• 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.
