Subgabinete FAW J6P: Desconstruindo 22 Peças críticas para integridade impecável do sistema de transmissão

Bem-vindo a esta análise especializada do Subgabinete FAW J6P, the foundational housing for the CA10TA160M auxiliary gearbox. This component is essential for the FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. Este guia analisa o 22 part types that seal, apoiar, and complete the Subgabinete FAW J6P (with PTO) for professional service.

O Subgabinete FAW J6P é o “chassis” of the 10-speed transmission’s range box. Its logic is to provide a perfect, rigid alignment for the high-torque auxiliary countershafts and the main spindle. It also contains the oil and provides the mounting point for the critical Power Take-Off (PTO) unidade.

Essencial 1: O “Estrutural” Lógica (The FAW J6P Sub-Enclosure & PTO)

This group contains the main structural casting, o “chassis” of the auxiliary gearbox, and the lifting lug used to service it. O Subgabinete FAW J6P is the literal foundation.

1. Componente: ‘Sub-box housing’ (1701501AA1K)
Esse (Comp. 2) é o Subgabinete FAW J6P em si. Este é um enorme, complex component, precision-cast from high-strength iron or aluminum. Its logic is threefold: alinhamento, vedação, and heat dissipation.

O Lógica de Alinhamento é a sua função mais crítica. This main case has multiple, perfectly parallel bores machined into it to hold the bearings for the ‘Sub-Box Spindle’ and the various countershafts (like the ‘Left Upper’ and ‘Right Lower’ shafts). Any warping or damage to the Subgabinete FAW J6P will cause shaft misalignment, leading to rapid gear and bearing failure.

O Lógica de Selagem is its obvious function. Funciona como um grande “reservatório” ou “oil bath” for the auxiliary gear set. It is designed with multiple machined faces for gaskets (como Comp. 1, 7, 21) to create a leak-proof enclosure.

O PTO Port Logic is its special feature. A nota “(带取力器)” (with PTO) on the diagram title confirms this Subgabinete FAW J6P is cast with a standardized 6-bolt or 8-bolt “janela” ou “aperture” on the side. This port is designed to mount the truck’s hydraulic pump PTO, allowing the gearbox to power the dump body.

2. Componente: ‘Lifting lug’ (1702096-A7G)
Esse (Comp. 18) is a heavy-duty steel bracket bolted to the top of the Subgabinete FAW J6P (using bolts Comp 19).

O Lógica de serviço é a sua função. A complete transmission assembly is extremely heavy. This ‘Lifting lug’ fornece um seguro, balanced attachment point for an engine hoist or chain, allowing technicians to safely remove and install the entire gearbox from the truck’s chassis.

Essencial 2: O “Output Shaft Seal” Lógica (Spindle Interface)

This group is dedicated to sealing the largest, most critical rotating component of the Subgabinete FAW J6P: the final output shaft (spindle).

1. Componente: ‘Rear bearing cover – sub-box output shaft’ (1701586-A7K)
Esse (Comp. 8) is the main bearing retainer for the ‘Sub-Box Spindle’. É um grande, cast cover that bolts to the very back of the Subgabinete FAW J6P (using bolts Comp 16).

O Lógica de pré-carga de rolamento is this cover’s primary job. Isto “traps” the outer race of the ‘Double-row tapered roller bearing’ (from the Spindle assembly). A ‘junta – eixo de saída’ (Comp. 7) sits between this cover and the main housing, and its thickness is critical for setting the spindle’s bearing pre-load.

2. Componente: 'Conjunto de vedação de óleo’ (1701605-A7G)
Esse (Comp. 15) is the main output shaft oil seal. It is pressed *into* the ‘Rear bearing cover’ (Comp. 8).

O Lógica de Selagem is this component’s “no-fail” função. It is the final, dynamic seal of the entire drivetrain. Its flexible lip rides on the spinning ‘Output flange’ (from the Spindle assembly). Its logic is to keep 100% of the gear oil *inside* the Subgabinete FAW J6P while keeping 100% of road dirt, água, e detritos *fora*. A failure here results in a major, high-speed oil leak.

