Ventilador FAW J6P: Deconstruyendo 10 Piezas críticas para una refrigeración impecable del motor

Welcome to this definitive technical deconstruction of the Ventilador FAW J6P and fan clutch assembly. This guide provides an expert analysis of the complete fan system for the FAW Jiefang CA3250P66K2L1T1E 6×4 heavy-duty diesel dump truck. Engineered for professional technicians, administradores de flotas, y especialistas en repuestos, this document breaks down the entire 10-component assembly from its largest structural elements, such as the fan and clutch, to its smallest, aún crítico, unidades reparables, including every specialized fastener, lavadora, and flange.

The thermal management system on the CA3250P66K2L1T1E is designed for extreme, low-speed, high-load conditions. Unlike highway trucks, a dump truck operates at maximum engine power with minimal vehicle speed, resulting in zero aire ram. In these scenarios, the engine’s survival is 100% dependent on the Ventilador FAW J6P to mechanically pull thousands of cubic feet of air through the radiator, preventing catastrophic overheating.

Centro 1: El “Air Movement” Lógica (The FAW J6P Fan)

Este grupo representa el músculo del sistema. Its logic is straightforward: convert the rotational energy delivered by the clutch into a high-volume, high-velocity column of air. This is the primary job of the Ventilador FAW J6P.

1. Componente: ‘Fan assy’ (1308010-14B)
Este (compensación 4) is the ‘Fan Assembly’ and is the most prominent component of the Ventilador FAW J6P sistema. This is not a lightweight component; it is a heavy-duty, multi-blade unit, likely fabricated from high-strength, glass-reinforced composite or precision-stamped steel.

El Blade Pitch Logic is its most critical design feature. The specific angle, depth, curvatura, and number of blades are not arbitrary. They are the result of extensive fluid dynamics engineering to find the “sweet spot” that maximizes airflow (medido en CFM), while simultaneously minimizing noise and the horsepower required to spin it (parasitic drag).

El Lógica de ensamblaje is a crucial service consideration. The part is designated ‘Fan assy’ (asamblea), which signifies it is a single, factory-balanced, non-serviceable component. The blades are permanently affixed to a central hub, as the entire Ventilador FAW J6P unit is dynamically balanced to extremely tight tolerances.

At high rotational speeds, even a minor imbalance—such as from a small crack or a bent blade—would induce destructive, high-frequency vibrations. These vibrations would lead to the rapid failure of the ‘Fan clutch assy’ (compensación 8) aspectos. For this critical safety reason, if any part of the fan blade is damaged, the *entire* ‘Fan assy’ (compensación 4) debe ser reemplazado.

Centro 2: El “Smart Engagement” Lógica (The FAW J6P Fan Clutch)

Este grupo representa el cerebro del sistema. Its entire purpose is to intelligently decouple the fan from the engine’s drive pulley, ensuring the fan only spins when it is absolutely needed. Este es el “elegante” parte del Ventilador FAW J6P.

1. Componente: ‘Fan clutch assy’ (1313010-65D)
Este (compensación 8) is the ‘Fan Clutch Assembly’, the most complex and vital component in this group. For a heavy-duty application like this, es un Viscous Clutch, el corazón de la Ventilador FAW J6Pla lógica.

El Viscous Logic is a marvel of non-electric, thermomechanical engineering. Mounted on the front of the clutch is a bi-metallic thermostatic spring. This spring is positioned directly in the airstream *after* it has passed through the radiator. Its ‘logic’ is to read the temperature of the air coming *off* the radiator, which is a direct proxy for coolant temperature.

As this air temperature rises (P.EJ., above 85°C), the spring’s metals expand at different rates, causing it to coil. This physical movement mechanically opens a small internal valve. This valve releases a specialized, high-viscosity silicone fluid from a storage reservoir into a working chamber. This chamber contains intricate, alternating plates—one set connected to the input shaft and the other to the output body (which holds the Ventilador FAW J6P).

