Drive Belt - Craftsman 247.88779 Manual De Instrucciones

Replacing belts
NOTE: There are two belts on this snow thrower: an auger belt and
drive belt. It is recommended that both belts be replaced at the same
time.
1. Remove the spark plug wire from spark plug and ground it against
the engine to prevent accidental starting.
2. Run the engine until the fuel tank is dry to prevent gasoline leakage
when replacing belts.
WARNINg
Perform belt maintenance outdoors as some gas may possibly leak
from the carburetor.
3. Remove the self-tapping screw shown in Figure 17, and press the
plastic tabs to release the belt cover. Pull the belt cover up and out
from around the engine and chute assembly. Set it aside and save.
Auger belt
IMPORTANT: Because gas could leak from the carburetor at this
point, the engine should have been run until the fuel tank was dry, as
previously instructed.
1. Tip the snow thrower up and forward so that it rests on the auger
housing. Remove the belt keeper as called out in Figure 19. Return
the snow thrower to its upright position to complete the following
steps.
2. Slip the front auger belt off of the engine pulley, pushing it forward
and rolling in off of the pulley. See Figure 18.
3. Squeeze the auger control handle to release the auger brake,
which is the tab that holds the belt onto the auger pulley. Remove
the belt.
4. Replace with new belt after replacing the drive belt.

Drive belt

NOTE: Replace the drive belt before reassembling the new auger belt.
1. Tip the snow thrower up and forward so that it rests on the auger
housing.
IMPORTANT: Because Gas could leak from the carburetor at this
point, the engine should have been run until the fuel tank was dry, as
previously instructed.
2. Remove the spring that connects the transmission to a bolt on the
engine frame. See Figure 19.
NOTE: It may be easier to first remove the flange lock nut, then use
needle-nosed pliers to firmly grip spring and remove from bolt.
