Hold your horses!
Step one, undo little lock screw:
Which lets you unscrew the wiper cap with a pin wrench:
Then you need to push the billet alloy main seal/shaft support down to expose the snap ring it holds against:
Prise that out with a tiny screwdriver and you can remove the shaft support and the 3 captive seals:
This is the bleed hole to purge air from the shock when rebuilding in case you were wondering.
Progressive rebound bumpstop, to prevent that horrible 'click' you often get with GAZ/Avo/Koni's at full extension:
And the main valving piston, complete with shims and high-speed circuit backstop so that you can go jumping over humpback bridges if you like.
The patina is the oil draining off in ripples, not muck
PTFE coated PEEK main piston band, stagger cut for less leakage, and main body circlip:
Main compression stack shims once the piston is taken apart:
Compression valving side of the piston:
Rebound side:
The original rebound shims stack:
My rebound stack:
Remote res. end cap - secured with a circlip the same as the main seal:
And the billet floating piston:
There a barrel adjuster and another set of valving behind that, but I was just playing with a slightly tweaked valve setup.
They're got to come apart again for a little machining, and a modified Penske piston fitting with a 2* dish on the face (Fox pistons only have 0.5*), so I might get some pictures of the barrel adjuster and the secondary base valving if I remember.
