Review MERCEDES benz Balance Shaft 2.1l Cdi fits SPRINTER 2017

The **Mercedes-Benz A6510130436 Balance Shaft for the Sprinter B907 2.1L CDI OM651 (2017)** is a precision-engineered component designed to enhance the longevity, performance, and reliability of the iconic OM651 diesel engine found in the 2017 generation of the Mercedes-Benz Sprinter. This balance shaft plays a critical role in mitigating the inherent vibrations generated by the engine s four-cylinder, inline architecture, ensuring smoother operation and reducing wear on critical internal components. Crafted from high-grade, heat-treated steel, the balance shaft is meticulously machined to exacting tolerances, allowing it to rotate at a precisely calibrated speed typically half that of the crankshaft to counteract the dynamic forces produced during combustion cycles. This synchronization minimizes torsional stress on the engine block, connecting rods, and bearings, thereby preventing premature fatigue and extending the overall lifespan of the powertrain. The A6510130436 is a direct-fit replacement, compatible with the 2017 model year of the Sprinter equipped with the 2.1L OM651 CDI engine, ensuring seamless integration with the existing drivetrain without the need for additional modifications. Whether used in commercial, cargo, or passenger configurations, this balance shaft contributes to a quieter, more refined driving experience while maintaining the robust efficiency and torque delivery that Mercedes-Benz engines are renowned for. Its inclusion in a maintenance or rebuild procedure is a proactive measure to preserve the engine s structural integrity, reduce the risk of catastrophic failure, and uphold the vehicle s reputation for durability and performance.

### **Pros and Cons of Buying a Mercedes-Benz A6510130436 Balance Shaft for a 2017 Sprinter (OM651 2.1L CDI, B907)**

1. **Direct Fitment** The part number **A6510130436** is an **OEM balance shaft assembly** specifically designed for the **OM651 2.1L engine** in the **B907 Sprinter (2017 model year)**. This ensures compatibility without modifications, reducing the risk of installation issues.

2. **Improved Engine Balance** The balance shaft helps counteract vibrations caused by the engine s reciprocating and rotating masses, leading to a smoother ride and reduced wear on engine mounts, suspension, and drivetrain components.

3. **Potential Longevity Boost** If the original balance shaft was worn or damaged, replacing it can help prevent excessive stress on the engine block, crankshaft, and other critical components, potentially extending the engine s lifespan.

4. **OEM Quality** As an original equipment part, it meets Mercedes-Benz s manufacturing standards, which generally means better durability compared to aftermarket knockoffs.

5. **Warranty Coverage (if purchased from authorized dealer)** If bought from an official Mercedes-Benz dealer or authorized service center, the part may come with a warranty, providing peace of mind against premature failure.

6. **Prevents Ticking Noise** A failing balance shaft can cause a **ticking or rattling noise** under acceleration or at idle. Replacing it may eliminate this annoyance.

7. **Compatibility with Common Modifications** Since it s an OEM part, it should work well with aftermarket upgrades like turbocharger kits, exhaust systems, or fuel system modifications (assuming they are properly matched).

---

1. **High Cost** OEM balance shaft assemblies are **expensive**, often costing **$800 $1,500 ** depending on the source (authorized dealer vs. third-party seller). This is a significant investment compared to aftermarket alternatives.

2. **Labor-Intensive Installation** Replacing the balance shaft requires **removing the engine cover, disconnecting wiring, and carefully aligning the shaft**, which can take **6 10 hours** of labor. This adds to the total cost if done professionally.

3. **Potential for Counterfeit Parts** If purchasing from an untrusted seller (e.g., eBay, Facebook Marketplace, or non-authorized online retailers), there s a risk of receiving a **fake or substandard part**, which could fail prematurely.

4. **Mixed Reviews on Longevity** Some owners report that even OEM balance shafts fail again after **50,000 100,000 miles**, suggesting that the issue may stem from **engine wear, oil quality, or other related problems** (e.g., worn camshaft bearings, oil pump failure). Simply replacing the balance shaft may not be a permanent fix if the root cause isn t addressed.

5. **Alternative Solutions Exist** Some mechanics recommend **replacing the entire engine cover gasket set** or **upgrading to a high-quality aftermarket balance shaft** (e.g., **Mercedes-specific parts from reputable suppliers like **MBS, **BOSCH, or **MANN-FILTER**) at a lower cost.

6. **Diagnostic Uncertainty** If the ticking noise is caused by something other than the balance shaft (e.g., **camshaft bearings, lifters, or oil pressure issues**), replacing just the balance shaft may not resolve the problem, leading to wasted money.

7. **Environmental & Logistical Challenges** The part may be **heavy and bulky**, making shipping difficult. Some sellers charge extra for expedited shipping, increasing costs.

---

Replacing the **A6510130436 balance shaft** on a **2017 Sprinter OM651 2.1L CDI** is a **legitimate solution** if the issue is confirmed to be the balance shaft. However, it is **not a guaranteed long-term fix** and comes with **high costs and labor requirements**.

If the **ticking noise persists after replacement**, further diagnostics (e.g., **crankshaft/camshaft bearing inspection, oil analysis, or engine rebuild**) may be necessary.

---

- Checking for **oil leaks** around the engine cover.

- Listening for the noise at **different RPMs** (ticking often worsens under load).

- Consulting a **trusted Mercedes specialist** for a **diagnostic scan** (some ticking noises are related to **lifters or camshafts**).

2. **Buy from a Reputable Source**

- **Authorized Mercedes-Benz dealer** (highest quality, warranty coverage).

- **Mercedes-Benz Parts Store (official online)** Ensures authenticity.

- **Trusted aftermarket suppliers** (e.g., **MBS, **BOSCH, or **MANN-FILTER**) if cost is a concern (though OEM is preferred for reliability).

3. **Consider Alternative Fixes**

- If the balance shaft fails again quickly, investigate **oil quality, oil pump performance, or camshaft bearing wear**.

- Some owners report success with **aftermarket balance shaft kits** (e.g., **MANN part # 711 400 0000**) at a lower cost.

4. **Budget for Labor** If DIY installation is attempted, ensure you have the **correct tools and patience**. If not, **get quotes from 2 3 mechanics** to compare labor costs.

5. **Long-Term Strategy**

- If the engine is **high-mileage (150,000 miles)**, consider whether a **full engine rebuild or swap** (e.g., **OM654 or OM642**) might be more cost-effective in the long run.

- If the vehicle is **low-mileage and well-maintained**, the balance shaft replacement may be a **worthwhile fix**.

- The noise is **confirmed to be from the balance shaft**.

- You have **verified the part s authenticity**.

- You are **prepared for the high cost and labor involved**.

- The noise persists after replacement (suggests a deeper issue).

- You find a **reputable aftermarket alternative at a lower price**.

- The vehicle has **other major wear concerns** (e.g., turbo, injectors, suspension).

For most **2017 Sprinter OM651 owners**, this is a **justified repair**, but **due diligence is required** to ensure it s the correct solution.
