800363633 XCMG GR2605 motor grader drive axle

800363633 XCMG GR2605 motor grader drive axle

800363633 is the original drive axle assembly for the XCMG GR2605 grader. As a core transmission component of the chassis, it is responsible for transmitting power, supporting the vehicle body, and achieving speed reduction and torque amplification, ensuring the grader’s driving force for heavy-duty travel and operation.

Core Functions and Roles

Receives power from the gearbox and, through the main reducer and differential, reduces speed and amplifies torque to provide strong driving force to the wheels.

Bears the weight of the entire machine, ground impact forces, braking forces, and lateral steering forces, ensuring driving stability.

Achieves differential speed operation between the left and right wheels, allowing for smooth driving on uneven surfaces and reducing tire wear.

Integrates brakes, half-shafts, and axle housings, providing stable and reliable transmission support for the walking system.

Replacement and Maintenance Points

During installation, tighten the connecting parts to the original torque, calibrate the positioning, and ensure the coaxiality of the transmission.

Add the specified special gear oil, change the oil regularly, and keep the oil clean.

Avoid prolonged overloading, sudden starts, and sudden braking to reduce impact damage to the gears and bearings inside the axle.

If oil leakage, abnormal noise, overheating, or slippage occurs, stop the machine immediately for inspection and repair to prevent further damage.
