I just finished adjusting clutch on a total restoration of a 1948 B, and everything works great. However, I seem to have have more noise than normal in the pulley-transmission when traveling (noise stops when pulley stops). Noise goes away when going downhill. I rebuilt bearings in the transmission, so suspect the pulley set-up. I replaced the crankshaft with a good used one, and put in a new pulley bushing, roller bearing, seal, and retainer. I'm not clear on how the pulley roller bearing is lubricated on a late (212,873) B, but the manual doesn't talk about packing the bearing so I assumed it was oiled somehow. Was I supposed to pack the bearing with grease? other suggestions?
