hello guys,

I'm starting putting together my car in the meanwhile other spare parts arrive.

I bought a clutch kit (valeo 826346) that supposedly was right for Fiat 600, Fiat Seicento, Panda 1980-2003.

Now, the clutch and the pressure plate seems right; but the clutch bearing is not: it is obviously too much different, and it seems there is no way that it can fit.

If you just can take a look at the picture, and tell me what do you think.

Incredible!!!!
I do have the C514.513 gearbox, but my engine is 187A1000
car version is 187AXC1A 02.

Also, my VIN number gives me on eper: 7662270 for a normal gearbox (there is also a special gearbox named 157, that I don't know what it is)

But using that code it gives me the wrong clutch bearing.....

So when Fiat put a car together, they slam in the first gearbox that come at hand.....
good to know!!!

At this point I can at least be sure that the clutch and pressure plate are right???
They seem identical, but.....
 
I doubt they just slam in the first gearbox that comes along. More likely they'll introduce changes to any components on a particular date and apply the new components from that date. The new components might be designed to solve a technical issue, fit a modified other component or just be easier or cheaper to build.

Then there are owners.... who over the 12 years of the car's usual life will change some components for any one that will fit (which may be the new component, the old one.. or something from a different model altogether).

If you order the Fiat part based on the chassis number you will get the part it originally had when it was new OR the latest replacement component (if the new one fits the car without any modifications).

Finally, sometimes the old part (or some related component) is not available any more, so you would receive the new part and then have to fit other parts to suit it.

I'd check that your clutch is the same as the old one. If it is, then you only need to change the release bearing for the proper item. Otherwise, you'll need the clutch kit to suit the existing format you have. Don't not replace the bearing. It'll fail and you'll need to do the whole job again. If you swap it now, it will not give you any more problems ever (bearing in mind the car's age/life expectancy).

No, no guys , I'm sure of it.
I bought the car as NEW, and I'm sure I never change the gearbox: I'm doing that now.

The only other explanation is that a mechanic swap my gearbox without saying anything and without charge anything.... but that's absurd.
 
wow you bought it new , congratulations you know it very well and what has been done to it over its life.
you can try and check the part numbers for the clutch friction plate and cover plate for both gearbox types, if they are the same you can be sure just release bearing different , which is highly likely.
good luck

Hello Ralf,

You are not the first 'poster' to ask this question(maybe regards gearbox's/thrust bearings yes?) but Fiat, as big as it is could have fitted any combination they had at the time. No business stops because of a 'minor' problem such as that through lack of supply/parts. They may have just thrown in a gearbox (albeit NOT the exact one) that they had to keep things moving? Who knows? Wouldn't be the first time. Built by robots.....You didn't notice until you had to change the clutch...? Think we would all be in the same boat as yourself.

Did my clutch last summer. 170,000 odd Kilometres... Had the lower bearing in your photo, not that I could recognise the old one...it was in about 30 pieces...

Take your old one(if you still have it?) to a Motir factir or Fiat deaker, the microphee....microphee....computer should have an exploded diagram on it to show the part you have? Then again.......

In the meantime I've ordered a SKF release bearing.
Looking on the Saschs website, I found this:

Clutch disc: 1878 050 741
Transm. Type : C514
Parameter: 180TP
Diameter [mm]: 180
Hub Profile: 15,1x17,3-20N
Number of Teeth: 20

Clutch disc: 1878 600 843
Transm. Type : C526
Parameter: 180TP
Diameter [mm]: 180
Hub Profile: 15x17-20N
Number of Teeth: 20

The hub has 20 splines in both cases, and the diameter is 15 mm from top of the spline to top of the spline; and 17mm from bottom to bottom; I don't really "feel" the 0.1 mm or the 0.3mm of difference: my caliper doesn't "wiggles" inside the hole in a different manner, and the two clutch discs fits in the exact same way on the gearbox axle.

As someone suggested, I also checked the OEM code and they are different:
46780580 for the C514
73501468 for the C526 (called opt. 157 or simply 157).
:bang::bang:

But, I repeat, I don't see any difference, and pressure plate and clutch disc fit perfectly on the flywheel, too.

I have no idea because I don't know very when the sporting model has been started/ceased on the production line.

In eper a found a specific explanation that opt 157 or 157 is the C526, and, in theory,
production stops at the end of 2002.
