Screw

Replaced the 2 bolts and all 8 nuts. Seems ok now.
Thanks for the quick return!

Removed side cover, removed belt, removed the bolt holding pulley on shaft then removed nuts and bolts for bearing, then removed three bolts on the opposite side. The inner assembly pulls out, unscrew bolts on rubber paddles and install new parts and reassemble in the reverse order.

Pretty straight forward. Just took out the bolts and impeller, then put'em back in. I did need a 3rd hand to get 2 of the bolts back in on the 'passenger side'.

One rotor at time, however after pulling first rotor did the scraper bar.

1. Removed as much gas as I can from tank
2. Tilted snow blower back on to handle to get to bolts. Easier if on a shop table!!!
3. Shot bolts to be removed with WD40 - let it sit awhile.
4. Using a 5/8" (I think) socket I took off old scrapper
5. Used a hammer to tap off the old scrapper.
6. The housing of snow blower was slightly bent from 23years of use, so I used a 3lb hammer to carefully straighten the housing.
7. Align hole in new scrapper with mounting holes on housing and tapped into place with hammer
8. Starting from one end I put bolts into place and slightly tightened until all 3 bolts were in place
9. Tightened all bolts once in place.
10. The exploded view showing the parts on your web page helps tremendously in figuring on how to approach the job.
