330103563 Stop End Cap Assembly XCMG XDE130 Dump Truck Parts

330103563 Stop End Cap Assembly for XCMG XDE130

The 330103563 Stop End Cap Assembly is a vital internal thrust-management component designed for the electric drive axle of the XCMG XDE130 Electric Driving Dump Truck. Translation Note: While listed in the factory parts manual as a “Stop End Cap,” this assembly is professionally recognized by transmission mechanics as the Planetary Thrust Bearing Cap.

Located deep within the Hub Reduction Gear Assembly (planetary final drive), this unit caps the planetary carrier and is tasked with absorbing the immense axial thrust loads generated by helical gears transferring torque to the massive 130-ton wheels. This comprehensive 6-part combination group provides everything needed for a complete thrust bearing replacement. It includes the heavy-duty steel end cap, the massive 29412E self-aligning thrust bearing, dynamic pre-load springs, and the necessary sealing O-ring to keep gear oil contained. We supply the complete 330103563 assembly for rapid drop-in repairs, as well as individual internal bearings and seals. Genuine XCMG OEM parts and premium aftermarket alternatives are available for global dispatch.

Below is the detailed 6-part breakdown of this end cap assembly according to the official XCMG XDE130 parts catalog. You can order the fully assembled bearing cap or request specific individual hardware components:

Features & Benefits of Our XCMG Final Drive Components

• Extreme Thrust Management: At the heart of this assembly is the heavy-duty 330103574 Thrust Self-Aligning Roller Bearing (29412E). This specialized bearing is engineered to accommodate shaft deflection while absorbing massive axial shock loads from the planetary gears.
• Active Bearing Pre-Load: Features 5 precisely calibrated tension Springs (Index 6) seated within the retainer. These springs apply constant, dynamic pre-load pressure against the thrust bearing, eliminating destructive end-play and preventing gear chatter during acceleration and deceleration.
• Impenetrable Fluid Sealing: The included 170×5 O-Ring (Index 2) ensures that the high-pressure, high-heat synthetic gear oil remains securely locked inside the hub reduction assembly, preventing bearing starvation and catastrophic failure.

Ordering & Logistics Guidelines

1. Multiply by Axle Requirement: A standard electric-drive rear axle utilizes two (2) of these thrust cap assemblies (one inside the left final drive and one inside the right). Please verify if you are rebuilding one or both sides and adjust your order quantity accordingly.
2. Select Individual Parts: You can order the fully assembled, factory-balanced end cap unit for a rapid transmission repair, or you can order specific internal components (such as just the 29412E roller bearing or the O-ring seal).
3. Provide Machine Serial Number: Bearing dimensions and spring tension rates can vary slightly depending on the specific electric traction motors and planetary sets paired with your truck. Providing your XCMG XDE130 VIN ensures 100% accurate component matching.
