[Vwdiesel] Rebuilding 90w Alternator

[mark shepherd]

I cannot say about this particular alternator, but a trick I have done on 
several old but otherwise serviceable  alts, is to 'ovate' ? Ovalize? :~) 
the brushholder screw holes and pinch another mm of wear out of the brushes. 
This can give a few years of extra time before brush replacement... Does 
that make any sense?
