Important, but there are only a few that I give a RIP about.

When I replace bearings in a 10 bearing reel, I generally replace 3 or 4 bearings. The spool bearings and the knob bearing are the only ones I care about.

One spool bearing is attached to the spool usually. If you can replace this...some you can some you cannot, the replace it. If not, don't worry about it

The bushing/bearing under the removable plate. Replace it. the bearing under the tension knob.replace it.

Here is a great provider for them: http://www.vxb.com/page/bearings/CTG...Fcqf7QodzC2uJA
