I'm proudly restoring my grandfather's 1966 650. He passed a couple of years ago and this is the first of two I'm restoring. Stripped it down to bare metal in most places, primed and repainted and looking good. My problem is reassembling the clutch and PTO assemblies. The medium tubeframe manual is pretty vague and the parts catalogue exploded view is a little more helpful but doesn't really give good enough visuals for the relationship of some parts. Does anyone out there have any direction or advice? I had to rebuild the tranny after replaces wormshaft, wormwhell and pinion gears, that is working okay but it won't do me any good if I can't get the rest together! Have new decals ready to install as well so it's going to be a nice one when I git'r done.
