I want to remove the swingarm from my Navigator. I was hoping it would be a simple job, its looking increasingly like its going to get quite involved!
Any hints and tips please.

Arm removal
Peter, the spindle came out easily, it had been lubricated on assembly by whoever built the bike. no problem there.
That is as far with removal as I have got. Carrying on with the job later today.
After removing the spindle I hoped the arm would move about, enough to wriggle it out of the frame. Doesn't look like that's going to happen! Arm still firmly located between rear frame member and the frame tubes.
Do I need to slacken any bolts to create clearance?
Looks like the rear mudguard will need to be moved out the way, hoping not to do that.
Anything else I need to do to facilitate the job?

It should be simple enough…
It should be simple enough to loosen the frame bolts to release the swinging arm, I've not taken one out with the bike built up, but you should be able to see an exit route! Why are you removing it?! I have replaced a frame side without stripping the bike, i think i lay it on its side!

Loosen frame bolts
As Dan says, loosening the frame through bolts allows the frame sides to move outwards, giving more room for the swinging arm to come out.
Footrest bar and centre stand spindle backed off a few threads each side should do it.
Not many fasteners to remove rear mudguard assembly and chainguard. From memory s/a wriggles out at 45 degrees backwards/downwards.
CAUTION
The stops for the centre stand are on the frame sides. If your bike is on the centre stand and you move the frame sides outwards, the stand will collapse without warning.

Update
Loosened the frame bolts a couple of turns each side, watching the stand stops carefully. Also removed all the mudguard fixings. Hoping not to need to do that because the electrical bits and wring attached to the mudguard. Fortunately I could move the mudguard enough to some space to help with getting the arm out.
Another arm went in fairly easily. At that point the I started to feel the cold so have called it a day.
I'll finish the job in a couple of days when its a bit warmer.

We'll done, its certainly…
We'll done, its certainly chilly in the garage at the moment! I feel the need for a wood burner in there!

John,
Can we assume the swinging arm spindle appears stuck?
Probably corrosion between spindle and a silentbloc bush inner, or between spindle and frame centre bush.
Have you tried taking the nut off one end of the bush and tightening the opposite nut to try breaking the grip? Much better than battering away with a hammer.
In a similar situation at the frame front top studs, I seemed to get nowhere. But, by changing the nut used, to continually
reverse the pull direction, eventually movement started. Continued reversal of the pull direction. And application of oil, got it free. I had to make some spacers too when the threaded ends were clear of the frame.
