[FONT=Calibri]I have a problem with my charge mixer eccentric bottom bracket, I am having great difficulty turning it to adjust the chain, my question is, is it possible to remove it and grease it so chain adjustment is easier[/FONT]

Did you have any luck with this? I've got a similar problem...

EBB are pain to maintain; I'd suggest even if thats not the root of the problem; remove, clean, degrease and regrease anyway. Park tools do a dedicated tool for this.

Dedicated tool? Looks like a pin spanner to me.

You can put something - say a metal rod - in one of the pin spanner holes then turn the cranks until the arm contacts the rod. You can then use the magic of leverage to apply a bit of welly to the EBB with the crank arm. Or scuff up the crank arm / break the metal rod if things really are a mess.

I have a pin spanner with a friend, but haven't been able to have a go at the EBB with it yet. Was wondering if it's possible to remove the EBB assembly entirely from the frame and clean/regrease it. Anyone had a go at that?

Never had to do it with mine. Would suggest removing the fixing bolts and getting liberal with GT40 through the holes.

That was my thought. When I get my pin spanner back I'll give it a whirl and post back some results/pics.

EBB are a piece of piss to maintain;

FTFY

is it possible to remove it and grease it

Yes.

1.Remove cranks

1. Loosen bolts that hold the EBB in place (under the bb shell).
   
2. Slide EBB insert out to the side.
   
3. Clean/grease/refit.
   
   

The bolts that hold the insert in place can chew up the insert. In this case it may be difficult to remove but a dunt from a mallet should get it out. SJS sell replacement Thorn inserts and Ithink they are mostly all the same size, ones that are held by bolts underneath anyway.
