FAW J6P Rear Mudguard: Deconstructing 11 Critical Parts for Flawless Debris Protection

This is a comprehensive guide to the FAW J6P Rear Mudguard assembly for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck. This deconstruction analyzes the 11 serviceable component types, detailing the mounting brackets, structural tubes, and anti-vibration hardware that secure the entire rear fender system.

The FAW J6P Rear Mudguard assembly is essential for vehicle and environmental safety. Its primary function is to prevent mud, rocks, water, and debris kicked up by the tandem rear wheels from impacting the bodywork, windows, and following vehicles. This is achieved through a multi-piece assembly consisting of the main plastic or rubber fender sections and their robust steel mounting structure.

The complexity of the FAW J6P Rear Mudguard lies in its support system, which must be strong enough to withstand severe impacts and constant vibration without fracturing, yet flexible enough not to damage the frame. This deconstruction will analyze the main mudguard sections, the supporting tubes and rods, the specialized mounting brackets, and the specific high-strength hardware used to ensure the security of the **FAW J6P Rear Mudguard** assembly. Every element of the FAW J6P Rear Mudguard contributes to the legal and operational integrity of the dump truck.

Core 1: The “Mudguard” Logic (The Protective Panels)

This group includes the main panels of the FAW J6P Rear Mudguard that provide the actual barrier against road debris. They must be durable yet somewhat flexible.

1. Component: ‘Left rear mudguard’ (5103361-50V) & ‘Right rear mudguard’ (5103362-50V) – Qty 1 each
This (Comp 1, 2) is the main protective panel assembly. The Coverage Logic ensures these panels cover the entire width and circumference of the tandem wheels. They are likely molded from durable, lightweight plastic or composite material to resist impacts while keeping the overall vehicle weight low.

2. Component: ‘Left rear mudguard support tube assy’ (5103365-14B) & ‘Right rear mudguard support rod assy’ (5103370AB35J) – Qty 1 each
This (Comp 3, 4) is the heavy-duty steel tube or rod framework that supports the mudguard panels (Comp 1, 2). The Structural Support Logic ensures that these thin panels remain rigid at high speeds and can resist impacts from large rocks. These structural supports are the true core of the FAW J6P Rear Mudguard.

3. Component: ‘Front wheel anti-spray flap’ (5103411-14B) – Qty 2
This (Comp 6) is a specialized flap positioned ahead of the rear wheels. Its Anti-Spray Logic is designed to catch debris thrown forward by the middle axle before it impacts the rear axle, improving traction and longevity of the tandem axles. This flap is often thick rubber, secured to the FAW J6P Rear Mudguard structure.

Core 2: The “Fastening” Logic (Locking Hardware)

This group of components provides the necessary clamping force and anti-vibration security to attach the FAW J6P Rear Mudguard structure to the vehicle frame.

1. Component: ‘Hex flange bolt (Standard)’ (Q1841455) – Qty 2
This (Comp 7) is a high-tensile bolt used for securing the main support rods (Comp 3, 4) to the FAW J6P Frame. This is a critical structural fastener.

2. Component: ‘Hex flange lock nut’ (CQ32614) – Qty 2
This (Comp 8) is the matching locking nut. The Self-Locking Logic is paramount: this nut contains an anti-vibration feature that prevents it from backing off the bolt, which is essential given the constant vibration and shock loads experienced by the FAW J6P Rear Mudguard system.

3. Component: ‘Combination bolt’ (CQ1420825) – Qty 11
This (Comp 9) is a specialized bolt with an attached washer. Eleven of these are used throughout the assembly for mounting the lighter parts of the FAW J6P Rear Mudguard, such as the panels, to the structural support rods.

4. Component: ‘Hex nut’ (CQ34008) & ‘Large washer’ (Q40208) – Qty 11 each
This (Comp 11, 10) is the standard hardware set used in secondary mounting points. The combination provides clamping force and protection against vibration-induced loosening, ensuring every part of the FAW J6P Rear Mudguard remains secure.

Core 3: The “Sealing & Protection” Logic (Grommets and Plugs)

This group includes the smaller, often overlooked components that ensure the structural supports of the FAW J6P Rear Mudguard are sealed and protected from corrosion.

1. Component: ‘Plug’ (5103363-50A) – Qty 4
This (Comp 5) is a small plug, likely made of rubber or plastic, designed to seal the ends of the tubular support rods (Comp 3, 4). The Corrosion Protection Logic is that these plugs prevent water and debris from entering the hollow metal support tubes, which would otherwise lead to internal rust and structural failure of the FAW J6P Rear Mudguard supports.

2. Component: Structural Integrity
The difference between the ‘Support tube assy’ (Comp 3) and the ‘Support rod assy’ (Comp 4) suggests that one side of the FAW J6P Rear Mudguard may require a slightly heavier gauge or a different mounting geometry due to its proximity to the exhaust or another chassis component. These differences are key to maintaining the vehicle’s original engineering integrity.

The overall effectiveness of the FAW J6P Rear Mudguard hinges on the collective function of the plastic panels, the metal supports, and the precise, anti-vibration fasteners. Each part, no matter how small, plays a critical role in debris containment and safety.
