This may be the case in some instances, but their are exceptions. Part number 47-142-44 , a crankshaft, comes to mind. Kohler used this crank in a K321 and as a replacement for crank 47-142-23 in the M12. 47-142-23 was also used in a K301 once upon a time. So it could be assumed that one could use the 47-142-44 as a replacement for some K301 engines. AS far as crank and rod being considerably lighter, better get a scale and check what you have. I found in my case that by swapping from bolts to studs and nuts my K321 piston and rod weighed a few grams LESS then an M12 (which is supposed to be the same as a K301 internally) rod and piston. In my quest to rebuild my K321 I have found that not all is black and white with these Kolhers.
