description

139-6084 gear pump serves as main hydraulic power unit for CAT950G wheel loader, driven by engine. It converts mechanical power into pressurized hydraulic fluid for boom, bucket and steering hydraulic systems. Precision meshed alloy gear pair provides constant flow output. During heavy bucket loading and lifting, the pump maintains steady oil supply to keep working speed consistent; under light load or idle travel, it reduces unnecessary power waste and heat accumulation.
Internal gear pair, bearing groups and seal assembly adopt high-strength material with precision machining. Cast iron pump housing adopts stress relief annealing to eliminate casting residual stress, resisting vibration and solid particle contamination on quarry and aggregate sites.High-performance FKM fluorine rubber sealing assembly delivers reliable high temperature resistance and anti-aging property, reducing internal volumetric leakage and external oil seepage.

advantage

- High precision alloy gear pair maintains stable flow under frequent loading cycles
Tightly matched gear set minimizes flow fluctuation during repetitive bucket filling and lifting, keeping consistent cycle time for bulk material loading.
- Integrated cast iron pump body resists shock from heavy rock and gravel loading
Robust one-piece housing can withstand cyclic impact when loading hard stone and aggregate, reducing housing deformation under frequent heavy load.
- Stable constant flow design ensures smooth boom and bucket compound action
Fixed flow characteristic enables boom lifting and bucket curling to operate simultaneously with steady movement, improving loading cycle efficiency.
- Low internal leakage design controls temperature rise for long shift continuous operation
Precision fit between gears and housing reduces internal leakage, preventing excessive heat buildup during all-day continuous loading in quarries.
- Easy bolt-on replacement, matches original mounting and port layout
Direct replacement design follows OEM mounting dimensions and oil port arrangement, shortening machine downtime during on-site repair.

FAQ 

Q1: Which machine does 139-6084 gear pump fit?
A1: This hydraulic gear pump fits CAT950G wheel loader and compatible with 960G. Confirm machine serial number before purchase.

Q2: What hydraulic functions does this pump support?
A2: It provides hydraulic oil for boom lifting, bucket tilt and steering system, completing bulk material loading, stockpile handling and material transfer work.

Q3: What are typical failure symptoms of worn pump?
A3: Typical symptoms: slower boom lifting speed, unstable bucket movement during heavy loading, noticeable noise under high load, obvious temperature rise after long working hours, shaft seal oil leakage.

Q4: What inspections should be done before installing new pump?
A4: Inspect boom cylinders, bucket cylinder, main control valve and filter elements. Fully flush hydraulic tank and pipelines to remove metal debris. Replace degraded hydraulic oil before assembly.

Q5: What hydraulic oil should be used for this pump?
A5: Use ISO VG46 anti-wear hydraulic oil. Working temperature -20℃~105℃. Do not mix different oil brands, avoid long continuous running under peak pressure.
