well you probably picked the hardes anim to find any info
i only know of the Nodding donkey or oil pump that uses it and in the first releases including the mlods , it wasnt working propperly, BIS fixed it in a Hotfix but unfortunately didnt release any info on why and how the fix was implemented.
i think these where the guts of the anims but again i think i discovered it was the p3d that was forked so couldnt get a fix .
axis = "osa_tyce2";
source = "time";
sourceAddress = loop;
its been so long i could not tell you if i got it to work though, it was frustrating as i was using it in an island like bis so 5 x the messing about.
