Steve i know this thread of Z2 Crank info has turned into anything but, ha. I Friend sent me a second Z2 "early" engine to restore. Meaning it will have the "Keyed" rotor crankshaft assy or part number 13031-044. Later ones weren't keyed, tapered friction fit and had a different part number 13031-1007. I know this thread is all of 11yrs old and still running but still interested in those fonts found on connecting rods?

The keyed rotors continued to the early 1000's. I have one.
I still have the crank so I can take pics of what you need.

As I understand it the key disappeared on the 1000 with the switch to the "big pin" crank and the later generator for the MKII around 1980 ?

Not sure if it was the first 1000's but I do know the went with a heavier crank for vibration. The lamb chops came back on the later engines,
I don't know why I couldn't reply to last comment on the quote.

BTW the fonts on the rods are 5ZZ on all four. They moved the pins to make it 58 not 66mm stroke.

I was just going to add some literature to your files when i pulled this Z2 engine apart. Haven't even pulled it from the shipping crate yet, waiting on S pring consistent weather. I don't need a crankshaft assy. Actually ran across a fella that had 1 complete engine and going to pick-up 2 more. Back to your tire changing Steve! Ya know there are service stations that do that..right, ha.
