Welcome to this expert technical guide on the Generador FAW asamblea (Número de pieza. 3701010-36D), the core of the electrical power system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. This component is essential for all vehicle operations.
El Generador FAW, technically an AC (Alternating Current) Generator or “alternador,” is a high-output component responsible for two critical tasks: it recharges the truck’s batteries and provides all the electrical power needed to run the engine’s ECU, inyectores de combustible, iluminación, climatización, and all other onboard electronics.
This guide is an essential resource for professional technicians and fleet managers. Although the parts list is simple, it represents a complex system. Deconstruiremos todo Generador FAW asamblea, its internal logic, and its critical mounting hardware, down to the smallest serviceable unit.
The main component is the ‘AC Generator Assembly’ (3701010-36D), cual es el completo Generador FAW unidad. Este es un trabajo pesado, high-amperage alternator (probable 100 amps or more at 24 volts) specifically designed for the demands of a commercial tractor. Its function is to convert mechanical energy from the engine’s serpentine belt into usable DC electrical energy.
El Generador FAW is not a simple motor. It operates by spinning an electromagnet (the **Rotor**) inside a fixed set of wire coils (the **Stator**). As the engine spins the generator’s pulley, the magnetic field of the rotor “cuts” across the stator windings, inducing an Alternating Current (C.A.) in the stator. This AC is the raw power generated by the unit.
This AC is not usable by the truck’s 24-volt DC system. Por lo tanto, el “lógica” del Generador FAW lies in its two internal electronic components: the rectifier and the voltage regulator. These components are typically housed inside the rear cover of the Generador FAW asamblea.
A key part of the Generador FAW assembly is the **Rectifier Bridge**. This is a solid-state electronic component, typically a set of six or more high-power diodes. These diodes act as one-way electrical valves. They capture the AC sine wave from the stator windings (which swings from positive to negative) y “flip” the negative half, converting the entire output into a pulsating Direct Current (corriente continua). This DC is what is sent to the battery and the rest of the truck.
The **Voltage Regulator** is the “cerebro” del Generador FAW. The truck’s electrical system is extremely sensitive and demands a constant voltage (P.EJ., ~28.4 volts for a 24V system) to safely charge the batteries and power the ECU. Sin embargo, el Generador FAW‘s output is directly tied to engine speed; it produces less voltage at idle and far too much at high RPM.
The regulator solves this. It constantly monitors the battery voltage. If the voltage drops below the target (P.EJ., 28.4V), the regulator sends *more* electrical current to the spinning rotor via a set of “slip rings” y “brushes.” This makes the rotor’s electromagnet *stronger*. A stronger magnetic field induces more power in the stator, and the voltage rises.
En cambio, if the voltage climbs *above* the target, the regulator sends *less* current to the rotor. The electromagnet weakens, less power is induced, and the voltage drops. This constant feedback loop, happening hundreds of times per second, is what provides the stable, “regulated” Voltaje. A failure in the regulator is a common reason for replacing a Generador FAW, as it can lead to dead batteries (under-charging) or a fried ECU (over-charging).
La lista de piezas para el Generador FAW assembly details its mounting hardware. This is a critical system, as the generator is a heavy component that is under a constant, high-tension side-load from the serpentine belt.
El 'perno – para fijar generador de CA’ (3701327-36D), de los cuales hay dos, are the main fasteners. On a heavy-duty Generador FAW, this is often a “semental” sistema. These studs are threaded into the engine’s main mounting bracket. The generator is then slid onto these studs.
La 'tuerca de seguridad con brida de cabeza hexagonal’ (CQ32610) is the key to securing the Generador FAW. The list calls for two nuts, matching the two studs. These are not simple nuts; they are **flange lock nuts**.
**Brida:** The base of the nut is “bridado,” meaning it has a wide, lavadora integrada. This washer distributes the clamping force over a wider area of the Generador FAW‘s aluminum mounting ears, preventing it from cracking.
**Cerrar:** The nut is a “tuerca de bloqueo,” meaning it is “prevailing-torque.” It is either “top-lock” (distorted at the top) o “nylon-insert” (though less common in high-heat areas). This design means the nut actively resists backing off from the intense vibration of the diesel engine. A standard nut would vibrate loose, causing the Generador FAW to lose belt tension and stop charging.
This robust stud-and-lock-nut system is what allows the Generador FAW to be securely mounted, but also allows it to pivot on one of the bolts, which is necessary for setting the proper serpentine belt tension.
