912 Rear prop shaft seal replacement

[egp8111]

Folks,
Somehow I managed to pinch my oil seal when I was replacing my gearbox after an overhaul so now it leaks. Has anyone ever replace the seal ( the rear one on the crankcase)
I'm sure it must be in the heavy maintenance manual somewhere but darned if I can find it. errrrr
Thanks

well, the seal is shown in illustrated parts in gearbox section (item 29) and is mentioned in line manual 05-50-00 page three, 1.1, item 5 as "see heavy manual 72-00-00. However, not to be found there. Very strange????

this info comes from the 912iS manual which is similar to the 912 manual in this section.
