blitz is right.
i checked the packaging of the C2 last night and they are indeed 4070s! now where do those brushes fall in relation to the whole spectrum of brushes available out there? - beats the hell outta me!
he he he would anyone know? blitz?
john: just rebuilt my C2 last night. its spankingly clean now, i degreased the factory grease out of the bearings and replaced with a dab of Tribo, cut the com, aligned the hoods so the wear mark on the brushes are smack down the middle - as usual the factory alignment was way off! they were wearing on the leading edge of the positive and the trailing edge of the negative brushes. i slapped on a new set of 4499s, broke them in @ 3v til fully seated, tore down the motor again and made a light skim cut on the comm then rebuilt it. unfortunately the only dyno i have is the track so i'll let you guys know how it turn out. these things always work for me though, especially the hood alignment, so there's sure to be an improvement.
