RB-300 rebearing.

Post by awty » 28 Oct 2013 05:27

Hi all
Just a little note to those who might want to replace there bearings. I'm not going to go through the full process as most of it is self explanatory. Just a couple of points, that I'm not sure has been brought up before. I couldnt find any decent guide anyways.

This little inner nut on the vertical bearing does undo it just has a bit of locktight or similar preventing it from undoing past half a turn.
Think I'll leave it this way as I took out the little VTF spring ages ago and the rest is just a housing. Should make it easier to fine tune the bearing.

And there are a couple of screws under some plastic caps, that you should undo before you remove the arm post .....ooops.

The bearings came out with a gentle tap and the new bearings went in easy.
