The 800106933 Gear is a genuine OEM power transmission component manufactured by XCMG for motor grader drivetrains. This high‑precision gear is designed for use in the gearbox, final drive, and wheel hub assemblies of XCMG GR series motor graders. Engineered from premium alloy steel and case‑hardened for maximum durability, the 800106933 gear ensures smooth torque transfer, high load capacity, and extended service life under extreme grading conditions.
The 800106933 gear features precision‑cut involute teeth with advanced grinding to achieve ISO 6 or better accuracy, reducing noise and vibration while improving efficiency. It directly replaces worn, chipped, or broken gears in the transmission or final drive system of XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders. A compromised gear can lead to power loss, irregular motion, and catastrophic drivetrain failure.
Every 800106933 gear is manufactured under strict quality control, with 100% magnetic particle inspection for cracks and hardness testing across the tooth flank and root. The gear is shot‑peened to improve fatigue resistance, then phosphate‑coated for corrosion protection. Proper gear meshing and lubrication are essential for motor grader performance, and replacing a damaged gear with the genuine XCMG 800106933 restores original equipment reliability.

The XCMG 800106933 gear is a fundamental component in the motor grader’s power transmission chain. It transfers rotational force from the gearbox to the final drive and eventually to the wheels, enabling precise blade control and traction.
This gear is typically installed in the output shaft assembly of the transmission or within the tandem drive housing. Its tooth geometry and metallurgy are specifically optimized for high‑shock, low‑speed, high‑torque applications encountered during heavy grading and ripping operations.
A worn or broken 800106933 gear will cause slipping, noise (whining or clunking), erratic wheel motion, and eventual loss of propulsion. Replacing it with the genuine XCMG part restores driveline integrity and prevents secondary damage to bearings, shafts, and mating gears.
Each 800106933 gear starts as a forged blank from 20CrMnTi alloy steel, known for its excellent hardenability and impact strength. The forging process aligns the grain flow, resulting in superior fatigue resistance compared to cast or cut‑from‑bar gears.
After rough machining, the gear undergoes carburizing in a controlled atmosphere furnace, adding a high‑carbon case while retaining a tough core. It is then quenched and tempered to achieve the specified surface hardness of 58–62 HRC and core hardness of 33–38 HRC.
The tooth flanks are precision ground using CNC gear grinders, achieving profile modifications (tip relief and root fillet optimization) that reduce stress concentrations and noise. 100% of production is inspected via coordinate measuring machine (CMM) and magnetic particle testing.
Replacing the 800106933 gear requires partial disassembly of the transmission or final drive. Always consult the XCMG service manual for your specific grader model. Drain the lubricant and clean the housing to prevent contamination.
Inspect the mating gear, bearings, and shaft for wear. Replace any worn components simultaneously. Heat the new gear to 80–100°C (176–212°F) for easier installation on the shaft, but never use an open flame. Apply clean gear oil to the bore and shaft.
Torque the retaining nut or bolt to factory specifications (typically 250–300 N·m). Verify backlash and tooth contact pattern using marking compound. Fill with approved lubricant and run the grader at low speed, checking for unusual noise or vibration.
Common indicators that the 800106933 gear requires replacement: metallic particles in the oil, audible whining or clunking that changes with speed, vibration in the driveline, loss of power to wheels, or erratic blade movement due to speed variations. Visual inspection may reveal chipped, pitted, or broken teeth.
If a gear tooth has fractured, stop operation immediately to avoid locking the drivetrain. Delaying replacement can scatter debris throughout the transmission, destroying bearings and the housing. The cost of a genuine 800106933 gear is minimal compared to a full transmission overhaul.
Aftermarket gears often use inferior materials (e.g., 45# steel without case hardening) that wear rapidly, causing premature tooth pitting and breakage. They may skip the critical shot‑peening or grinding steps, resulting in rough surfaces and high noise levels. The genuine 800106933 gear is built to XCMG’s blueprint, ensuring correct tooth profile, hardness, and fit.
A counterfeit gear may have mismatched module or pressure angle, leading to incorrect backlash and excessive stress on mating components. Genuine XCMG gears are batch‑tested for dimensional accuracy, hardness profile, and metallurgical consistency. Each gear is laser‑etched with the XCMG logo and part number for traceability.
