Right just had a better look and i think its probably ok the part i was worried about is actually the silver part in the centre of the top row in the photo , mine was stuck under the top cap also the lower race in mine fits much tighter in the cup than in the photo ? is the bearing in the right way round ?
The plot thickens
It's just a flat black plastic cover over the bearings on the lower race. My lower bearings are in the wrong way round. Has anyone's got stuck on top of them inside the lower race?
