Dust cap removal Dura-Ace EX

[lanab]

I am going to grease my bearing but don't know how to remove the plastic dust cap on my Dura Ace EX hub, the FH-7260

Should it be removed first of all?

It seems to have a thread inside for some sort of tool and a small pin hole at the outside but can't find any tool either for this.

Anyone here done it before? i don't want to force and breaking it.

I have a picture of it

Question - Does it need it? Looks to be a sealed bearing affair.

May I suggest the holes could be grease ports as with the XT hubs :?:

I wouldn't remove it. I have serviced hubs many times without removing it. I think removing it and having to place it back correctly should be avoided if possible.

I decided not to remove it as i could clean it anyway with my small fingers and put new balls inside and grease, all well.
