Experiencing play in your AC compressor pulley on your Mercedes-Benz C230 Kompressor? Like many owners, you might initially think a complete compressor replacement is the only solution. However, there’s good news! Replacing just the bearing within the clutch pulley is a viable, and significantly more cost-effective, alternative. This approach can save you hundreds of dollars compared to replacing the entire AC compressor, which involves refrigerant evacuation and recharge.
It’s been discovered through online automotive communities and even confirmed by a Mercedes-Benz technical service bulletin that replacing the AC compressor clutch bearing while the compressor remains in the vehicle is indeed possible. This eliminates the complexities and costs associated with a full compressor swap.
However, the challenge lies in identifying the specific bearing needed for your 2003 Mercedes-Benz C230 Kompressor clutch kit. Many owners have encountered difficulties pinpointing the correct component for this repair.
Let’s delve into the details and explore how to find the right clutch bearing for your Mercedes C230 Kompressor.
Identifying Your AC Compressor: A Denso 7SEU10c Model
To start, correctly identifying your AC compressor model is crucial. Typically found on a label affixed to the compressor unit, this information is key to sourcing the right parts. In the case of the 2003 Mercedes-Benz C230 Kompressor, many are equipped with a Denso 7SEU10c compressor.

As seen in the example image, the label clearly indicates a Denso model 7SEU10c with the Denso part number 447180-9712. While online parts catalogs, like the Denso catalog, suggest the current Denso replacement model for M271 engines might be #471-1580, finding the individual bearing remains a hurdle.
The Quest for the Correct Clutch Bearing
Despite identifying the compressor model, sourcing the precise bearing for just the clutch pulley has proven difficult for many Mercedes-Benz C230 Kompressor owners. While complete pulley/clutch assemblies are available, often around the $200 price point, the goal is a more economical repair by replacing only the bearing.
Numerous sizes of bearings are used in Denso AC compressors, adding to the confusion. However, progress has been made by searching for complete clutch pulleys. These searches have revealed that some online vendors specify the bearing dimensions as 35x52x22mm.
Furthermore, examining images of these clutch pulleys indicates that the bearing is secured within the pulley by small divots stamped into the surrounding ring. This raises a question about the feasibility of removing the old bearing and installing a new one without damaging the pulley, which is often made of plastic.
Fortunately, clutch pulleys themselves appear to be available from manufacturers like TTK, found on platforms like eBay, at a more reasonable $50-70. While the reliability of brands like TTK might require further investigation, they claim to source bearings from Chinese companies C&U and Taide.
Conclusion: Towards a Cost-Effective AC Repair
Replacing just the clutch bearing on your 2003 Mercedes-Benz C230 Kompressor AC compressor is a smart way to save money and avoid unnecessary system disruption. While finding the exact bearing specification can be challenging, focusing on clutch pulley assemblies and the bearing dimensions they list (35x52x22mm) offers a promising path forward.
As the search continues for the definitive bearing part number, exploring readily available clutch pulleys from brands like TTK could be a viable alternative for a more affordable Mercedes Benz 2003 C230 Kompressor Clutch Kit solution. Continued community feedback and shared experiences are invaluable in pinpointing the ideal bearing for this common Mercedes-Benz repair.
