The genuine OEM 380906313 Adjustment Shim (Gr215x.13-5) is a precision-engineered component designed specifically for XCMG motor graders. This essential shim is used to accurately set preload, backlash, and endplay in critical assemblies such as the circle drive gearbox, final drive, pivot joints, and bearing housings in GR series graders, delivering uncompromised reliability and precision in the most demanding construction environments.
Manufactured to original XCMG specifications, the 380906313 adjustment shim is stamped from high-quality spring steel with a corrosion-resistant phosphate coating. It is available in precise thickness increments (typically 0.1 mm, 0.2 mm, 0.5 mm, or 1.0 mm) to allow technicians to achieve exact mechanical tolerances. It operates reliably from -40°C to +150°C and is designed to maintain its thickness under high compressive loads without crushing or deforming.
Using genuine XCMG 380906313 adjustment shims eliminates gear noise, excessive bearing wear, and premature component failure. Each shim undergoes 100% thickness verification and edge deburring before packaging. Restore your grader’s mechanical precision and component longevity with authentic OEM quality that matches the original equipment fitted at the XCMG factory.
The 380906313 adjustment shim is a critical component for setting correct mechanical tolerances in XCMG motor graders. Unlike rubber or plastic shims, this steel shim provides non-compressible, stable thickness under high clamping forces. It is used to adjust bearing preload, gear backlash, and axial endplay in assemblies such as the circle drive gearbox, final drive, and articulation pivot bearings.
The shim is precision-stamped from high-carbon spring steel, then heat-treated to achieve a spring temper (40-50 HRC). This hardness ensures the shim retains its thickness and flatness even after years of service under high loads and vibration. The edges are deburred to prevent damage to mating components, and the surface is phosphate-coated or oil-impregnated to resist corrosion.
Each 380906313 shim is manufactured to exacting tolerances (±0.01 mm) and verified using laser micrometers. This precision allows technicians to select and stack shims to achieve the exact clearance specified in the XCMG service manual, ensuring optimal gear contact pattern, bearing life, and smooth operation.
This adjustment shim directly replaces OEM part 380906313 (Gr215x.13-5) on XCMG GR135, GR165, GR180, GR200, GR215, GR300, GR350, GR2405, as well as older PY165G, PY170G, PY180G, and PY200G motor graders. The XCMG GR Series Motor Graders are essential construction machines for national defense engineering, mine construction, town and country roads building, and farmland improvement.
The 380906313 adjustment shim is typically used to set bearing preload in the circle drive gearbox (adjusting the taper roller bearings on the circle drive pinion), to set backlash between the worm gear and worm wheel, and to adjust endplay in articulation pivot bearings. It is also used in the final drive to set differential bearing preload and pinion depth.
Standardizing on genuine XCMG 380906313 adjustment shims ensures accurate tolerances and consistent assembly results across your fleet. Using genuine components eliminates guesswork, reduces rework, and extends gearbox and bearing life. The GR series graders are widely used for ground leveling, ditching, slope scraping, bulldozing, scarification, and snow removal on highways, airports, farmlands, and mining areas.
Before installing the 380906313 adjustment shim, clean all mating surfaces and inspect for burrs or damage. Measure the housing depth and component stack-up using a depth micrometer. Calculate the required shim thickness using the formula: Shim Thickness = (Housing Depth) – (Component Stack Height) – (Desired Endplay or Preload). Select one or more shims to achieve the calculated thickness within ±0.02 mm.
If using multiple shims, stack them with the thicker shims at the bottom to maintain flatness. Apply a thin film of clean oil to each shim to prevent rust during assembly. Torque the retaining bolts to the specified value, then rotate the assembly to check for smooth operation. For bearing preload, measure the starting torque with a torque wrench and compare to the XCMG service manual value. Adjust shim thickness as needed.
During scheduled overhauls (every 4000 hours), replace any shims that show corrosion, deformation, or edge wear. Never reuse a shim that has been compressed or bent. Always use genuine XCMG 380906313 shims to ensure correct material hardness and thickness accuracy.
All 380906313 adjustment shims are manufactured in XCMG’s ISO 9001:2015 and IATF 16949 certified facilities. Each shim undergoes 100% thickness verification using automated laser measurement, hardness testing (40-50 HRC), and visual inspection for burrs or edge cracks. Random samples are subjected to compression testing (1000 MPa) to confirm no deformation.
Full traceability from raw material coil to finished shim allows quality audits. Salt spray testing (240+ hours) validates corrosion resistance. XCMG provides a comprehensive 12-month or 2000-hour warranty against manufacturing defects.
Counterfeit shims often use mild steel that compresses under load, leading to loss of preload, gear noise, and premature bearing failure. Genuine 380906313 shims use hardened spring steel that maintains thickness and flatness for the life of the assembly. Aftermarket shims may have inaccurate thickness tolerances, causing incorrect gear mesh and overheating.
Fleet operators report that genuine XCMG shims eliminate gearbox rework and extend bearing life by up to 2x compared to aftermarket alternatives. Protect your grader’s drivetrain precision and reliability with authentic XCMG quality. Always verify the OEM marking and material certification to avoid costly failures.
The 380906313 adjustment shim is stocked in XCMG regional warehouses across North America, Europe, Asia-Pacific, the Middle East, and Africa. Standard lead time is 3-5 working days. Express freight options are available for critical breakdown situations. Bulk orders receive competitive wholesale pricing and full technical support.
Each shim is packed in anti-rust oil and sturdy cartons with foam inserts, suitable for sea or air freight. Technical datasheets and installation guides are provided. Dealers benefit from XCMG’s extensive parts distribution system and dedicated after-sales assistance.
A large infrastructure contractor in Australia replaced all aftermarket shims on 18 XCMG GR215 graders with genuine 380906313 shims during a gearbox overhaul. After 5,000 operating hours, zero gearbox failures were recorded, and bearing preload remained within factory specifications. The contractor reported a 60% reduction in gearbox noise and a 40% reduction in vibration.
In Canadian mining operations at -40°C, the 380906313 adjustment shim maintained dimensional stability without cracking or compressing, while aftermarket shims became brittle and fractured. Operators reported consistent gearbox performance and reduced downtime even under extreme cold conditions.
The 380906313 adjustment shim is available as a single unit or in kits containing multiple thicknesses (0.1, 0.2, 0.5, 1.0 mm). Custom shim thicknesses (down to 0.05 mm) can be ordered with a 10-day lead time. Minimum order quantity for custom is 20 pieces.
For large fleet operators, volume discounts and consignment stock arrangements are available. XCMG’s dedicated parts team provides technical assistance for complex tolerance calculations. Always specify OEM number 380906313 (Gr215x.13-5) to ensure you receive genuine XCMG quality.
If you notice gear whine or howling from the circle drive gearbox, incorrect bearing preload may be the cause. Check the starting torque; if too low, add a 0.1 mm 380906313 shim. If too high, remove a 0.1 mm shim. Always re-measure after each adjustment.
If you feel excessive endplay in a pivot joint, the existing shims may have worn or compressed. Disassemble, measure the clearance, and replace the shim stack with new genuine 380906313 shims to restore the correct endplay (typically 0.05–0.15 mm for articulation pins).
If a shim shows rust or corrosion, replace it immediately. Rust can flake off and contaminate bearings or gears. Always store spare shims in a dry, oiled environment.
