FAW J6P Front Lock: Deconstructing 7 Critical Parts for Flawless Panel Security

This is a comprehensive technical guide to the FAW J6P Front Lock mechanism for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck. This deconstruction analyzes the 7 serviceable component types, detailing the main lock body, the remote release handle and cable, and the associated mounting hardware that form this critical safety system.

The FAW J6P Front Lock is an essential assembly on the J6P’s cab-over-engine design. Its primary function is to securely fasten the large, heavy front enclosure panel (grille) to the cab body. This mechanism must perform two opposing, safety-critical functions: it must remain rigidly locked against extreme vibration, wind force, and chassis flex, yet it must release instantly and reliably via a remote cable when the driver needs to perform daily fluid checks (oil, coolant).

This deconstruction will analyze the key serviceable components of the FAW J6P Front Lock system. This includes the main ‘Lock body assy’ (the latch), the ‘Lock pin assy’ (the striker), the driver-operated ‘Opening handle’, and the ‘Cable assy’ that connects them. A properly functioning FAW J6P Front Lock is not just a convenience; it is a safety requirement to prevent the front panel from detaching at speed. We will explore every part of this FAW J6P Front Lock mechanism.

Core 1: The “Latching” Logic (The Lock & Pin)

This group of components forms the primary security mechanism of the FAW J6P Front Lock. This is the mechanical interface that physically secures the front enclosure panel.

1. Component: ‘Lock body assy – front enclosure’ (5302510-A01) – Qty 2
This (Comp 1) is the main latch mechanism, used in a pair for redundancy and stability. The Rotary Latch Logic is a robust design: when the ‘Lock pin’ (Comp 3) enters, it forces a rotary pawl (cam) to turn and lock behind it. This pawl is held in place by a spring, ensuring the FAW J6P Front Lock cannot be shaken open by vibration. This assembly is mounted to the cab structure.

2. Component: ‘Lock pin assy – front enclosure’ (5302540-A01) – Qty 2
This (Comp 3) is the “striker” or pin. It is mounted on the moving front enclosure panel. This hardened steel pin is designed to align perfectly with the ‘Lock body’ (Comp 1). The Alignment Logic is critical; this pin must guide the heavy panel into the exact closed position. Misalignment of this FAW J6P Front Lock component will cause the panel to be difficult to close or to rattle.

The interaction between these two parts is the core of the FAW J6P Front Lock. The system is designed to be “self-cinching,” meaning as the lock engages, it pulls the panel tightly against the cab seals, preventing water and dust ingress. Maintenance requires periodic lubrication to prevent the internal pawl from seizing.

Core 2: The “Release” Logic (The Handle & Cable)

This group of components provides the driver with a remote, in-cab method of actuating the FAW J6P Front Lock to gain access to the engine service bay.

1. Component: ‘Opening handle assy’ (5302530-A01) – Qty 1
This (Comp 4) is the driver’s interface, typically located inside the cab near the steering column or in the footwell. The Ergonomic Logic requires this handle to provide enough mechanical leverage for the driver to easily pull and release the ‘Cable assy’ (Comp 6). This handle is a serviceable part of the FAW J6P Front Lock system.

2. Component: ‘Cable assy’ (5302550-A01) – Qty 1
This (Comp 6) is the mechanical link. The Tensile Logic is that this cable (a steel wire inside a protective sheath) must transmit a pulling force from the handle (Comp 4) to the release levers on the ‘Lock bodies’ (Comp 1). The cable must be routed precisely to avoid sharp bends, which would increase friction and cause the cable to stretch or snap.

A common failure mode for the FAW J6P Front Lock is cable failure, either through stretching (which prevents the lock from fully disengaging) or snapping. The ‘Tie strap clamp II’ (Comp 7) is essential for securing this cable to the chassis, preventing it from chafing on metal edges or kinking.

Core 3: The “Mounting & Fastening” Logic (Hardware)

This final group includes the hardware used to secure the various components of the FAW J6P Front Lock system to the cab body and front panel.

1. Component: ‘Combination bolt’ (CQ1460820F6) – Qty 4
This (Comp 2) is a specialized bolt with a captive washer, used to mount the main ‘Lock body assy’ (Comp 1) to the cab structure. The Structural Logic requires these bolts to have high shear strength to withstand the inertia of the heavy front panel during a frontal impact.

2. Component: ‘Cross recessed pan head screw’ (Q2140620F6) – Qty 2
This (Comp 5) is a smaller screw, likely used to mount the ‘Opening handle assy’ (Comp 4) inside the cab, where the loads are purely mechanical and non-structural.

3. Component: ‘Tie strap clamp II’ (3724012-A01) – Qty 6
This (Comp 7) is a critical routing component. Six of these clamps are used to secure the ‘Cable assy’ (Comp 6) along its path from the cab to the front locks. The Chafing Prevention Logic is vital. If the cable sheath is allowed to rub against the metal frame, it will wear through, allowing water to enter. This will corrode the inner cable, causing it to seize and disabling the entire FAW J6P Front Lock. Proper routing with these clamps is a key part of a successful FAW J6P Front Lock installation.
