Drive Sproket play

Is it normal for the front drive sproket to have rotational play on the output drive shaft. I have about 5 degrees of movement.
2009 TXC-510

No, that is not good.

The 610's have a reputation for loose fitting sprockets that is fixed with a new aftermarket sprocket.

Eventually you will wear out the trans output shaft if oyu let it go too long.

Buy a new sprocket and see if it fits better.

All of my bikes seem to do that as well. Must be normal?

Alot of DRZ's had that problem and it would cause the sprocket to wear the splines off the shaft. I dont know if it was because the shaft was a little to soft or because of the freeplay, but some people would use loctite to tighten up the fit.

Hey,
I bought a T14 new sproket last night and installed it. Its the same movement.
I have filmed it and sent it to Husqvarna in Italy for a response.
We will see.
Thanks for your input.

To clairify; The DRZ issue wasn't one of wearing the splines off the shaft. They had a rare issue of C-shaft seizure related to the CS sprocket being able to move slightly on the shaft. Red loctite on the splines solved the issue. It didn't happen very often, but was potentially fatal when it did, as you were at the mercy of a suddenly locked rear wheel regardless of the speed/situation. There were a few really bad wipeouts from it.

This issue with loose CS sprockets on the 610 popped up on TT about ~2 years ago or so IIRC. I don't recall the sol'n.
On that 510, 5 degrees of play seems like a lot & will likely cause damage to the splines. It could be that you have an improperly machined C-shaft........
