Дополнительный корпус FAW J6P: Деконструкция 22 Важные детали для безупречной целостности трансмиссии

Welcome to this expert analysis of the Дополнительный корпус FAW J6P, the foundational housing for the CA10TA160M auxiliary gearbox. This component is essential for the FAW Jiefang CA3250P66K2L1T1E 6×4 самосвал. В этом руководстве анализируются 22 part types that seal, поддерживать, and complete the Дополнительный корпус FAW J6P (with PTO) for professional service.

The Дополнительный корпус FAW J6P это “шасси” 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 (ВОМ) единица.

Основной 1: The “Структурный” Логика (The FAW J6P Sub-Enclosure & ВОМ)

This group contains the main structural casting, а “шасси” of the auxiliary gearbox, and the lifting lug used to service it. The Дополнительный корпус FAW J6P is the literal foundation.

1. Компонент: ‘Sub-box housing’ (1701501AA1K)
Этот (Комп 2) это Дополнительный корпус FAW J6P сам. Это масштабное, сложный компонент, precision-cast from high-strength iron or aluminum. Его логика тройственна.: выравнивание, уплотнение, and heat dissipation.

The Логика выравнивания это его самая важная функция. 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 Дополнительный корпус FAW J6P will cause shaft misalignment, leading to rapid gear and bearing failure.

The Логика уплотнения is its obvious function. It acts as a large “отстойник” или “oil bath” for the auxiliary gear set. It is designed with multiple machined faces for gaskets (как Комп 1, 7, 21) to create a leak-proof enclosure.

The PTO Port Logic is its special feature. Примечание “(带取力器)” (with PTO) on the diagram title confirms this Дополнительный корпус FAW J6P is cast with a standardized 6-bolt or 8-bolt “окно” или “апертура” on the side. This port is designed to mount the truck’s hydraulic pump PTO, allowing the gearbox to power the dump body.

2. Компонент: «Подъемная проушина’ (1702096-A7G)
Этот (Комп 18) is a heavy-duty steel bracket bolted to the top of the Дополнительный корпус FAW J6P (с помощью болтов Комп. 19).

The Сервисная логика это его функция. A complete transmission assembly is extremely heavy. This ‘Lifting lug’ обеспечивает безопасную, balanced attachment point for an engine hoist or chain, allowing technicians to safely remove and install the entire gearbox from the truck’s chassis.

Основной 2: The “Output Shaft Seal” Логика (Spindle Interface)

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

1. Компонент: ‘Rear bearing cover – sub-box output shaft’ (1701586-A7K)
Этот (Комп 8) is the main bearing retainer for the ‘Sub-Box Spindle’. Это большой, cast cover that bolts to the very back of the Дополнительный корпус FAW J6P (с помощью болтов Комп. 16).

The Bearing Pre-load Logic is this cover’s primary job. Это “traps” the outer race of the ‘Double-row tapered roller bearing’ (from the Spindle assembly). «Прокладка» – выходной вал’ (Комп 7) sits between this cover and the main housing, and its thickness is critical for setting the spindle’s bearing pre-load.

2. Компонент: ‘Oil seal assy’ (1701605-A7G)
Этот (Комп 15) is the main output shaft oil seal. It is pressed *into* the ‘Rear bearing cover’ (Комп 8).

The Логика уплотнения is this component’s “no-fail” функция. Это финал, 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 Дополнительный корпус FAW J6P while keeping 100% of road dirt, вода, and debris *out*. A failure here results in a major, high-speed oil leak.

Основной 3: The “Countershaft Pre-load” Логика (The Shim Stack)

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

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

2. Компонент: «Прокладка – sub-box intermediate shaft’ (1701523-A7G)
Этот (Комп 21) is the paper or cork gasket that seals the ‘Bearing cover’ (Комп 20) к Дополнительный корпус FAW J6P, preventing oil leaks from the bearing bore.

3. Компонент: ‘Adjusting gasket (прокладка) – sub-box intermediate shaft’ (Комп 22)
Этот (Комп 22) represents a large set of ‘Adjusting gaskets’, или “прокладки,” of various, precisely-controlled thicknesses (НАПРИМЕР., 1701526-A7G, 1701527-A7G, и т. д.). They are listed as “As required.”

The Pre-load Logic is the most high-precision task in servicing the Дополнительный корпус FAW J6P. Tapered roller bearings on the countershafts require a specific “предварительная загрузка” (squeeze) функционировать. A technician assembles the shaft, measures the “end play” with a dial indicator, and then selects *one* shim (or a stack) from this group.

This shim (Комп 22) is placed *between* the ‘Bearing cover’ (Комп 20) and the ‘Gasket’ (Комп 21). Its exact thickness is what “наборы” the bearing pre-load. Using the wrong shim will cause the bearing to fail very quickly. Это делает Дополнительный корпус FAW J6P a high-precision item to service.

Основной 4: The “Спидометр & Застежка” Логика (Все оборудование)

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

1. The “Спидометр” Группа (Комп 9, 10, 11, 12, 13, 14)
This is the complete assembly for the mechanical speedometer drive. It includes the ‘Lever – for speedometer drive’ (Комп 9), the ‘Joint – speedometer flexible shaft’ (Комп 11), a ‘Fastening screw’ (Комп 14), and ‘O-ring seals’ (Комп 10, 12) с пружинной шайбой’ (Комп 13) for the screw.

The Логика привода is how the truck’s dashboard gets its speed reading. A plastic “speedo gear” (на шпинделе дополнительного блока) spins the ‘Lever’ (Комп 9). This ‘Lever’ (or drive gear) is housed in the ‘Joint’ (Комп 11), which is a 90-degree adapter that bolts to the Дополнительный корпус FAW J6P. The truck’s flexible speedometer cable then screws onto this ‘Joint’.

The Логика уплотнения for this sub-assembly is the job of the two ‘O-ring rubber seals’ (Комп 10 и 12). These are critical for preventing gear oil from wicking up the speedometer drive and leaking out of the Дополнительный корпус FAW J6P.

2. The “Застежка & Уплотнение” Группа (Все остальные)
This group contains all the hardware (Комп 1, 3, 4, 5, 6, 16, 17, 19) который держит Дополнительный корпус FAW J6P вместе.

The Логика крепления includes a large assortment of high-tensile bolts: ‘Hexagon head bolt with guide neck’ (Комп 4, 5, 6) и «Болт с шестигранным фланцем’ (Комп 16, 17, 19). The “направляющая шейка” bolts are for high-precision alignment of bearing covers. The “фланец” bolts have a built-in washer to resist vibration.

The Логика уплотнения is provided by ‘Gasket’ (Комп 1), «Прокладка – выходной вал’ (Комп 7), and the ‘Spring washers’ (Комп 3). The gaskets provide the “статическое уплотнение” between flat, metal surfaces. The 19 ‘Spring washers’ (Комп 3) are the primary “антивибрационный” логика, providing constant tension on the bolts to prevent them from backing out and causing a catastrophic oil leak or misalignment of the Дополнительный корпус FAW J6P.
