The 380907119 Blade Extension Lever Assembly is a genuine OEM control component manufactured by XCMG for motor graders. This heavy‑duty lever assembly operates the blade side‑shift (extension) hydraulic circuit, allowing the operator to move the moldboard left or right for edge cutting, ditching, and shoulder work.
Engineered to withstand high cycle fatigue, dust, and extreme temperatures, the 380907119 lever assembly features forged steel construction, sealed pivot bushings, and a comfortable ergonomic grip. It directly replaces worn, loose, or broken blade extension levers on XCMG GR series graders.
Each unit includes the lever arm, pivot shaft, bronze bushings, mounting bracket, and all necessary hardware. The detent mechanism provides positive feedback at neutral and full stroke positions, ensuring precise blade offset control during grading operations.

The XCMG 380907119 Blade Extension Lever Assembly gives the operator direct mechanical control over the blade side‑shift hydraulic circuit. By moving the lever left or right, the operator commands the valve spool, extending or retracting the moldboard laterally. This independent control is essential for cutting close to obstacles, shaping shoulders, and performing offset grading.
The lever features a robust detent mechanism that holds the valve in the neutral position, preventing unintended blade drift. When pushed past the detent, the lever engages the extend or retract function. The spring‑loaded return brings the lever back to neutral when released, but an optional friction lock can maintain continuous offset for long passes.
The 380907119 assembly is a direct replacement for the original blade extension lever on XCMG GR series motor graders. Worn bushings, bent lever arms, or broken detent springs cause sloppy control and inaccurate blade positioning. Replacing the entire assembly restores crisp, predictable side‑shift response and reduces operator fatigue.
The lever arm is forged from high‑carbon steel, then heat‑treated to resist bending or cracking under repeated heavy use. The pivot area uses replaceable oil‑impregnated bronze bushings that never require greasing, reducing maintenance. The mounting bracket is fabricated from 6 mm steel plate, powder‑coated in XCMG blue (#004C96) for corrosion resistance.
The handle grip is molded from TPE (thermoplastic elastomer), which remains comfortable in both freezing and hot conditions. The textured surface provides positive traction even with oily gloves. The grip also incorporates a small lip to prevent the operator’s hand from slipping during aggressive lever movements.
All fasteners are Grade 8.8 or higher, with zinc‑plated finish. The clevis pin that connects the lever to the hydraulic valve spool is hardened steel and includes a cotter pin for security. The 380907119 is designed for 1 million actuation cycles under full load.
Replacing the blade extension lever assembly is straightforward. Park the grader on level ground, lower the blade to the ground, and shut off the engine. Remove the operator’s floor plate to access the lever linkage. Disconnect the clevis pin from the valve spool, then unbolt the mounting bracket (usually 4 M10 bolts).
Install the new 380907119 assembly in reverse order. Adjust the linkage so that the lever is vertical (neutral position) when the valve spool is centered. Use the threaded rod end to fine‑tune the length. Torque the mounting bolts to 45 Nm. Apply a small amount of anti‑seize to the clevis pin before insertion.
After installation, start the engine and test blade extension function. The lever should move smoothly through its range, with a distinct detent feel at neutral. If the blade drifts when the lever is in neutral, adjust the linkage length. No special tools are required beyond standard metric wrenches.
Aftermarket lever assemblies often use mild steel arms that bend under load, or plastic bushings that wear out within months. The genuine XCMG lever is forged from heat‑treated steel, ensuring it remains straight and true even after years of heavy use. The bronze bushings are self‑lubricating and last 5x longer than nylon alternatives.
Counterfeit levers may have incorrect geometry, causing the valve spool to bottom out or not fully stroke. This results in slow side‑shift response or incomplete travel. The 380907119 is dimensionally identical to the original, guaranteeing proper valve actuation and full cylinder travel.
XCMG provides a 12‑month warranty against manufacturing defects. Each lever assembly is stamped with the XCMG logo and part number. This supersedes older numbers 380907001 and 380907088, with improved bushing material and a stronger pivot shaft.
Common symptoms of a failing blade extension lever: excessive side‑to‑side play at the pivot, a “mushy” detent feel, the lever not returning to neutral by itself, or the blade drifting while grading. Inspect the bushings for ovality and the lever arm for bending. Also check the clevis pin for wear grooves.
Preventive replacement every 5,000 operating hours is recommended for graders used in heavy road construction or mining. A worn lever reduces operator control, leading to uneven blade offset and increased fuel consumption. Replacing the assembly restores crisp, predictable side‑shift response.
Keep the pivot area clean of mud and debris. While the bushings are self‑lubricating, occasional application of light oil can extend their life. Never use a pipe extension on the lever – the design force is sufficient; forcing it can bend the arm or damage the valve.
