not contact the plug accidentally (Fig. 25).
2. Remove (3) screws holding belt cover in place
and set cover aside (Fig. 32).
3. Loosen auger brake arm assembly by loosening
rear screw and removing front screw that fasten
auger brake arm assembly to frame (Fig. 33).
4. Remove idler pulley spring (Fig. 33). Let brake
arm assembly hang free but out of the way.

washers securing belt guide (Fig. 34).
6. Remove engine crankshaft screw, lock washer
and washer (Fig. 34).

around large auger/impeller pulley (Fig. 34).
Next, loop belt in front of center engine pulley,
making sure that belt is on inside of idler pulley

washer and engine crankshaft screw. Make sure
the indexing rib in the engine pulley sheave is
aligned with the indexing notch in the center
