You sir are smitten the bike looks perfectly OK in the first two pics.

On the left side of the swing arm is a cotter bolt, the head is a 5mm allen and there is a nut on the other end. DO NOT try to rotate the bolt with an allen key. Remove the nut from the bottom and drift the bolt up and out, you should now be able to drift out the swing arm spindle (not sure if the DSS clamps on the right also), there may be shims if so make a note from where they came.
Once you get the swing arm off IMEDIATELY stuff a rag in each side of the case needle bearings. You do not want to know how hard it is to change these.
Have a look at the shaft for wear, about £35 for a new one.
