I got the the full D7 TB stripped down; except for the swing arm (rear fork) and front forks.

Swing Arm:  Its frozen and won't budge.  Id rather not break anything....so any tips on how to disassemble it?

Fork Caps spin with springs attached, and they are anchored into the fork legs.  How do I disassemble these?

I cannot answer for the forks but the swinging arm is a concern because of the way the rear fender stays were attached to the bottom shock absorber mountings would effectively render the bike a rigid frame.  Or bend the rear fender dramatically as the swinging arm tries to articulate.  I would advise to check to see if it has been welded up solid before you start to soak the whole thing in plus gas or diesel etc.  

If there is no sign of welding up then i would advise use a bit of heat first and it that doesn't work then soak it all in a shallow bath of diesel for a week or so and then try tapping the swinging arm up and down with a soft mallet to see if you can get it to articulate. 

There is no reason why the swinging arm should be siezed solid - I have had a few that were very stiff but with a bit of persuasion they usually yield. 

Once you have it moving you will need a press to get the pin out - thats another task.

The springs are secured with  a "screw" type arrangement at each end.At the bottom of the fork leg is a cone with the screw arrangement at one end and a threaded hole at the other which is held into the bottom of the fork leg with a small threaded rod.The bottom of the fork leg is threaded for the rod aswell20190605_232647.jpg

.An absolute pig to get out to be honest although I'm sure theres a way.

25,26,8 and 13 are the offending articles.
