FAW J6P Wheel: Déconstruction 17 Critical Parts for Flawless Load-Bearing Operation

This is a complete technical deconstruction of the FAW J6P Wheel and tire assemblies for the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. Ce guide détaille les 17 types de composants réparables, covering two main variants of the FAW J6P Wheel: le 8.8-20 heavy-duty model and the 8.5-20 standard model.

Le FAW J6P Wheel assembly is the foundational component for transferring all vehicle power, braking forces, and load to the ground. For a heavy-duty dump truck, this is not a simple part; it is a multi-piece, high-strength steel assembly designed to withstand extreme impacts, massive payloads, and high torque from the planetary hubs. This deconstruction will analyze the two primary types of FAW J6P Wheel assemblies found on this vehicle: le 8.8-20 Heavy-Duty version (3101015AJ6P) et le 8.5-20 standard version (3101015-93W). We will also break down the common tire, tube, and flap components (12.00R20 18PR) that are critical to the function of every FAW J6P Wheel. Understanding the differences between these serviceable assemblies is essential for correct parts ordering and safe vehicle operation. Un bien entretenu FAW J6P Wheel is a non-negotiable for chassis and drivetrain health.

Cœur 1: Le “Robuste” Logique (3101010AJ6P Assembly)

This group represents the primary heavy-duty FAW J6P Wheel assemblée (Quantité 8), designed for maximum load capacity and durability in severe off-road conditions. This is the main assembly used for the tandem drive axles.

1. Composant: ‘8.8-20 Heavy-duty wheel rim & disc assy’ (3101015AJ6P) – Quantité 8
Ce (Comp 1) is the core of the heavy-duty FAW J6P Wheel. Le 8.8-20 designation indicates a wider, thicker steel rim designed to handle the 12.00R20 18PR tire under extreme payloads. C'est un seul, welded assembly combining the outer rim (where the tire sits) and the inner disc (which bolts to the hub). Le “AJ6P” part number signifies its specific, reinforced design for this J6P dump truck, differentiating it from a standard FAW J6P Wheel.

2. Composant: ‘Elastic lock ring-8.50-20 wheel’ (3101027-J6P) – Quantité 8
Ce (Comp 5) is the specific ‘J6P’ model lock ring for this FAW J6P Wheel. Ce Multi-Piece Rim Logic is standard for heavy-duty trucks. This split steel ring is what locks the tire bead onto the rim. It allows for tire mounting and dismounting in the field with heavy tire irons, which is impossible with a one-piece tubeless rim of this size. This is a critical safety component of the FAW J6P Wheel and must be inspected for wear, rust, or deformation at every tire change, as a failed ring can lead to an explosive disassembly.

Cœur 2: Le “Standard” Logique (3101010-93WJ Assembly)

This group represents the standard FAW J6P Wheel assemblée (Quantité 3), which may be used for the front steer axle or as the spare. It has a slightly different construction, being fully deconstructed in the BOM.

1. Composant: ‘8.5-20 Wheel rim & disc assy’ (3101015-93W) – Quantité 3
Ce (Comp 1, right table) is the standard 8.5-20 FAW J6P Wheel assemblée. This component is broken down further into its constituent, serviceable parts, unlike the heavy-duty model. The ‘8.5-20’ indicates a standard 8.5-inch width, slightly narrower than the 8.8-inch heavy-duty model.

2. Composant: ‘Rim body-8.5-20 wheel’ (3101021-93W) – Quantité 3
Ce (Comp 1 sub-part) is the outer rim hoop itself. This is the part that holds the tire, tube, flap, and lock ring (Comp 5, 3101027-174). This part is serviceable and can be replaced if it becomes bent or cracked.

3. Composant: ‘Wheel disc-8.5-20 wheel’ (3101036-93W) – Quantité 3
Ce (Comp 1 sub-part) is the ‘disc’ or center plate of the FAW J6P Wheel. This is the component with the 10 bolt holes that mounts to the hub. Le Two-Piece Logic here shows that the rim body (Comp 2) and the disc (Comp 3) are manufactured separately and then welded or riveted together to create the final wheel (Comp 1). This is a common manufacturing process for a FAW J6P Wheel, allowing different disc offsets to be paired with a standard rim.

Cœur 3: Le “Pneu & Tube” Logique (The Common Components)

This group of components is common to both types of FAW J6P Wheel assemblages. This is the ‘tube-type’ setup required for heavy-duty, multi-piece rims, as they are not airtight.

1. Composant: ‘Outer tire-12.00R20 18PR’ (3106010A174) – Quantité 11 (Total)
Ce (Comp 2 left, Comp 2 right) is the main tire. Le 12.00R20 designation means it is 12 inches wide for a 20-inch rim, with a Radial construction. Le 18RP (18-ply rating) signifies an extremely strong, high-load-capacity tire, essential for a dump truck. This is the literal footprint of the FAW J6P Wheel.

2. Composant: ‘Inner tube-12.00R20 18PR’ – Quantité 11 (Total)
Ce (Comp 3 left, Comp 3 right) is the inflatable inner tube that holds the compressed air. As this is not a tubeless rim, the tube is a mandatory component for every FAW J6P Wheel. A high-quality, heavy-duty tube is required to match the 18-ply rating of the outer tire.

3. Composant: ‘Flap-12.00R20 18PR’ – Quantité 11 (Total)
Ce (Comp 4 left, Comp 4 right) is a thick rubber ‘flap’ or ‘liner’ that sits inside the rim. Le Tube Protection Logic est critique. This flap protects the inner tube from being chafed or punctured by the steel rim (Comp 1) and the lock ring (Comp 5/5). A missing or damaged flap will cause rapid tube failure in the FAW J6P Wheel.

4. Composant: ‘8.5-20 Valve stem’ (3101016-174) – Quantité 3
Ce (Comp 1 sub-part) is the air valve. It is a serviceable part that attaches to the inner tube and passes through the rim, allowing for inflation. This is a common failure point for the FAW J6P Wheel, as it can be damaged by rocks or debris.

Cœur 4: Le “Dynamic Balancing” Logique (The Balance Weights)

This final group is essential for a smooth, stable ride at speed. An unbalanced FAW J6P Wheel assembly will cause severe vibration, damaging suspension components and causing premature tire wear.

1. Composant: ‘Wheel balance weight assy’ (3101050-174, etc.) – Qty As Req.
Ce (Comp 6 left, Comp 6 right) is a set of ‘As Required’ weights. The BOM lists multiple variants (3101055, 3101060, 3101065, 3101070) which correspond to different gram-weights (Par exemple, 50g, 100g, 150g).

Le Balancing Logic is that after a tire is mounted, l'intégralité FAW J6P Wheel assembly is placed on a dynamic balancing machine. The machine identifies ‘heavy spots’. A technician then clips these lead or steel weights onto the opposite side of the rim flange to counteract the imbalance. This is a critical final step in servicing any FAW J6P Wheel. Given the size and weight of a 12.00R20 tire, significant weight may be required to properly balance the FAW J6P Wheel assemblée.
