Este guia detalha o 57 componentes reparáveis, from the main reducer to the differential lock, detailing the parts required for a full service and rebuild of this critical assembly.

O Eixo traseiro FAW J6P é um serviço pesado, single-reduction axle with an integrated differential lock, designed for extreme-duty applications. Isso é 5.263 final drive ratio (io=5.263) provides immense torque multiplication, which is essential for off-road and heavy-haul scenarios. This deconstruction will analyze the complete assembly, focusing on the serviceable units that technicians must manage to ensure the longevity and reliability of the entire drivetrain. We will explore the input pinion, o diferencial, the locking mechanism, and the axle shafts, all of which form the complete Eixo traseiro FAW J6P sistema.

Essencial 1: O “Entrada & Redutor” Lógica (O conjunto do pinhão)

This group forms the input section of the Eixo traseiro FAW J6P. It receives power from the driveshaft and performs the first and primary stage of gear reduction (io=1.333). This assembly’s precise setup is critical for the axle’s lifespan.

1. Componente: ‘Main reducer assy’ (2402010AA6E) – Quantidade 1
Esse (Comp part) is the complete input pinion and gear set. Este é o coração do Eixo traseiro FAW J6P‘s reduction. É um usinado com precisão, conjunto correspondente, meaning the pinion gear and the main ring gear (Comp. 39) must be replaced together to ensure perfect tooth contact.

2. Componente: Consequência & Grupo de Apoio (32315, 2402049-A0E, 2402048-A0E)
Este grupo (Comp. 11, 13, 12) is the set of tapered roller bearings and oil thrower that support the pinion shaft. O Lógica de rolo cônico é crítico. These bearings must handle massive axial (impulso) and radial (lateralmente) loads simultaneously. O Eixo traseiro FAW J6P relies on these heavy-duty bearings for rigid pinion alignment under torque.

3. Componente: ‘Adjustment shim-main reducer driven pinion’ (2402097~99-A0E) – Quantidade conforme solicitação.
Esse (Comp. 9) é um conjunto de calços de precisão, fornecido em espessuras como 0,5 mm, 0.15milímetros, e 0,10mm. O Lógica de pré-carga do pinhão is the most critical assembly step. Esses calços são usados ​​para definir o torque de rotação preciso (pré-carregamento) nos rolamentos do pinhão. An incorrect shim pack will cause the bearings on the Eixo traseiro FAW J6P input to fail very quickly, levando a danos catastróficos.

4. Componente: Selo & Flange Group (2402055-A0E, 2402067-A0E, 2402036AA6E)
This group includes the main ‘Oil seal-driven pinion’ (Comp. 18) and ‘Dust cap’ (Comp. 19). This system prevents gear oil from leaking out and contaminants (sujeira, água) from entering the Eixo traseiro FAW J6P habitação. The ‘Flange-main reducer’ (Comp. 10) is what connects to the driveshaft, secured by the ‘Nut’ (Comp. 22).

Essencial 2: O “Diferencial & Trancar” Lógica (Torque Distribution)

This assembly is the ‘brain’ do Eixo traseiro FAW J6P. It manages the torque split between the left and right wheels and houses the driver-controlled differential lock, which is essential for navigating low-traction environments.

1. Componente: 'Conjunto diferencial’ (2403015-A0E) – Quantidade 1
Esse (Comp A) is the complete differential carrier, which includes the case halves (‘Left case-differential’ 2403017-A0E and ‘Right case’ 2403018-A0E) and all internal gears. This entire unit is bolted to the main ring gear (Comp. 39).

2. Componente: Spider & Gear Group (2403061-A0E, 2403056-A0E, 2403051-A0E)
Este grupo (Comp. 47, 46, 49) includes the ‘Cross’ (aranha), the ‘Planetary gear’ (engrenagens de aranha), and the ‘Half shaft gear’ (engrenagens laterais). Esse Lógica Planetária is what allows the wheels to rotate at different speeds when turning. O Eixo traseiro FAW J6P uses a robust 4-pinion design for maximum strength under load.

