Hello,
I'm afraid my clutch will die soon. It's a V06/630 Visa engine --> prae 1982 3 finger clutch expected.
Which brand/model/type of 2CV/Visa clutch do you recomend to transmit torque in a torque (and slightly power) tuned engine for a longer time?
Thanks

Hi Horst,
I don't know which make is the best/strongest. I'm not sure but think I have heard that 3 finger type is slightly stonger than a diafragma type.
Racers just use normal diafragma type clutches, their flighwheel are lighter and probably easier to lighten. Moreover they mostly deal with power rather then torque and just need a clutch which last for 24 hours... At the end of the day I never heard of racers having problems with the clutch...
I'd say, just get a decent make diagframa clutch and it will last the next 50 to 100 thousand if you are not driving like mad.
Good luck, Bart _________________ I like to play |

visa engine means compatible with GS type flywheel or am I wrong ?
they have bigger diameter diaphragm clutch (so does AMI Super) maybe there's an idea there ? _________________ "That bumper fits there like sunglasses on pig" O.E.

Hello Bart and JoZeF,
thanks for your replies!
The clutch seem to be 'recovered' (don't ask me why).
If I hit the gas pedal just at higher revs the clutch can withstand, maybe even at lower revs and WOT but I have avoided this during the last weeks.
I don't drive mad so I decide (90%) to get a old style hybrid diaphragma clutch - which I can purchase locally too.
@GS flywheel (10%):
What I could find out: the GS flywheel screw pattern should be the same, but it reaches more into 2CV bell housing than 2CV. This would be no problem since I use Visa/LNA bell housing.
But I like the 10deg (+45deg) BTDC mark of the OEM Visa inductive sensor pickups. Hmmm I could make simple marks on the flywheel...
What's about the starter?
GS starter is fixed on the opposite site, will this work? I'd like to keep a common 2CV starter.

Hi Horst, the GS flywheel will fit the Visa engine and the clutch is bigger but you say you have Visa/LNA bell housing, if you also have a Visa/LNA 'gearbox input shaft' it has different splines to a GS 'gearbox input shaft' so will not work with a GS clutch I think. _________________ More is always more |

Hello Joolz,
thank you very much for the hint with the input shaft!
I will not look (and pay) for a rare Ami Super bell housing so I can give up the GS clutch + flywheel idea...
Maybe I can fit a short GSA 5speed box into the 2 cylinder frame (and Ami8 body) at the same time when I replace the clutch.
It was damned narrow to fit the LN gear box so I don't know how to fix the 5 speed box. Even when I shorten the back cap of the box as much as possible.
But that's another story...
First I have to find out the electric problem to get the Ami finished until world meeting...

maybe a 4spd GS box would be just as nice and half the trouble ? _________________ "That bumper fits there like sunglasses on pig" O.E.

Hello JuanNavarro,
thanks for the link. That's exactly what I've done (LN gear box + LNA/Visa bellhousing + GSA brakes). But my final goal would be to use a short GSA 5 speed box.
Hello JozeF,
The problem is the 1st gear under difficult conditions (heavy load, slightly offroad terrain...). Since I use a very long gear box (AX DIesel) in BX 14 Break I know the feeling of long gears. Under normal circumstances this 'strong' engine is able to pull without troubles.
The Visa isn't as strong as the BX engine :) so I'd prefer to have a 'short' 1st gear.
I've got a GSA 4 speed box to test the long gear ratio, but this would be just a test project.
The journey to worl meeting would be nice test for smooth cruising, but I have not enough time to do this before. Ami8 (+ my EFI mods) require/s more time than 2CV front.
