I have a set of pistons i need help identifying, this will take the expertise of a caterpillar expert. They are caterpillar pistons with casting number 8L 4066. I am told they were out of a 3304 engine but have not confirmed that. They only have 2 ring grooves, the top groove has a hardened seat for the compression ring and the bottom is for the oil ring.
