Flange Bearing

Removed belt cover.
Removed 2 bolts securing auger assembly to power unit.
Remove auger belt.
Remove auger belt pulley
Remove 2 bolts and 2 nuts securing flange bearing. It is helpful to have a deep well socket and a long extension to reach the bolt heads loacated behind the auger and impeller.
Replace flange bearing and re-assemble. 30 minute job at most.

Had to separate the snowblower frame assembly from the auger housing, then remove the impeller pulley, remove the bearing portion of the old flange bearing that remained on the impeller shaft, use the 36 mm socket and dead blow hammer to gently pound the new flange bearing onto the shaft, clean the damaged threads with a 5/16 -18 die, then secure the flange bearing with the new nuts and reassemble the snowblower.

1.split impeller housing from main frame
2 remove impeller pulley
3 remove impeller/auger
4 remove flange bearing and replace with new
5 replace impeller/auger
6 replace impeller pulley, install belt, mesh housing to frame

Removed the entire auger assembly, blades, drive shaft etc. from blower. Skid plate had to be removed as well to access underneath and behind blade housing to remove the impeller pulley.
Impeller pulley was compromised and needed to be replaced.
Replaced impeller pulley, drive shaft & flange bearing
Put snowblower back together and it works like its brand new again.
All total time for disassembly, order parts & putting back together was a 4 day project. (remember that time period included the ordering and shipping to Alaska)
$165ish worth of parts to get a free $1200 snowblower back together, worth it.
Thank you guys for the diagrams, the easy ordering & the fast shipping!!

Disassembled, like replacing belts, removed remains of old bearing, cleaned up shaft at pulley area. Replaced defective parts and reassembled. Pretty straight forward after reading the manual. Used a tie down instead of a second person to pull auger section and power section together on re assembly. Could do it slowly and steadily while checking fit and clearance and it held sections together while I put the attachment bolts in the housing. All parts matched the originals with no problems and would use this website again .
