locked spax shock absorber

[p7rider]

I've had Spax on my spitfire for probably 20 years and i've just removed the fronts for a suspension overhaul. The shocks still look like new , but I've removed the springs and one of the shocks has locked out in the fully extended position . Any ideas I have twiddled the adjusters before i noticed it was stuck. Hope someone can help .Thanks

I would worry it could happen again when fitted on the car. That would be exciting, and not in a good way.

 

I would fit Koni's (but that is me, and not the answer you are looking for)

One suggestion is that after twiddling the adjuster , is when I wound it out again somehow whatever restricts the flow has stayed in . A friend suggested this as it happens on his motorbike .

If I undo the outer ring around the adjuster can I remove it without disturbing oil or gas pressure seals ?

Had an email from Spax suggesting there had been a sticking issue in the past and they wanted serial numbers. suggesting I try harder to compress it .

Well I gave it to a friend of a friend who builds shocks and he got it working . basically as Spax suggested. He tried them on a dyno and said they are ok

and in good condition, having previously groaned when told they were Spax. Also suggests it was just sticktion and to put a bit of grease on the damper rod.

although I was told what type, but remember having some bike forks built and they put silicone grease under the seals. So hopefully all is well
