Kit Contents:
- Nine (9) Friction Plates: These plates feature a carbon fiber material for improved grip and durability.
- Eight (8) Steel Drive Plates: Precision-machined steel plates that interact with the friction plates.
- Note: This kit is designed to eliminate the need for the stock riveted steel plate, which is often a point of failure in some original equipment clutch assemblies.
Setup and Installation
Proper installation is critical for the performance and longevity of your new clutch kit. Refer to your vehicle's specific service manual for detailed disassembly and reassembly procedures, as this guide provides general steps.
Required Tools and Materials:
- Vehicle-specific service manual
- Clutch spring compression tool
- Heavy-duty snap ring pliers
- Torque wrench
- New primary fluid (if applicable)
- Gaskets and seals (as required by vehicle manual)
Installation Steps:
- Preparation: Ensure the vehicle is on a stable, level surface. Disconnect the battery. Drain primary fluid if necessary, following your vehicle's service manual.
- Access Clutch: Remove the primary cover and any other components required to access the clutch assembly.
- Disassembly: Using a clutch spring compression tool, compress the clutch spring assembly. Carefully remove the retaining snap ring with heavy-duty snap ring pliers. Decompress the springs and remove the pressure plate, clutch springs, and the original clutch pack.
- Remove Stock Spring Plate: If your original clutch assembly includes a riveted spring plate, remove and discard it. The Barnett Extra-Plate kit is designed to replace this component.
- Install New Plates: Install the Barnett friction and steel plates into the clutch hub, alternating them according to your vehicle's service manual and Barnett's specific instructions (typically starting and ending with a friction plate). Ensure plates are properly seated.
- Reassemble Clutch: Reinstall the pressure plate, clutch springs, and spring compression tool. Compress the springs and carefully reinstall the retaining snap ring. Ensure the snap ring is fully seated in its groove.
- Final Assembly: Reinstall the primary cover with new gaskets and seals as needed. Refill primary fluid to the correct level.
- Clutch Adjustment: Adjust the clutch cable and lever free play according to your vehicle's service manual. Proper adjustment is crucial for correct clutch operation and to prevent premature wear.
Operating Instructions
After installation, the Barnett Extra-Plate Clutch Kit should provide a crisp and responsive engagement. A short break-in period may be beneficial, typically involving a few gentle engagements and disengagements to allow the new friction material to seat properly.
- Smooth Engagement: Engage and disengage the clutch smoothly. Avoid rapid or harsh engagements, especially during the initial break-in period.
- Proper Shifting: Ensure the clutch fully disengages when the lever is pulled to allow for smooth gear changes.
- Listen for Abnormalities: Pay attention to any unusual noises, slipping, or dragging sensations, which may indicate an issue requiring attention.
Maintenance
Regular maintenance helps prolong the life of your clutch kit and ensures consistent performance.
- Clutch Adjustment: Periodically check and adjust clutch cable free play as specified in your vehicle's service manual. Incorrect adjustment can lead to premature wear or clutch drag.
- Primary Fluid: If applicable, ensure your primary fluid is at the correct level and changed according to your vehicle's maintenance schedule. Use the recommended type of fluid.
- Inspection: During routine maintenance, inspect the clutch components for signs of wear, such as discoloration, warping, or excessive grooving on the plates.
Troubleshooting
This section addresses common issues you might encounter with your clutch and potential solutions.
