The installation method for the Citroën clutch kit is as follows: •  Preparation Work: Prepare tools such as a socket wrench and torque wrench, as well as the new clutch kit. Park the vehicle on a flat and safe surface, pull up the handbrake, and use a jack and safety stands to lift and stably support the vehicle, ensuring there is sufficient operating space.  •  Removal of Related Components: Disconnect the negative battery terminal to prevent short circuits during operation. Then remove various pipelines and wires connected to the gearbox, such as the shift cable and clutch oil pipe. Next, remove the bolts fixing the gearbox and separate the gearbox from the engine.Remove the old clutch kit: After the gearbox is removed, the clutch pressure plate and clutch disc can be seen. Use a socket wrench to remove the bolts on the pressure plate, take the pressure plate off the engine flywheel, and then remove the old clutch disc.  •  Cleaning and inspection: Thoroughly clean the flywheel, the mounting surface of the pressure plate, and the input shaft of the gearbox with a cleaning cloth to remove oil stains, iron filings, rust, and other impurities. At the same time, check whether the surface of the flywheel is flat and whether there are damages such as scratches, wear, or heat spots. If there are serious problems, the flywheel needs to be replaced; check whether the release bearing rotates flexibly and whether there is jamming or abnormal noise. If there is any abnormality, it should also be replaced.Install the new clutch disc: After ensuring that the surface of the engine flywheel is clean, place the new clutch disc smoothly on the flywheel. Pay attention to the installation direction of the clutch disc. Generally, the side with the boss faces the transmission, and the flat side without the boss faces the flywheel. Additionally, make sure that the splined hole of the clutch disc matches the splines of the transmission input shaft.Install the clutch pressure plate: Align the pressure plate with the mounting position on the flywheel, gradually tighten the pressure plate bolts in a diagonal sequence. When tightening, use a torque wrench and operate according to the specified torque to ensure the pressure plate is installed firmly and under uniform force.  •  Install the release bearing: Install the release bearing at the corresponding position on the transmission input shaft and ensure it can move smoothly. For some vehicle models, it may be necessary to apply an appropriate amount of grease to the contact area between the release bearing and the release fork.Installing the gearbox: Align the gearbox with the engine, slowly push the gearbox onto the engine so that the input shaft is correctly inserted into the splined hole of the clutch disc. Then install the bolts that secure the gearbox, tighten them to the specified torque, and finally connect all the various pipelines and wires.  •  Adjustment and testing: After installation, it is necessary to inspect and adjust the clutch pedal to ensure that its stroke and force meet the requirements. Start the engine, press and release the clutch pedal multiple times, check whether the clutch disengages and engages smoothly, and whether there are any jams, abnormal noises, etc. At the same time, perform a gear shifting test to feel whether the shifting process is smooth and whether the power transmission is normal.

There are many precautions for installing a Citroën clutch kit, which are detailed as follows:Precautions before installation • Component inspection: Carefully check each component of the new clutch kit to ensure there are no damages, deformations, or other issues. Check whether the friction material on the surface of the clutch disc is intact, with no excessive wear, burning, or cracks; the diaphragm spring of the pressure plate should have good elasticity, with no fractures or deformations; the release bearing should rotate flexibly, with no jamming, abnormal noise, or looseness. At the same time, check whether the surface of the flywheel is flat and whether there are damages such as scratches, wear, or heat spots. If there are any problems, they need to be replaced in a timely manner.Cleaning Work: Use a clean cloth or a special cleaning agent to thoroughly clean parts such as the flywheel, pressure plate mounting surface, and transmission input shaft. Remove impurities like oil stains, iron filings, and rust to prevent these foreign matters from affecting the installation accuracy and the normal operation of components. Pay special attention to cleaning the impurities in the spline groove of the input shaft to ensure that the spline hole of the clutch disc can be smoothly fitted over it.  •  Tool Preparation: Prepare special tools such as a clutch pressure plate compressor, a central positioning pin, and a torque wrench. Using special tools can ensure the accuracy of installation and the safety of components, avoiding damage to parts caused by improper tools.Precautions during installation •  Installation direction of the clutch disc: The clutch disc has a clear installation direction. Generally, the side with a boss faces the transmission, and the flat side without a boss faces the flywheel. Additionally, the splined hole of the clutch disc must match the splines of the transmission input shaft. If installed backwards, the clutch will not work properly, leading to problems such as slipping and incomplete disengagement.  •  Pressure plate installation: When installing the pressure plate, align it with the installation position on the flywheel. Tighten the pressure plate bolts step by step in a diagonal sequence, and use a torque wrench to tighten them to the specified torque. This ensures the pressure plate is securely installed with uniform force distribution, preventing deformation of the pressure plate and avoiding negative impacts on clutch performance.Installation of the release bearing: Correctly install the release bearing in the corresponding position on the input shaft of the transmission, and ensure that it can move smoothly. For some vehicle models, it is necessary to apply an appropriate amount of special grease to the contact area between the release bearing and the release fork to reduce friction. However, care should be taken not to apply too much, so as to prevent the grease from splashing onto the clutch disc and causing slippage. At the same time, it is necessary to ensure that the release fork and the release bearing are correctly engaged to form an integrated linkage structure.  •  Centering and concentricity of various components: During the installation process, it is necessary to ensure that there is good coaxiality between the clutch disc, pressure plate, flywheel, and the input shaft of the gearbox. A dedicated center positioning tool can be used to ensure accurate installation; otherwise, problems such as incomplete clutch disengagement and difficulty in shifting gears may occur.Precautions after Installation •  Clutch Pedal Adjustment: After the installation is completed, it is necessary to inspect and adjust the clutch pedal to ensure that its free travel and force meet the vehicle's technical requirements. Generally speaking, the free travel of the clutch pedal is usually between 15-25mm, and the specific value can be referred to in the vehicle's user manual.  •  Hydraulic System Bleeding: If it is a hydraulic clutch, after installation, the clutch hydraulic system should be bled to remove air from the system, ensuring the normal operation of the clutch pedal and the reliability of the hydraulic system. When bleeding, operate in the correct order and method to avoid air residue.Test run inspection: Start the engine, press and release the clutch pedal multiple times to check if the clutch disengages and engages smoothly, and if there are any jamming, abnormal noises, etc. At the same time, conduct a gear shifting test to feel if the gear shifting process is smooth and if the power transmission is normal. If there is any abnormality, it should be checked and troubleshooting should be carried out in a timely manner.
