An O-ring for the oil block, current replacement for older numbers 40-0202, 68-0597, 68-0598, and 70-8132.
This is a small O-ring used in the oil block area of the engine, part number 70-8259. The catalog record shows it as a factory replacement covering several older numbers - 40-0202, 68-0597, 68-0598, and 70-8132 - so if your parts book or an old bike lists any of those, this is the current equivalent to order.
