Happy New Year Everyone!!

Okay, I split the engine and box today to replace what I thought was just the graphite thrust bearing. What I found at the bottom of the bellhousing was a little pile of graphite and 2 mangled springs!!! The thrust bearing had worn to the metal and had eaten the springs....out fell what can only be described as a steel ring with 3 lugs on the edges, making it look a bit like a triangle - I think this may the toggle?? anyway, it is what the graphite bears onto, it's still intact but all but 2 of the 3 springs that held it to the pressure plate exploded.

I cursed a bit but have been persuaded it's not a difficult job to replace.....however, I now cannot work out what sort of clutch I have in there. The pictures on "a well known parts suppliers" website don't look exactly like what's sat in front of me at the moment and my camera is bust so....here's the description

looks very similar to http://www.ecas2cvparts.co.uk/clutch-co ... -1227.html

but the difference is that each of the three spring-loaded 'tongues' have a little 5x10mm notch out of the end of their tip, and here sits the aforementioned triangular ring, held in place by springs in between each 'tongue' - you will notice in the link above those ones have similar springs holding the tongues themselves down???!!!!

the codes stamped into my mystery clutch are:

BREVETE SG DG
PKH 4/5 with 327 55 written under it
VERTO-BREVET in large letters, with PLANETE PKH written in the opposite direction over the top???? if that makes sense

also it has EMBRAYAGE (french for clutch) No. 4575 (in white ink)

A real puzzle for me, but probably not for some of you...

think of it as a New Years quiz question

NAME THAT CLUTCH (AND WHERE ON EARTH CAN I GET ONE)

Thanks alot
Will

AFAIK the clutch from ecas you linked to should be the one you need.
Think every parts supplier had their own shapes of the pressure plate.

If you want a lighter clutch, IIRC Club Cassis now has a diaphragm type clutch wich replaces the spring type clutch. . These engage and disengage with less force.

Hi Tom

Thanks for that - the bit that puzzles me the most is the 3 edged steel ring that the the graphite bears onto - what would hold that to the one on ECAS???

Cheers

Did a bit of a search, and found this on the site of Der Franzose:

Release ring clutch for 2CV 9-12-16 PS, AMI6, for all A-models with release clutch fork on top.

Never seen it before...

Der Franzose has got the graphite bearing and so:

Will,
after having a look at some of the continental supplier's websites for cross-reference, I think that this might be the clutch kit you need...

Unless you manage to find 'new old stock' of the graphite release bearing and pressure plate setup, fitting one of these replacements, which use a diaphragm type pressure plate and a more conventional release bearing, should give a lighter clutch pedal and improved reliability.

First thing you need to do is to count the number of splines on the driven plate to verify that it's a 10 spline kit which you require, otherwise I've started the New Year talking t&t@l b#ll*x.
Nothing like keeping up a tradition, is there?

Thanks Tom - yes, that is the piece!!! the bit i am calling triangular ring....

i see the franzose are selling the clutch i am talking about but when you click on it - it says old stock / out of stock...

i managed to get the graphite bearing from ECAS no problem...

do you reckon i have a clutch that was only used for a short period of time??? all the clutch kits with the graphite bearing included on ECAS are diaphram types....mine is coil-spring but with this weird triangle thing....

Will

Hi Ken

I think you got in there just before the penny dropped for me!!! thanks, i was starting to sweat a little - i think my pressure plate is old and uses this triangular bit as a sandwich filling between the graphite and the pressure plate - the fact that Roy only sells diaphram kits with graphite bearings was my epiphany moment.....i need to chat to him on tuesday

so do you reckon the graphite bears straight onto the 'fingers' of the diaphram??? or when you say more convential release bearing...is that still graphite - otherwise it won't fit into my fork. the little picture on ECAS looks like a graphite one? the one i think i have already???? or are you thinking of another one???

how common are these graphite thrust bearings - were they used for a long time?? on the 2CVs / Dyanes / or just Amis????

W

Will,
a graphite bearing can only be used with a pressure plate which has a smooth contact surface, such as the part that Tom identified, otherwise it will be destroyed in a very short time...

I haven't seen one of them 'in the metal' yet, but my guess is that these replacement clutch kits use a conventional type of release bearing, mounted in a carrier to suit the early clutch release fork.

ken

i am getting concerned that i may have a job finding the right clutch for my car - the ECAS clutch kit you suggested is 10 splines - my input shaft box is 18 splines????

i can't believe evryone with a pre-1968 gearbox has this trouble - cluthc is a service item after all???

W

Will,
rare perhaps, but not impossible to find...