Essencial 3: O “Countershaft Pre-load” Lógica (The Shim Stack)

This group contains the hardware for sealing and, o mais importante, setting the pre-load for the auxiliary countershafts (like the ‘Left Upper’ and ‘Right Lower’ shafts) as they mount into the Subgabinete FAW J6P.

1. Componente: ‘Rear bearing cover – sub-box intermediate shaft’ (1701521-A7G)
Esse (Comp. 20) is the bearing retainer for one of the countershafts. It is a cover that bolts to the Subgabinete FAW J6P, “trapping” the outer race of the shaft’s tapered roller bearing.

2. Componente: 'Junta – sub-box intermediate shaft’ (1701523-A7G)
Esse (Comp. 21) is the paper or cork gasket that seals the ‘Bearing cover’ (Comp. 20) para o Subgabinete FAW J6P, preventing oil leaks from the bearing bore.

3. Componente: ‘Adjusting gasket (shim) – sub-box intermediate shaft’ (Comp. 22)
Esse (Comp. 22) represents a large set of ‘Adjusting gaskets’, ou “calços,” of various, precisely-controlled thicknesses (Por exemplo, 1701526-A7G, 1701527-A7G, etc.). They are listed as “As required.”

O Pre-load Logic is the most high-precision task in servicing the Subgabinete FAW J6P. Tapered roller bearings on the countershafts require a specific “pré-carregamento” (espremer) funcionar. A technician assembles the shaft, measures the “fim do jogo” with a dial indicator, and then selects *one* shim (or a stack) from this group.

This shim (Comp. 22) is placed *between* the ‘Bearing cover’ (Comp. 20) and the ‘Gasket’ (Comp. 21). Its exact thickness is what “sets” the bearing pre-load. Using the wrong shim will cause the bearing to fail very quickly. Isso faz com que Subgabinete FAW J6P a high-precision item to service.

Essencial 4: O “Speedometer & Fixador” Lógica (All Hardware)

This final group includes all the miscellaneous hardware that completes the Subgabinete FAW J6P conjunto, from the speedometer drive to the myriad of fasteners.

1. O “Speedometer” Grupo (Comp. 9, 10, 11, 12, 13, 14)
This is the complete assembly for the mechanical speedometer drive. It includes the ‘Lever – for speedometer drive’ (Comp. 9), the ‘Joint – speedometer flexible shaft’ (Comp. 11), a ‘Fastening screw’ (Comp. 14), and ‘O-ring seals’ (Comp. 10, 12) with a ‘Spring washer’ (Comp. 13) for the screw.

O Drive Logic is how the truck’s dashboard gets its speed reading. A plastic “speedo gear” (on the Sub-Box Spindle) spins the ‘Lever’ (Comp. 9). This ‘Lever’ (or drive gear) is housed in the ‘Joint’ (Comp. 11), which is a 90-degree adapter that bolts to the Subgabinete FAW J6P. The truck’s flexible speedometer cable then screws onto this ‘Joint’.

O Lógica de Selagem for this sub-assembly is the job of the two ‘O-ring rubber seals’ (Comp. 10 e 12). These are critical for preventing gear oil from wicking up the speedometer drive and leaking out of the Subgabinete FAW J6P.

2. O “Fixador & Selagem” Grupo (Todos os outros)
This group contains all the hardware (Comp. 1, 3, 4, 5, 6, 16, 17, 19) que detém o Subgabinete FAW J6P junto.

O Lógica do Fixador includes a large assortment of high-tensile bolts: ‘Hexagon head bolt with guide neck’ (Comp. 4, 5, 6) and ‘Hexagon flange bolt’ (Comp. 16, 17, 19). O “guide neck” bolts are for high-precision alignment of bearing covers. O “mesa” bolts have a built-in washer to resist vibration.

O Lógica de Selagem is provided by ‘Gasket’ (Comp. 1), 'Junta – eixo de saída’ (Comp. 7), and the ‘Spring washers’ (Comp. 3). The gaskets provide the “static seal” between flat, metal surfaces. O 19 ‘Arruelas de pressão’ (Comp. 3) are the primary “antivibração” lógica, providing constant tension on the bolts to prevent them from backing out and causing a catastrophic oil leak or misalignment of the Subgabinete FAW J6P.
