Can you tell a 24v from an engine number?

As the concise title asks: are you able to identify whether an sd33 is 24v by the engine number?

.......from under the great down under.

I would not think so, its the starter motor and injector pump solenoid, and maybe the glowplugs that are voltage sensitive, the rest is just metal.
