Hi,
I bought these a while back and was disappointed to receive them with an internal part blatantly rattling around inside. This must have been obvious to the seller and wasn't mentioned.
I've never worked on an old fork, but have done basic servicing when working as a bike mechanic and recently changed an air shaft when I stepped my lyrik down.
So without reading up, or finding exploded diagrams / service manuals, or anything, I decided to try and strip these down tonight.
I got this far:
It was the left leg that was rattling and the one you can see on the left side of that pic is the left side, (carelessly arranged next to the right side of the lowers -OCD destroyed
).
It's that lower part that extends down from the stanchion tube that's rattling around. You can see it's at a fair angle compared to the stanchion.
The same part on the right internal, has a small hole at the bottom, and all the black oil came out of there. So I assume only the right leg has damping. That was slightly rattly when I'd got the leg out, but not very.
This reminded me that when servicing more modern forks, I put a lot more oil in one side than the other... So obviously the same principles are still used 25 years on. What a great design!
For someone who's worked in the bike industry for 13 years, I've really never got into how suspension, mainly damping, works, so this is really interesting for me.
One of the sides was missing a circlip from the very top of the stanchion.
I don't have any c-clip spanners, so I'll be heading to Halfords first thing to get some. As I can't remove the rest of the internals to see what's going on with the rattly side, until the c-clips on the underside of the stanchions are removed.
I'm wondering if the spring has sheared...
I shall report back when I know more.
If anybody cares to offer any experience, please feel free!

The frame I've always had in mind for these isn't exactly mint either and I didn't want to respray that.
