securely.
Replacing Belts
To remove and replace either the auger belt or the drive
belt, follow the steps below and then proceed to the
specific steps listed under respective sub-headings.
• Disconnect the chute crank assembly at the
discharge chute end by removing the hairpin clip
and the two flat washers.
• Remove the plastic belt cover, located near the
engine, by removing the three self-tapping screws
and flat washers that secure it. See Figure 17.
Figure 17
• Remove the large shoulder bolt and washer on the
left hand side of the engine pulley. See Figure 17.
Auger Belt
• Remove the hairpin clip and flat washer from the
ferrule in order to disconnect the auger idler rod from
the brake bracket assembly. See Figure 17.
Figure 18
• Slip the auger control belt (the front belt) off the
engine pulley. See Figure 19.
• Pull the brake bracket assembly towards the cable
guide roller and unhook the auger cable “Z” fitting.

• Remove the upper bolts and lock washers which
attach the auger housing assembly to the frame
assembly using a 9/16” wrench. Refer to Figure 17.
• Separate auger housing from the frame by tilting the
housing forward and pulling up the handles.
• Using a 1/2” wrench, remove the hex screw and
belleville washer from the center of the pulley on the
auger housing. Lift the brake bracket assembly out
of the pulley groove and remove the pulley. See
Figure 20. Be careful not to lose the key.
• Remove and replace auger belt inside belt keepers.
• Reassemble pulley to auger housing with hex screw
and belleville washer (cupped side toward the
pulley). Make sure key is in place on shaft and brake
puck is seated in the pulley groove.
• Reassemble belt cover and chute directional control.
Proper Adjustment: With the auger clutch lever in the
disengaged position, the top surface of the new belt
should be even with the outside diameter of the pulley.
• To adjust, disconnect ferrule from brake bracket
assembly and thread ferrule in (towards idler) to
increase tension on belt, and out to decrease tension.
NOTE: The brake puck must always be firmly seated in
the pulley groove when auger control is disengaged.
