Auger Belt
• Remove the cotter pin and washer from the ferrule
in order to disconnect the auger idler rod from the
brake bracket assembly. See Figure 19.
• Slip the auger control belt (the front belt) off the
engine pulley.
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. See Figure 18.
• 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
bell 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 20.
• Remove and replace auger belt inside belt keepers.
• Reassemble pulley to auger housing with hex
screw and bell washer (cupped side toward the
pulley). Make sure key is in place on shaft and
brake puck is seated in the pulley groove.
Figure 20
• 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.
NOTE: The brake puck must always be firmly seated in
the pulley groove when the auger control is in the
disengaged position.
Drive Belt
• Unhook the extension spring from the belt cover
plate. See Figure 21.
• Remove drive belt from the engine pulley and
bottom drive pulley. Refer to Figure 21.
• Replace belt and reassemble in reverse order.
• Reassemble the two halves of the unit hooking the
lower portion of the auger housing over the
stationary shoulder bolts in the frame assembly.
