The clutch assembly’s ability to manage immense engine power relies on a robust pressure mechanism. As a core component among genuine Sinotruk howo parts, the Clutch Plate (Pressure Plate), identified by OEM number LG9704160528, is critical for power transfer. This plate applies clamping force to secure the clutch disc against the flywheel. The genuine LG9704160528 is engineered to withstand the high torque and thermal stress of heavy-duty operation. It ensures reliable engagement and disengagement for smooth gear shifts and long service life.
Clutch Plate

The Clutch Plate, part number LG9704160528, is the clutch cover assembly or pressure plate. It is bolted directly to the engine flywheel. Its primary function is to clamp the clutch disc between itself and the flywheel. This creates the friction needed to transmit engine torque.
When the clutch pedal is released, the LG9704160528 plate exerts strong spring pressure. This locks the disc in place. When the pedal is pressed, the release bearing acts on the plate’s diaphragm spring. This releases the clamping force, allowing gear changes.
The design of the genuine LG9704160528 is crucial. It must apply even pressure across the entire disc surface. It must also dissipate heat effectively. A warped or weak pressure plate leads to clutch slippage and rapid wear.
High-Clamping Force & Torque Capacity
The LG9704160528 features a heavy-duty diaphragm spring designed to exert consistent, high clamping force, ensuring no power loss through slippage under load.
Superior Heat Resistance and Dissipation
Constructed from high-grade cast iron or steel, it resists warping and thermal fatigue, maintaining its shape and function under extreme clutch heat.
Precision-Machined for Even Contact
The friction surface is machined to exact flatness specifications, ensuring uniform pressure distribution on the clutch disc for smooth engagement and long life.
Durable Spring and Lever Mechanism
The diaphragm spring and release levers are engineered for millions of cycles without fatigue, providing reliable and consistent clutch action over time.

A failing clutch pressure plate, part LG9704160528, shows distinct symptoms. Clutch slippage under acceleration is a primary sign. The engine revs climb but vehicle speed does not increase proportionally. This indicates insufficient clamping force.
Difficulty shifting gears, especially grinding during engagement, is common. A chattering or shuddering sensation when releasing the clutch pedal indicates a warped plate. A burning smell from the clutch area points to overheating.
Unusual noises from the clutch housing, like rattling or squealing, may occur. The clutch pedal may feel abnormally heavy or have a spongy feel. These symptoms suggest the LG9704160528 plate requires inspection and likely replacement.
Continued use with a faulty pressure plate damages the clutch disc and flywheel. It can lead to complete clutch failure and vehicle immobility. Prompt diagnosis and replacement with a genuine LG9704160528 part are essential.
Replacing the clutch pressure plate is a significant task requiring transmission removal. Safely support the vehicle and disconnect the battery. Remove the driveshaft, shift linkages, and clutch hydraulic line or cable.
Support the transmission and unbolt it from the engine bellhousing. Carefully lower it to access the clutch assembly. Mark the orientation of the old LG9704160528 plate relative to the flywheel for reference.
Unbolt the pressure plate evenly in a star pattern. Remove the old clutch disc and plate. Thoroughly clean the flywheel surface. Install the new genuine LG9704160528 plate using a clutch alignment tool.
Torque the bolts in a star pattern to the manufacturer’s specification. Reinstall the transmission and all components. Adjust the clutch free play and bleed the hydraulic system if necessary. A proper break-in period is crucial for longevity.
The pressure plate is the active component that makes and breaks the clutch connection. Its spring force determines the clutch’s torque-holding capacity. The LG9704160528 must balance strong clamping with smooth release action.
A well-designed plate reduces driver fatigue by providing consistent pedal effort. It also protects the driveline by allowing smooth, progressive engagement. Its thermal management prevents heat-induced failure during heavy use.
Therefore, the LG9704160528 is not a passive component. It is an engineered system of springs, levers, and friction surfaces. Its quality directly impacts the durability of the entire clutch assembly and driving experience.
The genuine LG9704160528 pressure plate is manufactured to exact OEM specifications. The spring rate is calibrated for the specific SINOTRUK Howo model. This ensures correct pedal feel and engagement characteristics.
The metallurgy of the casting and spring is controlled for strength. It resists warping under high thermal loads. Non-genuine plates may use inferior materials that fatigue or warp quickly. This leads to premature clutch failure.
The genuine LG9704160528 also guarantees perfect dimensional accuracy. This ensures proper alignment with the flywheel and release bearing. Using the OEM part is an investment in reliable performance and safety.
The Clutch Plate (Pressure Plate), OEM number LG9704160528, is the powerhouse of the clutch assembly. Its ability to reliably clamp and release defines the functionality of the entire clutch system.
Choosing the genuine LG9704160528 part guarantees the clamping force, heat resistance, and durability required for the toughest hauling jobs. Ensure your SINOTRUK Howo delivers power efficiently and reliably by trusting only authentic OEM components for clutch service.
