Adjustments - Craftsman C459-527870 Operator's Manual

WARNING: NEVER attempt to make any adjust-
ments while the engine is running, except where
specified in the operator's manual.
Shift Rod
If the full range of speeds (forward and reverse) cannot be achieved,
refer to Figure 14 and adjust the shift rod as follows:
1. Looking underneath the handle panel, note which of the three holes
in the shift lever the ferrule is inserted into. Also note the direction
of insertion. Then remove the internal cotter pin and flat washer
from the ferrule and withdraw the ferrule from the shift lever. See
Figure 14.
2. Place shift lever in sixth (6) position or fastest forward speed.
3. Push shift rod and shift arm assembly down sharply, as far as it will
go to put the drive into the fastest forward position.
4. As necessary, rotate the ferrule up or down the shift rod until the
ferrule lines up with the hole from which it was earlier removed. See
Figure 14.
5. From the direction noted earlier, insert the ferrule into the proper
hole.
6. Reinstall the washer and the internal cotter pin.
Drive Control
Refer to the Final Adjustment section of the Set-Up instructions to
adjust the drive control. To further check the adjustment, proceed as
follows:
1. Drain the gasoline out of your snow thrower's engine, and place a
piece of plastic film under the gas cap to avoid spillage.
2. Tip the snow thrower forward, allowing it to rest on the auger
housing.
3. Remove the frame cover underneath the snow thrower by removing
the self-tapping screws. See Figure 15.
4. With the wheel drive control released, check if there is clearance
between friction wheel and drive plate in all positions of the shift
lever. See Figure 16.
5. With the drive control lever engaged, check if the friction wheel
solidly contacts the drive plate. See Figure 16. If not, adjust as
follows:
a. Loosen the jam nut on the traction drive cable and thread the
cable in or out as necessary.
b. Retighten the jam nut to secure the cable when correct adjust-
ment is reached.
6. Reassemble the frame cover.
NOTE: If you placed plastic film under the gas cap earlier, remove it
now.
