Review FREIGHTLINER Rear Engine Support Mount Columbia Detroit 60 fits CENTURY

The **Freightliner 01-23728-001 Rear Engine Mount** and **01-22935-001 Century Detector Engine Mount** are high-performance, heavy-duty suspension components specifically engineered for Freightliner Century and Detroit Series 60 diesel-powered trucks, covering model years from the early 2000s through the early 2010s. These mounts are critical components of the engine support system, designed to absorb vibrations, isolate engine noise, and maintain proper alignment between the powertrain and the chassis, ensuring optimal drivability, longevity, and reliability under the demanding conditions of commercial and heavy-duty applications. Crafted from durable, high-grade materials, including reinforced rubber compounds and robust steel reinforcements, these mounts are built to withstand the extreme forces generated by high-torque diesel engines while resisting wear, cracking, and deformation over extended periods of use. The **01-23728-001** serves as the primary rear engine mount, anchoring the engine block or transmission housing to the frame, while the **01-22935-001 Century Detector** acts as a secondary or auxiliary mount, often positioned near the exhaust manifold or turbocharger area to further dampen vibrations and reduce stress on the primary mount. Both components are precision-molded to fit seamlessly with Freightliner s proprietary mounting points, ensuring a secure and stable connection that minimizes lateral and vertical movement, thereby reducing strain on the engine mounts, drivetrain components, and surrounding chassis elements. Whether installed in a long-haul truck, a regional delivery vehicle, or a heavy-duty work truck, these mounts contribute to a smoother ride, reduced cab noise, and improved fuel efficiency by preventing unnecessary energy loss through excessive vibration. Replacing worn or failed engine mounts is a straightforward yet essential maintenance task, as compromised mounts can lead to costly damage to the engine, transmission, or exhaust system, not to mention compromised handling and safety. For fleets and independent operators seeking to maintain peak performance and extend the lifespan of their Freightliner Century or Detroit 60 powertrains, these OEM-quality mounts represent a reliable, cost-effective solution that aligns with the rigorous demands of commercial transportation.

### **Pros of Purchasing These Parts**

1. **Compatibility with Classic Trucks**

- These mounts are designed specifically for Freightliner models (e.g., FL450, FL500, FL600) with the **Detroit 60-series engine**, making them a direct fit for owners restoring or maintaining these trucks.

- The Century series (e.g., Century Class 8 trucks) also used this engine, so these mounts are relevant for those models as well.

2. **Reliability of the Detroit 60-Series Engine**

- The **Detroit Series 60** is known for its durability and longevity, especially when properly maintained. Many of these engines still run reliably in older trucks.

- The engine s robust construction makes it a good choice for heavy-duty applications, such as long-haul or regional freight.

3. **Ease of Availability (Used Market)**

- Since these parts are from an older generation, they are often found in used or salvage yards at lower costs compared to newer OEM parts.

- Aftermarket alternatives (e.g., from **Melling, Monroe, or other engine support manufacturers**) may also be available, offering cost-effective solutions.

4. **Simpler Maintenance Compared to Modern Engines**

- The Detroit 60-series engine is relatively straightforward to work on, with widely available repair manuals and a strong community of mechanics familiar with it.

- Many components are interchangeable with other Detroit engines (e.g., Series 71), reducing long-term part-sourcing issues.

5. **Potential for Customization and Upgrades**

- Owners can easily upgrade components like turbochargers, injectors, or fuel systems to improve performance.

- The engine s mechanical simplicity allows for DIY modifications, such as rebuilding the engine or upgrading the exhaust system.

---

### **Cons of Purchasing These Parts**

1. **Age-Related Wear and Availability of Original Parts**

- The **rear engine mounts (01-23728-001 and 01-22935-001)** are older designs and may not be as robust as modern mounts, which often incorporate advanced rubber compounds and mounting technologies.

- Over time, these mounts can degrade due to heat, vibration, and exposure to road debris, leading to premature failure if not replaced regularly.

2. **Potential for Compatibility Issues**

- While these mounts fit Freightliner and Century trucks with the Detroit 60-series engine, **aftermarket or remanufactured parts may not always align perfectly** with the truck s frame or engine bay.

- Some newer or modified trucks (e.g., those with lifted suspensions or aftermarket engine supports) may require additional modifications to accommodate these mounts.

3. **Limited Warranty or Support**

- Purchasing these parts from salvage yards or aftermarket suppliers may mean **no warranty or limited return policies**, unlike OEM parts from Freightliner or Detroit Diesel.

- If the mounts fail shortly after installation, the owner may bear the full cost of replacement.

4. **Maintenance and Longevity Concerns**

- The **Detroit 60-series engine**, while durable, requires **regular maintenance** (e.g., valve adjustments, fuel system cleaning, and timing belt replacements) to avoid catastrophic failure.

- Older engines are more prone to **carbon buildup, injector issues, and turbocharger wear** if not properly serviced, which can lead to higher long-term costs.

5. **Environmental and Emissions Regulations**

- Many older Detroit 60-series engines **do not meet modern emissions standards** (e.g., EPA 2007 or Euro VI), which could be a problem if the truck is used in regulated fleets or for certain types of work.

- Retrofitting emissions control systems (e.g., DEF injectors, EGR coolers) can be costly and may not be worth it for older trucks.

6. **Difficulty Finding Skilled Mechanics**

- While the engine is simple, **fewer mechanics today specialize in older Detroit engines**, which can make repairs more expensive or time-consuming.

- Finding OEM or high-quality aftermarket parts for these systems may require searching multiple suppliers.

### **Conclusion**

Purchasing the **Freightliner rear engine mounts (01-23728-001 & 01-22935-001) for a Century Detroit 60-series engine** can be a **cost-effective and practical choice** for owners of classic Freightliner or Century trucks who prioritize reliability and simplicity. The **Detroit 60-series engine remains a solid workhorse** when maintained properly, and these mounts are essential for keeping the engine supported and stable.

However, **potential drawbacks include limited availability of high-quality parts, maintenance demands, and compatibility issues** with modern or heavily modified trucks. Additionally, **emissions concerns and the need for regular upkeep** may make these engines less ideal for long-term or high-mileage use without significant investment.

---

### **Recommendation**

- **Buy these parts if:**

- You own a **Freightliner or Century truck with a Detroit 60-series engine** and need reliable, budget-friendly replacements.

- You are **restoring or maintaining a classic truck** and can commit to regular maintenance.

- You are comfortable with **DIY repairs** or have access to a mechanic experienced with older Detroit engines.

- You plan to **keep the truck in light-to-moderate use** (e.g., occasional hauling, towing, or short-haul work).

- **Consider alternatives if:**

- You need **modern emissions-compliant parts** and are open to upgrading to a newer Detroit engine (e.g., Series 60 with emissions upgrades or a Series 71/85).

- You want **longer warranties and better support**, in which case **OEM or high-quality aftermarket mounts** (e.g., from **Melling or Monroe**) may be worth the higher cost.

- You are running the truck **heavily or in harsh conditions**, where newer mounts with advanced materials (e.g., polyurethane or synthetic rubber) would provide better durability.

- You struggle to find **skilled mechanics** for older engines, as repairs could become costly.

**Final Verdict:**

For **enthusiasts or owners of classic Freightliner/Century trucks** who value cost savings and simplicity, these mounts are a **practical and reasonable choice**.
