I have a Clemente billet rod…received in a trade….i have used a clement rod before on a hm80….this one seems different….its supposedly for a h50….the diameter is very close to the rod journal on the h50….the issue is, the thickness of the rod….it will not fit into the journal area….it is .903 something….the journal area is .887 something….on a h50/60 crank and a 70 is very similar….no markings on the rod other than Clement’s….any thoughts, been twisting and turning on this all week…what am I missing? Thanks! IMG_6674.png

Completely unrelated, but on a predator 224 I built a few months back it was necessary to grind clearance to the back of the block as well as the bottom of the cylinder sleeve on the front side to install an ARC billet rod. If I am reading your post correctly, it looks like you are off by .016". That plus .030" for safety should be doable.

Just re-read your post. Rod is too thick to fit between the counter weights. Is there enough meat around bolt areas to have .010" milled of either side?
It's that or grind on the crank to widen it a bit.

Well an update….i turned over the rod bearings and they had a number….this rod is a Clement’s. Rod for a Briggs flathead NOT a Tecumseh….so basically useless….

Not useless as there not being produced anymore. And never will be produced again. I have a billet clements head and flywheel i’ll never get rid of. I’m looking for a clements billet sidecover and billet valve cover. The rod is super cool.. i‘d wall hanger it.

To be honest I practiced today drilling a billet Alcoa rod to see how hard….im thinking of making a Clements shifter knob for me C model Powell….the Alcoa work very well….

I’ll get the direct part number off the clevite micros and let you know. arc bearings swap directly in place of the clevite micros and that rod looks good. Honestly it could probably be used in an engine. Probably stronger then the H-beams horstmans it looks brutishly beefy.

Well upon further review….i found an article from our friend Eric who, at the time, was in communication with Mr. Clements who stated in part that it is his rod and that the crank does need milled out to fit this rod….it is an h50 rod that I’ll need to do a search on to get the correct rod bearings….thanks for all the input!

he also made the Tecumseh billet rod that reads Tecumseh on them…
