Thanks Stu, so it is as someone mentioned, a left hand thread. So if I can get that to come off the whole thing should come apart. Its going to take some moving though, its been on there over 30 years by the looks of it.

ozone:
This is probably the correct tool for the job.  Won't be cheap though..

stevepeanut:
Big thanks to DiscoStu for finding that link.

I held a lighter on the locking ring for ages to get some heat into the ring, and it drifted out no problem.

This is whats left on the hub. I am pretty sure this last bit is pressed into the 5 star hub bit.



These are the parts that have came off when it came undone.



And this is what is playing up, two little tabs that must close when freewheeling and open up to lock the freewheel.




I can't see anything thats an obvious cause of failure, I am thinking possibly the little tabs are not opening out because they are caked in thick dirty grease.

I am going to reassemble it tomorrow, I will grease up the bearings tomorrow. Can anyone tell me what kind of grease or oil I should be using on the tabs?

HEYWOOD BMX:
 :) The 2 little tabs are called pawls.Use a very light oil and you should be fine.

GLAD YOU GOT IT APART. I ALWAYS STRIP, CLEAN, RE GREASE , REBUILD THIS STUFF EVEN IF ITS NEW (OFTEN THE WORSE ADJUSTMENTS AND CRAP STORAGE GREASE)