El corte fluido of this thick fluid between the spinning plates transfers torque. The hotter the air, the more the valve opens, the more fluid enters, and the faster the fan spins. Este es el Progressive Engagement Logic; it is not a simple on/off switch. Permite el Ventilador FAW J6P to spin at a variable speed, precisely matching the engine’s real-time cooling demands. When the radiator air cools, the spring closes the valve, the fluid is pumped back to the reservoir, y el ventilador se desconecta.

2. Componente: ‘Fan clutch transition flange’ (1313063-14B)
Este (compensación 10) es el critico Lógica de interfaz componente, or adapter flange. The ‘Fan clutch assy’ (compensación 8) is a specialized unit, but the engine’s pulley hub has its own standardized bolt pattern.

This ‘Transition Flange’ is the essential, high-strength steel adapter that bridges the gap. It is precisely machined to bolt flat against the engine’s pulley hub (using ‘Combination bolts’, compensación 9) and provide the exact mounting face required by the ‘Fan clutch assy’. It must transfer 100% of the drive torque and maintain perfect concentricity to prevent vibration in the Ventilador FAW J6P asamblea.

Centro 3: El “Montaje & Cierre” Lógica (Securing the FAW J6P Fan)

This final group contains all the serviceable hardware. It is the most frequently overlooked yet is absolutely critical for safety. Es lógica is to manage three primary forces: high rotational torque, constant engine vibration, and thermal cycling. Using generic, non-specified hardware for a Ventilador FAW J6P puede conducir a un fracaso catastrófico, where the fan assembly can detach while the engine is running.

1. El “Fan-to-Clutch” Grupo (compensación 1, 2, 3)
This sub-assembly includes: «Tuerca hexagonal’ (CQ34008, Cantidad 6), 'arandela de resorte’ (Q40308, Cantidad 6), and ‘Washer’ (Q40108, Cantidad 6). Este es el Sandwich Logic used to mount the ‘Fan assy’ (compensación 4) onto the front of the ‘Fan clutch assy’ (compensación 8), a critical joint for the Ventilador FAW J6P.

El Lavadora (compensación 3) is a ‘flat washer,’ proporcionando una amplia, flat surface area. Its logic is to distribute the clamping load of the nut and prevent it from pulling through the fan’s composite or steel mounting holes. El arandela de resorte (compensación 2) is the most critical part. It is a high-tension lock washer providing Anti-Vibration Pre-load; it actively pushes against the nut, maintaining tension and preventing it from backing off under constant, vibración de alta frecuencia.

2. El “Clutch-to-Flange” Grupo (compensación 5, 6, 7)
Este grupo incluye: «Perno prisionero’ (CQ1201030, Cantidad 4), 'arandela de resorte’ (Q40310, Cantidad 4), y «tuerca hexagonal’ (CQ34010, Cantidad 4). Este es el Serviceable Mount Logic. The ‘Stud bolts’ (compensación 5) are likely threaded permanently into the ‘Fan clutch assy’ (compensación 8) sí mismo.

This design is intentional. It allows a technician to easily ‘hang’ the heavy clutch assembly onto the studs, which protrude through the ‘Transition flange’ (compensación 10). This holds the component in place, freeing the technician’s hands to easily install the ‘Spring washers’ (compensación 6) and ‘Hexagon nuts’ (compensación 7) without having to align bolt holes while supporting the component’s full weight. This design is crucial for field serviceability for the Ventilador FAW J6P.

3. El “Flange-to-Engine” Grupo (compensación 9)
Este grupo incluye: «Perno combinado’ (CQ1421040, Cantidad 6). Este es el Assembly Line Logic. A ‘combination bolt’ (or ‘combi-bolt’) is a specialized fastener that has a captive, free-spinning washer (en este caso, a spring washer) pre-installed on the bolt.

This feature is crucial for both the factory and field service. It makes installation faster (one part, not two) and makes it *impossible* to forget or drop the all-important spring washer. These six bolts secure the ‘Transition flange’ (compensación 10) to the engine’s pulley hub, transfiriendo 100% of the drive power from the belt to the entire Ventilador FAW J6P sistema.
