TRACTION DRIVE BELT
If your snow thrower will not move forward,
check the traction drive belt (see second
figure on page 19) for wear (Check other
causes also in the Trouble Shooting Points
section). If the traction drive belt needs to be
replaced, proceed as follows:
• Disconnect the spark plug wire.
• Remove the belt cover (see second fig­
ure).
• Loosen the belt guide and pull away from
auger drive pulley (see second figure on
page 19).
• Remove auger drive belt from auger pul­
ley (see second figure on page 19).
• Pull the traction drive belt idler pulley
away from the traction drive belt (see
second figure on page 19).
• Remove the traction drive belt.
• Position new traction drive belt onto trac­
tion pulley.
• Pull idler pulley away from belt, allowing
belt to be positioned onto auger pulley.
• Check clutch control cable adjustment,
see page
• Reconnect the spark plug wire.
TO ADJUST THE BELT GUIDE
• Disconnect the spark plug wire.
• Remove the belt cover (see third figure
on page 19).
• Engage the auger drive clutch lever.
Measure the distance between the belt
guide and the belt (see figure below). The
distance should be 1/8".
If adjustment is necessary, loosen the
belt guide mounting bolt. Move the belt
guide to the correct position and tighten
the mounting bolt.
Reinstall the belt cover.
Reconnect the spark plug wire.
TO ADJUST THE FRICTION WHEEL
If the snow thrower will not move forward,
you need to check the traction drive belt, the
traction drive cable or the friction wheel. If
the friction wheel is damaged, it will need to
be replaced (see the To Replace Friction
Wheel paragraph on page 21). If the friction
wheel is not worn, check the adjustment, as
follows:
• Disconnect the spark plug wire.
• Drain the gasoline from the gas tank.
• Stand snow thrower on the auger housing
end.
• Remove the bottom panel (see figure be­
low).
