Title: K2F magneto rebuild
Post by: Marqs1979 on 16.01. 2014 21:10
I'll switch to new bearings in my K2F magneto. Should I grease the bearings?

Have fun removing the old ones without the tool!

Yes the bearings do have to be greased witha high temperature grease.

It is a bit more complex than just "fitting new bearings", they have to be adjusted for end float using shims that go behind the inner race plus the outer races have fibre insulaters under them that come in a variety of thicknesses.

I would suggest you send your magneto to someone for a complete overhaul, get it done properly and you wont have to worry about it for many years.

I think it's fun to screw and try to do everything myself. Getting loose bearing races was taken by that hard :) This page is awesome :) http://www.brightsparkmagnetos.com/condensectomy/reassembling_magneto.htm (http://www.brightsparkmagnetos.com/condensectomy/reassembling_magneto.htm)
