Rear spring setting

Hi all - and especially Huib!
I am rebuilding the rear suspension on my 200kmile 1600 Sport after 36years of neglect. Apart front the usual rusting up of bolts and shackle pins (which have now been cut off / retapped etc by me in preperation for a rebuild), I cannot remember where the information is to re set the rear springs on assembly back in the car.
I seem to recall this was discussed (Huib) previously a few years ago but cant see on any search of the forum.
I think the procedure is to assemble "loosely" and then do the shackles and front silent block up tight when the rear is normally loaded?
Is this correct or should additional load be applied - measure bump stop gap???
Any info please.
Tim

Well, I have found it both in the big manual (mostly series 1) and the series 2 consise manual.
In small print they both say that all linkages/silentblocks/antiroll bar bottom links should be locked to correct torsion settings when bump stop is 80mm from leaf spring top plate.
I knew it was somewhere....

PS failure to observe this will generally lead to a "jacked-up" car and possible damage to the silent blocks.

Right Tim. Let me repeat for the new comers that it is vitally important to fasten parts which are joined with silent blocs in the correct position. Silent blocs are hinges with very limited swing travel, typically 15 to 20 degrees either way. Exceeding this maximum swing angle will lead to destruction. Note that both the inner and outer bush have to be securely fastened to the corresponding part either by pressing it in or clamping it with a bolt. I sometimes get cars in my workshop where the bolts are loose and used as a spindle with the silent bloc turning around it. I can only guess that the person who did this assumed that the rubber is only for vibration damping. Bolts are never to be used as spindles. Bolts are to clamp two or more parts together.
The correct positions are in the workshop manuals as well as in the Technical Data Book. If the data can not be found, the center position between the swing extremes is a good guess.
For the rear spring it usually means that extra weight has to be put in the trunk. My suggestion of a few years ago to which you are referring was to put two women in the trunk. Since then the world has changed. Claire usually does the torqueing now and she put Lucas and myself in the trunk. She is a good girl. She bribes us with a bottle of Prosecco and some good cigars.

Lucas, someone has to eat the cigar

...
sorry for such cheap (cigars) humor, but I am happy today ... because the sun is shining & next week me & many other Gamma Nutz leave their desks... for 4 days... enroute to the Toffen Oldtimer Galerie near Bern, followed by a historical-location ( I am told) stop near Montreux (smoke on the water, a fire in the skie) , then up & over the Alps, in a long convoy of nordlander jelly-bean-color Gamma & then down the other side of the Montana, to the 'home' of all (remaining) Gamma...Torino
for 3 days of Italian culture, fine arts, delicate food, high-class friends, perhaps a visit to a few historical sights, a wineyard, and the best part is that I don't have to pretzelly myself, nor 2 passengers into a l
loud cigar-shaped Fulvy Z that smokes pipes !!
Actually, I will enjoy being a passenger** on this trip & let the other guys drive !!!
Details of the Mega Gamma Meeting can be seen on

I assume we get to 'drive on the roof' before we go to the Vinyards
The person singing is: Fulvia a.i.
"on the road again (join in) I just can't wait to get on the road again...."
** I can drink what I want (yipee) , when I want. With Phil & Ruud as Piloto, I am in good hands !!!

ha ha, I think a Mini-Van (or a maxi van) would be more likely; for my old bones too!
haha...last year Claire told me she was "recently" in a dark Coupe boot, with the lid down of course; with a flashlight in her hand, while she searched for the leak (s) that filled the boot; while Huib sprayed the car, with tons of water. She didn't drown and I can't remember if the leak was discovered.
Of course, Huib let her out. If he hadn't...she could not have told me about this 'tight-fit-experiance'.
She was not smoking a cigar !
Maybe she was in Rosa (her lovely Coupe); that I could understand !
