Chraftsman Model 944.527391 RE Auger Housing/Impreller Assembly I picked up a 2" rock in impreller it bent the impreller as when running making noise and throwing shaft trueness off I located bent part of impreller and want to remove. Suspect I need to take it out Auger Housing snow in side of blower I figured it would pull right out after taking out bolts in auger bearing ( 26) located on side of Housing. Was not sure of item 16 the bolt holding pulley if that had to be removed allowing shaft to move thru 5 Bearing assembly flange near pulley so that the whole unit could be removed and then slide off the impreller the pulley side of the unit. ?? I was puzzled with the function of 51 the roll pin and what it's function was. I want to remove impreller and straighten it out so it runs a bit more true and stops scraping the side of the auger housing I would appreciate a response as live in NS eastern canada and my luck will be big snowe storm this week?? Sunny and 50 yesterday while taking apart for reapir for next winter. Should have been playing with lawn mower!!! Any help would be appreciated. Cheers
