Hi all thanks for the replies,

The only place I found any oil was in the free wheeling hub on that 1 side. The brake drum was bone dry. There wasn't loads, probably 100mls or so but just enough to wash the bearing. No idea how long its been in there either, but that's the side that has rotted a few springs on the hub that I need to replace.

I will google the swivel removal.

Thanks all

Adie
