You access the guts by removing the top cogs...but they wouldn't budge either. So i cut the top 2 off...then lifted off the bits and the remaining cogs. Then put the rest in a vice.
No. Its all there. It looks like there should be a locking ring, but the outer carrier with larger cogs just slips on locked by the top cogs. Silly design as you can't rescue the freewheel if you cant get the top cog off, unlike a more conventional design where you can pull it to bits and grip the guts in a vice.
This the freewheel with just the spindle pulled out..
