Step 11: Install piston to connecting rod
This is one of those places in the service manual where it tells you about identifying marks, but doesn't give you any clue what these identifying marks look like. From said manual:
Quote:

Orient piston and connecting rod so that the notch (Style "C" piston) or Fly symbol (style "D" piston) on piston and the match mark on connecting rod are facing the same direction.

I have a Style C piston, so the notch is obvious. But now I'm looking for the "match mark" on the connecting rod... Let's see:
You tell me which side has a match mark (?)
Fortunately, I was able to figure it out using the info from Step 12, which I knew was
very important on these Kohler rebuilds. The oil hole must be toward the camshaft. Here's the oil hole we're talking about
:
So when you examine the rod and its end cap closely, you'll see that there is only one way they go together correctly. I had to really look closely, and switch the end cap back and forth to verify several times, but I was able to see it. You need to assure that the outer edges of the castings match up.
So by getting this right, and by putting my oil hole toward the camshaft, I figure that the rod was in the right direction by default.
Sanity check!
I'm assuming, of course, that by saying:

make sure the match marks are aligned and the oil hole is towards [sic] the camshaft

they mean that the oil hole is toward the camshaft
gear. I mean, the camshaft runs all the way across. I know I'm nitpicking here, <edit 10/9/11> I was confused here, disregard...</edit> but dang it, this is important and I hate when things are ambiguous. Especially when I can't see which side has "identifying marks" on the connecting rod.
So I put the hole on the side facing the camshaft gear.
Installing it to the piston was simple. Just lube up the wrist pin with oil, put it through, and snap in the two clips to hold it in place.
