Who's replaced brushes on Bosch starter?
Posted: Sat Nov 09, 2013 12:36 pm
I've been asking around on this one and I'm getting mixed answers. Hopefully somebody that's actually done this on their airhead starter can help me out.
I decided to freshen up my starter - replace commutator bushings and replace brushes. No, I'm not messing with the Bendix bushes - they're ok anyway.
My objective is to do this once and not mess up so as to make the starter unreliable.
The original brushes were spot welded on both the brush plate and the armatures. I ground off the the old braided leads from the connection points. I was going to solder the new brushes on with 50/50 solder but some have told me the amperage can melt it off. Don't want that do we?
I don't have access to a spot welder. Silver solder was suggested but I worry about applying the amount of flame to the thin armature connection point. I guess silver solder would be easy for me to make connections at the brush plate for the commutator. Another option I guess would be to devise a crimp around the brush lead and the armature connection then try to solder that but again I worry about silver soldering the thin armature connection point.
What have others done????? No, I won't be going to an automotive starter rebuilder - I just want to do it myself and looking for the best method. I've received some advice from others but I don't think any of them have actually done this job before
thanks
