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.

>>16698698 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 , 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.

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.

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;

Topic summary

✨ The discussion revolves around the replacement of the crankshaft pulley with a vibration damper for the Vectra C. Users express concerns about the interchangeability of different pulley versions based on OEM numbers and physical characteristics. It is noted that while some pulleys are interchangeable, differences in design may require different bolt lengths. Recommendations emphasize purchasing from reputable brands to avoid issues with quality, as cheaper alternatives may fail prematurely. Users also share experiences regarding installation techniques and tools needed for the replacement process, highlighting the importance of ensuring compatibility with the vehicle's VIN to select the correct pulley version.
Generated by the language model.

FAQ

TL;DR: The Vectra C crank pulley uses 4 bolts, and “You only need to unscrew these four eights.” Interchangeable options exist; match by VIN and use quality parts. [Elektroda, Anonymous, post #20570281]

Why it matters: This FAQ helps Vectra C owners and techs choose the right damper pulley, avoid fakes, and replace it safely at home.

Quick Facts

Mounting: pulley is secured by four M8 bolts; the center crank bolt stays in place. [Elektroda, Anonymous, post #20570281]
Interchangeability: designs vary in thickness, so some kits include shorter bolts. [Elektroda, grala1, post #16698799]
Fitment: there are 3 versions; selection should be by VIN/OEM number. [Elektroda, szczupx, post #16705954]
Quality: buy branded pulleys; cheap ones require early replacement. [Elektroda, MikeC, post #16698770]
Tools: a 1/2" ratchet and Torx/Ribe driver are sufficient for removal. [Elektroda, Anonymous, post #20570281]

Are Vectra C crankshaft pulleys with vibration dampers interchangeable?

Yes. Users report the wheels are interchangeable despite visual differences. Thickness changes mean bolt length may vary. Choose a branded part. [Elektroda, grala1, post #16698799]

Why do some replacement pulleys come with shorter bolts?

Some pulleys have a thinner hub. A thinner wheel requires appropriately shorter bolts for proper clamping. “If the wheel is thinner, the bolts are shorter.” [Elektroda, Strumien swiadomosci swia, post #16698763]

How many fasteners hold the pulley, and do I loosen the center crank bolt?

Four M8 bolts hold the pulley to the timing gear. Do not touch the central crankshaft bolt during this job. [Elektroda, Anonymous, post #20570281]

Can I replace the pulley at home without an impact gun?

Yes. A 1/2" ratchet is enough to remove the four bolts. An impact gun is not required for this task. [Elektroda, Anonymous, post #20570281]

What tools fit the pulley bolts—Torx, Ribe, or XZN?

You can remove the bolts with a normal Torx. Some sets reference Ribe drivers for these fasteners as well. [Elektroda, Anonymous, post #20570281]

How do I pick the correct pulley by VIN and OEM number?

There are three versions that look similar. Two supersede each other; the third differs. Use your VIN to select correctly. [Elektroda, szczupx, post #16705954]

Which brands are recommended for the Vectra C crank pulley?

Buy from well-known brands. As one expert put it, “buy wheels only from well-known manufacturers.” Cheap units fail early. [Elektroda, MikeC, post #16698770]

What can go wrong with counterfeit or poor-quality pulleys?

Counterfeit parts can look similar but differ inside. One user compared two “original” boxes and saw clear differences after failure. [Elektroda, neket, post #16699983]

Any real-world failure stats I should know?

Yes. A reported new wheel failed after about 20,000 km, revealing sludge instead of proper vulcanized rubber. [Elektroda, neket, post #16699342]

How do I actually swap the pulley?

Secure the car, remove the belt, and align access.
Remove the four M8 bolts with a 1/2" ratchet and Torx/Ribe.
Fit the new pulley, install the correct-length bolts, and torque to spec. [Elektroda, Anonymous, post #20570281]

Do new pulleys include new bolts?

Often yes. Interchangeable kits typically include the appropriate shorter or longer bolts in the box. [Elektroda, MikeC, post #16698770]

Why does my new pulley look different even though the OEM number matches?

Design updates alter hub thickness and bolt length while keeping belt alignment. Visual differences don’t prevent fit. [Elektroda, grala1, post #16698799]

What is the “vibration damper” on the crank pulley?

It’s the rubber-bonded pulley assembly on the crankshaft that absorbs torsional vibrations, as pictured by the OP. [Elektroda, szczupx, post #16698698]

What does VIN mean, and why is it needed here?

VIN is your vehicle identification number. Suppliers use it to select among the three visually similar pulley versions. [Elektroda, szczupx, post #16705954]

Do I need someone on the brake or the car in gear to crack bolts loose?

No. You only remove the four peripheral bolts; a standard 1/2" ratchet is sufficient without braking tricks. [Elektroda, Anonymous, post #20570281]
