Review YAMAHA New Oem Lock Washer Nos

The **Yamaha 90215-10006-00 Lock Washer** is a precision-engineered fastening solution designed to ensure secure, vibration-resistant connections in Yamaha s high-performance motorcycles, ATVs, and off-road equipment. Crafted from high-grade **spring steel**, this lock washer features a **tooth profile** that digs into the mating surfaces of bolts and nuts, preventing loosening caused by dynamic forces, heat, and repeated mechanical stress common challenges in demanding applications like suspension components, engine mounts, and steering systems. Its **self-locking design** eliminates the need for additional locking agents or adhesives, reducing maintenance hassles while maintaining reliability under extreme conditions. The washer s **consistent thickness and uniform tooth distribution** provide optimal clamping force distribution, minimizing wear on threaded fasteners and ensuring long-term durability. Ideal for professional mechanics and DIY enthusiasts alike, this washer is a critical component for maintaining the structural integrity and performance of Yamaha s off-road and sport bikes, where precision and reliability are non-negotiable. Its compatibility with standard bolts and nuts makes it a straightforward yet indispensable upgrade for any repair or assembly project requiring a dependable locking solution.

**Pros and Cons of buying a Yamaha 90215-10006-00 Lock Washer (No-Spin)**

### **Pros:**

The Yamaha 90215-10006-00 is a **lock washer**, specifically designed for the **Yamaha FZ-150/FZS1** (or similar models) to prevent the nut from loosening over time. Here are the key advantages:

1. **Prevents Nut Loosening** The washer s serrated or toothed design grips the metal surface, reducing vibration-induced loosening of critical fasteners like the rear axle nut or suspension components.

2. **Durable Construction** Made from high-quality steel, it is designed to withstand repeated tightening and loosening without deforming or wearing out prematurely.

3. **Easy Installation** Simple to install just place it between the nut and bolt before tightening. No special tools are required beyond a wrench or socket.

4. **Cost-Effective Solution** Compared to replacing a damaged axle or suspension component due to a loose nut, this washer is a **low-cost preventive measure** that extends the life of your bike s fasteners.

5. **OEM Quality (If Authentic)** If purchased from Yamaha or an authorized dealer, it meets the same standards as the original equipment, ensuring compatibility and reliability.

6. **Minimal Maintenance** Once installed correctly, it requires no further attention unless the bike undergoes heavy use or off-road conditions where fasteners are more prone to loosening.

### **Cons:** While the lock washer is a useful part, there are some potential drawbacks to consider:

1. **Not a Permanent Fix for Poor Installation** If the nut was improperly tightened initially (e.g., not torqued to spec), the lock washer may not prevent loosening. Always follow the manufacturer s torque specifications.

2. **Can Become Stiff or Seized** Over time, especially in high-vibration environments (e.g., off-roading), the washer s teeth may bind, making removal difficult. This can be problematic if you need to service the component later.

3. **Limited Use in Corrosive Environments** If the bike is exposed to salt, moisture, or extreme weather, the washer (like all steel parts) can rust. A **thread locker (Loctite) or corrosion-resistant coating** may be needed for added protection.

4. **Not a Substitute for Proper Fastening Techniques** Some riders mistakenly rely solely on lock washers without using **thread locker or proper torque values**, which can still lead to failure if the washer is not the primary locking mechanism.

5. **Potential for Over-Tightening Damage** If excessive force is applied when tightening, the washer s teeth may shear or the bolt/nut threads could strip. Always use a torque wrench when possible.

6. **Availability and Authenticity Risks** If purchasing from a third-party seller (e.g., eBay, Amazon), there is a chance of receiving a **counterfeit or low-quality replica**, which may not perform as well as the genuine Yamaha part.

### **Conclusion:**

The **Yamaha 90215-10006-00 lock washer** is a **practical and affordable** solution for preventing nut loosening in critical bike components. It is particularly useful for riders who frequently ride on rough terrain or in high-vibration conditions. However, it is not a standalone fix proper installation (correct torque, thread locker if needed) is essential for maximum effectiveness.

For most riders, this washer is a **worthwhile investment** to extend the life of fasteners and avoid costly repairs. If you plan to use it in extreme conditions, consider supplementing it with **Loctite Blue (medium-hold) or Red (permanent)** for added security.

### **Recommendation:**

- **Buy from an authorized Yamaha dealer or a trusted online retailer** (e.g., Yamaha s official site, reputable motorcycle parts stores) to ensure authenticity.

- **Use it in conjunction with thread locker** (Loctite) for better reliability, especially on high-stress components like the rear axle nut.

- **Follow the manufacturer s torque specifications** when tightening to avoid overloading the washer or damaging threads.

- **Inspect the washer periodically** during maintenance to ensure it is still functional and not corroded or deformed.

If you are unsure about installation, consult a **mechanic** to ensure proper application. For most riders, this part is a **simple but valuable addition** to their bike s maintenance routine.
