Vectra C - Crankshaft Pulley Replacement: OEM Numbers, Vibration Damper - Are They Interchangeable?

Question

I have to replace the pulley on the crankshaft (the one with the vibration damper).
Disassembled from the car looks like this:

Meanwhile, searching by part number gives something like this:

The fastening screws visible in the photo are definitely shorter than those in mine.
According to OEM numbers, this should match. But I don't really see it after my appearance. Anyone know if these wheels are really interchangeable or do I need to buy identical?

If the wheel is thinner, the bolts are shorter.

MikeC · Answer

They are as interchangeable as possible (and of course you get other bolts in the set), buy wheels only from well-known (branded) manufacturers because you will have to replace the cheap ones in a moment.

The wheels are interchangeable.
See that the circle in the first picture has a thicker center - the width of the outer part on which the belt works.
The circle in the second picture has a smaller inner width, so the screws must be shorter.
Look for something branded as mentioned by a colleague above.

Last week my friend and I finished making heads in his JTD (two broken levers, valves OK). The new wheel, like the original, withstood 20kkm and fell apart, there was sludge inside, not vulcanized rubber (additional fun in cleaning).

Fear to be afraid ... sincerely wish you good luck and happiness.

Maybe it was mounted incorrectly? I recommend Corteco, no complaints

You can't be sure of anything in life although, unfortunately, there was no error here, only a problem with a fake. After buying another wheel (also RICAMBI ORIBINALI) you could see the differences.

It was badly produced, which contributed to the meager price, and someone got it right.

I have established that there are 3 versions of this wheel. The two types are interchangeable - one has been replaced with a newer version, while the third type is different but looks similar.
It is necessary to select VIN which will be the type.
I am attaching info from FEBI, it may be useful to someone:

Hello, not to write too much, I have exactly the same situation with pulleys, I bought both, I will return one of them. I have a different problem, I have to do it at home without an electric wrench [impact screwdriver], such as is used to unscrew the wheels, can I unscrew it with a normal socket wrench with extension??? And the main question, did you do it yourself and, for example; did you put your foot in gear and someone had your foot on the brake?? Can you give me a hint?! And the most important question, what is the thread on the screw?? Did I turn left or right? Regards

Oh Lord, I don't remember when that was

It seems to me that the central screw did not need to be moved. This wheel is bolted with a few small bolts to the timing gear.
I was definitely replacing it myself and rather certainly not using a stroke. But I remember buying some special wrenches for these screws, some like spline only more square.

You only need to unscrew these four eights. You don't need to move the center. You can unscrew them with a normal Torx. A 1/2 ratchet is enough. And the screws are for such wrenches;
