Dongfeng xinjiang truck parts Right side installation bracket assembly 8406620-KXGG01Y

Built to securely anchor heavy right-side components (fuel tanks up to 400kg, DEF tanks up to 100kg), the bracket assembly delivers exceptional load-bearing performance. It is fabricated from high-strength low-alloy steel (Q460 grade) with a minimum yield strength of 460MPa and tensile strength of 550-670MPa—outperforming standard Q355 steel by 30% in load resistance. The main body (10mm thick) integrates 12mm-thick trapezoidal reinforcing ribs at stress points (mounting hole edges, bracket corners), which distribute static and dynamic loads evenly across the chassis. Under dynamic road conditions (bumps, turns), the bracket maintains maximum deflection ≤1.8mm (at full load), preventing component shifting that could damage hoses or electrical connections. This robust design ensures stability even during heavy-haul or off-road operations

Engineered for precise component installation, the bracket assembly features a multi-point positioning structure that reduces alignment time by 40%. It includes 2 conical locating pins (diameter 16mm, length 30mm) that fit into the chassis’s pre-drilled holes, ensuring initial positioning accuracy within ±0.5mm. The component mounting surface is machined to a flatness tolerance of ≤0.2mm/m, ensuring tight contact with the mounted component and eliminating gaps that cause vibration. Four slotted adjustment holes (18mm×12mm) allow micro-adjustment (±5mm) of component position, accommodating minor chassis deformation or component dimensional variations. Clear alignment marks (“FRONT” and “TOP”) and part number engraving prevent reverse installation, ensuring the bracket functions as intended on the first attempt

Designed to resist corrosion from road salt, moisture, and industrial contaminants—major threats to undercarriage components—the bracket features a comprehensive four-step anti-corrosion process. First, a zinc phosphate pretreatment (12μm) forms a rust-inhibiting base. Then, an electrophoretic primer (20μm) provides uniform coverage. Next, a high-temperature electrostatic powder coating (85-95μm, epoxy-polyester composite) creates a scratch-resistant barrier. Finally, a clear chromate passivation layer enhances chemical resistance. The bracket passes 1800-hour salt spray testing (ASTM B117) with no red rust, suitable for coastal areas and snowy regions. It also withstands extreme temperatures (-40℃ to 120℃) without coating peeling, maintaining performance in frigid winters and hot deserts. All threaded holes are equipped with zinc-plated steel inserts to prevent thread rust

Optimized for efficient fleet maintenance, the bracket assembly combines versatility with user-friendly installation. It is compatible with multiple right-side components (fuel tanks, DEF tanks, toolboxes) by replacing only the adapter plates, reducing inventory costs for fleet operators. The package includes 6 M14×45 high-strength bolts (grade 10.9), lock washers, and flat washers—matching OE torque requirements (160-180N·m). Installation requires only a hydraulic torque wrench; two technicians can complete the process in 45 minutes or less. The bracket’s lightweight design (6.8kg) simplifies handling, while the pre-greased locating pins reduce friction during installation. Additionally, the bracket’s modular structure allows easy replacement of individual reinforcing ribs if damaged, rather than the entire assembly, further lowering maintenance costs
