Help with Alfine 8 regrease

has anyone regreased their alfine 8 speed hub, I have got to the stage where i have taken off the sproket and a black rubber seal, all the guides tell me I should now be seeing a knotched, large dust cap which should twist off clockwise. I see it (part 12 in the service guide) but it is covered by the flange cap, (part 30) do I have to take off the flange cap, if so, how? Guide is here.

Thanks in advance!

This picture shows the stage I am at, with the black flange cap (lh pic) covering the edge of the grey dust cap.

answering my own question, both flange cap and dust cap pop off with gentle persuasion from a screwdriver. Now to clean, regrease and reassemble (gulp)

All seemed to go ok, including reassembly, however on first outing I am encountering some 'drag' issues (pedals turn when coasting). I am hoping this is down to a too tight chain/cone bearings rather than something that requires me to break it down again. Am a little concerned I may have used too thick an oil/grease, if so I am also hopeful this might resolve itself over a week or two. Any suggestions welcomed.

I had mine serviced a while back. Did not notice any drag or pedal turning issues afterwards. Can't offer anything more helpful I'm afraid.

Thanks.
I am using this thread to voice my thought process and in the hope that people might have helpful suggestions.

As I said I am very hopeful it is just that I have tightened the cones too much or that the chain line is off/too tight as it shifts really nicely. After ruling out these options I will try taking it apart and reassembling, perhaps after dunking in some oil, to move the viscosity balance of the oil/grease mix more towards the oil end of the spectrum.

I have to say the maintenance benefits to seem to be somewhat negated by the servicing process.

Not the cones/chain, looks like I will be finding another time window to strip it down and try and move the oil/grease balance in a less viscous direction.
