If I remember correctly you should remove the fan case Item 43. Then using snap ring pliers go through the slot in the clutch drum to remove the snap from its groove. Then remove the drum and bearing. Usually these bearings are stuck so removing the small snap ring wouldn't help until you the drum and bearing out then you can separate the bearing from the drum.

Just think of this like some puzzle. The large snap ring will be captive between the bearing and drum.
