Does anybody know if there are any engineering drawings with dimensions or manuals available for the Sakae 12 and Sakae 21 engines?

TIA,

Mac
 
The diameter is 1150 mm. The 12 weighs 530 kg dry and the 21 weighs 590 kg dry. The bore is 130mm and stroke 150 mm. That's all I can find at the moment as I'm busy this time of year, but try this link and I'll bet something of interest is in the book. It's to a pdf I have The Nakajima Aircraft Engines book.

Thanks for taking the time to help me out, Max. I appreciate it. Are the dimensions you quoted for the 12 or 21?
