Review MERCEDES benz Crankshaft Seal 2.1 Cdi fits SPRINTER 2014–2018

The **Mercedes-Benz A6510110108 Crankshaft Seal** is a precision-engineered, high-performance aftermarket replacement designed specifically for the **Mercedes-Benz Sprinter (W907/B907) models equipped with the 2.1L OM651 CDI diesel engine**, covering production years from **2014 to 2018**. This seal is a critical component of the engine s front cover assembly, ensuring optimal sealing between the crankshaft and the engine block to prevent oil leaks, maintain proper lubrication, and preserve engine integrity over time. Crafted from **high-quality, oil-resistant elastomer materials**, this seal is engineered to withstand the demanding conditions of continuous engine operation, including high temperatures, pressure fluctuations, and exposure to diesel fuel and engine oils, all while delivering long-lasting durability and reliability.

The **A6510110108** is meticulously manufactured to meet or exceed OEM specifications, featuring a **perfectly contoured lip design** that ensures a tight, consistent seal around the crankshaft s splined surface, minimizing the risk of oil leakage and contamination. Its robust construction incorporates **reinforced backing rings and precision-molded lips**, which enhance flexibility and resilience, allowing it to accommodate minor engine movements and vibrations without compromising its sealing effectiveness. This seal is particularly well-suited for the **OM651 engine**, which is known for its robust yet intricate design, requiring components that balance performance with longevity.

Installation of the **Mercedes-Benz A6510110108 Crankshaft Seal** is straightforward yet requires careful attention to detail to ensure proper fitment and functionality. The seal is designed to be a **direct drop-in replacement**, compatible with the original equipment dimensions and mounting points, eliminating the need for modifications to the engine bay. However, it is essential to follow **Mercedes-Benz service procedures** or consult a professional mechanic to ensure the old seal is removed without damaging the crankshaft or surrounding components. Proper installation involves cleaning the crankshaft splines thoroughly, applying a thin layer of **high-temperature engine grease** to the seal s lip to facilitate smooth installation and reduce wear during the break-in period.

Beyond its primary function of preventing oil leaks, this crankshaft seal contributes to the overall **efficiency and longevity** of the OM651 engine. By maintaining a secure barrier between the internal lubrication system and the external environment, it helps prevent oil dilution with fuel, reduces carbon buildup on intake valves, and minimizes the risk of engine damage caused by oil starvation or contamination. The **A6510110108** is an ideal choice for fleet operators, commercial drivers, and DIY enthusiasts who prioritize **cost-effective, high-quality replacements** that extend the life of their Sprinter s engine while adhering to Mercedes-Benz standards.

For those seeking a **trusted, aftermarket solution**, this seal is backed by rigorous quality control processes and is often recommended by mechanics specializing in diesel engines. Its compatibility with the **2.1L OM651 CDI** ensures seamless integration with the Sprinter s powertrain, making it a reliable upgrade for vehicles experiencing **crankshaft seal failure symptoms**, such as oil leaks around the front cover, unusual engine noises, or a burning oil smell. Whether used as a **preventative replacement** during routine maintenance or as a **direct repair solution**, the **Mercedes-Benz A6510110108 Crankshaft Seal** delivers the performance and reliability expected from a genuine-quality aftermarket part.

### **Pros and Cons of Buying a Mercedes-Benz A6510110108 Crankshaft Seal for Sprinter W907/B907 (2.1 CDI OM651, 2014 2018)**

1. **OEM Quality** The A6510110108 is a genuine Mercedes-Benz part, meaning it meets the manufacturer s exact specifications for durability, sealing performance, and compatibility with the OM651 engine. This reduces the risk of premature failure or leaks compared to aftermarket alternatives.

2. **Reliability and Longevity** OEM crankshaft seals are designed to withstand the high pressures and temperatures found in diesel engines like the OM651. When installed correctly, they can last the life of the engine, provided there are no underlying issues (e.g., oil leaks, misalignment).

3. **Warranty Coverage** Purchasing from an authorized dealer or Mercedes-Benz approved supplier may include warranty protection, offering peace of mind in case of defects. Some third-party sellers also offer limited warranties, though these vary by provider.

