Single stage snow thrower shear pins and other Q
Posted January 08, 2017 - 02:35 PM
Last month the wife and I made a field trip down to PA to visit Rick (Blackjackjakexxix Bolens Parts) to pick up a single stage snow thrower. It was great finally meeting him and seeing all the great toys he has. This morning I finally started preping it for service. The question I have is about the shear pin, or is it a roll pin? There is both a roll pin and a common 1/4" nut and bolt next to each other. I am going to see if the hardware store has a normal shear pin in that size. Do I just rely on the roll pin?
As a side note, does anyone use drift cutters or sheet metal extensions? Are they worth it?

The "shear pin"on these was a roll pin although I do remember it being slightly different in the way it was manufactured , it almost seemed like it had extra material in the center if I remember correctly
Think the part number was 1891696 off the top of my head

Must have been thinking about another pin, this one looks like a regular pin , I actually have one instock I forgot about LOL
My notes show it being a regular roll pin on this application

I have extensions on my blower don't know if they are factory made or homemade . On mine they are helpful because the width of rear wheels with the weights is wider than the blower and without them the weights hit the edge of unblowen snow and knocks it down making in necessary to make another pass to clean it up.

They made extensions for the large frame blowers not sure about for the tube frame blowers. They are helpful as you mentioned.

I use a 1/4" grade three bolt for the shear pin. I pick up a handful at Tractor Supply for less than a buck. They are soft and shear just fine. You could also cut a notch in them if you were concerned about them shearing properly. I also have the extensions on the blower. I've also got drift cutters that bolt onto single stage snow caster. Helps when those snow banks get high
