I have my old faithful Ariens 10970,    late 70's   I believe I broke a shearbolt end of last season.

here's my scenario: 2 piece rake(auger) right side of rake from center resevoir turns but once there is a snow load it stops and clogs.

Upon inspecting I noticed a broken bolt within the auger on the shaft, assuming that is a shear bolt..

my problem: the shear bolt did just that, sheared off, how can i remove the bolt that broke off in the shaft,flush with the shaft, without drilling

and is that shearbolt standard size on all old ariens.

any insight or suggestions would be greatly appreciated!

Spray  location of shear pin hole with WD-40.  Get a hammer and a nail of similar size as the shear bolt and pound the broken shear bolt through the hole on the opposite side.  If it still doesn't move, apply some heat to the shaft near the shear pin hole.  You might get some smoke but that will likely be the grease cooking between  the auger and drive shaft.  Don't use too much heat.  You don't want to damage seals associated with the drive system.  Not sure about your machine but there usually should be a couple of grease fittings on each side of the auger gear case.  Ensure you put some grease through them to lubricate the auger shaft.   Shear bolts/pins are of a specific size and hardness.  Keep your portion of the shear bolt you punched out and take it to any hardware store and tell them you need shear bolts of the same diameter.
