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

ENGAGED 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

19. Install the bolts (1) on each side of the
bottom 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.

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
Maintenance 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
replacement belt available from an
authorized service center.
6. Install the new traction drive belt (13) onto
the traction drive pulley (14) and onto
engine pulley (15).
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
secure with the e−ring (17) removed earlier.
10. (Figure 32) The bottom of the swing plate
(20) must be positioned between the
alignment 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).
11. (Figure 19) Install and adjust the auger
drive belt (4). See "How To Remove The
Auger Drive Belt" in the Maintenance section.
12. Adjust the belt guide (9). See "How To
Adjust The Belt Guide" in the Maintenance
section.
13. (Figure 22) Install the bottom panel (2).
14. Tighten the bolts (3) on each side of the
bottom panel (2).
15. (Figure 18) Install the belt cover (1). Tighten
screw (2).
16. Check the adjustment of the cables. See
"How To Check And Adjust The Cables" in
the Maintenance section.
17. Connect the spark plug wire.
How To Adjust The Belt Guide
1. Disconnect spark plug wire.
2. (Figure 18) Remove screw (2). Remove the
belt cover (1).
3. (Figure 1) Engage the auger drive lever (5).
4. (Figure 23) Measure the distance between
the belt guide (2) and auger drive belt (3).
The correct distance (4) is 1/8 inch (3 mm).
5. If an adjustment is necessary, loosen the
mounting bolt for the belt guide (2). Move
the belt guide (2) to the correct position
(4). Tighten the mounting bolt for the belt
guide (2).
6. (Figure 18) Install the belt cover (1). Tighten
screw (2).
7. Connect the spark plug wire.

How To Adjust Or Replace The Friction
Wheel
How To Check The Friction Wheel
If the snow thrower will not move forward, check
the traction drive belt, the traction drive cable or
the friction wheel. If the friction wheel is worn or
damaged, it must be replaced. See "How To
Replace the Friction Wheel" in this section. If the
friction wheel is not worn or damaged, check as
follows.
1. (Figure 1) Remove the gas from the gas
tank. Stand the snow thrower up on the front
end of the auger housing (4).
WARNING: Drain the gasoline
outdoors, away from fire or flame.
2. Disconnect the spark plug wire.
3. (Figure 22) Remove the bolts (1) on each
side of the bottom panel (2).
4. Loosen the bolts (3) on each side of the
bottom panel (2).
5. Remove the bottom panel (2).
6. (Figure 1) Position the shift speed lever (6)
in the lowest forward speed.
7. (Figure 24) Note the position of the friction
wheel (4). The correct distance "A" from the
right side of the friction wheel (4) to the
outside of the motorbox is as follows:
Tire Size Distance "A"
12 and 13 inch 4-1/8" (10.5 cm)
16 inch 4-5/16" (10.95 cm)
If the friction wheel (4) is not in the correct
position, adjust as follows.
How To Adjust The Friction Wheel
1. (Figure 1) Position the shift speed lever (6)
in the lowest forward speed.
2. (Figure 9) Loosen hex jam nut (9) on speed
select rod (2). Remove ball joint (6) from
shifter rod (7).
3. (Figure 24) Move the friction wheel (4) to
the correct position.
4. (Figure 9) Turn the adaptor (10) until the
ball joint (6) is aligned with the mounting
hole in the shifter rod (7). When aligned,
attach the ball joint (6) to the shifter rod (7).
5. (Figure 22) Install the bottom panel (2).
6. Install the bolts (1) on each side of the
bottom panel (2).
7. Tighten the bolts (1) and bolts (3) on each
side of the bottom panel (2).
How To Replace The Friction Wheel
If the friction wheel is worn or damaged, the
snow thrower will not move forward. The friction
wheel must be replaced as follows.
WARNING: Do not lubricate the
disc drive plate or the friction
wheel.
1. (Figure 1) Remove the gas from the gas
tank. Stand the snow thrower up on the front
end of the auger housing (4).
WARNING: Drain the gasoline
outdoors, away from fire or flame.
