Adjusting The Auger/Impeller Drive Belt; Replacing The Auger/Impeller Drive Belt - Toro 38086 Operator's Manual

Adjusting the Auger/Impeller
Drive Belt
An auger/impeller drive belt that slips results in decreased
snowthrowing performance and requires either an
adjustment or a new belt.
DANGER
POTENTIAL HAZARD
Improper adjustment may cause injury if the
auger/impeller turns when disengaged.
WHAT CAN HAPPEN
The rotating impeller or auger can cut off or
injure fingers or hands.
HOW TO AVOID THE HAZARD
Keep your face, hands, feet, and any other part
of your body or clothing away from concealed,
moving, or rotating parts.
Ensure that the impeller brake arm clearance is
maintained.
Do not adjust the auger/impeller drive belt too
tight because it may cause the auger/impeller to
turn when the control lever is in the disengaged
position. If this occurs, decrease belt tension.
After five to ten hours of snowthrower operation with a
new auger/impeller drive belt, check the belt for
proper tension.
1. Pull the wire off of the spark plug and ensure that the
wire does not contact the plug.
2. Check the adjustment per steps 5 through 7 of
Installing the Auger/Impeller Drive Control Linkage
on page 9. Make any needed adjustments.
3. Check the belt tension by operating the auger.
4. If belt still slips, replace the belt.
5. If the auger and the impeller rotate while the engine
runs and the auger/impeller control lever is
disengaged, immediately stop the engine and bring
the snowthrower to an Authorized Service Dealer for
service.
IMPORTANT:
Do not operate the snowthrower if the
auger and the impeller rotate when the auger/impeller
control lever is disengaged.
Replacing the Auger/Impeller
Drive Belt
When the auger/impeller drive belt (Fig. 28) becomes
worn, oil–soaked, or otherwise damaged, replace the belt.
After five to ten hours of snowthrower operation with a
new auger/impeller drive belt, check the belt to ensure
the proper belt tension.
1. Pull the wire off of the spark plug and ensure that it
does not contact the plug (Fig. 23).
2. Remove the three screws that hold the belt cover in
place and set the cover aside (Fig. 26).
1. Upper belt cover
3. Loosen the auger brake arm assembly by loosening a
rear screw and removing the front screw that fasten the
auger brake arm assembly to the frame (Fig. 27).
