FAW Clutch And Fastener Logic Assembly: An Expert Analysis of Its 5 Componentes principais

Welcome to this expert analysis of the FAW Clutch And Fastener Logic Assembly, the complete system responsible for engaging and disengaging engine power for the FAW Jiefang CA4251P66K24T1A3E5 6×4 diesel semi-trailer tractor.

This system is the critical link between the engine’s flywheel and the transmission’s input shaft. O FAW Clutch And Fastener Logic Assembly é a “logic” system because its components are designed to perform a specific mechanical sequence: clamp with immense force, release with minimal effort, and re-engage smoothly.

This guide is an essential resource for professional technicians, fleet managers, and parts specialists. We will deconstruct the entire FAW Clutch And Fastener Logic Assembly into its 5 serviceable units, including the pressure plate, the driven plate (friction disc), the release bearing, and the critical fasteners that secure the system.

Core Component 1: The Clutch Cover Assembly (1601310-54C)

The ‘Clutch Cover Assembly’ (1601310-54C) is the “clamping” part of the FAW Clutch And Fastener Logic Assembly. This component is commonly known as the **pressure plate**. It is a heavy-duty cast iron housing that contains a massive, high-force diaphragm spring.

This entire assembly is bolted directly to the engine’s flywheel, spinning at the same speed as the engine. Its “default” state is **engaged**. The powerful diaphragm spring exerts thousands of pounds of clamping force, pinning the ‘Clutch Driven Plate’ (the friction disc) between itself and the flywheel. This is what creates the 1:1, no-slip connection that transfers all the engine’s torque to the transmission.

O “logic” of the FAW Clutch And Fastener Logic Assembly begins here. When the driver presses the clutch pedal, the ‘Clutch Release Bearing’ (1601430-99A) pushes on the center “fingers” of this diaphragm spring. This action, through leverage, *retracts* the pressure plate surface, releasing the clamping force and allowing the friction disc to spin freely. The health of this spring is key to the FAW Clutch And Fastener Logic Assembly‘s ability to hold torque.

Core Component 2: The Clutch Driven Plate (1601210-54C)

The ‘Clutch Driven Plate Assembly’ (1601210-54C) is the component most people recognize as the “clutch disc.” This is the only “wear item” in the FAW Clutch And Fastener Logic Assembly and is the part that transfers the power. It is a large, circular disc with a splined hub that slides onto the transmission’s input shaft.

On both sides, this disc is lined with a high-friction, high-temperature material, similar to a brake pad. These “facings” are what get “clamped” between the flywheel and the pressure plate. When clamped, this disc connects the (engine-driven) flywheel to the (transmission-driven) input shaft, forcing them to spin as one unit.

This component of the FAW Clutch And Fastener Logic Assembly is also a sophisticated damper. The hub of the disc contains a set of large **torsional springs**. These springs absorb the engine’s harsh combustion pulses and the shock of engagement, fornecendo a “cushion” to the driveline. This prevents jerky starts and protects the transmission’s gears from shock-loading.

Ao longo do tempo, the friction material on this disc wears away, just like a brake pad. When it becomes too thin, it can no longer be clamped with sufficient force. This results in “clutch slip,” where the engine RPMs rise, but the truck fails to accelerate. This is the most common failure of the FAW Clutch And Fastener Logic Assembly and requires the replacement of this disc (and usually the cover and bearing as well).

Core Component 3: The Release Bearing (1601430-99A)

The ‘Clutch Release Bearing Assembly’ (1601430-99A) is the “actuator” in the FAW Clutch And Fastener Logic Assembly. This component is commonly known as the “throw-out bearing.” It is a high-thrust bearing designed to perform one critical task: transfer the “push” from the stationary clutch fork to the spinning diaphragm “fingers” of the pressure plate.

When the driver presses the clutch pedal, a (hydraulic or mechanical) fork pushes this bearing forward. The bearing’s face makes contact with the spinning pressure plate fingers. Because it is a bearing, its outer “race” can spin along with the pressure plate, while its inner “race” remains stationary with the fork.

This forward push is what “releases” the clutch. This bearing must withstand immense thrust loads (thousands of pounds) every time the clutch is pressed. A common failure mode for this part of the FAW Clutch And Fastener Logic Assembly is wear, which results in a “chirping” ou “grinding” noise when the clutch pedal is pressed. Because replacing it requires removing the entire transmission, it is *always* replaced as part of a complete FAW Clutch And Fastener Logic Assembly service.

O “Fastener” Logic: Parafusos (CQ1501070T) and Gaskets (Q40310)

The final components are the “Fasteners” in the FAW Clutch And Fastener Logic Assembly. The parts list calls for 12 ‘Hex head guide bolts’ (CQ1501070T) e 12 ‘Spring Gaskets’ (Q40310).

These are the **critical fasteners** that secure the ‘Clutch Cover Assembly’ (pressure plate) to the engine’s flywheel. The ‘Hex head guide bolt’ is a high-tensile, Class 10.9 ou 12.9 parafuso. O “guide” ou “dog point” on the end of the bolt helps to align the heavy cover during installation, preventing thread damage.

O 12 ‘Spring Gaskets’ (Q40310), ou “lock washers,” are just as important. They exert constant spring tension on the bolt head, preventing the bolts from vibrating loose. O FAW Clutch And Fastener Logic Assembly is in a state of constant, high-frequency vibration from the engine. Without these lock washers, the pressure plate bolts could back out, leading to imbalance, catastrophic failure, and destruction of the bell housing.

O “logic” of these fasteners is that they must be torqued gradually, in a specific “star” ou “crisscross” padrão. This is essential to draw the pressure plate down evenly, without warping its housing or damaging the new friction disc. Esse FAW Clutch And Fastener Logic Assembly‘s performance is completely dependent on this correct installation procedure.
