Looking for help on how to remove the brush holders on a Polar Cub type G.   One brush was basically missing, the other is fine it seems.  But would really would like to remove the rotor so I can polish the commutator too.  So again are there any tips for backing out the brush holder (carefully) so that I can slide out the stator?  Thank you anyone who has ideas or experience.

Mark, I have never messed with carbon brushes - the one time I took one off an R&M 3600 I lost the spring & broke the brush!! Darryl had to make a new set for me.Good luck!

Does your Polar Cub have the tabs bent over on the back? Two on each side that keep the holders mounted.
Bend the tabs out carefully and the holders should wiggle out. :)

Thank you for the feedback Alex.   I had a hunch that was the trick but wanted to make sure

If one spring is shorter (see pic) - could that lead to uneven brush wear.  I swear only only one brush came out.
