MAINTENANCE
Augers
• The augers are secured to the spiral shaft with two shear pins and
cotter pins. If the auger should strike a foreign object or ice jam,
the snow thrower is designed so that the pins may shear. Refer to
Figure 4.
• If the augers will not turn, check to see if the pins have sheared.
One set of replacement shear pins has been provided with the
snow thrower. When replacing pins, spray an oil lubricant into shaft
before inserting new pins.
Drive Belt Replacement
To remove and replace your snow thrower's auger belt, proceed as
follows:
1. Remove the plastic belt cover on the front of the engine by remov-
ing the two self-tapping screws.
• Drain the gasoline from the snow thrower, or place a piece of
plastic under the gas cap.
• Carefully pivot the snow thrower up and forward so that it rests on
the auger housing.
2. Remove the frame cover from the underside of the snow thrower by
removing four self-tapping screws which secure it.
3. a. Grasp the idler pulley and pivot it toward the right.
b. Roll the auger belt off the engine pulley.
c. Lift the drive belt off engine pulley.
4. Slip the drive belt off the pulley and between friction wheel and
friction wheel disc.
• Remove and replace belt in the reverse order.
Friction Wheel Removal
If the snow thrower fails to drive with the drive control engaged, and
performing the drive control cable adjustment on page 19 fails to
correct the problem, the friction wheel may need to be replaced. Follow
the instructions below. Examine the friction wheel for signs of wear or
cracking and replace if necessary
