2. Product Features

• Optimized Design: Specifically developed for electric on-road RC cars, including EPR and F1 touring cars.
• 64-Pitch Gearing: Utilizes a 64-pitch standard for enhanced durability and smooth power transfer.
• High Precision Construction: Manufactured with high precision materials and resin density, similar to the TCS series, ensuring consistent performance.
• Ultra-Lightweight: Designed for minimal weight, contributing to improved vehicle dynamics. For example, a 94-tooth gear weighs approximately 2.5 grams (0.1 oz).
• Low Friction: Engineered to minimize friction, promoting efficient power delivery and smooth operation.
• Enhanced Acceleration & Top Speed: Contributes to superior acceleration and high top speeds, particularly beneficial in stock racing categories.
• Optimized Ball Differential Compatibility: Features an optimized design for ball differentials, ensuring smooth engagement and consistent performance with 12 differential balls.

3. Setup and Installation

Proper installation of the spur gear is crucial for the performance and longevity of your RC vehicle. Always refer to your specific RC car's chassis manual for detailed instructions regarding gear replacement and driveline assembly.

1. Disassembly: Carefully remove the existing spur gear and any associated components (e.g., motor, motor mount, differential assembly) from your RC car chassis as per your vehicle's manual.
2. Inspection: Inspect the motor pinion gear and differential components for any wear or damage. Replace any worn parts to ensure optimal performance with the new spur gear.
3. Mounting the Spur Gear: Mount the Axon Spur Gear DTS 64P 88T GS-D6-088 onto the differential or main shaft according to your chassis design. Ensure it is securely fastened and centered.
4. Setting Gear Mesh: This is a critical step. The gear mesh is the clearance between the teeth of the spur gear and the motor pinion gear.
   • Loosen the motor mount screws slightly.
   • Push the motor towards the spur gear until the pinion and spur gear teeth are fully engaged without binding.
   • Insert a thin piece of paper (e.g., printer paper) between the teeth of the spur and pinion gears.
   • Push the motor against the spur gear, then rotate the spur gear to pull the paper through.
   • Adjust the motor position until the paper passes through with slight resistance, creating a small amount of play (backlash) between the gears. This ensures the gears do not bind and allows for smooth operation.
   • Tighten the motor mount screws securely, ensuring the gear mesh remains consistent.
5. Reassembly: Reassemble any other components removed during disassembly.
6. Final Check: Manually rotate the wheels and driveline to ensure smooth, free movement without any binding or excessive noise.

4. Operation

The Axon Spur Gear DTS 64P 88T GS-D6-088 functions as a key component in your RC car's driveline, transferring power from the motor pinion gear to the differential or main transmission. Its precise design ensures efficient power delivery, contributing to the vehicle's overall acceleration and top speed capabilities.

Once installed with the correct gear mesh, the spur gear will rotate smoothly, transmitting the motor's rotational force to the wheels. The 64-pitch design is optimized for a balance of strength and fine-tuning capabilities, allowing for precise gear ratio adjustments to suit different track conditions and motor characteristics.

5. Maintenance

Regular maintenance of your spur gear will extend its lifespan and maintain optimal performance.

• Inspection: Periodically inspect the spur gear for signs of wear, such as chipped teeth, rounding, or excessive play. Also check the motor pinion gear for similar wear.
• Cleaning: After each use, especially in dusty or dirty conditions, clean the spur gear and surrounding driveline components. Use a soft brush or compressed air to remove dirt, debris, and small stones that can cause premature wear.
• Gear Mesh Check: Regularly verify that the gear mesh between the spur gear and pinion gear is still correctly set. Vibrations and impacts can sometimes cause the motor mount to shift, altering the mesh.
• Lubrication (Optional): While plastic spur gears generally do not require lubrication, some users may apply a very light, dry lubricant designed for RC gears to reduce friction and noise. Consult your RC car's manual or experienced hobbyists for recommendations. Avoid excessive or wet lubricants, as they can attract dirt.
• Replacement: Replace the spur gear if significant wear or damage is observed. Continuing to use a worn gear can lead to damage to other driveline components, including the motor pinion and differential.

6. Troubleshooting

If you encounter issues with your spur gear, consider the following common problems and solutions:

• Excessive Noise or Grinding:
  • Cause: Incorrect gear mesh (too tight or too loose), debris lodged in gears, or worn gears.
  • Solution: Re-adjust gear mesh (refer to Section 3). Clean gears thoroughly. Inspect for wear and replace if necessary.
• Stripped or Damaged Teeth:
  • Cause: Incorrect gear mesh (too loose), impacts, motor mount shifting, or excessive power.
  • Solution: Replace the spur gear and potentially the pinion gear. Ensure correct gear mesh during installation. Check motor mount for security.
• Vehicle Lacks Power or Acceleration:
  • Cause: Slipping spur gear (if it's a slipper clutch type, though this is a direct drive spur gear), incorrect gear mesh, or other driveline issues.
  • Solution: Verify gear mesh. Inspect for any binding in the driveline. Ensure the spur gear is securely mounted.
• Spur Gear Wobbles:
  • Cause: Improper mounting, bent shaft, or manufacturing defect.
  • Solution: Re-mount the spur gear carefully, ensuring it's centered and tightened correctly. Inspect the shaft for straightness. If wobble persists, the gear may be defective and require replacement.
