I have a snapper snow blower Model #155223. The drive is not

Customer Question

I have a snapper snow blower Model #155223. The drive is not working, I pulled the cover off of the bottom and I can move the axle but the gear spins freely from the axle that is suppose to catch onto the larger gear. There is a hole on each side of this gear (which looks like pins or screws would go in to hold it in place on the axle). Need some help, because I cannot find how to address this anywhere in the manual.

Thanks.

Thank you for choosing Just Answer, my name is XXXXX XXXXX I will do my best to help you find the answer you need to resolve your problem.

Can you check your model number again. Every combination that I put in for it does not come up.

I am pretty sure I know what your problem is though. The larger gear is held in place by a woodruff key, or a half moon key. It sits in the axle and keys to a slot in that large gear. If you can slide the gear to the side (it may be help in place by an E-clip or roll pin) you will see what I am talking about.
The bad news is that snapper uses a very specialized key that must be bought from a snapper dealer. The good news is that they are fairly inexpensive. It is just a hassle sometimes to get to a dealer.

Thanks Jon. I just needed the name of the part that I need to replace. I have a snapper dealer in town and so I will ask them for a woodruff key (or half-moon key). I figured it was going to be an easy fix, I just dfidn't know what to call the part that I am looking for.

Thanks,
Keith

It is called a woodruff key and shaped like a half moon, they should know what you are talking about if you explain it to them as well as you explained it to me
