The installation method of the Toyota clutch kit varies slightly by model, but the overall steps are roughly the same. The general installation method is as follows:
Insert the special tool (SST: 09301-00230) into the clutch disc assembly, then insert them together into the flywheel assembly. Ensure the lining part of the clutch disc assembly, the pressure plate, and the surface of the flywheel assembly are free from oil and foreign objects, and insert the clutch disc assembly correctly in the right direction.
Align the matching marks on the clutch pressure plate assembly with those on the flywheel assembly.
Following the illustrated steps, start with the bolt at the top near the locating pin and tighten the 6 bolts in sequence. The tightening torque is 19.1N·m (195kgf·cm, 14ft·lb). Tighten one bolt evenly at a time in the illustrated order. After checking that the clutch disc assembly is centered, move the special tool gently up, down, left, and right, then tighten the bolts.
Use a dial indicator with a roller tool to check the alignment of the diaphragm spring tips. The maximum misalignment is 0.5mm (0.0197in.).
If the alignment does not meet the specifications, use a special tool (SST: 09333-00013) to adjust the alignment of the diaphragm spring tips.
Temporarily tighten the clutch release cylinder to bleed pipe onto the new clutch release cylinder with bearing assembly. Ensure no foreign objects (such as dust or dirt) enter the clutch release cylinder to bleed pipe from the connection part.
Clean and degrease all installation surfaces of the clutch release cylinder with bearing assembly.
Install the clutch release cylinder with bearing assembly using 3 new bolts. The tightening torque is 22.5N·m (229kgf·cm, 17ft·lb). Note that the clutch release cylinder with bearing assembly and installation bolts cannot be reused and must be replaced with new ones. During installation, clean and degrease all installation surfaces, and ensure the clutch release cylinder with bearing assembly is firmly fitted with the manual transmission assembly. The first bolt should be hand-tightened while holding the clutch release cylinder with bearing assembly.
In addition, disconnect the negative battery cable before installation. Pay attention to the installation direction and cleanliness of each component during installation. After installation, perform corresponding inspections and tests to ensure the clutch works normally.
Core Conclusion: Installation must strictly follow Toyota's original factory specifications, focusing on component cleanliness, installation accuracy, and torque standards to avoid clutch abnormal noise, slipping, or incomplete disengagement, ensuring stable operation of the transmission system.
Disconnect the negative battery cable to prevent short circuits or false triggers of the electrical system during installation.
Confirm that the clutch kit model is fully compatible with the Toyota vehicle model (e.g., Corolla, Camry, Prado) and transmission type to avoid component incompatibility.
Thoroughly clean the surfaces of the flywheel, pressure plate, and clutch disc to remove oil, rust, and impurities. Oil can cause clutch slipping, and impurities may lead to wear or abnormal noise.
Check the flywheel end face runout, which must meet the original factory standard (generally not exceeding 0.2mm). If it exceeds the standard, the flywheel needs to be repaired or replaced; otherwise, it will cause clutch jitter.
Ensure the clutch disc is installed in the correct direction, with the side with damping springs facing the transmission. Reversed installation will result in clutch disengagement failure.
The matching marks on the pressure plate and flywheel must be aligned to ensure uniform force distribution and prevent pressure plate deformation.
Tighten the pressure plate fixing bolts in batches and evenly according to the original factory-specified sequence (usually cross-symmetrical), strictly following the torque standard (generally 19-25N·m, refer to the vehicle manual for details). Avoid one-time tightening or insufficient/excessive torque.
Use a special guide tool to position the clutch disc during installation to ensure concentricity with the flywheel and pressure plate. Otherwise, it will cause difficulty in installing the transmission input shaft or abnormal clutch operation.
Apply special grease to the release bearing to avoid dry friction damage, and ensure the bearing is flexible without jamming.
The release cylinder with bearing assembly and installation bolts must be replaced with new ones and cannot be reused. Otherwise, it will lead to seal failure or loose installation.
The installation surface of the release cylinder must be cleaned and degreased. After installation, ensure a firm fit with the transmission to avoid excessive clearance causing incomplete disengagement.
When connecting the release cylinder pipeline, prevent foreign objects from entering the pipeline to avoid blockage or oil leakage due to poor sealing.
After installation, check the alignment of the diaphragm spring tips. The maximum misalignment should not exceed 0.5mm. If it exceeds the standard, use a special tool to adjust; otherwise, it will cause uneven force on the clutch pedal or incomplete disengagement.
After installation, manually push the clutch pedal to check if the disengagement stroke is normal, with no jamming or poor return.
Bleeding process: Bleed the hydraulic clutch system to remove air from the pipeline. Otherwise, it will cause a soft pedal and incomplete disengagement.
After starting the vehicle, lightly step on the clutch pedal at idle speed to feel if the disengagement is smooth without abnormal noise.
Test the clutch engagement point: Slowly lift the pedal to confirm a clear engagement point, with no slipping (engine speed increases but vehicle speed does not match) or jitter.
Road test inspection: Test the clutch performance during gear shifting at different speeds to ensure smooth shifting, with no difficulty in engaging gears, gear slipping, or abnormal noise.
Do not apply ordinary grease to the surfaces of the clutch disc, pressure plate, or flywheel. Only the release bearing can use special high-temperature grease.
Avoid tool collisions with the pressure plate diaphragm spring during installation to prevent spring deformation or breakage.
If components such as the clutch release fork and push rod are replaced during disassembly, adjust the pedal free travel to the original factory standard (generally 5-15mm) to ensure complete disengagement.
Avoid heavy-load starting and frequent half-engagement in the short term after installation to allow running-in time for the clutch components (gentle driving is recommended within the first 1000 kilometers).

However, based on the content related to the "Key Precautions for Installation of Toyota Clutch Kit" you mentioned earlier and combined with the search results, it may come from the following places:
For example, yotashop.com in Summary 2, whose published "Clutch Installation Guidelines" mentions precautions such as following the steps in the maintenance manual, paying attention to the direction of the clutch disc, and cleaning the installation area when installing the clutch.
PCauto in Summaries 5 and 6, whose articles on the replacement of the Toyota Corolla clutch three-piece set and key points for clutch replacement also involve precautions during the clutch installation process.
The original maintenance manual of Toyota vehicles will detailedly explain the installation method and precautions of the clutch kit. The mention in the text of operating in accordance with the vehicle manufacturer's guide manual actually refers to referring to the maintenance manual. However, the specific content of the maintenance manual is not directly displayed in the current search results.
For example, Original Power Document in Summary 3, whose "Disassembly, Assembly and Adjustment of Automobile Chassis" mentions some precautions during clutch assembly, such as the installation direction of the driven disc and the tightening torque of bolts.
