Im gonna rebuild my starter next week, the brushes failed. John at JSS is hooking me up with:
New OEM brushplate
New OEM needle-bearing which comes with the dust seal
ALL new gaskets for the starter, including the o-ring on the front
The commutater and spindle and gear are all in great shape, so Im just surface cleaning the commutater, putting in the new brushes, bearings, and gonna coat the new gaskets (old one were dry rotted) with form-a gasket just as added security, then paint it all up.
I would worry about the dust seal for the needle-bearing, and John has the OEM ones, which come with the starter bearing rebuild kit.
All in all, to rebuild my brush plate and bearings and gaskets, I think its a little less then 100 bucks, and all the parts are OEM.
BTW, Matt, if you do decide to put in another needle bearing and dust seal, the bearing and dust seal are pretty hard to get out. I had to find a socket that would fit through the front cover hole, but catch the edge of the bearing, and then heat up the cover with a torch, and then tap the bearing out with a mallet, they really are pressed in there. I think I'm gonna have to drill out the brass bushing bearing in the rear cover, that ones pressed in pretty tight as well.
