thanks in advance

different......

From another website:
To identify the 10, 12, 14 and 16hp Kohler crankshafts, the 10hp cranks have a shorter stroke than the other cranks. You can compare a 10hp crank to a 12, 14 or 16hp crank by placing them side by side, and with the counter weights down, looking at the bottom part of the rod journal, the journal on the 10hp will be closer to the main journals. (3/8" of difference in stroke.)

thanks for the info, I have I have a 12 hp motor that needs redone and I have two 10 hp motors that I don't know what shape they are in, I guess I will have the crank redone and get a new rod.

No need to pull info from "another site". You have all you need here.

All this info is in the Kohler K series service manual. You can download it here if you don't have a copy. :beerchug:
