Introduction

This tutorial provides a step-by-step guide for replacing the clutch, flywheel, and slave cylinder on an Infiniti G37. This process can be extensive, so it’s split into two parts to cover all important details thoroughly. Whether you're a DIY enthusiast or a seasoned mechanic, this guide will help you navigate the disassembly phase of the project.

Step 1: Gather Necessary Tools and Materials

Before beginning the disassembly, ensure you have all required tools and materials:

• Socket set (including deep sockets)
• Wrenches (metric sizes)
• Torque wrench
• Screwdrivers (flathead and Phillips)
• Pliers
• Jack and jack stands
• Clutch replacement kit (including clutch, flywheel, and slave cylinder)
• Shop manual for your G37 (for reference)

Tip:

Organize your tools for quick access. A clutter-free workspace can significantly speed up the process.

Step 2: Prepare the Vehicle

Follow these steps to prepare your G37 for disassembly:

1. Safety First:

   • Park the vehicle on a level surface.
   • Engage the parking brake.
   • Disconnect the battery to prevent electrical issues.

2. Lift the Vehicle:

   • Use a jack to raise the front of the car.
   • Secure it with jack stands to ensure stability.

3. Remove Underbody Covers:

   • If applicable, remove any underbody panels that may obstruct access to the transmission.

Common Pitfall:

Failing to secure the vehicle properly can lead to serious injuries. Always double-check that jack stands are in place.

Step 3: Remove Transmission Components

To access the clutch, you need to remove several components:

1. Disconnect the Driveshaft:

   • Unbolt the driveshaft from the transmission using the appropriate socket.
   • Carefully slide it out and set it aside.

2. Remove the Transmission Crossmember:

   • Unbolt the crossmember that supports the transmission.
   • Support the transmission with a jack if necessary.

3. Unplug Electrical Connectors:

   • Disconnect any electrical connectors attached to the transmission, noting their locations for reassembly.

4. Remove the Transmission:

   • Unbolt the transmission from the engine block, ensuring all bolts are accounted for.
   • Carefully lower the transmission and set it aside.

Tip:

Label bolts and connectors as you remove them to simplify reassembly.

Step 4: Access the Clutch Assembly

With the transmission removed, you can access the clutch assembly:

1. Remove the Clutch Inspection Cover:

   • Unbolt and take off the inspection cover to expose the clutch.

2. Take Out the Clutch Fork:

   • Remove the clutch fork to gain better access to the clutch and flywheel.

3. Unbolt the Clutch Plate and Flywheel:

   • Carefully unbolt the clutch plate from the flywheel.
   • Remove the flywheel bolts, being cautious of any shims or spacers.

Common Pitfall:

Ensure you keep track of any washers and spacers. These are crucial for proper reassembly.
