Got it steeping in degreaser, will leave it for a few days.Try working some 3in one oil down into the clutch and wiggling it back and forward. Sometimes it works.
I just wonder if the springs are rusted away? saying that I cant hear anything rattling when I shake it.As above a member on here did exactly that soaked his clutch in some degreaser or some such liquid to get his working worth a try.....
Topbikekit do their own make as there is not an AKM 250w cassette model that I can see.If the connector is a std nine pin Julet then yes. All of the AKM's use a two stage gear set so internal hub gearing won't be too dissimilar.
I would not use any water based degreaser as it may cause some rust.Got it steeping in degreaser, will leave it for a few days.
Thanks
