Robert, I almost have a twin of your picture
I have had a very good dose of spanner therapy this morning this was the result at lunchtime:
So that's the nosecone off. The bumper insert is crusty but solid and as you can see, the rad is out, the battery box is out, the air box and the LHM reservoir are all out...
We're cookin' on gas

In fact that's the next thing to look at to isolate and disconnect...
Spanner therapy is something you just can't beat

It really does me a power of good.
Chris570 was with me for company this morning whilst he used my facilities to replace the 'P' bushes, round bushes and lower swivels on his Activa wishbones and new hubs.
Any queries regarding replacing any of the above, just ask Chris, he's now a specialist...
