800361418 XCMG GR2605 motor grader wheel-side assembly

800361418 XCMG GR2605 motor grader wheel-side assembly

The 800361418 wheel-side assembly is a core power transmission and load-bearing component of the construction machinery’s walking system. Integrating components such as the wheel rim, hub, bearings, and seals, it transmits drive power, supports equipment weight, and is suitable for heavy-duty and complex road conditions. It features wear resistance, impact resistance, excellent sealing, and stable operation, ensuring smooth equipment movement.

Core Technical Parameters

1. Model: 800361418, a dedicated wheel-side assembly for construction machinery, precisely matched to the host machine’s walking system mounting interface.

2. Compatible Media: No specific media required; its core function is power transmission, load support, and sealing protection for the walking system.

3. Material: Wheel rim (Q355B high-strength carbon steel), hub (40Cr alloy steel), heat-treated for high strength, bending resistance, and deformation resistance.

4. Operating Temperature: -40℃~120℃, suitable for harsh outdoor working environments such as high and low temperatures, dust, mud, and bumpy conditions.

5. Surface Treatment: Rim powder coating + anti-rust primer, hub quenching + blackening passivation treatment, providing rust prevention, corrosion resistance, and wear resistance.

6. Specifications and Dimensions: Rim is compatible with the main unit’s standard tire model; hub bore diameter and bolt hole positions are precise, perfectly matching the main unit’s mounting position without additional adjustments.

7. Load Capacity: Suitable for heavy-duty operating conditions, stably supporting the entire weight of the equipment and withstanding radial and axial impact loads during movement.

8. Fit Precision: All components are tightly assembled; bearings have reasonable clearances with the hub and rim, ensuring smooth operation without jamming or abnormal noise, and excellent sealing performance.

Core Functions and Roles

As a core component of the walking system, it receives power from the drive system, rotating the tires to achieve stable movement and operation. It stably supports the weight of the entire machine, distributing ground reaction forces and preventing excessive stress on one side from damaging the tires or walking components. Its integrated sealing structure prevents dust, mud, and other impurities from entering, protecting core components such as bearings. It reduces rotational friction, lowers energy consumption, and improves walking efficiency. It possesses strong impact resistance and wear resistance, adapting to complex road conditions and extending the overall service life of the walking system.

Suitable Scenarios

Widely used in various construction machinery such as excavators, loaders, bulldozers, and road rollers, it is suitable for heavy-duty and complex road conditions in infrastructure construction, mining, earthwork engineering, and road construction. It is an indispensable core assembly component of the equipment’s walking system, directly determining the equipment’s walking stability, operating efficiency, and safety.

Common Faults and Troubleshooting

For abnormal noises from the wheel rim, check for bearing wear, insufficient lubrication, or loose component connections. Add special grease and tighten connections. If the bearing is severely worn, replace it immediately. For wheel rim deformation or cracking, this is often caused by heavy-load impacts or collisions. Replace the wheel rim assembly immediately to prevent tire damage or loss of control. For wheel hub rust or oil leaks, check for aging seals and damaged surface protective layers. Replace the seals and apply rust prevention treatment. For wheel slippage or pulling to one side, check component clearances, tire pressure, and installation accuracy. Correct any deviations and replace worn parts.
