rebuilding ohlins single shock query

I'm looking to rebuild a single shock from a WR400. Is the dust cap a push fit like the twin shocks?
It has indents so I assumed it was threaded,I have it turning but its not unscrewing..
Any tricks to getting it out before I get medieval on it?
Any other tips gratefully taken on

thanks in advance

Pictures will help, your on about the resivour bottom bladder.
On mine is screwed into the bottom but that shouldn't need to be replaced the thing is held into the resivour by a c clip.
Push the cap in and pry out the clip then pull the chock out.

Its a protector for the seal head.. I have unscrewed it now. the seal was head was spinning. heat loosened all.

next question:
I have 2 shocks, I believe one may be 85 and one 86 going by the bottom eye length relative to the rebound adjuster . I believe the 85 has a long "eye" section and the 86 a short eye section.
The rebound adjuster being further away from the eye on the 85 and vice versa on the 86.
Any comments on the better shock to use from those in the know??

Hello
Where is a good place to find the rebuild kits, i have a 85' 250 WRX
thanks

try Phillip at husqvarna -parts .com

Will do, appreciate the info.

Call Ohlins directly at 800-336-9029. I have purchased many vintage Ohlins shock parts and kits from them.

As above. They have most parts for both the single and dual shocks.

no experience with these shox but have heard people say the later ones were better. check the linkage as they are different?

It is all bog standard Ohlins stuff - any modern Ohlins dealer / service agent should be capable of servicing them....

I think the length difference is wr, te, and ae for the short ones and cr, xc and whatever the four stroke long travel letters are for the longer ones. The linkage for 87-88 does not have a hemi joint at the shock bottom. The bumper on the shock rod can be broken and then missing if still original. There are a lot of needle bearings and races in those 85-86 linkages that were more problematic than sending the shock out. Not sure how things are on those bearings and races at this point in time. The Cagiva replacement parts were different than the originals.
