If there aren't, and if he's got the cover off anyway, then if he can see, or feel with something, the pinion, he can just count the teeth on the pinion and the crownwheel, divide the latter by the former and get the ratio.
Easier just to turn the input flange and count the turns needed to get the outputs to turn one full revolution, though.
