Just curious, did you cut your sleeve down 6mm? If so, how did you do it - what tool would give you a really clean perfect cut?

 

At work We do the same to electric motors that we can no longer get. They'll last a few more years.....

 

A lathe. I want one but I can't justify it, for now.
The local high school has one and they enjoy new projects for the kids to learn on.

 

Can't remember if it was in 07 or 08... they went with cheaper bearings. Put new ones in... the stock ones will leave you on the road.

As for changing bearings for change sake... sometimes you get **** stuff from the MoCo... and it deserves/needs to be changed out.

 

Exactly what AKFXD said.. I have a buddy who is a machinist instructor for a local college. He has access to some super nifty equipment. He turned mine on a lathe and set a nice clean face back on the 'new' surface of the spacer.

 

Thanks, always good to have friends with expensive tools!

 

Related thread from a few months back, including photos comparing different bearings.

I have had rear bearing fail on my 86 FXR. 100% my fault for not checking them out. Was lucky that they screeched like hell rather than plain old seized up.

 

you all are over concerned with this stuff, a bearing is a bearing, they're all the same. they only fail prematurely when some fool damages them during install.

 

Hmm thats funny, I've seen many times bearings fail because of improper lubrication/ maintenance. They're not all the same, some have plastic cages VS metal, some have junk seals that dont keep out dust, dirt, and water thus letting in foreign that can and WILL damage the bearing surface thus creating play in the bearing and leading to failure. If you dont think bearings are something to be mindful of, please do not let passengers ride on your bike.
