The fan belt from Gates, that I thought would fit, turned out to be too short. I have a new one coming that is two inches longer. It should give me enough room to adjust as needed.
I pulled the starter to investigate why the car was getting increasingly harder to start. About 50% of the time the starter would click once and nothing would happen. Pulling the cover off and using a tool to slightly spin the armature would allow it to start the next try.
I found that the commutator had two areas with significant burns and pitting. I replaced the brushes I could access (two of them require soldering on the field coils....not likely to happen), and then polished the commutator the best I could.
Speaking to a friend who helped with the engine rebuild, he recommends rebuilding the started completely. Apparently the burns are indications of brush hop, and will likely get worse. Possibly the armature is out of round and/or the bushings need to be replaced. I'll be heading to his place next weekend to tackle it.
Where do I find bushings for this thing?
