After drawing a blank on help with service of this Caille mech, I decided to give it a go myself.
Quite different to Mills and Jennings mechs and not as well engineered, in my opinion.
Very quirky, and has a noise all of its own, similar to Watlings and the like!
I noticed it has two design flaws:-
Firstly, this mech should have been redesigned, as it is basically the same as the 1920s centre pull mech (Victory Bell).
Note the push down bar at the front, a hangover from the centre handle.
It should have been reengineered to work with the side handle exclusively.
This mech is from a 1934 Dictator, the first machine brought out by Fuller-Johnson who bought the Caille brothers out in the early '30s.
They primirilary bought them out for their outboard motor boat engines division!
Secondly, the hydraulic clock!
These have a well founded reputation for making these mechanisms unreliable as well as an oily grimy mess!
I had to totally rebuild what is essentially a hydraulic door closer.
There are four seals and I had to replace all of them!
If you don't, the fluid just finds the weakest seal and oozes out on every pull of the handle.
The thing I find unbelievable is that Caille made such a big thing about the hydraulic clock being "as silent as the stars" in operation, which it is.
However, if you look at the video to see the way the kick-off is designed, those reel disks skimming the latch of the kicker make much more metallic chatter than a regualr clock and fan ever did!
It was rushed into production to compete with Mills who had brought out their much better engineered Silent Line a year earlier.
Totally defeats the point of having a silent regulator!
