Sachs Huret Deralieur Assembly

Hi there,

I'm restoring an old 86' Raleigh which came with some Sacs Huret Deralieurs.

Problem is, I'm pretty new to the whole restoration scene and after removing the deralieurs from the bike (for painting etc) I've forgotten how to reassemble them!!! What a newbie you must be thinking! But yes, in hindsight I should have taken pics of all the parts as i removed them....

Searching the web has turned up nothing [assembly guidelines etc] but maybe someone with one of these mechs or anyone with good advice would be very welcome.
Bearing in mind I'd preferably not have to visit a bike shop to have it re-fitted.

The rear mech is this one:

Cheers,
Ross

Ross,

Welcome to C&V and to old bicycles. We can be really helpful, but sometimes we need more specific information and pictures of your bicycle/parts are very helpful.

Are you talking about putting the pieces of the derailleurs back together (did you take them apart for cleaning)?

-or-

Do you need to know how to attach the derailleurs to the bicycle frame?

These are two different issues (both of which you mention, i.e. "reassemble them" and "have it refitted") and it would be helpful to know which you need help with.

Thanks for being more specific.

What type of Sachs Huret? I've got a "Rival" RD, but never disassembled it. I might be disassembling it (for further cleaning) for a project.

update - pics and info

Thanks for your replies. I really appreciate your help + iíve spent so long on this bike I cant wait to get it all back together and ride the hell out of it!!!

The problem I have is refitting the mechs to the frame - both DRís are fully assembled.
The RD is the Sachs Huret Eco S model.
I have taken pics of all the nuts, bolts and washers in the hope that you mighht know how it all goes back together...

Iíve numbered all the parts for reference purposes.




I have no Idea the purpose of parts 10 & 11!!! oops.






I also have a question about the rear mech and how to fit the cage/pulleys:

There are two options for the cage pivot point (as seen below).




Which one do I use?
Does this have something to do with cage spring stiffness?
Also, how do you decide which hole to use for the cage spring?


Thanks again. Looking forward to your reply

I have the same der.
Part #10 looks like the cable clamp washer (for lack of a better term), it goes on the cable clamp bolt.
The toothed washer looks like a previous owner add-on for some reason.

The jockey pivot points (#5) you refer to depend on the size of your largest sprocket. They should be marked on the side 24 teeth and 28 teeth. In your pic, the 24 is on the left, 28 on the right.

#4, Cage spring end - in your pic - depending on which pivot point you're using (each one has 2 options) the hole to the left results in less tension, on the right, more.
Same goes for #3 - cage spring catch - the left/lower catch has less tension, the right/upper more tension.

Set the pivot based on your largest sprocket size and try the less tensioned spring end and catch position first. I've only ever used mine in those positions and it has always worked surprisingly well.

It's a bit of a pain to get the right degree of tightness when you screw in the cage pivot bolt and attach the nut on the other side. Like they say - tighten until all play is eliminated and the cage swings freely without binding - easier said than done.

This might help with the rest of the parts - https://www.velo-pages.com/main.php?g2_itemId=2769

Good luck

Hi Malcolm,

Thanks for your post.

Would it be possible for you to post some pics of the derailleur on your bike please. That would be a massive help.

Cheers,
Ross
