Here are some pics of the sprocket and brake with the axle bearing. I have the following questions:
1. Can I use chemical spray rust remover from Home Depot to get the rust off the sprocket and drum and call it good? Or do i need to replace them? Seems like after using the chemical rust remover I can lightly sand the surface where it contacts the band and its good to go.
2. The axle seems to run pretty decent, should I replace the bearings anyway? I have no idea how to replace them.
3. The brake drum is 4" in diameter, so any 4" brake band will work, right? I am thinking this one
