The bottom of the unit is the main bearing, with the rubber cover. There are three jubilee clips, a double and two singles. The top single clip has been loosened.
The circular unit on the side is the grease injection point. The 'bowl' is filled with grease and screwed on and the grease forced in.
Next up is the locking nut. You can then see the gland capping nut. Inside this goes the packing. The capping nut is screwed down to seal the whole unit. The following image, courtesy of the Sadler and Starlight Owners Association is an image of a similar unit.
This is generally known as the 'traditional' stern gland.
