Hi everyone

i just collected a set of bearings to rebuild my gearbox with, but the ones with the circlip groove have a narrower groove in them than the old ones, they have also come with a full circlip rather than a half one, this means the bearing could move in housing does'nt it, where should i order my bearings from to get the right ones.

Hi Andy. It's been a while.

Can you post pics of your bikes?

Here's the Seeley at North Weald in 2006 (September I think).



Eamon did eventually buy a Seeley (from Stafford) but had to sell it recently due to straitened financial circumstances (too many bikes, no job)

I think the only place you can get the correct bearings is Honda

UKROBK7:
Where did you get them from?  I agree with Brian, I thought the Honda grooves were slightly different in width from the industrial standard.

the-chauffeur:

Yeah - the boys are right.  I had the same problem when I replaced all of the bottom end bearings with SKF's (don't ask how much).  The SKF outer groves are about 1/3rd the width of the ones from Honda.

Unfortunately, at least one of the Honda bearings is obsolete - I think it's one of the grooved ones - and I couldn't find anywhere that would supply the right groove sizes out of the box.  So, I took my new ones to a local machinist with the old bearings (together with the Honda circlip thingie) and got him to match them.  It's not that hard for someone with the right gear - I think I was charged
