Review MERCEDES benz New Genuine Crankshaft Gear fits W107 W126
The **Mercedes-Benz 1160520603 Crankshaft Gear** is a precision-engineered component designed exclusively for the iconic **W107 (1979 1985) and W126 (1984 1991) model series**, specifically the **300 SE, 300 SEL, 300 SD, 500 SE, 500 SEL, and 560 SEL** variants powered by the legendary **M117 and M116 inline-six engines**. This high-performance gear is a critical part of the **crankshaft assembly**, directly interfacing with the **oil pump** and **timing system** to ensure seamless operation of the engine s internal mechanics. Crafted from **high-grade alloy steel**, the gear is machined to exacting tolerances, featuring a **precision-cut helical tooth profile** that minimizes noise, reduces wear, and optimizes lubrication efficiency essential for maintaining the smooth, refined power delivery these Mercedes-Benz models are renowned for. The **1160520603** part number denotes its compatibility with both the **3.0L and 3.5L M117 engines** (W107) and the **3.0L M116 engines** (W126), making it a versatile replacement for engines exhibiting symptoms of **excessive crankshaft gear wear**, such as **oil leaks, unusual engine noises, or timing-related malfunctions**. This component is particularly vital for owners seeking to restore or enhance the performance of their classic Mercedes, as its failure can lead to catastrophic engine damage due to improper oil circulation or timing misalignment. When installed, the **1160520603 crankshaft gear** integrates seamlessly with the **crankshaft sprocket, oil pump drive gear, and timing chain**, ensuring that the engine s critical lubrication and timing functions operate with the precision and reliability expected from Mercedes-Benz s legendary engineering. For restoration projects or routine maintenance, this gear is a must-have replacement part, offering both durability and the performance integrity that defines these timeless luxury sedans.
### **Pros and Cons of Buying a Mercedes-Benz 1160520603 (W107/W126 Crankshaft Gear)**
#### **Pros:**1. **Rarity and Collectibility** The W107 (1979 1985) and W126 (1985 1991) are iconic Mercedes-Benz models, particularly the 300SEL and 500SEL, which are highly sought after by enthusiasts. A crankshaft gear from this era is a rare mechanical component, making it valuable for restoration or display purposes.
2. **Historical Significance** These models represent the pinnacle of Mercedes-Benz engineering in the late 20th century, featuring advanced features like air suspension, luxury interiors, and powerful M116/M117 engines. Owning a part from this era adds authenticity to a restoration project.
3. **Potential for Restoration Value** If you are restoring a W107 or W126, this crankshaft gear may be difficult to source new or even in good used condition. Replacing it with an original or high-quality replica could enhance the car s value and authenticity.
4. **Engineering Quality** Mercedes-Benz parts from this era were built to last, with precision machining and durable materials. A well-maintained crankshaft gear can provide reliable performance in a restored engine.
5. **Market Demand for Classic Mercedes Parts** The classic car market continues to grow, and parts for W107/W126 models are increasingly difficult to find. Owning this gear ensures you have a piece of automotive history that may appreciate in value over time.

#### **Cons:**1. **High Cost** Due to rarity, this part may be expensive, especially if it is original or in excellent condition. Reproduction parts may be available but could compromise authenticity.
2. **Difficulty in Installation** The W107/W126 engines are complex, and replacing a crankshaft gear requires specialized tools, mechanical skill, and potentially engine disassembly. If you lack experience, labor costs could be prohibitive.
3. **Compatibility Issues** If the part is not an exact match (e.g., a reproduction), it may not fit perfectly or could require additional modifications, such as machining or gasket adjustments.
4. **Risk of Counterfeit or Low-Quality Replacements** The aftermarket for classic Mercedes parts is not always trustworthy. A poorly made crankshaft gear could lead to engine damage if it fails prematurely.
5. **Maintenance and Storage Challenges** If you are not actively restoring a W107/W126, storing this part properly (in a dry, temperature-controlled environment) is essential to prevent corrosion or degradation.
6. **Time-Consuming Restoration Process** Restoring a W107 or W126 is a labor-intensive project that may take months or years, depending on your resources. Purchasing this part without a clear plan could lead to frustration or financial strain.

### **Conclusion:**Buying a Mercedes-Benz 1160520603 crankshaft gear (W107/W126) is a significant investment with both tangible and intangible benefits. If you are a serious collector, restorer, or enthusiast with the technical skills and patience to work on these models, the part could be a valuable addition to your project. However, if you lack experience, time, or financial flexibility, the risks including high costs, installation challenges, and potential compatibility issues may outweigh the rewards.
### **Recommendation:**- **If you are restoring a W107 or W126 and need this part for authenticity**, proceed with caution. Verify the part s origin (original vs. reproduction), ensure compatibility with your engine, and budget for professional installation if necessary.
- **If you are not actively restoring a car**, consider whether the part s value justifies storage costs and potential depreciation. Alternatively, explore less rare but still high-quality alternatives if your primary goal is functionality rather than collectibility.
- **For beginners**, consult with a trusted Mercedes specialist or restoration shop before purchasing to assess whether this is the right step for your project. Prioritize parts that are easier to source and install if you are still learning.
- **If buying for investment purposes**, research current market trends for W107/W126 parts to ensure the gear will hold or increase in value over time.
Ultimately, this purchase is best suited for dedicated enthusiasts who understand the challenges and rewards of working with these legendary Mercedes-Benz models.
