FAW J6P Adjustable Footrest: Deconstructing 11 Critical Parts for Ultimate Cab Ergonomics

This is a concise technical deconstruction of the FAW J6P Adjustable Footrest assembly for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck. This guide analyzes the 11 serviceable component types, detailing the mounting hardware, structural arms, and decorative covers that form the complete footrest unit.

The FAW J6P Adjustable Footrest is a crucial ergonomic component designed to enhance driver comfort and safety during long hauls. Its primary function is to provide a stable, comfortable, and adjustable platform for the driver’s left foot. This feature reduces leg fatigue and provides a bracing point for the driver, which is essential for maintaining control and stability on rough terrain or during sudden braking maneuvers.

This deconstruction will analyze the key structural components of the FAW J6P Adjustable Footrest, including the mounting brackets, the pivotable steps, the protective trim, and the heavy-duty fastening system. The robustness of the FAW J6P Adjustable Footrest ensures it can withstand the repetitive force of the driver’s foot without breaking or vibrating loose. Every part of the FAW J6P Adjustable Footrest assembly is designed for long-term comfort and structural integrity.

Core 1: The “Ergonomics” Logic (The Stepping Plates)

This group of components provides the surface for the driver’s foot. The design aims for optimal placement and stability. This is the main tactile part of the FAW J6P Adjustable Footrest.

1. Component: ‘Left secondary footrest plate’ (5103033B50A) & ‘Right secondary footrest plate’ (5103034B50A) – Qty 1 each
This (Comp 5, 6) is the actual stepping surface. The Stepping Surface Logic suggests these are secondary plates, implying the main cab floor acts as the primary resting point. These plates provide the specialized angle and position for the driver’s left foot, which is essential for the ergonomic design of the FAW J6P Adjustable Footrest.

2. Component: ‘Left footrest support arm assy’ (5103225A14B) & ‘Right footrest support arm assy’ (5103230A14B) – Qty 1 each
This (Comp 1, 2) is the structural backbone that mounts the footrest plates (Comp 5, 6) to the cab. The Support Arm Logic ensures this arm provides rigid support, preventing the FAW J6P Adjustable Footrest from flexing or vibrating, which would negate its comfort benefit.

Core 2: The “Fastening” Logic (Structural Security)

This group includes the heavy-duty fasteners responsible for mounting the entire FAW J6P Adjustable Footrest assembly rigidly to the cab structure.

1. Component: ‘Hex head bolt’ (CQ1500870F6) – Qty 4
This (Comp 7) is the primary bolt used to anchor the footrest support arm (Comp 1, 2) to the floor or side panel of the cab. The Anchor Logic dictates these are high-tensile bolts, essential for securing the FAW J6P Adjustable Footrest against accident forces.

2. Component: ‘Spring washer’ (Q40308F6) & ‘Large washer’ (Q40208F6) – Qty 4 each
This (Comp 8, 9) is the anti-vibration hardware. The combination of a ‘Spring washer’ (Comp 8) and a ‘Large washer’ (Comp 9) ensures the bolt head or nut cannot loosen under constant truck vibration, maintaining the rigidity of the FAW J6P Adjustable Footrest structure.

3. Component: ‘Combination bolt’ (CQ1460830F6) – Qty 4
This (Comp 10) is a specialized bolt with a permanently attached washer. This design feature simplifies assembly while ensuring proper load distribution. These bolts are used for securing various secondary mounting points of the FAW J6P Adjustable Footrest to the cab structure.

4. Component: ‘Cross recessed pan head screw assy’ (Q2360612F6) – Qty 8
This (Comp 11) is the bolt used for securing the footrest plates (Comp 5, 6) to the support arms (Comp 1, 2). It is a simpler screw, as this part of the FAW J6P Adjustable Footrest experiences lower stress compared to the main structural anchor points.

Core 3: The “Finishing” Logic (The Decorative Trim)

This group completes the FAW J6P Adjustable Footrest assembly, providing aesthetic finishing and protecting the structural metal from wear and tear.

1. Component: ‘Left footrest decorative trim’ (5103021A14B) & ‘Right footrest decorative trim’ (5103022A14B) – Qty 5 and 6
This (Comp 3, 4) is the plastic or vinyl trim that covers the metal brackets and screws. The Finishing Logic is two-fold: aesthetics (improving the look of the cab interior) and protection (preventing sharp metal edges from snagging the driver’s feet or clothing). The different quantities (5 and 6) indicate a slight asymmetry in the installation process for the FAW J6P Adjustable Footrest.

These decorative pieces are specifically contoured to the shape of the support arms and the cab floor, ensuring a seamless fit and preventing vibration-induced noise. While they do not bear any structural load, they are integral to the aesthetic quality and durability of the FAW J6P Adjustable Footrest. Damage to this trim usually indicates rough usage or potential hidden damage to the underlying metal structure.
