I am curious if anyone has a 3180c rod they could measure the crank journal and length of the rod. Trying to dtermine if it will for sure fit my HH60 engine. I am getting all kinds of different information on this rod.

May call around see if someone has one in stock to check....Call  "Jacks small engine" thier customer support has been real good with me..

The rod is a 31380C not 3180C.

There is a Tecumseh engine group and I asked them about this rod.  Below is the reply.  Given the part number change and no cross the chances are pretty slim of a match.

Response:

I don't have any spec's on the rods. The only thing I know is that in the suppression list they don't go back to a common part number so something is different. Sorry I can't be of more help but I just don't have that kind of information.

The piston's are the same, the stroke is the same, the diameter of the crank pin is the same so maybe the width of the rod is different at the crank pin????? I don't know.