4. **Exact Fitment** The part is engineered specifically for the W907/B907 Sprinter chassis and OM651 engine, ensuring a proper seal without gaps or misalignment that could lead to oil leaks or engine damage.

5. **Easier Installation** Since it is the correct part, it should fit without modifications, reducing the risk of installation errors that could void warranties or cause further damage.

6. **Resale Value** Using OEM parts can be beneficial if you plan to sell the vehicle later, as buyers often prefer vehicles with original equipment components.

---

1. **Higher Cost** OEM parts are significantly more expensive than aftermarket alternatives. The A6510110108 can cost **$150 $300 **, depending on the supplier, whereas aftermarket seals may range from **$30 $80**. This can be a major consideration for DIYers or those on a tight budget.

2. **Limited Availability** Genuine OEM parts may not always be in stock at local dealers, requiring online purchases (e.g., from **Mercedes-Benz Parts Store, Amazon, or specialty suppliers**), which can involve shipping delays or higher fees.

3. **Potential Counterfeit Risks** Buying from untrusted sellers (especially online marketplaces) increases the risk of receiving a **fake or low-quality part**. Always verify the seller s reputation and check for authenticity markings (e.g., Mercedes-Benz holograms, serial numbers).

4. **Labor Costs** While the seal itself is straightforward to replace, improper installation (e.g., not torquing bolts correctly, using the wrong gasket) can lead to leaks. If hiring a mechanic, labor costs (typically **$150 $300**) can add to the total expense.

5. **Overkill for Some Owners** If the vehicle is older or high-mileage, some owners may opt for aftermarket seals that offer similar performance at a fraction of the cost. However, for those prioritizing longevity and reliability, the OEM part is worth the investment.

6. **Environmental and Ethical Concerns** OEM parts contribute to electronic waste when disposed of improperly. Some buyers may prefer aftermarket or remanufactured parts as a more sustainable option.

### **Conclusion**

The **Mercedes-Benz A6510110108 crankshaft seal** is the **best choice for reliability, longevity, and peace of mind** for the OM651 engine in the W907/B907 Sprinter. Its OEM quality ensures a proper fit, reduces the risk of leaks, and aligns with the manufacturer s standards. However, the **higher cost and potential counterfeit risks** make it less ideal for budget-conscious buyers or those who prioritize cost savings over brand assurance.

For most owners who want **long-term performance and warranty protection**, the OEM part is justified. If budget is a concern, **high-quality aftermarket alternatives** (e.g., **Fel-Pro, Gates, or Bosch**) can offer comparable performance at a lower price, provided they are from reputable brands.

---

### **Recommendation**

1. **Buy from an Authorized Source** Purchase the part from **Mercedes-Benz Parts Store, an official dealer, or a trusted online retailer** (e.g., **RockAuto, eBay verified sellers, or Amazon with positive reviews**). Avoid unknown sellers to prevent counterfeit parts.

2. **Verify the Part Number** Double-check that the part number matches your engine and vehicle model (A6510110108 for OM651). Some seals may look similar but have different internal designs.

3. **Consider Aftermarket if Budget is Tight** If you re confident in your mechanical skills and the vehicle isn t high-mileage, a **reputable aftermarket seal** (e.g., **Fel-Pro 52000 or Gates**) can be a cost-effective alternative without sacrificing quality.

4. **Proper Installation is Critical** Whether using OEM or aftermarket, ensure the **crankshaft is clean, the new seal is properly lubricated, and bolts are torqued to spec** (typically **25 Nm for the seal retainer bolts**). Improper installation is the leading cause of leaks.

5. **Monitor for Leaks Post-Installation** After replacement, check for oil leaks around the seal for the first **100 200 miles**. If leaks persist, recheck the installation or consider professional help.

For **most Sprinter owners**, the **A6510110108 OEM crankshaft seal is the best long-term solution**, balancing reliability with Mercedes-Benz standards. However, if cost is a major factor, a **high-quality aftermarket seal from a trusted brand** can be a practical alternative. Always prioritize **authenticity and proper installation** to avoid future issues.
