Dongfeng xinjiang truck spare parts left side installation bracket assembly 8406619-KXGG01Y

Built to anchor heavy left-side components (fuel tanks up to 380kg, air reservoirs up to 90kg), the bracket 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 Q355 steel by 28% in load resistance. The 10mm-thick main body integrates 12mm-thick triangular reinforcing ribs at stress points (mounting holes, corners), distributing static/dynamic loads evenly across the chassis. Under dynamic conditions (bumps, turns), the bracket maintains maximum deflection ≤1.6mm (full load), preventing component shifting that could damage hoses or electrical connections. This robustness ensures stability during heavy-haul or off-road operations

Engineered for precise left-side component installation, the bracket features a multi-point positioning structure that cuts alignment time by 40%. It includes 2 conical locating pins (15mm diameter, 28mm length) fitting the chassis’s pre-drilled holes, ensuring initial positioning accuracy within ±0.4mm. The component mounting surface has a flatness tolerance of ≤0.2mm/m, ensuring tight contact and eliminating vibration-causing gaps. Four slotted adjustment holes (17mm×11mm) allow ±4mm micro-adjustment, accommodating minor chassis deformation or component variations. Clear “FRONT”/“TOP” marks and part number engraving prevent reverse installation, ensuring correct fitment on the first attempt—critical for left-side weight distribution

Designed to resist corrosion from road salt, moisture, and contaminants, the bracket uses a four-step anti-corrosion process. First, a 12μm zinc phosphate pretreatment forms a rust-inhibiting base. Next, a 20μm electrophoretic primer ensures uniform coverage. Then, an 85-95μm epoxy-polyester powder coating creates a scratch-resistant barrier. Finally, a clear chromate passivation layer enhances chemical resistance. It passes 1800-hour salt spray testing (ASTM B117) with no red rust, suitable for coastal/snowy regions. The bracket withstands -40℃ to 120℃ without coating peeling, adapting to frigid winters and hot deserts. Zinc-plated steel inserts in threaded holes prevent thread rust, ensuring easy disassembly during maintenance

Optimized for fleet maintenance, the bracket combines versatility with user-friendliness. It fits multiple left-side components (fuel tanks, air reservoirs) by replacing adapter plates, reducing inventory costs. The package includes 6 M14×45 grade 10.9 bolts, lock washers, and flat washers, matching OE torque requirements (150-170N·m). Installation needs only a hydraulic torque wrench; two technicians complete it in 40 minutes or less. The 6.5kg lightweight design simplifies handling, while pre-greased locating pins reduce friction. Its modular structure allows replacing damaged reinforcing ribs instead of the entire assembly, further lowering maintenance costs—ideal for fleet efficiency
