Correct. The pin is pushed in hand tight (in 1941 they had strong hands), and the slot is to rotate the pin to align the locking cotter pin. Perhaps an Air-powered rattle gun with a screwdriver bit to free it up while you apply heat? If you had the larger pins from a bigger CMP, you could thread a slide hammer into the grease nipple thread in the end. It would seem odd there is no access hole to drive out the pin with a punch.
