The **AP 28473WWRJ** is a high-performance, direct-fit front left base engine mount specifically engineered for the **1987 Mercedes-Benz 300D (W123)** with the **OM617 diesel engine**. Designed to replace the original rubberized suspension component, this mount is crafted from durable, high-grade **polyurethane**, a material renowned for its superior strength, longevity, and resistance to oil, heat, and environmental degradation qualities that far exceed those of conventional rubber mounts. The **WWRJ** designation indicates a precise fit for the left-hand side of the engine bay, ensuring seamless integration with the engine block, transmission, and firewall, while maintaining the vehicle s factory alignment and suspension geometry. Unlike standard mounts that can degrade over time due to oil leaks, road debris, or temperature fluctuations, this polyurethane alternative maintains its structural integrity, reducing engine movement and vibration for a noticeably smoother ride and enhanced drivability. The mount s robust construction also helps mitigate stress on the engine s supporting components, potentially extending the lifespan of related parts such as the subframe, transmission mounts, and even the engine itself. Ideal for both restoration projects and daily drivers seeking improved ride quality and durability, the **AP 28473WWRJ** is a meticulously crafted replacement that adheres to Mercedes-Benz engineering standards while offering modern performance benefits. Its precise fitment ensures compatibility with aftermarket modifications, such as performance exhaust systems or suspension upgrades, making it a versatile choice for enthusiasts looking to enhance their 300D s handling and reliability.
### **Pros and Cons of buying a AP 28473WWJR for a 1987 Mercedes-Benz 300D Front Left Engine Mount**
#### **Pros:**1. **OEM Replacement Part** The AP (Automotive Parts) 28473WWJR is a direct replacement for the original Mercedes-Benz engine mount, ensuring compatibility with the 1987 300D s suspension and engine bay layout. This reduces the risk of fitment issues compared to aftermarket alternatives that may not align perfectly.
2. **Durability and Quality** AP parts are generally manufactured to meet or exceed OEM standards, using materials designed for longevity. The rubber and metal components are engineered to handle the vibrations and stresses of a diesel engine like the OM617 in the 300D, reducing premature wear.
3. **Warranty Coverage** Many AP parts come with a manufacturer s warranty (typically 1 2 years), providing peace of mind against defects in materials or workmanship. This is particularly useful if the mount fails shortly after installation.
4. **Ease of Installation** Since it is a direct replacement, the AP mount should install similarly to the original, requiring minimal modifications. This makes it a straightforward DIY project for those with basic mechanical skills, or it can be easily installed by a mechanic.
5. **Compatibility with Aftermarket Upgrades** If you ve modified your 300D (e.g., turbocharging, suspension adjustments, or weight changes), a high-quality OEM-style mount like this one helps maintain proper engine positioning and damping, which is critical for performance and drivability.
6. **Reliability for Long-Term Use** The 300D s engine mount is a critical component that supports the weight of the engine and transmission. A well-made replacement like this one reduces the risk of engine sagging, excessive vibration, or transmission misalignment over time.
7. **Accessibility and Availability** AP parts are widely distributed through automotive retailers, online marketplaces, and specialty Mercedes-Benz shops. This makes it easier to source the part quickly, especially for older model vehicles where OEM replacements may be harder to find.

#### **Cons:**1. **Cost** While not excessively expensive, the AP 28473WWJR is priced higher than some aftermarket alternatives. For a 1987 300D, the cost may be a consideration if you re working with a tight budget, especially if you need to replace multiple mounts or related components.
2. **Potential for Counterfeit or Low-Quality Copies** When purchasing online (e.g., from third-party sellers), there is a risk of receiving a counterfeit or substandard part that doesn t meet AP s quality standards. Always buy from reputable sellers with return policies and verify the part s authenticity.
3. **Limited Customization** Unlike some aftermarket mounts, this is a standard OEM replacement with no adjustable features. If you need a mount with different damping characteristics (e.g., for reduced vibration or improved isolation), you may need to explore specialized aftermarket options.
4. **Installation Challenges** While designed for easy replacement, rusted bolts or corroded mounting points in an older 300D can make installation difficult. You may need penetrating oil, heat, or even replacement of the mounting hardware (e.g., bolts or washers) to ensure a secure fit.
5. **Wear Over Time** Even high-quality mounts will degrade over time due to age, heat, and exposure to engine fluids. The rubber component may crack or harden, requiring eventual replacement. This is not unique to the AP part but is a general consideration for all engine mounts.
6. **Potential for Misalignment** If the mount is not installed correctly (e.g., bolts not tightened to specification or the mount not seated properly), it can lead to engine drift, transmission slippage, or increased vibration. This underscores the importance of following the manufacturer s installation instructions carefully.

### **Conclusion:**The **AP 28473WWJR** is a solid choice for replacing the front left engine mount on a 1987 Mercedes-Benz 300D. It offers the reliability and compatibility of an OEM-style part with the added benefit of AP s quality control. For most owners, the pros such as durability, warranty coverage, and ease of installation outweigh the cons, which are largely manageable (e.g., cost, potential counterfeit risks, or installation challenges).
If you prioritize **long-term reliability, ease of installation, and peace of mind**, this part is a strong recommendation. However, if you re on a tight budget or seeking **customized damping properties**, you may want to compare it with aftermarket alternatives (e.g., Eurosport, Febi, or specialized suspension brands) that offer similar performance at a lower cost.
