Title: Magdyno bearing
Post by: Ron B on 29.06. 2012 00:43

What is the difference between a E15 and a E15B points end bearing.  I can not find any size info on a E15B.  E15B seems to have a bigger ID than a E15.  Any bearing people out there?  Ron B.

There are three types of bearings used on the vast majority of Lucas magnetos, E15, E18, and N3048. Their sizes are 15x35x8, 18x40x9, 15x37x8 respectively. These are all available from my stock. I've never heard of E15B.
