Review TRIUMPH Good Used O/h Oiler Part#70-6349 Fitting All Unit Triumphs fits 650

The Triumph 70-6349 Overhead (O/H) Oiler Fitting Unit, designed specifically for the classic Triumph 650cc models like the Bonneville, Thunderbird, and Tiger, represents a meticulously engineered solution for maintaining optimal lubrication in the engine s overhead valve mechanism. This precision-crafted component is a vital part of the engine s valvetrain, ensuring that the rocker arms, pushrods, and valve lifters receive consistent and reliable lubrication under high-stress operating conditions. Crafted from high-quality materials, the fitting unit features a robust, durable construction that resists wear and tear, even after prolonged use, which is essential for preserving the performance and longevity of the engine. The design incorporates a seamless integration with the engine s valve cover, allowing for a secure and leak-free installation that minimizes the risk of oil contamination in the combustion chamber. This fitting unit is particularly noteworthy for its compatibility with the Triumph 650cc s overhead camshaft configuration, where precise oiling is critical to prevent premature wear on the camshaft lobes and valve train components. Whether restoring a vintage Triumph to its former glory or maintaining a well-loved classic, the 70-6349 O/H Oiler Fitting Unit ensures that the engine operates with the smoothness and efficiency it was originally intended to deliver. Its inclusion in any Triumph 650cc restoration or maintenance project underscores the importance of attention to detail in preserving the mechanical integrity and performance of these iconic motorcycles.

### **Pros and Cons of Buying a Triumph 70-6349 Overhead Oiler Fitting Unit (for 650 Triumph Models)**

1. **Compatibility and Fitment** The Triumph 70-6349 is specifically designed for 650cc Triumph motorcycles, including models like the Bonneville, Thunderbird, and Speed Twin. It ensures a proper fit without modifications, reducing the risk of leaks or misalignment.

2. **Improved Lubrication** An overhead oiler fitting unit helps distribute oil more effectively to critical engine components, such as the camshaft, rocker arms, and valve train. This can extend engine life and reduce wear, especially in high-mileage or heavily ridden bikes.

3. **Reduced Noise and Wear** Without proper lubrication, the camshaft and rocker arms can grind against each other, increasing noise and accelerating wear. The overhead oiler mitigates this by ensuring consistent oil flow.

4. **Ease of Installation** The fitting unit is designed to be a straightforward replacement for the stock oiler system. Many riders report that installation takes less than an hour with basic tools, making it a manageable DIY project.

5. **Cost-Effective Upgrade** Compared to a full engine rebuild or replacement, the cost of the oiler fitting unit is relatively low. It provides a significant improvement in engine longevity without a major investment.

6. **Prevents Camshaft Damage** A failing oiler system can lead to dry camshafts, which can strip bearings or damage the cam lobes. The 70-6349 helps prevent this by maintaining proper lubrication.

7. **Aftermarket Support** Triumph and aftermarket suppliers provide this part, meaning it is widely available and backed by warranties or return policies in some cases.

1. **Limited Long-Term Reliability Without Additional Modifications** While the oiler fitting unit improves lubrication, some riders report that it may still require periodic maintenance (e.g., checking oil pressure and ensuring the oil pump is functioning correctly). Without addressing other potential issues (e.g., worn camshaft bearings or a failing oil pump), the benefits may be limited.

2. **Potential for Leaks** If not installed correctly or if the gaskets/seals are not replaced, oil leaks can occur around the fitting unit. This requires careful sealing during installation.

3. **Not a Complete Solution for All Engine Issues** If the engine has other underlying problems (e.g., low oil pressure, worn camshaft bearings, or a failing oil pump), the oiler fitting unit alone may not resolve them. A full engine service or rebuild might still be necessary.

4. **Mixed Reviews on Longevity** Some users report that the oiler fitting unit lasts for years with proper maintenance, while others find that it still fails after a few thousand miles, particularly if the bike is ridden aggressively or in dusty conditions.

5. **Requires Basic Mechanical Knowledge** While installation is relatively simple, it does require familiarity with motorcycle engines. Those without mechanical experience may struggle with tasks like removing the cylinder head or ensuring proper oil flow.

6. **Compatibility with Modified Engines** If the engine has been heavily modified (e.g., with aftermarket cams or different valve springs), the stock oiler fitting unit may not provide optimal lubrication. In such cases, a custom or upgraded oiler system might be needed.

7. **Cost of Replacement Parts** If the oiler fitting unit fails, replacement parts (e.g., seals, gaskets, or the unit itself) can add up over time, especially if the bike is older and parts are harder to source.

The Triumph 70-6349 overhead oiler fitting unit is a worthwhile upgrade for 650cc Triumph models, particularly for riders looking to extend engine life and reduce wear. It is a cost-effective solution that addresses a common issue in older Triumph engines poor lubrication of the camshaft and valve train. However, it is not a universal fix and should be paired with regular maintenance, including oil changes, oil pressure checks, and inspections of the oil pump and camshaft bearings.

For most riders, the benefits outweigh the drawbacks, especially if the bike is used frequently or has high mileage. That said, those with heavily modified engines or limited mechanical experience may need to weigh the pros and cons more carefully or consider additional upgrades.

---

If you own a 650cc Triumph (e.g., Bonneville, Thunderbird, or Speed Twin) and notice increased engine noise, rough valve operation, or concerns about camshaft wear, installing the Triumph 70-6349 overhead oiler fitting unit is a practical and affordable solution. Follow the installation instructions carefully, replace any worn gaskets or seals, and ensure the oil pump is functioning properly.

- Pair this upgrade with regular oil changes (using high-quality motorcycle oil).

- Monitor oil pressure and listen for unusual engine noises.

- Consider a full engine service if the bike has high mileage or shows signs of other wear.

If your engine has other known issues (e.g., low oil pressure, stripped camshaft bearings), address those first, as the oiler fitting unit alone may not be sufficient. For modified engines, research whether additional lubrication modifications are needed.

**Final Verdict:** *Worth the upgrade for most 650cc Triumph owners, provided it is installed correctly and maintenance is maintained.*
