5. Tilt auger/impeller assembly forward from rear and lift clear of supporting bar on frame.
6. Remove impeller/auger drive pulley from the housing and auger drive shaft.
7. Remove shear bolts from impeller.
8. Remove auger bearings and retainers from each side of auger housing.
9. Pull auger/impeller assembly forward out of housing, freeing the drive shaft.
10. (I took the housing to a machine shop to weld the crack in the impeller housing.)
11. Mount the new impeller on the shaft and tighten shear bolts.
12. Put auger bearing retainers back on the ends of the auger shaft.
12. Move the auger into the housing, running the drive shaft back through the rear bearing.
13. Re-attach the bearings to the auger shaft and bolt through the housing to the retainers.
14. Re-attach the drive pulley on the outside back of the housing.
15. Re-hang the auger/impeller housing on motor frame crossbar.
16. Re-attach bolts holding auger/impeller housing to the motor frame.
