Functions and Applications:

• Core power supply: Provides high-pressure oil flow for boom lifting, bucket digging, swinging, and steering of backhoes, and bucket loading and unloading of loaders, forming the power foundation for multi-action coordination.
• Load sensing control: Closed-center design enables on-demand oil supply, reducing energy loss, lowering equipment fuel consumption, and improving operational precision.
• Heavy-duty adaptability: Capable of continuous high-intensity excavation and loading operations, adaptable to various construction scenarios such as mines, infrastructure, and farms.

Core product advantages:

• Original factory matching:** Dimensions, interfaces, and performance are fully compatible with John Deere original equipment manufacturer (ODM). Installation requires no modification; directly replaces the original AT334876 pump.
• High efficiency and stability: Axial plunger structure with a volumetric efficiency >95%, low noise operation, low internal leakage, and strong long-term operational stability.
• Durable and robust: Reinforced sealing components and high-precision bearings withstand complex working conditions such as construction dust, bumps, and extreme temperatures.
• Easy maintenance: Universal A10V series plunger pump structure; parts are readily available, maintenance costs are lower than original parts, offering excellent value.

Replacement points: Directly replaces the original John Deere AT334876 pump; no modification to piping or supports required. If using a Rexroth R986110413 equivalent, ensure interface and displacement compatibility to avoid compatibility errors.
