C15a front hub bearing

[Bob Carriere]

Less than 0.488 mm difference........ how did they fit when you installed them?

Is the difference significant enough to feel the play......? or cause installation problems???

I haven’t installed then yet.

I’m curious with the serial number change where that coincides with production. I wonder if there was an issue that showed up.

[Bob Carriere]

why would they make such a small change???

I think either bearing would work fine....... we have parts that are worn out more than that and still acceptable.

Hanno is in the bearing business may be he can shed some light of why such a minor change.


Good Luck

Jordan, this is not so much my area of expertise, so, this might be wrong.
On page 5 of the parts book, 1125 is the number for the hub and drum.
I assume there is what is called a 5 inch hub (not identified as such in the listing) and a 6 inch hub. Each uses a different bearing. It is not quite that simple though as the 5 inch hub is also used with the 6 inch Rzeppa joint.
If you look in the back of the book it tells you all the pages that the base number crops up eg. 1216 crops up on pages 1,2,3,6,and 46.
Does that help?
