TE C/S sprocket question

I bought a new C/S sprocket at the dealer the other day and upon close examination, the "shoulder" on the back side of it that goes toward the transmission is .070" thinner than the other two that I have.

This would allow the sprocket to 'float' in and out between the case and the circlip. Is this OK?

I suppose the sprocket will self center, but it makes me a little nervous that the circlip is not snugged up against the sprocket like normal. I vaguely remember seeing this on bikes in the past...

Can appreciate your apprehension, and I don't know if it's officially "right" or not, but had the same issue on my KTM's and never had any issues with the counter shafts wearing or anything like that. Used C/S products for years and hand nothing but good luck with their products. I tend to belive a little "float" is probably a good thing.

I've also had experience with this exact same width problem on aftermarket KTM sprockets. On the motors I had, the sprocket width was responsible for setting the crush on the inner O-ring, and if the sprocket was too thin you'd have a C/S leak. HAD TO have the correct width in order to avoid the leak.

You won't have the same leak problem with the Husky, since the O-ring is not crushed by sprocket width, but I sure don't like the idea of the sprocket being able to move. I don't honestly "know" that it could knock the circlip off, but that would worry me. It would be an expensive catastrophe if it happened at speed, and potentially dangerous.

What brand was the sprocket? I'd certainly let the manufacturer know. And if it were me, one way or another, I'd get a wider sprocket.

JT sprocket. Checked w/ the dealer today about it. He sez it's normal, and has been selling them that way for 30+ years. It's no problem. Good enough for me...
