on each side of the bot- tom panel (2).
20.Tighten the bolts (1) and bolts (3) on each side of the bottom panel (2).
21.Check the adjustment of the cables. See “How To Check And Adjust The Cables” in the Maintenance section.
22.Connect the spark plug wire.
How To Remove the Traction Drive Belt
If the snow thrower will not move forward, check the traction drive belt for wear or damage. If the traction drive belt is worn or damaged, replace the belt as follows.
1.Disconnect the spark plug wire.
2.Remove the auger drive belt. See “How To Remove The Auger Drive Belt” in the Mainte- nance section.
3.(Figure 19) Remove the e-ring (17) from one end of the swing plate axle rod (18). Remove the swing plate axle rod (18) to allow the the swing plate to pivot forward.
4.Remove the traction drive spring (16).
5.Remove the old traction drive belt (13) from the traction drive pulley (14) and from the engine pulley (15). Replace the traction drive belt (13) with an original factory re- placement belt available from an authorized service center.

7.Make sure the traction drive idler pulley
(12)is properly aligned with the traction drive belt (13).
8.Attach the traction drive spring (16).
9.Install the swing plate axle rod (18) and se- cure with the
10.(Figure 30) The bottom of the swing plate
(20)must be positioned between the align- ment tabs (19). Make sure the swing plate
(20)is properly secured.
NOTE: If the drive will not engage after the traction drive belt has been replaced, then check to make sure that the swing plate is positioned between the alignment tabs (19).
