737 Classic CMD Seat repair

[bravolima553]

Hi all,

the back rest of this 737 classic CMD chair has a special mechanic. It seems that the power from the lever is transmitted over a oil filled hydraulic system, consists of two tubes and a branch to the transformers in the back rest. It´s leaking an I couldn´t get it tight. Does anybody have ideas, where I can get replacement parts for that? Can I convert this hydraulic mechanic into a ordinary one with bowden cable ? The seats are planned for a FTD not to be in service anymore.

On the photo below left you see the cylinder of the mechanic from the lever and on the others the tubes and the cylinder on the back rest
