Look at the oil holes in the middle of all of them.
Ya will find 2 holes larger than the other 2.
The large hole shafts are the intake shafts and the smaller are the exhaust. ...........lm

This spare motor was in a right mess - someone who did have a clue had had it to pieces before I bought it, and totally butchered it.
