FD bearing

[ChrisH Kerry]

I have a spare FD bearing and was just looking at it - there is distinct play between inner and outer races which seems wrong. It's still in the plastic wrapping but I can definitely feel and see the races move if I apply finger pressure to sides. Is it a candidate for return? Surely must be...

Yes.

 

[DrFarkoff]

Yes.

NO Depends on amount of movement

Remember it is a C3 clearance bearing and should have clearance when cold

 

[ChrisH Kerry]

Still not sure about this bearing
It has a bit of play if I hold it like this:

and press on centre bit. Maybe they are supposed to be like that but before using it, would be nice to know for sure. There's a very short video here (dunno how to embed Youtube vids....)

Cheers

Chris as long as it was supplied as a C3 clearance then that is fine

Yes they have a little bit of movement when cold

Hard to tell from the vid how much yours has?

Just been out and checked my genuine BMDub spare bearing.

Up and down play the same as yours

Same here (still in its BM wrapping).

Great thanks for replies - never come across that sort of movement in a bearing, but then haven't dealt with ones that size or application. Don't have to send it back anyway

It should be a good make bearing not a Chinese/Indian or no name one? if so don't use it.

Genuine BMW one - from what I've read on here it seems they're as cheap as any other source, that's why I was worried!
