9. (Figure 22) 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

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.

gine pulley (11).
14. Slip the auger drive belt (4) under the idler
pulley (3).
15. Adjust the auger drive belt (4). See "How To
Adjust The Auger Drive Belt" in the Mainte-
nance section.
16. Adjust the belt guide (9). See "How To Ad-
just The Belt Guide" in the Maintenance sec-
tion.

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.
6. Install the new traction drive belt (13) onto
the traction drive pulley (14) and onto en-
gine 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 se-
cure with the e- -ring (17) removed earlier.
10. (Figure 32) 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).
11. (Figure 21) 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 Ad-
just The Belt Guide" in the Maintenance sec-
tion.
13. (Figure 24) Install the bottom panel (2).
14. Tighten the bolts (3) on each side of the bot-
tom panel (2).
15. (Figure 20) 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 20) Remove screw (2). Remove the
belt cover (1).
3. (Figure 1) Engage the auger drive lever (5).
4. (Figure 25) Measure the distance between
the belt guide (2) and auger drive belt (3).
The correct distance (4) is 1/8 inch (3.175
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 20) 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 out-
doors, away from fire or flame.
2. Disconnect the spark plug wire.
3. (Figure 24) Remove the bolts (1) on each
side of the bottom panel (2).
4. Loosen the bolts (3) on each side of the bot-
tom panel (2).
5. Remove the bottom panel (2).
6. (Figure 1) Position the shift speed lever (6)
in the lowest forward speed.

7. (Figure 26) Note the position of the friction
wheel (4). The correct distance "A" from the
right side of the friction wheel (4) to the out-
side 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 26) Move the friction wheel (4) to
the correct position.against the snap ring
(1).
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 24) Install the bottom panel (2).
6. Install the bolts (1) on each side of the bot-
tom 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.

tank. Stand the snow thrower up on the front
end of the auger housing (4).
WARNING: Drain the gasoline out-
doors, away from fire or flame.
2. Disconnect the spark plug wire.
3. (Figure 30) Remove the fasteners that se-
cure the left wheel (10). Remove the left
wheel (10) from the axle (11).
4. Remove the bolts (1) on each side of the
bottom panel (2).
5. Loosen the bolts (3) on each side of the bot-
tom panel (2).
6. Remove the bottom panel (2).
7. (Figure 31) Remove the fasteners that se-
cure the drive sprocket (12) to the axle (11).
8. Remove the right wheel, axle (11), and drive
sprocket (12).
9. (Figure 32) Remove the four bolts (16) that
hold the bearings (7) on each side of the
hex shaft (8).
10. (Figure 33) Remove the hex shaft (8) and
