Welcome to this specialized deconstruction of the Eje central izquierdo FAW J6P, a core component within the CA10TA160M gearbox for the FAW Jiefang CA3250P66K2L1T1E 6×4 camión volcado. This technical guide analyzes the 15 componentes que crean el completo Eje central izquierdo FAW J6P, also known as a countershaft, which is fundamental to the gearbox’s torque-handling capability.
El Eje central izquierdo FAW J6P is one half of a “twin-countershaft” o “dual-countershaft” diseño. This advanced gearbox logic splits the engine’s torque into two paths (left and right shafts). This dramatically reduces the load on each individual gear tooth, allowing the transmission to handle the massive, low-speed torque required by a fully-loaded dump truck.
This group represents the foundation of the Eje central izquierdo FAW J6P. It includes the shaft itself and the various keys used to permanently lock the drive gears onto it, ensuring the entire assembly spins as one solid unit.
1. Componente: ‘Centre shaft’ (1701211-A7G)
Este (compensación 3) is the ‘Centre shaft’ sí mismo, the spine of the assembly. It is a single, heavy-duty shaft, precision-machined and forged from hardened steel to be extremely rigid and resistant to torsional (retortijón) forces.
El Torque Splitting Logic is its core purpose. As the Eje central izquierdo FAW J6P, it runs parallel to the mainshaft and an identical “Right Centre Shaft.” It receives approximately 50% of the power from the input shaft gear and is in constant, permanent mesh with the “driven” gears on the mainshaft.
2. El “Llave” Grupo (compensación 4, 5, 6)
Este grupo incluye: ‘Woodruff key’ (compensación 4), ‘Spring cylindrical pin’ (compensación 5), and ‘Flat key’ (compensación 6). These are all “locating keys” used to fix the gears to the Eje central izquierdo FAW J6P.
El Lógica de bloqueo es su funcion. The drive gears (like Comp 7, 8, 9) are not “free-spinning”; they must be rigidly locked to the Eje central izquierdo FAW J6P. A ‘Woodruff key’ (compensación 4) is a half-moon shaped key that sits in a crescent-shaped slot, locking a gear hub in place. A ‘Flat key’ (compensación 6) es un simple, strong key for a straight slot. A ‘Spring pin’ (compensación 5) is a vibration-proof pin, likely used to secure a gear collar.
This is the primary “laboral” parte del Eje central izquierdo FAW J6P. These are the fixed gears that provide the “drive” torque to the mainshaft’s “driven” engranajes.
1. El “Main Gears” (compensación 7, 8, 9)
Este grupo incluye: ‘Second gear – centre shaft’ (compensación 7), ‘Third gear – centre shaft’ (compensación 8), and ‘Fourth gear – centre shaft’ (compensación 9). Nota: In this design, “First gear” y “Contrarrestar” are often handled by the ‘Reduction gear’ or a separate idler, not this main stack.
El Constant Mesh Logic es clave. Unlike the mainshaft gears (which spin freely), all gears on the Eje central izquierdo FAW J6P are *fixed* to the shaft (P.EJ., by the keys in Core 1). They spin as one single, solid unit.
This means when the engine turns the Eje central izquierdo FAW J6P, all these gears (2Dakota del Norte, 3rd, 4th) are spinning at the same RPM. The driver selects a gear by locking the corresponding “driven” engranaje (on the mainshaft) to the mainshaft, which completes the power path for that specific ratio.
2. Componente: ‘Reduction gear – centre shaft’ (1701217-A7G)
Este (compensación 11) is the ‘Reduction gear’. This is likely the main “aporte” gear of the Eje central izquierdo FAW J6P, which meshes with the ‘First Axis’ (eje de entrada) engranaje.
Es Reduction Logic is to provide the first, main gear reduction in the entire gearbox. It multiplies the torque *before* it even gets to the 2nd/3rd/4th gears, providing the massive “grunt” o “pulling power” needed for a dump truck. It is secured on the shaft by its own ‘Snap ring’ (compensación 12).
This component’s logic is to provide a “tap” o “take-off” point for the engine’s power, allowing it to run auxiliary equipment, which is essential for a dump truck.
1. Componente: ‘PTO gear – centre shaft’ (1701246-A7G)
Este (compensación 10) is the ‘Power Take-Off Gear’. This gear is also fixed to the Eje central izquierdo FAW J6P and spins constantly with it (anytime the clutch is engaged).
El Hydraulic Logic is its application. This gear (compensación 10) is what meshes with the idler gear of the PTO unit (which is bolted to the side of the gearbox housing). When the driver engages the PTO, this gear transmits the engine’s power *out* of the gearbox to run the hydraulic pump for the dump body.
Its position on the Eje central izquierdo FAW J6P es critico. Because this shaft spins whenever the clutch is engaged (even when the main gearbox is in neutral), it allows the dump truck to be stationary but still use the engine’s power to run the hydraulic pump and raise the dump bed.
This final group is responsible for supporting the entire Eje central izquierdo FAW J6P asamblea, holding it in its precise location and allowing it to spin smoothly under immense radial and axial loads.
1. El “Cojinete” Grupo (compensación 2, 13)
Esto incluye: ‘Cylindrical roller bearing’ (compensación 2) and ‘Cylindrical roller bearing with stop ring’ (compensación 13). These are the main bearings for the Eje central izquierdo FAW J6P, supporting it at the front and rear of the gearbox case.
El Roller Bearing Logic is used for its superior strength. Unlike ball bearings, roller bearings have a larger contact patch, making them ideal for handling the extremely high *radial* loads (el “emprendedor” force between gears) inside a heavy-duty gearbox. The ‘stop ring’ on Comp 13 is a snap ring on the *outer* race, cual “locates” the bearing in the housing bore.
2. El “Retención” Grupo (compensación 1, 12, 14, 15)
Este grupo incluye: 'Anillo de presión – centre shaft rear bearing’ (compensación 1), 'Anillo de presión – reduction gear’ (compensación 12), ‘Baffle plate – centre shaft front bearing’ (compensación 14), and ‘Hexagon head bolt with guide neck’ (compensación 15).
El Axial Control Logic es su funcion. The ‘Snap rings’ (compensación 1, 12) fit into grooves on the Eje central izquierdo FAW J6P itself to lock bearings or gears (like the ‘Reduction gear’, compensación 11) en su lugar, preventing any “axial” (in-and-out) movimiento.
El Baffle Plate Logic (compensación 14) es critico. This plate, held by the ‘Hexagon head bolt’ (compensación 15), acts as a “retainer” for the front bearing (compensación 13). It also functions as an “oil slinger” o “baffle,” directing lubricating oil into the bearing race while also preventing excessive “splash” from reaching the front seal. This entire group ensures the Eje central izquierdo FAW J6P stays perfectly positioned.
