Nodrama - great post, very informative
Thank you.
Pozidrive - I think you are getting too hung up on the wording in the report. My diagrams are of a 139 TR setup which is near identical.
if you replace the word 'which' with the word 'and' then it might make it clearer.
Just trying to clarify an earlier post which said the control shaft
was the hydraulic piston. Also to understand why manual control isn't possible - in spite of a direct link from lever to spider via the control shaft.
