ID this Rod???

Post by Dan Hatch » Sun Sep 12, 2021 1:49 pm

C to C distance looks to be same as T, but pin diameter is 1.5 inches. Thanks Dan

If the big end is for a 1.5" journal, it looks like the rods that the late Bill Rader used in his A crank conversion engines. The rod was originally used in an air compressor. The problem with them was they are made from very soft mild steel - not a problem in the original application but …...

Thanks Dan. It is 1.5”.
So what you are saying is it is a wall hanger or in scrap pile? Thanks Dan.

Dan, I'd like to hang that rod on MY wall, if you're not already married to it. Thanks, Joe

I wasn't aware of those, nor ever seen one that I recall. But what Dan Mc E says sounds right. Just at a glance, the cap on that rod doesn't look adequate for a four stroke engine. An air compressor makes sense. The force on the rod is less extreme, and if a two stage compressor, the force may be always one direction (down/compression) because the first stage forces pre-compressed air into the second stage cylinder.

Probably for a stock motor that will not be abused they might be ok, but that's a choice the owner needs to make. I was never comfortable with them, as I found that it did not take much effort to open up the pin eye with a screw driver blade in the pin eye slot.

I have a set or 2. I was told they were air compressor rods to use a T piston in an A crank & possibly cheby conversion. They are not as wide as an A, as I recall. May not require the pan dimpling an A rod needs.
