[Gorgeous_Freeman]

can someone please post a step by step guide or a video to use the little sprocket tool and removal and replacement of the drive sprocket?

once the nut is off, I clean the threads on both the sprocket & tool well because the threads on tool are very soft and easy to cross-thread - next, I put a short 8mm bolt in the hole in the shaft where bucking bar was to keep the tool from mushrooming the end of shaft - most tools are 14mm for the push-bolt and either 21mm or 22mm for the tool body - hold tool from turning and tighten push bolt until sprocket pops off
