When and if you do manage to loosen the lock rings, take care to do so over a bowl or towel which will catch the loose ball bearings. There was a good reason why this design never caught on at Suntour and was never copied by any other freewheel manufacturer.
Best of luck and let us know how you do.
I've dismantled and successfully overhauled several Winner and New Winner freewheels, with no specialized tools ( if you don't count universal spanner wrenches). A labour of love for sure. Judicious use of heat is your friend for getting them apart in the first place.
I like that as the attending mechanic, you have full control over the bearing preload, without resorting to unobtanium shims.

I can never remember. Drives me crazy.
