Looks like that is actually CAT??

3.500" or 3.480" stroke as a guess, based off part number.

It is a 3.48 stroke. I'm trying to figure out what metal it's made out of.

Guess you could smack the part with a wrench hung on a wire or supported by a small point. steel will go RINGGGGGGGGGgggggggg....... ductile iron will go DING.. cast iron will go THUD. ymmv..

Definitely rings. Have a cast scat crank here also, as well as some stock cranks to compare.

Scat contacted me back. Current pn is 435034805700 so it's a descent crank.
