Bearing movement with the sprocket carrier

Hi workshop,

I got an advisory on my MOT for the sprocket carrier bearing, so while it is thick with snow outside, I decided to have a look!

The actual bearing is fine, but can move slightly within the hub - what can I do? A drop of Loctite and press the bearing in or is that a bodge? New sprocket carrier?

Thanks,
Paul

could you take the carrier to a local machine shop and get the recess for the bearing machined up bya few mm and fit a bearing with a bigger outside size but same internal diameter ?

p.s. I would say that the loctite is a bodge and would likely not hold for long.

if there is movement it would be unwise to simply ingnore it, it will wear more rapidly than it should and will soon reach a point where the sprocket can twists sideways under load and possible cause the chain to depart company with the spocket, something that no one wishes especially at speed.

Get it sorted. I suggest you just fit a new bearing. The one in there is probably knackered or the wrong size.

The sprocket carrier bearing went on my GS. It did all sorts of damage, and left me stranded 40 miles away. I was lucky it didn't break the chain. But it did very nearly junk the swing arm as the wheel could twist and the bolts holding the sprocket onto the carrier hit the swing arm whilst spinning at 50mph etc.

My fix was to buy a new sprocket carrier. It was £20 inc postage and had a brand new bearing fitted.

Depends on the bike though.
