I. Pre-installation Preparation (Safety and Cleanliness are Fundamental)

Vehicle and Safety

Park the vehicle on level ground, apply the parking brake, disconnect the power supply and remove the negative battery terminal. Securely support the vehicle using a hoist or jack with safety stands; place a protective plate under the transmission to prevent falling.

Disconnect the clutch slave cylinder, release fork, and other connections; remove the transmission assembly and place it on a special support stand.

Tools and Materials

Required tools: Torque wrench (accuracy ±3%), clutch alignment tool, Phillips / socket wrench, flywheel holder, bearing puller (if the release bearing needs replacement).

Materials: New Dafu clutch pressure plate assembly, clutch disc, release bearing, high-purity grease (e.g., molybdenum-based / polyurea-based), anhydrous ethanol / acetone (for cleaning), new locating pins and bolts (single-use replacement recommended).

Component Inspection and Cleaning

Inspect the flywheel surface: no warpage (flatness ≤ 0.1 mm), no cracks, no severe grooves. Check with a dial indicator; re-machine or replace if out of tolerance.

Clean the friction surfaces of the flywheel, pressure plate, and clutch disc splines with anhydrous ethanol. Oil contamination is strictly prohibited (may cause slipping). Inspect the pressure plate diaphragm spring for no fractures and even wear on the release fingers.

Confirm the clutch disc orientation: the damper plate faces the pressure plate; the spline hub end fits smoothly with the input shaft without jamming.

II. Installation Procedures (Core Operations)

Positioning and Alignment

Place the clutch disc on the flywheel. Insert the alignment tool through the flywheel center bearing bore and the clutch disc spline hub to ensure concentricity.

Align the pressure plate with the flywheel locating pins, confirm the installation direction (usually marked “Flywheel Side”), and place it gently onto the clutch disc to avoid impact on friction surfaces.

Bolt Tightening (Critical)

Pre-tightening: Thread all bolts by hand to ensure smooth engagement and even contact between the pressure plate and flywheel.

Tighten crosswise and diagonally (example for 6 bolts: 1→4→2→5→3→6):

1st pass: 10–15 N·m (pre-tighten to eliminate clearance)
2nd pass: 25–30 N·m (gradually load)
3rd pass: Final tightening to Dafu specification (typically 35–45 N·m, refer to product manual for exact value) using a calibrated torque wrench.

Direct tightening with a pneumatic impact wrench is prohibited to prevent pressure plate deformation.

Release Bearing and Fork Installation

Apply a small amount of grease to the inner race of the release bearing, then install it into the release fork. Ensure the bearing slides freely along the guide sleeve without jamming.

Adjust the release clearance: 2–3 mm between the release finger ends and the bearing face (varies by vehicle model). Calibrate using the master cylinder push rod or fork adjusting screw.

Transmission Reinstallation

Use the alignment tool to guide the input shaft into the clutch disc splines to avoid damage. Install the transmission slowly and ensure the input shaft bearing seat aligns with the flywheel housing locating bore.

Tighten the transmission mounting bolts to specified torque. Connect the clutch slave / master cylinder oil line and bleed air until no bubbles appear.

III. Post-installation Adjustment and Verification

Mechanical Inspection

Rotate the input shaft; no abnormal friction noise between the pressure plate and clutch disc. Clutch pedal free travel meets vehicle specification (typically 15–25 mm).

Start the engine. At idle, depress the pedal to confirm complete disengagement (no drag); release to confirm smooth engagement without shuddering.

Road Test Verification

Low-speed gear shifting: 1→2→3 gears smooth, no gear grinding. No slipping during high-speed acceleration (engine RPM rises without corresponding vehicle speed increase).

Hill-climbing and load test: Stable semi-linkage condition, no abnormal odor (overheating of friction disc). Confirm qualified installation.

I. Mandatory Pre‑Installation Checks

Strictly No Oil ContaminationThe friction surfaces of the flywheel, pressure plate, and clutch disc must not come into contact with oil, grease, engine oil, or sweat. Any contamination will cause slipping and shuddering.
Inspect New and Old Components

Pressure plate diaphragm spring: no deformation, cracks, or ablation.
Clutch disc: no cracks, rivets not exposed.
Flywheel: flat surface, no deep grooves or deformation.

Do Not Install the Clutch Disc Backwards
The side with the damper plate / large hub must face the transmission / pressure plate. Reversed installation will result in poor disengagement and gear grinding.

II. Key Points During Installation

Alignment Tool Is MandatoryWithout a centering shaft, the transmission will be difficult to install and may damage the input shaft bearing.
Tighten Bolts Diagonally and In Stages

Thread all bolts by hand first.
Tighten evenly diagonally in 2–3 passes.
Direct tightening with an impact wrench is strictly prohibited, as it will deform the pressure plate.

Standard Torque RequiredGeneral clutch pressure plate bolt torque: 25–45 N·m (refer to the Dafu manual / vehicle service manual for exact values).
Check the Release Bearing At the Same TimeReplace it immediately if there is abnormal noise, sticking, or excessive play.

III. Mandatory Checks After Installation

After installing the transmission, rotate the clutch housing manually; it should turn smoothly without binding.
The clutch pedal must have free play; it must not constantly press against the release bearing.

Test Run Inspection:

Smooth start without shuddering.
Smooth gear shifting without grinding.
No slipping during acceleration (slippage occurs when engine RPM rises sharply but vehicle speed does not).

IV. Prohibited Actions (Do NOT Do)

Do not strike the pressure plate or clutch disc with a hammer.
Do not force the transmission into position.
Do not reuse old bolts.
Do not drive the vehicle without adjusting pedal free play first.
