In this tutorial, we will guide you through the process of replacing a flywheel on a 2007 Honda Fit. This step-by-step guide is designed to help both novice and experienced DIY mechanics understand the steps involved in removing an old flywheel and installing a new or resurfaced one. Proper flywheel installation is crucial for the engine's performance, so follow these instructions carefully.

Step 1: Gather Your Tools and Materials

Before starting, make sure you have all necessary tools and materials on hand:

• Tools:

  • Socket set
  • Torque wrench
  • Flywheel locking tool (if needed)
  • Screwdrivers
  • Pliers
  • Hammer
  • Clean rag

• Materials:

  • New or resurfaced flywheel
  • Flywheel bolts (if necessary)
  • Engine oil or grease (for lubrication)

Step 2: Disconnect the Battery

Safety first! Follow these steps to disconnect the battery:

1. Open the hood of your Honda Fit.
2. Locate the battery and identify the negative terminal (usually marked with a minus sign).
3. Use a wrench to loosen the bolt on the negative terminal and remove the cable.
4. Secure the cable away from the battery to prevent accidental reconnection.

Step 3: Remove the Transmission

To access the flywheel, you will need to remove the transmission:

1. Lift the Vehicle: Use a jack to raise the car and secure it with jack stands.
2. Remove Underbody Components: Take off any components obstructing access to the transmission, such as the belly pan.
3. Disconnect Linkages: Detach the gear shift linkage and any electrical connections.
4. Unbolt the Transmission: Remove the bolts securing the transmission to the engine. Keep track of the bolt sizes and locations.
5. Lower the Transmission: Carefully lower the transmission and set it aside.

Step 4: Remove the Old Flywheel

Access the old flywheel by following these steps:

1. Locate the Flywheel: The flywheel is mounted on the crankshaft at the rear of the engine.
2. Support the Flywheel: Use a flywheel locking tool or a screwdriver to prevent it from rotating.
3. Remove Flywheel Bolts: Using a socket set, remove the bolts securing the flywheel to the crankshaft. Ensure you keep the bolts in a safe place.
4. Take Off the Flywheel: Gently pull the old flywheel off the crankshaft.

Step 5: Prepare for Installation

Before installing the new flywheel, take these preparatory steps:

1. Clean the Surface: Use a clean rag to wipe down the crankshaft and remove any debris or old gasket material.
2. Inspect the Crankshaft: Look for any signs of wear or damage. If damage is present, consult a professional.

Step 6: Install the New Flywheel

Follow these steps to install the new flywheel:

1. Position the Flywheel: Align the new or resurfaced flywheel with the crankshaft.
2. Secure the Flywheel: Hand-tighten the flywheel bolts in a crisscross pattern to ensure even pressure.
3. Torque the Bolts: Use a torque wrench to tighten the bolts to the manufacturer’s specifications. Refer to your vehicle’s service manual for the correct torque specifications.

Step 7: Reassemble the Transmission

Once the flywheel is installed, reassemble the transmission:

1. Lift the Transmission: Carefully lift the transmission back into position.
2. Bolt the Transmission: Secure the transmission to the engine using the previously removed bolts.
3. Reconnect Linkages: Reattach the gear shift linkage and any electrical connections.
4. Replace Underbody Components: Reinstall any components removed earlier.

Step 8: Reconnect the Battery

Complete the process by reconnecting the battery:

1. Attach the Negative Terminal: Place the negative cable back onto the battery terminal and tighten the bolt.
2. Close the Hood: Ensure everything is secure, and close the hood of your Honda Fit.

Conclusion

Replacing a flywheel on your Honda Fit can improve engine performance and reliability. Make sure to follow each step carefully, use the right tools, and refer to your vehicle’s service manual for specific torque specifications. Once completed, take your car for a short test drive to ensure everything is functioning correctly. If you encounter any issues, consider consulting a professional mechanic. Happy wrenching!
