•Separate the auger housing from the frame assembly 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. Be careful not to lose the key. See Figure 18.

•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 the 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.
