The genuine XCMG 380907140 Scraper Body is a heavy‑duty, welded steel mainframe component that forms the core of the moldboard assembly on XCMG GR series motor graders. This OEM 380907140 scraper body provides the structural backbone for mounting cutting edges, side plates, wear strips, and hydraulic tilt cylinders. Manufactured from high‑strength, abrasion‑resistant steel (Hardox 450 equivalent) with precision‑aligned bolt holes and reinforced cross‑ribs, the XCMG scraper body withstands tremendous impact, bending, and torsional forces encountered during road grading, ditching, and leveling operations. The 380907140 scraper body is a direct replacement for worn or cracked moldboard frames on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders.
This scraper body supports the entire blade assembly, including the cutting edge, end bits, and wear plates. A bent, cracked, or excessively worn scraper body causes poor blade profile, uneven material spreading, and accelerated wear of bolted wear parts. Replacing a damaged scraper body with genuine XCMG 380907140 restores original blade geometry, improves grading accuracy, and extends the service life of cutting edges and wear components.
The scraper body also serves as the mounting interface for circle drive brackets and blade lift arms. XCMG 380907140 ensures perfect alignment of all moldboard attachments, reducing operator fatigue and delivering consistent finish grades.

The 380907140 scraper body is the primary structural element that holds the cutting edge and transfers push forces from the grader frame to the material being graded. It must resist bending, twisting, and impact from rocks and frozen ground.
A straight, rigid scraper body ensures that the cutting edge contacts the ground evenly across the full width. A bent body creates high and low spots, causing washboarding and poor finish grade.
The scraper body also provides mounting for side plates, end bits, and the moldboard tilt mechanism. Replacing a damaged 380907140 restores blade flatness and improves material rolling efficiency.
Each 380907140 scraper body is laser‑cut from Hardox 450 or equivalent AR steel, then formed on a press brake to achieve the precise curved profile. All edges are chamfered to prevent stress risers.
Fully automated robotic welding with double‑fillet joints ensures consistent penetration and minimal distortion. After welding, the entire assembly is stress‑relieved in an oven to remove internal stresses.
The cutting edge mounting face is milled flat to within 1 mm across the full length. XCMG uses a coordinate measuring arm to verify all hole positions and bolt pattern alignment.
Replacing a scraper body is a major repair requiring lifting equipment. Remove the cutting edge, side plates, and wear strips from the old scraper. Unbolt the circle drive brackets and lift arms.
Lift the old scraper body off the circle using an overhead crane. Clean the mating surfaces on the circle and drawbar. Position the new 380907140 scraper body and secure with new high‑strength bolts torqued to 500 Nm.
Install a new cutting edge, wear strips, and side plates. Check blade flatness with a straightedge – any gap over 2 mm requires shimming or replacement of worn circle wear parts.
Visible cracks along the top edge or near bolt holes, permanent bending causing the blade to bow (concave or convex), weld fractures at rib connections, and uneven wear of cutting edges.
If the scraper body has been straightened in the past or shows severe pitting from corrosion, replace it with genuine XCMG 380907140 to ensure structural integrity and safe operation.
Inspect the scraper body for cracks every 1,000 operating hours, especially after hitting buried rocks. Use dye penetrant on suspect areas around the mounting bolts and welds.
Check the flatness of the cutting edge mounting face with a 2 m straightedge – a gap over 2 mm indicates the scraper body may be bent. Replace the 380907140 if found bent.
Keep the scraper body clean and touched up with paint to prevent corrosion. If stored outdoors, cover the blade to prevent water pooling on the top ribs.
Genuine XCMG 380907140 scraper bodies are manufactured in ISO 9001 certified facilities and come with a 12‑month warranty against structural failure. Regional stocking hubs: Houston, Rotterdam, Dubai, Shanghai.
Ocean freight is standard for large components (2‑4 weeks). Air freight available for urgent orders (3‑7 days). Bulk orders receive volume discounts and dedicated shipping.
Aftermarket scraper bodies often use lower grade steel (AR400) that wears faster and has poor weld quality. Genuine XCMG 380907140 uses certified Hardox 450 with full penetration welds. Order genuine today to restore your grader’s grading accuracy and blade rigidity.
A bent or cracked scraper body cannot be economically repaired – replacement is the only safe option. Keep the 380907140 scraper body in mind during major undercarriage rebuilds. Proactive replacement ensures consistent grade quality and reduces operator fatigue.
Upgrade your motor grader’s moldboard performance with XCMG genuine scraper bodies. Laser‑cut, robotic‑welded, and stress‑relieved – order the 380907140 Scraper Body now and achieve perfect blade flatness for thousands of tons of material moved.
