General Installation Method for Clutch Discs of Toyota/Daihatsu Models

This method is applicable to the installation of dry clutch discs for most manual-transmission Toyota and Daihatsu models. The core requirements are aligning the positioning pins, ensuring correct orientation, and uniformly tightening the pressure plate bolts. The specific steps are as follows:

I. Pre-installation Preparation

1. Cleaning Components

Thoroughly clean the flywheel surface, pressure plate mounting surface and transmission input shaft splines to remove oil stains, rust and metal debris. Oil contamination can cause clutch slippage, while impurities may lead to incomplete disengagement.

Wipe the surfaces with a clean cloth dipped in anhydrous ethanol or a dedicated cleaner. Do not allow oil-based lubricants to come into contact with the friction surfaces.

2. Inspecting Component Condition

Confirm that the friction surface of the clutch disc is free of cracks, burn marks and exposed rivets; ensure the splined bore fits smoothly with the input shaft splines without jamming.

Check that the diaphragm spring of the pressure plate has uniform elasticity, and the end face runout of the flywheel complies with the original factory standard (generally not exceeding 0.2mm).

Prepare a dedicated clutch centering tool (a transmission input shaft can be used as an alternative if unavailable) to fix the position of the clutch disc.

3. Distinguishing Component Orientation

Clutch discs for Toyota/Daihatsu models are usually marked with orientation indicators: the side labeled "FLYWHEEL SIDE" or "TRANSMISSION SIDE" shall face the corresponding mounting surface as indicated.

If there is no orientation marking, the side with protruding damping springs should generally face the transmission, and the side with the thicker friction lining should face the flywheel.

II. Specific Installation Steps

1. Positioning the Clutch Disc

Slide the clutch disc onto the positioning pin at the center of the flywheel, then insert the dedicated centering tool to ensure the clutch disc is fully concentric with the flywheel (the centering tool must be inserted into both the splined bore of the clutch disc and the pilot bearing of the flywheel).

After confirming the correct orientation, place the pressure plate over the clutch disc and align the pressure plate bolt holes with those on the flywheel.

2. Tightening the Pressure Plate Bolts

Adopt the cross-symmetric tightening method (e.g., tighten in the sequence of 1-3-5 clockwise and 2-4-6 counterclockwise), and gradually tighten the bolts in 2–3 passes to avoid pressure plate deformation.

Tighten the bolts strictly in accordance with the original factory torque specification. For most Toyota/Daihatsu models, the torque for pressure plate bolts is 18–25 N·m. Refer to the maintenance manual of the specific model for exact values.

3. Removing the Centering Tool

After the bolts are fully tightened, slowly pull out the centering tool and check that the clutch disc is free of displacement or loosening.

4. Installing the Transmission Assembly

When lifting and installing the transmission, ensure the input shaft is smoothly inserted into the splined bore of the clutch disc. Avoid forced impact, which may cause displacement of the clutch disc or damage to the splines.

Install components such as the clutch release bearing and release fork, and adjust the release fork stroke to meet the original factory requirements to ensure uniform release clearance.

Key Precautions for Clutch Disc Installation of Toyota/Daihatsu Models

Strictly Prohibit Reverse Installation
The side marked "FLYWHEEL SIDE" must face the flywheel, and the side marked "TRANSMISSION SIDE" must face the transmission. If there is no marking, the side with protruding damping springs should face the transmission, and the side with thicker friction linings should face the flywheel.

Reverse installation will directly cause incomplete clutch disengagement and gear shifting jamming. In severe cases, it will burn the clutch disc and damage the diaphragm spring of the pressure plate.

Friction Surfaces Must Be Kept Free of Oil Contamination
Before installation, thoroughly clean oil stains and iron filings off the friction surfaces of the flywheel, pressure plate and clutch disc with anhydrous ethanol or a dedicated cleaner. During installation, do not touch the friction surfaces with gloves contaminated by engine oil.

Oil contamination will lead to clutch slippage and vehicle shaking during starting. Even a trace amount of oil can affect the working performance of the clutch.

