The Shacman X5000 Welding Assembly Of Bumper Upper Frame is the upper structural backbone of the front bumper system. It connects the left and right bumper support frames and carries the grille, license plate, and upper bumper cover.
Original upper frames often corrode internally or bend in minor collisions, leading to misaligned grilles and bumper gaps. This kit replaces the entire assembly, including all weld‑on fasteners.
The kit contains the main beam, left/right connecting plates, two grille brackets, two license plate brackets, four projection welding bolts, and six square nuts. All components are pre‑treated for corrosion resistance.
Welding is required for the projection bolts and square nuts, but the connecting plates are ready to weld onto the main beam. For shops with resistance welding equipment, this restores the frame to like‑new condition.
Main beam: rectangular hollow section 60x60x3mm, steel grade S420MC, length 1520mm. Weight 8.5 kg. Powder coated black, thickness 60‑80µm. Tolerances: ±1.5mm on length, ±0.5mm on hole positions.
Left and right connecting plates: laser‑cut from 3mm DC01 steel, zinc flake coated (Geomet 500). Hole pattern matches chassis support frames. Each plate includes two M10 weld nuts pre‑installed.
Grille brackets: stamped 2mm steel with e‑coat. Include rubber dampers to prevent grille vibration. Adjustable in height by 10mm via slotted holes.
License plate brackets: 2mm steel, powder coated black. Have two 6.5mm holes each, with 115mm spacing (adjustable). Rubber backing pads included.
Face projection welding bolts (Q1980820): M8x20mm, class 8.8, with three annular projection rings. Designed for capacitor discharge welding onto flat steel surfaces. Required welding current 8‑12 kA, electrode force 2.5 kN. Pre‑coated with anti‑spatter compound.
Welding square nuts (Q37106): M8, class 8, zinc‑plated, with four projection bumps. Ideal for projection welding onto the main beam to provide captive threads. After welding, thread must be re‑tapped (M8x1.25) to remove any weld spatter.
Both fasteners meet ISO 13918 standards for projection welding. Supplied in sealed bags to prevent contamination. Storage temperature -10°C to +40°C.
Step 1: Remove old upper frame from the truck. Clean all mating surfaces on chassis rails.
Step 2: If using the new main beam unassembled, first weld left and right connecting plates to the beam ends using MIG or MAG welding (fillet weld 4mm leg length). Ensure squareness (90° ±0.5°).
Step 3: Weld the four face projection bolts onto the front face of the beam at the marked positions (use resistance welder). Weld the six square nuts onto the rear face of the beam according to the jig holes.
Step 4: Attach grille brackets to the beam using M8 bolts (not included, but the welded nuts accept them). Attach license plate brackets using M6 bolts into the projection bolts.
Step 5: Install the completed upper frame assembly onto the truck chassis using original M12 bolts and washers (torque to 90 Nm).
Step 6: Reinstall grille, bumper covers, and lights. Test all attachments for secure fit. Adjust grille bracket height if needed.
Rust‑through of original beam – new beam with powder coating and zinc plating eliminates future corrosion. Stripped captive threads – new welding nuts provide fresh M8 threads. Broken grille mounting tabs – new grille brackets with rubber isolators prevent future breakage. Bent connecting plates – new plates restore alignment between frame and bumper supports.
Corrosion test: 720h salt spray (ASTM B117) on main beam and plates – red rust <5% on cut edges, coating intact. Welding bolt and nut testing: pull‑out force >10 kN for bolts, >8 kN for nuts. Vibration test: ISO 16750‑3, 10‑500Hz, 4.3 Grms, 48h – no loosening of welded fasteners, no cracking in welds.
Impact test: pendulum impact at 8 km/h – main beam deforms plastically but does not detach from connecting plates. Weld strength exceeds base metal strength.
Direct replacement for Shacman X5000 (2019‑2026) and X3000 (2015‑2026) upper bumper frames. Also fits X6000 with minor modification (connecting plate hole pattern may need reaming). Check original part number DZ9718962303 (main beam).
Complete solution: all structural and hardware components in one box. No need to source individual brackets or welding fasteners. Lower repair cost: 60% less than dealer assembly replacement. Reduced downtime: welding and installation can be done in 2‑3 hours by a skilled fabricator. Improved safety: new beam restores original crumple zone behavior.
Yes, a capacitor discharge or medium frequency resistance welder is required. Standard MIG welding will damage the projection rings. Contact your local welding shop if you lack equipment.
We recommend using the new left/right connecting plates included, as old plates may be distorted. The kit includes them.
Use M8 bolts tightened to 20 Nm into the welded square nuts. Do not exceed 25 Nm to avoid stripping.
No, they must be clean and dry for proper welding. Remove any oil with solvent before welding.
24 months on materials and weld integrity (if welded according to instructions). Excludes improper welding technique or collision damage.
