George, tight, then a bit more to put the split pin in.
Hope this helps.

Allen, Ha your awright Mate.
FYI the original wrench for this is about 20" long, so you might determine what "tight" was for a wrench like that being wielded by a 160 lb man in 192? who was in a hurry.
Then as Allan said: "a bit more to put the split pin in"
