ok then...
Had another go today. Soaked it first in WD40 penetrating fluid for 10 mins, no joy, soak again for another 10 min, bit of persuasion and it came apart.
Very happy. lubed it with moly grease inside and out. Did not have any of that white paste recommended on here so put a small smear of the moly grease on the gator instead.
Will use the right stuff in 12 months. Plan to do this at the beginning of winter every year.
Reason why I wanted to do it was the gator needed replacing and so this method makes it so much easier, also if any play or bearings start to wear in the final drive it just makes the job less expensive and easier for the home mechanic.

Feck me look at all the rusty water no wonder it was stuck together. isnt there a simple solution on the newer LC bikes that you can drill a small drain hole in the swing arm to release the water build up?
