As a commercial vehicle brand, FAW Jiefang’s clutch pressure plate and friction disc installation process shares the same core logic as most fuel-powered vehicles, but features commercial vehicle-specific specifications and torque requirements. Below is a detailed installation guide integrated with maintenance key points for models such as FAW Jiefang Xiaojiefang. Professional personnel and specialized tools are required for operation:
Vehicle and Accessory PreparationPark the vehicle on a solid, flat surface. Turn off the engine, engage the handbrake, shift to neutral, and securely lift the vehicle with professional lifting equipment. Inspect the new clutch pressure plate and friction disc to ensure no cracks, ablation, or other defects. Verify that the friction disc rivet sinkage does not exceed 0.3mm, the pressure plate diaphragm spring height difference is within 0.5mm, and the accessory model is compatible with the vehicle.
Tool and Cleaning PreparationPrepare socket wrenches, a torque wrench, a clutch friction disc alignment guide rod (special tool MD998127), Mitsubishi genuine grease (code 0101011) or equivalent alternative grease, and water-moistened cloths. Wipe the flywheel surface and transmission input shaft splines with a water-moistened cloth to remove oil and residues. Strictly prohibit sanding or dry brushing to avoid generating harmful debris.
Friction Disc Preparation and PositioningApply a uniform layer of special grease to the spline part of the clutch friction disc, then wipe off excess grease to prevent future slippage. Insert the alignment guide rod into the flywheel center, slide the friction disc onto the rod, and ensure the friction disc center is aligned with the flywheel center. Pay attention to the installation direction: the side marked "Flywheel Side" must face the flywheel—do not reverse it.
Pressure Plate Installation and SecuringPlace the new pressure plate over the friction disc and align the bolt holes. Hand-tighten the pressure plate mounting bolts in a crisscross pattern first, then use a torque wrench to tighten them evenly in two stages to FAW Jiefang’s specified torque of 1.9kg・m. This prevents pressure plate deformation from uneven force, which could affect subsequent clutch performance.
Auxiliary Component AssemblyApply special grease to the inner surface of the release bearing and its contact surface with the release fork. Install the release bearing in the corresponding position, ensuring smooth rotation without jamming. Next, install the release fork, allowing it to slide in the specified direction and engage with the return clip. Insert the release lever pin—avoid applying force in other directions to prevent damaging the return clip.
Transmission ReinstallationAdjust the transmission position to accurately align the input shaft with the friction disc splines. Push the transmission in smoothly—never force it to avoid spline damage. Subsequently, tighten the transmission mounting bolts in a crisscross pattern and reconnect previously disconnected wiring harnesses and other connectors.
System Inspection
For hydraulic clutch slave cylinders: Inspect internal components for damage. After assembly, check for oil leaks and complete the bleeding process.
Toggle the release fork repeatedly to test that the release bearing rotates smoothly and the friction disc slides without obstruction.
Test Drive AcceptanceStart the vehicle and test the clutch pedal travel for normal operation. Shift through all gears to check for smooth shifting. During low-speed driving, observe that clutch engagement and disengagement are smooth, with no judder, slippage, or abnormal noise. Avoid heavy loads during the initial operation period to allow full break-in between the friction disc and pressure plate, and further identify any installation issues.
The core precautions for installing the clutch pressure plate and friction disc of FAW Jiefang are: strictly matching accessory specifications, operating according to commercial vehicle-specific torque requirements, and keeping contact surfaces clean and free of contamination—avoiding early clutch damage caused by mismatches or improper operation. Specific key points are as follows:
Ensure accessories are accurately matched to the vehicle model. Focus on verifying the friction disc outer diameter, spline tooth count, and pressure plate bolt hole positions. Some heavy-duty FAW Jiefang models have thickness grading marks on the friction disc; select the one consistent with the original vehicle specifications.
Inspect the flywheel end face. If wear grooves exceed 0.5mm in depth, flatness deviation exceeds 0.2mm, or thermal cracks exist, the flywheel must be repaired or replaced first. Otherwise, it will cause uneven pressure on the pressure plate and abnormal wear of the friction disc.
Calibrate specialized tools in advance, especially the torque wrench, to ensure accurate torque output. The alignment guide rod must fit tightly with the flywheel center hole to avoid positioning deviations.
Strictly prohibit oil or grease contamination on the mating surfaces of the friction disc, pressure plate, and flywheel. Clean only with a water-moistened cloth—never use strong solvents such as gasoline or diesel—to prevent reduced friction coefficient and subsequent slippage.
Never reverse the friction disc installation direction. The side with damping springs or marked "Flywheel Side" must face the flywheel. Reversing it will result in incomplete clutch release and abnormal pedal travel.
Bolt tightening must follow the process: "crisscross pre-tightening → two-stage tightening → torque compliance". The pressure plate fixing bolt torque must strictly adhere to 1.9kg・m; do not arbitrarily increase or decrease it to avoid pressure plate deformation.
Grease can only be applied to the spline hole, release bearing, and release fork contact points, with an appropriate amount. Excess grease must be wiped clean to prevent contamination of the friction surface after melting at high temperatures.
After installing the release bearing, ensure the axial clearance is between 0.3-0.5mm, with smooth rotation and no abnormal noise. For heavy-duty models, additionally check the rigidity of the release fork to avoid deformation under stress.
Thoroughly bleed the hydraulic clutch slave cylinder. Repeatedly press the pedal until no air bubbles are discharged. Control the pedal free travel between 15-20mm to ensure reliable release under heavy-load conditions.
During assembly, check the locating pins of the clutch housing and flywheel housing to ensure they are properly installed. This prevents misalignment between the transmission input shaft and the friction disc splines, which can cause difficulty shifting gears.

J7 Clutch Maintenance Manual available on
Docin.com elaborates on key installation parameters for models such as the Jiefang CA4250P77K25T1E5, including the assembly sequence of the clutch cover assembly and driven disc assembly (including the friction plate), the bleeding procedure for the hydraulic system, and the bolt tightening torque. Similarly, the FAW Light Jiefang Clutch Maintenance Manual on Renren Library clearly specifies maintenance standards such as the rivet sinkage of clutch friction plates and relevant specifications for pressure plates. It also outlines requirements for installation tools like the designated grease and clutch centering mandrel, which are highly consistent with the content concerning such installation methods and precautions.
Specialized works such as Structure and Maintenance of Jiefang Medium - sized Diesel Transport Vehicles published by China Machine Press systematically expound on the clutch structure and maintenance knowledge of Jiefang series diesel transport vehicles. Inevitably, they cover the installation specifications and inspection key points for clutch pressure plates and friction plates, acting as important reference sources for such maintenance content.
Automotive maintenance columns on platforms like PCauto integrate universal clutch installation processes for various vehicle models including those of FAW Jiefang. Examples of the key points covered are the diagonal tightening of pressure plate bolts, the centering during friction plate installation, and the pedal adjustment after installation. Meanwhile, document repositories such as Jinchutou Library also include clutch maintenance documents for FAW Light Jiefang, supplementing details like taboos for component disassembly and wear limits. Such content often serves as practical supplementary references to official manuals.
