FAW J6P Handle: Deconstructing 8 Critical Parts for Flawless Door Access

Welcome to this definitive guide on the FAW J6P Handle and access system for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck. This deconstruction analyzes the 8 critical component types, focusing on the inner and outer handles. These assemblies are the primary driver interface for cab access and egress.

The FAW J6P Handle system is a robust, electro-mechanical assembly designed for extreme durability. On a heavy-duty truck, the handles must endure hundreds of thousands of pull cycles, severe vibration, and contamination from mud, ice, and dust. This analysis will deconstruct the outer and inner handles, their critical link to the electric lock body, and the vibration-proof fasteners that secure them.

Core 1: The ‘Exterior Access’ Logic (The Outer Handle)

This component group is the primary external interface of the FAW J6P Handle system. It is engineered for heavy-duty use in all weather conditions, providing the first point of mechanical actuation for the door.

1. Component: ‘Left/Right front door outer handle assembly’ (6105105-A01 / 6105110-A01) – Qty 1 each
These (Comp 2) are the mirrored, symmetrical outer handles. The “assembly” designation means they are pre-built units that include the pull handle, the pivot mechanism, the exterior bezel, and the internal lever that connects to the lock body.

The Actuation Logic is its main purpose. When a user pulls this FAW J6P Handle, a robust internal lever is pivoted. This lever pulls a connecting rod (not listed, part of door) which in turn actuates the “release” lever on the core lock mechanism (Comp 4). This is a purely mechanical linkage, ensuring it works even if the truck’s battery is dead.

The Durability Logic is critical for a dump truck. These handles are manufactured from high-impact, UV-stabilized polymer composites. This prevents them from becoming brittle in sub-zero temperatures or fading and cracking under constant sun exposure. The oversized “pull” design is deliberate, allowing easy use by an operator wearing heavy work gloves.

The Security Logic is also integrated. This assembly houses the physical key cylinder, which provides the mechanical “key” override for the electric lock. This makes the FAW J6P Handle assembly the hub for both keyed and keyless entry.

2. Component: ‘Cross recessed flat round head combination screw’ (Q2360612F6) – Qty 4
These (Comp 3) are the four fasteners—two for each outer handle—that secure the assembly to the door shell. They are “combination” screws, meaning they have a pre-installed, captive spring lock washer. This is essential to prevent the handle from vibrating loose from door slams.

Core 2: The ‘Interior Egress’ Logic (The Inner Handle)

This component group is the critical safety-of-life part of the FAW J6P Handle system. It ensures a driver can exit the cab from the inside under all conditions.

1. Component: ‘Left/Right front door inner handle assembly’ (6105075-B27-C00 / 6105080-B27-C00) – Qty 1 each
These (Comp 7) are the left and right interior handles. The ‘B27-C00’ suffix indicates they are complete assemblies including the lever, the pivot, and the surrounding bezel, likely specified to match the cab’s interior trim color and texture.

The Safety Logic is their sole function. This FAW J6P Handle provides a 100% mechanical override for the door latch. Pulling this lever actuates a separate linkage (rod or cable) that connects to the core lock body (Comp 4).

This linkage is designed to “pop” the latch open, even if the door is electrically locked. This is a fundamental safety requirement, ensuring a driver can escape in an emergency, even after an accident that has cut electrical power.

The Design Logic is focused on reliability and ergonomics. The low-profile lever design prevents it from being accidentally snagged by clothing or equipment, which could inadvertently open the door. It is designed to be failsafe and reliable for the life of the truck.

2. Component: ‘Cross recessed flat round head combination screw’ (Q2360612) – Qty 6
These (Comp 8) are the six fasteners—three for each inner handle—that secure the assembly to the interior door panel. Like the outer handle’s screws, these are “combination” screws with integrated locking washers to prevent loosening from vibration.

Core 3: The ‘Associated Actuator’ Logic (The Lock Body)

While the handles are the interface, this component is the “brain.” The FAW J6P Handle system is entirely dependent on this core lock body, which receives the mechanical inputs from the handles.

1. Component: ‘Left/Right front door electric lock body assembly’ (6105025AA01 / 6105030AA01) – Qty 1 each
This (Comp 4) is the central hub that both the inner and outer FAW J6P Handle components connect to. It is a sealed, electro-mechanical unit that contains the physical latch mechanism and a 12V motor (actuator) for the central locking.

The Linkage Logic is how it interacts with the handles. The lock body has multiple, distinct levers. One lever accepts the input from the outer handle (Comp 2). A separate, redundant lever accepts the input from the inner handle (Comp 7). This ensures that a failure in one linkage (e.g., a broken outer handle) does not compromise the other (the inner handle).

This assembly is the “heavy lifter” of the system. It contains the high-strength steel “claw” that latches onto the cab’s striker, and it is built to withstand massive door-slam forces.

2. Component: ‘Cross recessed countersunk head screw’ (Q2540612F6) & ‘Multi-tooth conical elastic washer’ (Q41406F6) – Qty 6 sets
These (Comp 5 and 6) are the high-strength fasteners for the lock body. The countersunk head sits flush in the door edge. The “multi-tooth” washer is a specialized, extreme-vibration lock washer that bites into the metal, ensuring this critical component *never* loosens.

Core 4: The ‘Foundation’ Logic (The Door Shell)

Finally, the entire FAW J6P Handle system is mounted to the door shell itself. This component is the foundation for all other parts in this assembly.

1. Component: ‘Left/Right front door weld assembly’ (6100055-B35 / 6100060-B35) – Qty 1 each
This (Comp 1) is the parent structure. It is the complete, welded-together door “body-in-white,” including the outer skin and the inner structural frame.

The Structural Logic is that this assembly is precisely stamped with all the necessary holes, recesses, and mounting bosses to accept the FAW J6P Handle components (inner and outer) and the lock body.

The inner frame is hollow, allowing the connecting rods and wiring harnesses to be routed between the handles and the lock body, protecting them from damage. The strength of this weld assembly is what provides the rigid backing needed for the latches and hinges to function properly without flexing or misalignment.
