Seized chain adjuster?

Came to adjust my chain last night on a SSSA ST 955. Thing has seized solid. Only had 10 mins to spare. Have 2 more 50 mile journeys to do on it before I can afford for it to be stripped down properly. Would really like to adjust it now if I can as its pretty loose.

Anyone ever done this? How much time should I allow? What are the chances of freeing it up with a hammer before stripping it?

Many thanks

Didn't really have time to put the hammer down before as it was running repairs and she's a working girl bless her.

Had the back wheel off for a new tyre today, which was an idea time to do the adjuster. For anyone else reading this and as a preventative measure, its actually the brake caliper mount which was seized in place and needed a few solid taps with a lump HAMMER to knock it off (I know, you must hate me).

Main thing is that this needs some sort of grease, otherwise you'll run into the same problems if you do any wet miles. Copper slip is the first thing that comes to mind, but I'm hoping someone on here has better ideas?

 

Thought I should just put a little clarification on this:

I had the wheel off as well as the sprocket and axle. After removing the circlip which holds brake mount on to the adjuster cylinder, then unbolted the singular allen bolt which keeps the brake mount from spinning round. At this point you should be able to rotate the whole adjuster cylinder round inside the singing arm, though the brake mount plate is solid.

Then it is just a case of repeatedly tapping the brake mount plate until it works it's way off, each time rotating the cylinder so that the thing come off squarely.

(The hammer and chisel method is purely for adjusting the chain when it's seized and you don't have the choice or the time to strip the thing down)
