Murphy's Law is nailing me this week. My beloved Airens 1032 1980? is shot. I found a 1972 Toro 832 that hadn't been used for 10 years...runs great however I was worried about the drum auger and no shear bolts as I went through a couple shear bolts a season with the Airens. Well today (second time I used the Toro) I scooped a rock and now the left auger isn't working. The right auger and the impeller work fine. I called Toro and explained, they said its probably the Carriage Bolts #8. I think its the HH Screw #54. Any help? Also, I need to lube the gear box, whats the oil I should use? Thanks, Abby's Guide has been a savior today. Still missing the Airens.

i also use 90 wt,

ADK: I have the same exact Toro 832 and my RIGHT side auger isn't working but  the left is. I was wondering how to take the auger apart to fix it, specifically the drive shaft in the middle of the auger.

PLEASE RSVP if you can help.

Thanks

P.S.- I was also wondering what grade of bolt to use- 5? 8?.

Can these be replaced with a higher grade to prevent them shearing off or will that put too much stress on the drive shaft?

Soft bolts only (5).  They have a job to do.  That job is to protect your gear case/gears.  If you're going through a lot of shear bolts, you'd be better off figuring out why and correcting that problem.

Grade 5 bolts are even to strong.. shear pins or bolts usually have cuts in them or are made of #3 strength or less..

my suggestion is to use exactly what toro is suggesting... I only use factory toro shear bolts on "drum style" augers