3. Componente: Differential Lock Group (2406024~34-A0E)
Esse (Comp. 24-27) is the air-actuated locking mechanism. It includes the ‘Fork-diff lock’ (Comp. 24), 'Manga deslizante’ (Comp. 25), and ‘Fixed sleeve’ (Comp. 26). When the driver activates the ‘Switch assy-diff lock’ (Comp. 37), air pressure moves the fork, which slides the sleeve to lock the differential. Isso faz com que Eixo traseiro FAW J6P a ‘solid’ eixo, forçando ambas as rodas a girar na mesma velocidade.

4. Componente: ‘Cilindro de ar’ & 'Pistão’ (2406016-A0E, 2406014-A0E)
Esse (Comp. 35, 31) is the external actuator. The ‘Air cylinder’ receives air from the ‘Hose connector’ (Comp. 36) and pushes the ‘O type ring-diff lock piston’ (Comp. 31), which in turn moves the lock fork. This is the activation system for the Eixo traseiro FAW J6P differential lock.

Essencial 3: O “Fundação & Saída” Lógica (Habitação & Shafts)

This group represents the foundation of the entire assembly and the final components that deliver power to the wheel hubs. The strength of these parts is paramount for the Eixo traseiro FAW J6P‘s load-bearing and torque-handling capabilities.

1. Componente: ‘Rear axle housing’ (2401011-A6E) – Quantidade 1
Esse (Comp. 2) is the main structural backbone. It holds the differential, contains the lubricating oil, and supports the vehicle’s load. It also features the ‘Breather’ (Comp. 4) and ‘Plug-magnetic’ (Comp. 5, T62104M) para manutenção. O Eixo traseiro FAW J6P housing is a massive cast component built to withstand extreme punishment.

2. Componente: ‘Pinhão acionado’ (2402037AA6E) – Quantidade 1
Esse (Comp. 39) is the main ‘ring gear’. It is bolted to the differential case (Comp A) using 18 high-strength ‘Bolt-fastening reducer’ (Comp. 7). This gear is a matched set with the input pinion (Comp 2402010AA6E) and defines the final drive ratio of the Eixo traseiro FAW J6P.

3. Componente: ‘Left half shaft’ & ‘Right half shaft’ (2403081B483, 2403082B483)
Esses (Comp. 56, 57) are the axle shafts. They are splined into the differential’s side gears (Comp. 49) and transmit torque to the wheel hubs. These shafts are designed to flex torsionally to absorb shock loads, protegendo o Eixo traseiro FAW J6P differential from sudden, damaging impacts.

Essencial 4: O “Alinhamento & Pré-carregar” Lógica (Differential Carrier)

This final group is critical for servicing the differential. These components set the alignment and pre-load of the entire differential carrier within the Eixo traseiro FAW J6P habitação.

1. Componente: ‘Tapered roller bearing’ (32216/YA6E) – Quantidade 1
Esse (Comp. 44) is one of the two massive tapered roller bearings that support the entire differential assembly (Comp A). These bearings handle the immense radial load of the vehicle and the axial thrust from the ring gear.

2. Componente: ‘Cover-differential bearing’ (2402019-A0E) & ‘Nut-fastening differential bearing cover’ (2402023-A0E)
Esse (Comp. 51, 52) is the bearing cap and fastener set for the other side of the differential carrier. These caps hold the bearings (Comp. 44) in place and are fundamental to the structural integrity of the Eixo traseiro FAW J6P.

3. Componente: ‘Adjustment shim-differential bearing’ (2403071-A0E) – Quantidade 2
Esse (Comp. 45) is a precision shim. O Lógica de reação está definido aqui. Technicians use these shims to move the entire differential carrier left or right, definindo o padrão preciso de contato dentário (retaliação) between the pinion (Comp 2402010AA6E) and ring gear (Comp. 39). Este ajuste é fundamental para um ambiente tranquilo e duradouro Eixo traseiro FAW J6P.