Bolt Tightening Must Follow Cross-Symmetric and Stepwise Force Application
Tighten the pressure plate bolts in a cross-symmetric sequence (e.g., 1-3-5-2-4-6) in 2–3 passes. The final torque must strictly comply with the original factory specifications (18–25 N·m for most models).

Single-pass tightening or asymmetric fastening will cause deformation of the pressure plate, leading to faults such as uneven clutch release clearance and abnormal noise.

Lubrication Is Restricted to Specific Parts Only
Only a small amount of high-temperature grease is allowed to be applied to the splines of the transmission input shaft, the guide sleeve of the release bearing, and the fulcrum of the release fork. Under no circumstances should any lubricant be applied to the clutch friction surfaces, pressure plate surfaces, or flywheel end faces.

Incorrect lubrication will directly result in clutch slippage and failure.

It Is Recommended to Replace Components as a Complete Set
Replace the clutch disc, pressure plate and release bearing simultaneously to avoid uneven engagement, abnormal noise and shortened service life caused by mismatched wear levels between new and old components.

Check the flywheel end face runout at the same time; if it exceeds 0.2mm, the flywheel must be repaired by turning or replaced entirely.

Centering Tool Is Indispensable
Use a dedicated clutch centering tool during installation (a transmission input shaft can be used as an alternative if the tool is unavailable) to ensure the clutch disc is fully concentric with the flywheel.

Poor centering will make it impossible to install the transmission input shaft smoothly, or cause uneven wear and shaking of the clutch during operation.

1	Prohibition of reverse installation (distinction by markings / judgment without markings)	Toyota Original Factory Maintenance Manuals (e.g., for Yaris, Camry, etc.), Daihatsu 4WD Model Maintenance Manuals	The manuals clearly specify that the side marked "FLYWHEEL SIDE" shall face the flywheel, and the side with protruding damping springs shall face the transmission. Reverse installation will cause disengagement faults.
2	Strict prohibition of oil contamination on friction surfaces	CLUTCH Chapter of Toyota Maintenance Manuals, Technical Specification for Automobile Clutch System Maintenance (GB/T 5372-2019)	The original factory requires cleaning friction surfaces with anhydrous ethanol. The GB standard stipulates that oil contamination will cause slippage, and no lubricants shall come into contact with friction surfaces.
3	Cross-symmetric and stepwise tightening of pressure plate bolts	Toyota Crown/Corolla Maintenance Manuals, Daihatsu Clutch Maintenance Specifications	The manuals require tightening bolts in the sequence of 1-3-5-2-4-6 in 2–3 passes with a torque of 18–25 N·m to prevent pressure plate deformation.
4	Lubrication restricted to specific parts only	Toyota SST Tool Operation Instructions, Daihatsu Clutch Lubrication Specifications	Only a small amount of high-temperature grease may be applied to transmission input shaft splines and release bearing guide sleeves; lubrication on friction surfaces/pressure plate surfaces is prohibited.

The original factory recommends replacing the clutch disc, pressure plate and release bearing simultaneously.
6	Mandatory use of centering tools	Toyota SST Special Tool Manuals (e.g., 09301-00230), Daihatsu Clutch Installation Specifications	The manuals mandate the use of centering tools (or transmission input shafts as alternatives) to ensure concentricity between the clutch disc and flywheel, avoiding uneven wear.
7	Test run inspection after installation	Troubleshooting Chapter of Toyota/Daihatsu Model Maintenance Manuals	The manuals require test runs to check for vehicle shaking during starting, smoothness of gear shifting, and slippage during sudden acceleration, which serves as a verification process for installation issues.
8	Marking relative positions before disassembly	Toyota/Daihatsu Transmission Disassembly Specifications, General Operation Guidelines of the Automobile Maintenance Industry	Marking the relative positions of the flywheel and pressure plate and aligning them during reassembly reduces the risk of pressure plate deformation, which is a standard operation in original factory maintenance.

Supplementary Notes
