I. Preparation

1. Safety Confirmation: Ensure the vehicle is securely lifted or supported by stands, and the transmission has been removed.

2. Tool Preparation:

• Clutch Aligning Tool: Mandatory. Used to ensure the friction disc is concentric with the crankshaft.

• Torque wrench and socket set (12mm, 14mm, 17mm, 19mm, etc.).

• Locating Pins (if necessary): Used to secure the pressure plate.

• Grease: High-melting point grease, specifically for input shaft spline lubrication.

II. Critical Check: Confirm Installation Direction (Most Important Step)

1. Check Markings: The side of the friction disc is usually stamped with "FRONT" (Flywheel side) or "T/M SIDE" (Transmission side).

• The "FRONT" side should face the engine/flywheel.

• The "T/M SIDE" side should face the transmission.

2. Check Structure:

• If the disc has a spring damper (hub), the side with the longer hub usually faces the transmission (T/M side).

• If the disc is asymmetrical, the side with shallow or flat rivet heads faces the flywheel.

III. Installation Steps (Standard Procedure)

1. Lubricate Input Shaft Splines

• Apply a small amount of high-melting point grease into the spline grooves of the friction disc.

• Caution: Do not over-apply, and ensure grease does not contaminate the friction surfaces (the linings), as this will cause clutch slippage.

2. Install Flywheel (If Replaced)

• If a new flywheel is installed, tighten the flywheel bolts in a crisscross sequence in multiple passes to the specified torque (typically 60-80 N·m, depending on the model).

3. Install Clutch Disc and Pressure Plate

• Place Pressure Plate: Align the clutch cover/pressure plate with the locating dowels on the flywheel (or use dedicated locating pins).

• Insert Friction Disc: Place the friction disc between the pressure plate and the flywheel.

• Align: Insert the aligning tool through the friction disc splines and into the pilot bearing or center hole at the rear of the crankshaft.

• Adjust: Gently move the friction disc by hand to ensure the aligning tool rotates smoothly, indicating the disc is perfectly centered.

4. Tighten Pressure Plate Bolts

• Using a torque wrench, tighten the pressure plate mounting bolts in a diagonal/crisscross sequence (from inside to outside) in multiple passes.

• Standard Torque Reference: Typically between 15 N·m and 25 N·m for Nissan models (refer to the specific model's service manual for exact values).

• Key Point: Continuously rotate the aligning tool while tightening to ensure the friction disc has not shifted.

5. Remove Tool

• Once the bolts are fully tightened, remove the aligning tool.

IV. Post-Installation Inspection and Finalization

1. Inspect Release Bearing:

• Check that the release bearing rotates smoothly without binding or abnormal noise.

• Apply a small amount of grease to the contact point between the release fork and the bearing.

2. Install Transmission:

• Thanks to the use of the aligning tool, the transmission input shaft should slide smoothly into the friction disc splines.

• If pushing it in is difficult, strictly prohibit using brute force or hammering. Re-dismantle and check if the disc is misaligned or installed backwards.

3. Secure Transmission:

• Tighten the engine-to-transmission mounting bolts to the specified torque.

I. Orientation Confirmation (A Critical Step)

• Action: Must repeatedly confirm the front and back sides of the friction disc before installation.

• Common Nissan Markings:

• "FRONT" or "FLYWHEEL SIDE": Faces the engine/flywheel.

• "T/M SIDE" or "TRANSMISSION": Faces the transmission.

• "Spring on one side only": Usually, the protruding side with springs (damper) faces the transmission (T/M side).

• Consequence: If installed backwards, the transmission input shaft will bottom out against the crankshaft, preventing the transmission from being installed. Even if it can be installed, the clutch will not disengage fully, causing gear grinding (crashing gears) and making the vehicle undrivable.

II. Cleaning and Oil Prevention (Core Lifespan Factors)

• Action: Both sides of the friction disc (the friction material surfaces) must be kept absolutely dry and clean.

• Taboos: Greasy hands, oil mist from compressed air dust blowers, or dripping grease.

• Consequence: Even a single drop of oil will cause clutch slippage, glazing, and a burning smell. This damage cannot be repaired by sanding; the part must be replaced.

• Action: Inspect the contact surfaces of the flywheel and pressure plate before installation.

• Standard: Surfaces should be flat, smooth, and free of obvious grooves, glazing spots, or cracks.

• Treatment: Minor scratches can be polished with fine sandpaper. If deep grooves or heat cracks exist, the flywheel must be replaced; otherwise, the new disc will wear quickly or cause judder during take-off.

III. Lubrication and Spline Treatment (Anti-seizure)

• Action: Apply high-melting point grease (usually included with the clutch kit) inside the friction disc hub splines.

• Caution: Apply only to the splines and use a moderate amount (a thin layer).

• Consequence: No lubrication will cause spline wear and incomplete clutch disengagement (binding). Too much lubrication will fling off onto the friction surfaces, causing slippage.

• Action: Check that the release bearing rotates freely. Apply grease to the contact point between the release bearing and the fork, as well as the pivot point of the fork shaft.

• Note: For some Nissan models (e.g., Sylphy, X-Trail), the release bearing is maintenance-free and cannot be disassembled for cleaning. If there is abnormal noise, replace it directly.
