This KHK camshaft was heavily pitted on each end from corrosion. The cams ride in bushings on these motors, so a small amount of pitting is still usable. These were bad. I had McFarland machine down the pitted end, and make a new sleeve that pressed on, giving us a smooth surface again. We fixed 3 of the cams, made a complete shaft for one (since these shafts can be pressed out) - and now Kevin has a fresh set of cams (which are hard to find) for his '55KH.
