Hydraulic Gear Pump 231-6587 10R-7978 for 950G 962G Wheel Loader

This hydraulic gear pump, identified by part numbers 231-6587 and 10R-7978, is the dedicated hydraulic power unit engineered for the hydraulic systems of 950G and 962G wheel loaders. It delivers high-pressure hydraulic oil to drive the lift, tilt, and steering assemblies.

Built around a precision gear structure, the pump provides stable flow output and is manufactured from wear-resistant alloy material using precision machining processes. It is designed for direct replacement installation and delivers consistent output performance under heavy-duty loading and earthmoving conditions.

• Internal gear and bushing wear, leading to pressure drop and weak action
• Internal seal failure resulting in hydraulic oil leakage
• Abnormal noise and vibration during operation
• Gear sticking and flow instability
• Housing cracks caused by overload and high pressure

• Confirm the part number and machine serial number before ordering
• Verify spline specification, mounting dimensions, and control type
• Request strict pressure and performance testing before shipment
• Shockproof wooden packaging to prevent transit damage
• Quality warranty covering manufacturing defects
