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

Hello all,

New member here. I seem  to be snapping alot of drive shaft shear pins. These are the pins that are holding the wheels to the shaft. I'm getting the pins from Home Depot because the snowblowers place doesn't have the size I need. I think it's  3/16". Can any suggest why I keep snap these pins.

Thanks

Hi borat,

Would using a stronger bolt cause any internal damage to gear box or anything else. I'm not to knowledgable about the inner working of the snowwblower.

I can't see how it could. 

The wheels are the only source of resistance.  If they slip, they slip.  So what?  If the machine is put up against a wall and allowed to destroy itself, there may be a possibility that a chain could break but I doubt that would happen.   Maybe others might know something that I'm unaware of but I solved my problem with a grade 10 bolt and never experienced any issues as a result.   If you want to continue replacing bolts, go with the grade 5.  If you don't want to be doing that, use a grade 10. 

My thinking is the pins he was using were grade 2, so grade 5 might be good enough.
