The installation of the clutch pressure plate for Hyundai vehicles shall follow the process of "Cleaning → Centering → Diagonal Step-by-Step Tightening → Lubrication → Inspection". The key lies in correct orientation, proper concentricity, accurate torque application, and adequate lubrication to ensure smooth engagement, complete disengagement, and no abnormal noise.
Park the vehicle on a level surface, engage the parking brake, shift to neutral, and disconnect the negative battery terminal.
Securely support the vehicle with a lift or jack + safety stands; remove the transmission.
Torque wrench, socket set, Phillips/flathead screwdrivers, clutch centering tool (e.g., Hyundai special tool SST 09411-1P000), lithium-based grease, new pressure plate, clutch disc, release bearing, pilot bearing, etc.
Thoroughly clean the flywheel face, pressure plate mounting surface, and locating pins to ensure no oil contamination, rust, burrs, or debris.
Inspect the flywheel ring gear, pilot bearing, release bearing, and fork; replace if necessary. Verify that the new pressure plate and clutch disc are model-compatible.
Confirm the driven disc orientation: The side with the damper/cushion spring seat faces the pressure plate. Most Hyundai models are marked with "TM SIDE" (Transmission Side) and "FLYWHEEL SIDE" — strictly follow these markings.
Insert the centering tool or transmission input shaft through the driven disc spline hub and pilot bearing to maintain concentricity with the flywheel and prevent displacement.
Align the pressure plate with the flywheel’s locating pins/holes; ensure correct orientation. Align assembly marks (e.g., arrows, notches) with corresponding marks on the flywheel if present.
Install the pressure plate mounting bolts, hand-tighten until snug (do not fully tighten yet).
Tighten the bolts gradually in a diagonal sequence over 2–3 stages to avoid pressure plate deformation.
Torque reference for common Hyundai models: 24.5–34.3 N·m (e.g., Sonata); approximately 25 N·m for some models. Always refer to the official service manual for exact specifications.
Apply lithium-based grease to the release bearing inner race, fork contact points, release fork shaft ends, locating pins, and bolt threads to prevent dry friction and abnormal noise.
Clean the transmission input shaft splines, apply a thin layer of grease, and carefully insert it into the driven disc spline hub (avoid impact).
Tighten the transmission-to-engine mounting bolts to the specified torque. Connect the clutch hydraulic line/cable, fill with fluid, and bleed the system (for hydraulic clutches).
Free Travel: Reference range for some Hyundai models: 6–13 mm (e.g., Sonata); 15–25 mm for others. Confirm with the service manual.
Total Travel: e.g., Sonata: 145±3 mm. Ensure complete disengagement.
Verify smooth startup, seamless gear shifting, and no slipping, vibration, or incomplete disengagement. Address any abnormalities immediately.
(Focusing on safety standards, precision control, and fault prevention, suitable for professional maintenance scenarios)
The vehicle must be double-secured with a lift or jack + safety stands; never perform operations relying solely on a jack. Wedge the wheels with chocks to prevent rolling.
Disconnect the negative battery terminal (to avoid short circuits from accidental contact with electrical components). Before removing the transmission, disconnect relevant sensor connectors (e.g., reverse radar, vehicle speed sensor) and mark them clearly to prevent incorrect reconnection.
Calibrate the torque wrench for accuracy before use; ensure the socket matches the bolt size (to prevent thread stripping). During installation/removal, never insert hands into the gap between the flywheel and pressure plate to avoid crushing injuries.
Maintain a dust-free and oil-free work area to prevent impurities from adhering to the friction surfaces of the flywheel and pressure plate (which will affect clutch engagement performance).
The side with the damper spring seat must face the pressure plate. Hyundai models are marked with "TM SIDE" (Transmission Side, facing the transmission) and "FLYWHEEL SIDE" (facing the flywheel). Reversing the orientation will cause disengagement failure and gear-shifting shock.
Fully align the locating pins with the flywheel holes. If there are assembly marks (e.g., arrows, notches), they must align with the corresponding marks on the flywheel to avoid pressure plate tilting.
Use a clutch centering tool throughout the process (Hyundai special tool SST 09411-1P000 or universal type) to ensure concentricity between the driven disc, flywheel, and crankshaft. Failure to do so will result in difficulty installing the transmission input shaft, or cause uneven wear of the driven disc and clutch vibration.
Insert the centering tool through the driven disc spline hub and crankshaft pilot bearing, and only remove it after the pressure plate bolts are fully tightened.
Tighten the bolts gradually in a diagonal pattern over 2–3 stages. Never tighten them all at once or in the wrong sequence (this will cause pressure plate deformation and uneven friction surfaces).
Strictly follow the torque specifications in the vehicle service manual (24.5–34.3 N·m for common Hyundai models; 40–50 N·m for some performance models). Insufficient torque may lead to bolt loosening, while excessive torque can cause pressure plate cracks and thread stripping.

The content of the aforementioned precautions is primarily derived from the following authoritative and practical sources, which can be used as references and verification bases:
Key Bases: The centering tool model (SST 09411-1P000), driven disc orientation marks ("TM SIDE"/"FLYWHEEL SIDE"), diagonal step-by-step tightening requirements for pressure plate bolts, torque specifications (24.5–34.3 N·m), lubrication points for the release bearing and fork, and installation/inspection standards for the pilot bearing are fully consistent with Hyundai’s original factory service manual.
Applicable Models: Mainstream manual transmission models such as Elantra (CN7) 2021–2025, Sonata, Verna, and Lavida (Langdong).
Access Channels: Technical departments of authorized Hyundai dealers, original factory electronic maintenance systems (e.g., GDS), or paper/electronic manuals from compliant channels.
The centering tool SST 09411-1P000 is an official special tool designated by Hyundai, used to ensure concentricity between the driven disc, flywheel, and crankshaft, preventing uneven wear or vibration after installation.
Bolt torque values, release bearing preload dimensions (e.g., A=18mm), and concentricity requirements for the release fork shaft are all sourced from Hyundai’s technical bulletins or maintenance specification documents.
Practices such as diagonal step-by-step tightening of pressure plate bolts, oil prohibition on friction surfaces, component orientation verification, post-installation clutch pedal free travel adjustment (6–25 mm), and hydraulic system bleeding procedures are industry consensus, complying with relevant SAE and ISO maintenance operation standards.
Maintenance Q&As and tutorials on platforms such as Autohome and PCauto summarize common fault cases and installation key points of Hyundai models (e.g., disengagement failure caused by reversed driven disc installation, pressure plate deformation due to improper torque), which can serve as practical references.
Most content is compiled based on owner feedback and maintenance experience, with some parameters (e.g., 25 N·m torque, 15–25 mm free travel) consistent with the service manuals of certain Hyundai models.
Excerpts of Hyundai vehicle maintenance manuals (e.g., 2012 Sonata 2.0 DOHC, 2013 Lavida 1.6 MPI) on platforms such as Originality Documents and Renren Library provide detailed steps for clutch system disassembly, installation, and adjustment, which are highly consistent with the content of official manuals.
