🔩 Properties:

• Material: Typically made from high-grade billet aluminum or hardened steel depending on the intended stress level and brand.

• Precision Machined: CNC-machined for exact fitment to Yamaha Banshee 350 clutch covers.

• Corrosion Resistant: Anodized or treated for enhanced protection against rust, wear, and heat.

• Thread Strength: High-tolerance threading ensures a strong and secure grip on the lock-up components.

• Lightweight & Strong: Offers excellent strength-to-weight ratio—important in race applications where performance matters.

🏭 Manufacturing Process:

1. Material Selection:

   • Starts with premium billet aluminum blocks or high-tensile steel rods, selected for durability and thermal stability.

2. CNC Machining:

   • The screws are precision-machined using CNC lathes and mills, which cut the material to exact specifications.

   • This process ensures the screw dimensions, threading, and head shape are uniform and accurate.

3. Thread Forming:

   • Internal or external threading is cut or rolled into the screws with high-precision tools for a perfect match to the clutch cover threads.

4. Heat Treatment (if steel):

   • For steel variants, the screws may be heat-treated to increase hardness and tensile strength, making them more resistant to fatigue.

5. Surface Finishing:

   • The finished screws are anodized (for aluminum) or zinc-coated/polished (for steel) for corrosion resistance and a sleek appearance.

6. Quality Control:

   • Each screw is inspected for tolerance, thread integrity, and finish before packaging.

🛠️ How to Use:

Step-by-Step Installation Guide

1. Preparation:

   • Ensure your Yamaha Banshee is off and cooled down.

   • Place the quad on a stable lift or stand to access the clutch area easily.

   • Gather the proper tools: Allen keys, torque wrench, thread locker, and a clean cloth.

2. Remove the Existing Clutch Cover:

   • Use the appropriate socket or Allen wrench to remove the bolts securing your current clutch cover.

   • Carefully take off the cover to access the lock-up clutch fingers.

3. Inspect and Clean:

   • Check the lock-up clutch fingers and mounting area for debris, damage, or wear.

   • Clean the mounting area with a lint-free cloth to ensure a secure fit for the new screws.

4. Install the Finger Screws:

   • Align each lock-out finger with its designated mounting hole on the lock-up clutch.

   • Insert the billet finger screws into each finger’s mounting hole.

   • Optionally, apply a drop of medium-strength thread locker (like Loctite Blue) to the threads for added security.

5. Tighten Properly:

   • Use a torque wrench to tighten each screw evenly.

   • Recommended torque spec varies by manufacturer—typically 6–8 ft-lbs. Always refer to your clutch system’s manual for exact torque specs.

6. Reinstall the Clutch Cover:

   • Once the finger screws are secure, reinstall the clutch cover.

   • Tighten all bolts in a cross-pattern for even pressure distribution.

7. Test Functionality:

   • Slowly engage the clutch by hand or briefly start the quad to ensure smooth operation with no binding or abnormal noise.

✅ Pro Tips:

• Always use screws made from quality billet or steel to handle the high stress of lock-up clutch systems.

• Regularly inspect the screws during maintenance to ensure they remain secure.

• Avoid over-tightening to prevent stripping threads or damaging the billet parts.
