TE449 Front Sprocket loose

Performing some post-ride servicing and having removed the chain the front sprocket has some noticeable play - is that normal?

I changed the drivetrain about 200 miles ago (front and rear sprockets plus chain) so everythign is pretty new. Front sprocket is a steel Renthal and both sprockets are in good condition, no significant wear/hooking.

The 2 bolts holding the lock-washer to the sprocket are tight. The fitment is such that the sprocket slides on the shaft and the lock ring is slid on afterwards and rotated within the groove so that the "teeth" on the lock washer are misaligned with the splines to prevent it coming off, but that means that the only tension that can be applied to the sprocket will come from just those little teeth I can't tighten anything up to remove the looseness, all I could do is shim out the lock washer (or behind the sprocket) so that a little more pressure is applied when the 2 bolts are tightened.

Is that looseness normal, or something I should worry about?

Axial play: okay. Radial play: no good. (axial is side-to-side, radial would be fore-and-aft). from your description, it sounds good. I actually prefer that method of retention (or a giant e-clip which you could use too) as it allows the sprocket to float slightly.

Haha I've bn to the same technical school as u noobee.
