Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a Honda HS1132 that ran over something that made a noise and instead of breaking the shear bolts the complete auger and blower assembly now turns independently of the auger pulley. I can not see behind the blower (blade) or in front of the auger pulley. I have been searching and researching drawings, parts and forums for some clues to the issue. I can't find anything. MY GUESS: is that there is a shaft (a 2-4" shaft) that attaches the blower to the auger pulley. There must be a bolt or pin that has broken. This is a vary difficult area to see and I would need to remove the complete auger/blower assembly and housing just to get a view. Is there anyone that has a picture, drawing or knowledge of what this looks like and what could be the problem?

Trouts, That is if it's a grade 5 bolt. One more thing worth a mention, not to tighten down any shear bolt but rather stop at the point where it can still spin some. Otherwise it takes a bit more to shear and risk something else breaking rather than the bolt. Iv'e seen bolts so tight that the tube and shaft are pressed together and that's not correct.

hirschallan, good advice, thanks. I just had to replace my first one recently, and was unsure how tight to make it. I left it a bit loose, so it could still turn.

Also, if your machine has grease fittings on the augers, use them. And maybe once a season, when you grease them, remove the shear bolts and spin the augers on the shaft. If the augers rust to the shaft, they can apparently be incredibly difficult to remove, plus the shear bolts are now useless, so you can blow an auger gearbox.

   Good point on the nut.   There's a lot of vibration in there.  When I've got them I use a self locking on the drive shaft bolt.  For the rakes just a regular nut
cranked down.   A longer bolt for the drive shaft double nutted would work.
