### **Analysis of Buying a Used Yanmar 119515-21700 Thermo King 0.57L (2TNV70/TK270M) Crankshaft**

This part is a **crankshaft** (specifically a **2TNV70** engine crankshaft) for a **Thermo King 0.57L refrigeration unit**, likely used in commercial refrigerated transport. Below is a detailed breakdown of the pros and cons of purchasing it, followed by a conclusion and recommendation.

---

### **Pros of Buying This Crankshaft**

1. **High Quality and Durability**

- Yanmar engines are known for their reliability, precision engineering, and long service life, especially in heavy-duty applications like refrigerated transport.

- The **2TNV70** is a robust inline-4 diesel engine commonly used in commercial refrigeration units, meaning it has been tested in demanding conditions.

- A well-maintained crankshaft from a Yanmar engine should last **100,000 miles** with proper upkeep, making it a cost-effective long-term investment.

2. **Compatibility and Aftermarket Availability**

- The **0.57L** Thermo King unit is a well-documented model, and parts like crankshafts are relatively easy to source, either new or used.

- Many mechanics and repair shops specialize in **Yanmar diesel engines**, ensuring easier maintenance and troubleshooting.

- If the engine is **2TNV70-based**, replacement parts (connecting rods, bearings, seals) are widely available, reducing downtime.

3. **Potential for Engine Rebuild or Restoration**

- If the crankshaft is **mildly worn or damaged**, it may be repairable rather than needing full replacement.

- Some used crankshafts can be **reconditioned** (grinding, balancing, or replacing journals) at a fraction of the cost of a new one.

- A **rebuilt engine** with a refurbished crankshaft can extend the life of the refrigeration unit significantly.

4. **Cost-Effective Alternative to New Parts**

- New Yanmar crankshafts can be **expensive** (often **$1,500 $3,000 ** depending on the model).

- A used or rebuilt crankshaft can cost **30 70% less**, making it a budget-friendly option for fleet operators or independent repair shops.

- If the engine is **non-running but structurally sound**, purchasing just the crankshaft (rather than the entire engine) can be a smart financial move.

5. **Environmental and Economic Benefits**

- Buying used reduces **waste** compared to discarding a functional engine component.

- It supports **recycling of industrial parts**, which can be beneficial for businesses looking to reduce operational costs sustainably.

### **Cons of Buying This Crankshaft**

1. **Risk of Hidden Damage or Wear**

- Without a **full inspection**, a used crankshaft may have **internal cracks, bent journals, or excessive wear** on the main bearings.

- **Rod bearing journals** and **main bearing surfaces** can fail catastrophically if not properly checked via **micrometer measurements** or **bore scope inspection**.

- If the crankshaft was removed due to **severe engine failure** (e.g., seized bearings, broken rods), it may require **major refurbishment**, increasing costs.

2. **Unknown Service History**

- If the crankshaft was pulled from an engine with **poor maintenance**, it may have **carbon buildup, rust, or misalignment** issues.

- Lack of **service records** means you cannot verify if the engine was **properly lubricated, cooled, and inspected** before failure.

- Some sellers may **misrepresent the condition** (e.g., claiming it s "good as new" when it has **microscopic cracks**).

3. **Potential for Counterfeit or Salvaged Parts**

- The **Yanmar 2TNV70** is a **high-demand part**, making it a target for **counterfeit or salvaged (scrapyard) components**.

- Some sellers may **machine-marked parts** to hide defects or **use mismatched components** (e.g., wrong material grade).

- **No warranty** is typically provided with used parts, meaning you bear **full responsibility** for any failures.

4. **Additional Costs Beyond Purchase Price**

- **Replace bearings, seals, and gaskets** (often **$500 $1,500** extra).

- **Rebalance the crankshaft** (if out of spec, costing **$200 $600**).

- **Machine the journals** (if worn, **$300 $1,000** depending on severity).

- **Reassemble the engine** (labor costs can add **$1,000 **).

- If the **block or cylinder head** is damaged, the repair bill can **exceed $5,000**.

5. **Risk of Engine Rebuild Complexity**

- Replacing just the crankshaft often requires **full engine disassembly**, which is **labor-intensive**.

- If the **connecting rods, pistons, or camshaft** are also worn, they must be replaced simultaneously, increasing costs.

- **Specialized tools** (e.g., crankshaft puller, alignment tools) may be needed, adding to expenses.

6. **Potential for Reduced Engine Performance**

- Even if the crankshaft is **mechanically sound**, an engine rebuilt with **mixed-condition parts** may **lose power, efficiency, or reliability**.

- If the **timing or balance** was not properly restored, it could lead to **vibration, oil leaks, or premature failure** of other components.

7. **Limited Warranty or Return Options**

- Used parts **rarely come with warranties**, meaning if the crankshaft fails shortly after installation, you are **fully responsible for repairs**.

- Some sellers may offer a **short-term guarantee (30 90 days)**, but this is **not standard** and should be negotiated upfront.

---

### **Key Considerations Before Purchase**

1. **Get a Professional Inspection**

- **Journal wear** (should be within **0.002" 0.003" clearance** for new bearings).

- **Cracks or pits** (visible via **magnetic particle inspection** or **dye penetrant testing**).

- **Balancing** (should be within **Yanmar s specified tolerances**).

- **Surface finish** (should be smooth, not corroded or pitted).

2. **Verify Engine Condition**

- If possible, inspect the **entire engine block, cylinder head, and other components** to ensure they are **not severely worn**.

- Check for **oil leaks, coolant contamination, or exhaust smoke issues** that could indicate **internal damage**.

3. **Compare Pricing Across Sellers**

- Used Yanmar crankshafts can vary **widely in price** ($300 $1,500 depending on condition).

- **Auction sites, industrial scrap dealers, and fleet parts suppliers** often have different pricing **shop around**.

- Beware of **extremely low prices**, which may indicate **hidden defects**.

4. **Consider New vs. Rebuilt vs. Used**

- **New crankshaft**: Most reliable but **expensive**.

- **Rebuilt (machine shop)**: Good balance of cost and reliability if inspected properly.

- **Used (as-is)**: Cheapest but **highest risk** only suitable for **experienced mechanics** who can verify condition.

5. **Check for Alternatives**

- **Remanufactured Yanmar engines** (some suppliers offer **full rebuilds with warranties**).

- **Alternative brands** (e.g., **Isuzu, Cummins, or Perkins**) if compatibility allows.

- **Leasing or renting** a refrigeration unit if the repair cost is prohibitive.

---

### **Conclusion**

- You **thoroughly inspect** the part for damage.

- You **budget for additional repairs** (bearings, seals, labor).

- You **have access to a skilled mechanic** who can verify its condition.

- The **engine block and other components** are in **decent shape**.

- **Undetected defects** leading to **engine failure**.

- **Hidden repair costs** that could **exceed the savings** of buying used.

- **No warranty protection**, meaning you bear **full financial responsibility**.

For **fleet operators or businesses with limited mechanical expertise**, a **new or remanufactured crankshaft** (with warranty) may be the **safer long-term investment**, despite the higher upfront cost.

For **experienced mechanics or repair shops** with **access to inspection tools**, a **well-vetted used crankshaft** can be a **smart purchase
