330103566 Class-1 Reducer Assembly XCMG XDE130 Dump Truck Parts

330103566 Class-1 Reducer Assembly for XCMG XDE130

The 330103566 Class-1 Reducer Assembly is a vital torque-multiplying powerhouse located within the electric drive axle of the XCMG XDE130 Electric Driving Dump Truck. Translation Note: While listed in the factory parts manual as a “Class-1 Reducer,” this assembly is professionally recognized worldwide as the Primary Planetary Carrier or First-Stage Planetary Gear Assembly.

In ultra-class electric drive trucks, the traction motors spin at extremely high RPMs. This first-stage planetary carrier receives that high-speed rotational energy directly from the primary sun gear and initiates the first major step of gear reduction, passing massive torque onto the secondary stage. Because it is subjected to intense shearing forces and rotational friction, this complete 7-part kit features a heavy-duty forged steel carrier, three precision-cut planet gears, heavy-duty cylindrical roller bearings, and premium retaining hardware. We supply the complete 330103566 master assembly for rapid drop-in repairs, as well as individual internal gears and bearings for specialized transmission rebuild shops. Genuine XCMG OEM parts and premium aftermarket alternatives are available for global dispatch.

Features & Benefits of Our XCMG Final Drive Carriers

• First-Stage Torque Multiplication: The 3 precision-forged Primary Planet Gears (330103580) seamlessly step down the immense high-RPM input from the electric traction motors, ensuring a massive, shock-free power transfer to the secondary planetary stage.
• Severe-Duty Load Bearings: Includes six premium NJ2215 Cylindrical Roller Bearings perfectly spaced with dedicated distance sleeves to manage intense radial loads, preventing planetary gear deflection and catastrophic metal-on-metal failure.
• Vibration-Proof Assembly: The heavy-duty planet shafts are securely locked into the main carrier housing utilizing structural pressure plates and GB-standard M12 bolts, ensuring the assembly remains rigidly intact under severe reversing loads.

Ordering & Logistics Guidelines

1. Multiply by Axle Requirement: A standard electric-drive rear axle utilizes two (2) of these primary planetary carriers (one for the left final drive and one for the right). Please verify if you are rebuilding one or both sides and adjust your order quantity accordingly.
2. Complete Unit vs. Internal Rebuild: You can order the fully assembled, factory-balanced carrier unit for a rapid drop-in rear axle repair, or you can order specific internal components (such as planetary gears or NJ2215 bearings) if you run a specialized transmission rebuild facility.
3. Provide Machine Serial Number: Planetary gear tooth counts, reduction ratios, and splines can vary depending on the specific electric traction motors paired with your truck. Providing your XCMG XDE130 VIN ensures 100% accurate component matching.
