2. Safety Information

Always prioritize safety when working on automotive components. Failure to follow safety guidelines can result in serious injury or damage to the vehicle.

• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
• Ensure the vehicle is securely supported on jack stands or a lift before beginning any work.
• Disconnect the battery to prevent accidental starting or electrical shorts.
• Refer to your vehicle's service manual for specific torque specifications and procedures not covered here.
• Keep all tools and components organized to prevent loss or damage.

3. Package Contents

Verify that all components are present and undamaged before proceeding with installation.

• ARP Flexplate Bolts (Quantity as required for application)
• ARP Ultra-Torque Fastener Assembly Lubricant (Part #100-9908)

4. Installation Instructions

This section outlines the general procedure for installing the ARP Flexplate Bolt Kit. Specific steps may vary based on vehicle model and existing components. Always consult your vehicle's service manual for detailed removal and reinstallation procedures of the transmission and flexplate.

1. Preparation: Ensure the engine and transmission are properly supported and secured. Access to the flexplate area is critical. This typically involves removing the transmission.
2. Cleanliness: Thoroughly clean the threads in the crankshaft flange and on the new ARP flexplate bolts. Remove any old thread locker, oil, or debris.
3. Lubrication: Apply a small amount of the supplied ARP Ultra-Torque Fastener Assembly Lubricant to the threads of each ARP flexplate bolt and under the head of each bolt. This lubricant is crucial for achieving accurate torque readings and proper clamping force. Do not use other lubricants or thread lockers unless specifically instructed by ARP.
4. Flexplate Positioning: Position the flexplate onto the crankshaft flange, ensuring proper alignment with the dowel pins (if present) and bolt holes.
5. Initial Fastening: Install all ARP flexplate bolts finger-tight.
6. Torquing Procedure:
   • Using a calibrated torque wrench, tighten the bolts in a crisscross or star pattern.
   • Apply torque in several progressive steps (e.g., 30 ft-lbs, then 60 ft-lbs, then final torque).
   • Refer to the ARP specifications or your vehicle's service manual for the exact final torque value. For ARP flexplate bolts, a common torque range is 75-85 ft-lbs, but always confirm the specific requirement for your application.
   • Ensure each bolt reaches the specified torque.
7. Final Check: Double-check all bolts to ensure they are properly torqued.
8. Reassembly: Reinstall the transmission and any other components removed during the process, following your vehicle's service manual.

5. Operating

The ARP 102-2901 Flexplate Bolt Kit is a static component designed to securely fasten the flexplate to the crankshaft. Once properly installed and torqued, these bolts do not require active operation. Their function is to maintain a secure connection under all engine operating conditions.

6. Maintenance

Proper installation minimizes the need for ongoing maintenance. However, periodic inspection is recommended, especially during other transmission or engine work.

• Visual Inspection: During any service that provides access to the flexplate, visually inspect the bolts for any signs of loosening, damage, or corrosion.
• Re-torquing: If there is any doubt about the integrity of the fastening, or if the bolts have been removed for service, always re-torque them to the manufacturer's specifications using the ARP Ultra-Torque lubricant.

7. Troubleshooting

If issues arise after installation, consider the following common points:

• Vibration or Noise: If unusual vibrations or noises occur from the flexplate area, immediately cease operation and inspect the flexplate and bolts. This could indicate improper torque, a damaged flexplate, or other related issues.
• Loose Bolts: Loose bolts are almost always a result of improper installation, incorrect torque, or failure to use the specified lubricant. Re-torqueing is critical.
• Stripped Threads: If threads are stripped during installation, do not attempt to reuse the bolt or the damaged thread. Consult a professional for repair or replacement of affected components.
