Bad news on my K321 crank
It will take at least .030 to clean it up. I may have stumbled upon another option today though. I brought home a retired K301 from an air compressor. After stripping it down, I have found a mint crank although the PTO end is the wrong size. Not a problem as I do not plan on using a PTO on this tractor. I also noticed the counter weights do not have flats milled in them, look just like the K321 crank weights. I then took the pistons and rods to the scale to compare the 301/321 weights. The 321 piston with rod and rings weighed a whopping 1/2 ounce more than the 301 assy. A whole 14 grams. I could probably lose that much in getting rid of the casting flash and polishing the beams of the new rod and piston.
I know the purists here will not like my plan but would you run this crank in a K321?? This tractor is gonna be for plowing and pulling a small trailer. The mower deck is staying on my 1200.
I also scored a good stator, a rectifier (haven't tested it yet), head, and cam shaft.
The cam has me wondering. This K301 had a magneto. No points. This cam was never machined with a cam lobe though the extra meat is there to do so. If I send this cam out to be modified into a "cheater" profile, can they grind the lobe for the points operating shaft?? Who can do this??
