Kraig - I'd be interested to know and see some pics of how your thrower is holding up. I seem to recall the small side of the small sprocket would be the side that cut mostly into the mount bracket. Even a steel washer larger than the diameter of the small side of the sprocket would help avoid this "cutting" effect, and probably hold up quite awhile. <!-/quote-!><hr size=0></blockquote>

Harry, I too noticed that wear on my QA42 many years ago when I refurbished it. I also added shims (don't recall what they were made of) to help reduce wear. I got my 125 all ready for winter duty one day last week. I suppose I should check it to see how the shim mod is holding up...<!-/quote-!><hr size=0></blockquote>

Ok guys - snow season is coming up and I'm certain alot of you are getting your Throwers all ready and warmed up (as Joseph S has with his 1450 and QA42A). I'm wondering if any of you have made any adjustments/alternations to the small chain sprocket bracket/assembly? I discovered over time the sides of the small sprocket would cut into the "cast" mounting bracket, and eventually cut into the area housing the needle bearings. The sprocket slides side to side when the thrower is raised/lowered which pulls or pushes the sprocket into the bracket, resulting in this wear if the thrower is running. I used to install brass shims to help avoid this wear and keep the small sprocket in alignment with the large sprocket on the auger. Just wondering if anyone else has been doing this, or if anyone noticed this wear and may have addressed it with different methods, to avoid replacing their small sprocket bracket.<!-/quote-!><hr size=0></blockquote>
