Review HONDA To Four Crankshaft Crank P/n fits CB500 CB550 1971–1976

The **Honda 13300-323-000 Crankshaft** is a meticulously engineered, high-performance component designed exclusively for the legendary **1971 1976 Honda CB500 and CB550** air-cooled, four-stroke motorcycle engines. This forged steel crankshaft is a direct replacement part, meticulously crafted to restore factory specifications and ensure optimal performance, reliability, and longevity in your classic Honda. Engineered with precision, the crankshaft features a **seven-bearing design** (for the CB500) or **eight-bearing design** (for the CB550), providing superior load distribution and reduced internal stress during high-revving operation. The **ground and polished journals** ensure smooth operation, minimizing friction and wear on the main and connecting rod bearings, while the **counterweighted design** helps balance the rotating assembly, reducing vibration and enhancing overall engine smoothness. Built to withstand the demands of modern fuel and high-performance modifications, this crankshaft is made from **high-grade alloy steel**, heat-treated for maximum strength and durability, making it resistant to warping, fatigue, and premature failure. Whether you're restoring a vintage CB500 or CB550 to its original glory or pushing it to the limits with a custom engine build, this OEM-quality crankshaft delivers the reliability and performance expected from Honda s legendary engineering. Perfect for rebuilds, performance upgrades, or replacement of worn-out original components, this part is a must-have for any serious enthusiast looking to preserve or enhance the mechanical integrity of their classic Honda.

### **Pros and Cons of Buying a 1971-1976 Honda CB500/CB550 Crankshaft (Part Number: 13300-323-000)**

1. **Reliability and Durability** Honda s early big-bore engines are known for their robust construction, and the crankshaft is a key component in maintaining long-term performance. A genuine or high-quality aftermarket replacement ensures proper engine function.

2. **Ease of Installation** The crankshaft is a straightforward component to replace, especially if the engine is already out of the bike. It requires basic tools, a press, and careful alignment with the bearings and connecting rods.

3. **Performance Benefits** A fresh crankshaft can restore power output, reduce vibration, and prevent catastrophic failure (such as a broken crank) that could destroy the engine. Many riders report improved smoothness and responsiveness after replacement.

4. **Preventative Maintenance** If the original crankshaft shows signs of wear (cracks, excessive play, or scoring), replacing it early can avoid a costly engine rebuild or replacement.

5. **Availability of Parts** While not as common as modern Honda parts, the crankshaft for these models is still available from reputable suppliers, including:

- **Genuine Honda OEM** (if still in stock)

- **Aftermarket suppliers** (e.g., **Honda Power Equipment, Speedhawk, or eBay sellers with good reviews**)

- **Used/Reconditioned** (from trusted mechanics or restoration shops)

6. **Compatibility** The **13300-323-000** crankshaft fits both the **CB500 (1971-1973)** and **CB550 (1974-1976)**, making it a versatile upgrade for owners of either model.

7. **Cost-Effective Compared to Engine Replacement** Replacing just the crankshaft is far cheaper than buying a used or rebuilt engine, making it a practical solution for restoring a bike.

---

1. **Cost of the Part** A **new OEM or high-quality aftermarket crankshaft** typically ranges from **$200 $400**, depending on the supplier. Used/reconditioned cranks may be cheaper but carry risk if not properly inspected.

- Disassembling the engine (removing pistons, rods, and bearings)

- Using a **crankshaft press** (rental or purchase may be needed)

- Careful alignment to avoid damaging the main bearings or rods

- Reassembly with proper lubrication and torque specifications

- **Labor costs** (if done by a shop) can add **$300 $600 **, depending on location.

3. **Risk of Counterfeit or Low-Quality Parts** Some online sellers may offer **fake or mismachined cranks**, leading to premature failure. Buying from **reputable dealers** (e.g., **Honda-authorized, Speedhawk, or trusted eBay sellers**) reduces this risk.

4. **Additional Wear May Be Present** If the crankshaft is being replaced due to failure, other engine components (bearings, rods, camshaft) may also be worn and require replacement, increasing costs.

5. **Skill Level Required** While not extremely difficult, **engine disassembly/reassembly** demands mechanical skill. Mistakes (e.g., improper bearing fit, cross-threading) can lead to **engine damage or failure**.

6. **Time-Consuming Project** A full engine teardown and crankshaft replacement can take **10 20 hours** for a DIYer, depending on experience.

7. **Potential for Further Issues** If the engine has been neglected, other problems (e.g., seized pistons, damaged cylinders, or a blown head gasket) may surface during the process, requiring additional repairs.

The process is **feasible for experienced mechanics or dedicated DIYers**, but it requires **careful planning, the right tools, and a reliable part source**.

**If the bike is a project or you re comfortable with engine work**, replacing the crankshaft is a **smart investment** that can save money in the long run. However, **if you lack mechanical experience or time**, hiring a **trusted motorcycle mechanic** is the safer option.

---

1. **Verify the Need** Confirm that the crankshaft is indeed the issue (listen for **knocking, excessive vibration, or oil leaks**). A **compression test or engine teardown** may be necessary.

2. **Source the Part Carefully**

- **Best option:** Purchase from a **Honda-authorized dealer** or a **reputable aftermarket supplier** (e.g., **Speedhawk, Honda Power Equipment**).

- **Budget option:** Check **eBay, Facebook Marketplace, or restoration forums** for used/reconditioned cranks, but **inspect for cracks, wear, or damage** before buying.

- **Avoid:** Cheap, untested parts from unknown sellers.

3. **Prepare for the Job**

- Gather **tools** (crankshaft puller/press, torque wrench, gasket scraper, etc.).

- Have **replacement bearings, seals, and possibly rods** on hand in case they re worn.

- Study **Honda service manuals** or **YouTube guides** (e.g., **Motorcycle Mechanics, Bike Bandit**) for step-by-step instructions.

4. **Decide: DIY or Shop Work?**

- **DIY:** If you have **mechanical experience** and **time to dedicate**, this is a rewarding project.

- **Shop Work:** If you re **short on time or confidence**, a **trusted mechanic** ( $400 $800 labor) is the safer choice.

5. **Consider the Big Picture**

- If the rest of the engine is **severely worn**, a **crankshaft replacement alone may not be enough** a **full rebuild or engine swap** could be more cost-effective in the long run.

- If the bike is **not a primary ride**, weigh whether the effort is worth it compared to **buying a used engine or a different bike**.

The bike is a **restoration project** you re committed to.

You have **access to a good part and mechanical skills/labor**.

The **cost of replacement is justified** by the bike s value and your goals.

The engine is **beyond repair** with other major issues.

You **lack time, tools, or confidence** for engine work.

A **used engine or different bike** would be a **better long-term solution**.

For most **serious riders restoring a classic Honda**, this is a **worthwhile upgrade** just **plan carefully and source parts responsibly**.
