BARNETT Clutch Friction Plate

1. Product Overview

The BARNETT Clutch Friction Plate (Model 301-90-10013) is a critical component designed for motorcycle clutch systems. This single replacement friction plate is engineered to provide reliable engagement and disengagement of power from the engine to the transmission, ensuring smooth operation and efficient power transfer.

This image displays a single, circular Barnett clutch friction plate. The plate features multiple segments of dark, textured friction material evenly spaced around its circumference, separated by lighter, metallic tabs. These tabs are designed to engage with the clutch basket.

2. Installation Guidelines

Proper installation of the friction plate is essential for clutch performance and longevity. It is highly recommended that installation be performed by a qualified motorcycle mechanic or an individual with extensive experience in clutch assembly.

2.1. Safety Precautions

• Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
• Ensure the motorcycle is stable and securely supported before beginning any work.
• Allow the engine and exhaust system to cool completely before handling components.
• Disconnect the battery to prevent accidental starting.

2.2. Pre-Installation Steps

1. Refer to Vehicle Service Manual: Always consult your specific motorcycle's service manual for detailed, model-specific instructions regarding clutch disassembly and reassembly.
2. Inspect Components: Before installing the new friction plate, thoroughly inspect all other clutch components, including steel plates, pressure plate, clutch basket, hub, and springs, for wear, damage, or warping. Replace any worn components.
3. Soak New Plates: It is crucial to soak new friction plates in the recommended engine oil for at least 30 minutes (or as specified by your motorcycle's service manual) prior to installation. This saturates the friction material, preventing premature wear and ensuring proper engagement.

2.3. Installation Procedure (General)

While specific steps vary by motorcycle model, the general procedure involves:

• Draining engine oil (if necessary for clutch cover removal).
• Removing the clutch cover.
• Removing clutch springs and pressure plate.
• Carefully removing old friction and steel plates, noting their order and orientation.
• Installing the new BARNETT friction plate along with existing or new steel plates in the correct sequence and orientation as per the service manual.
• Reinstalling the pressure plate and clutch springs, tightening fasteners to specified torque values.
• Reinstalling the clutch cover with a new gasket, refilling engine oil to the correct level.
• Adjusting clutch cable free play or hydraulic system as required.

3. Operating Considerations

Once the new friction plate is installed, proper clutch operation is key to its longevity and the overall performance of your motorcycle.

3.1. Break-in Period

A short break-in period is recommended for new clutch components. During this time, avoid aggressive acceleration, hard shifts, and excessive clutch slipping. This allows the friction material to properly seat and conform to the steel plates, optimizing performance and durability.

3.2. Proper Clutch Usage

• Avoid riding with the clutch partially engaged (slipping) for extended periods, as this generates excessive heat and accelerates wear.
• Ensure the clutch lever has the correct amount of free play to allow for full engagement and disengagement.
• Use the clutch smoothly and deliberately when shifting gears.

4. Maintenance

Regular inspection and maintenance of your motorcycle's clutch system will help ensure the longevity of your BARNETT friction plate and overall clutch performance.

• Regular Inspections: Periodically inspect clutch components for signs of wear, such as discoloration, glazing, or excessive thinning of friction material. Check steel plates for warping or bluing.
• Oil Quality: Use the manufacturer-recommended engine oil and change it at specified intervals. Contaminated or incorrect oil can negatively impact clutch performance and lifespan.
• Clutch Adjustment: Regularly check and adjust clutch cable free play or hydraulic system as per your motorcycle's service manual to ensure proper engagement and prevent slipping or dragging.
• Avoid Overheating: Minimize situations that cause clutch overheating, such as excessive slipping in heavy traffic or during off-road riding.

5. Troubleshooting

If you experience issues with your clutch after installing a new friction plate, consider the following common problems and potential causes:

• Clutch Slipping: The engine revs but the motorcycle does not accelerate proportionally. This can be caused by insufficient clutch free play, worn friction plates (even new ones if not properly soaked or if other components are worn), incorrect oil, or weak clutch springs.
• Clutch Dragging/Not Disengaging: The clutch does not fully disengage, making it difficult to shift gears or causing the motorcycle to creep forward when the clutch lever is pulled. Possible causes include excessive clutch free play, warped steel plates, incorrect plate stack height, or air in a hydraulic clutch system.
• Clutch Noise: Unusual noises (e.g., rattling, grinding) from the clutch area can indicate worn clutch basket fingers, loose components, or damaged bearings.

For persistent or complex issues, it is strongly recommended to seek diagnosis and repair from a professional motorcycle mechanic.
