• Model 639D

• Model 773

Application Scenarios & Case Analysis

The equipment models compatible with the 1U2671 cartridge, such as the 631C, 633D, 637, 639D (typically Scrapers), and 773 (an Off-Highway Truck), are primarily used in demanding environments requiring robust hydraulic power.

• Construction Sites: Scrapers (631C, 633D, 637, 639D) are extensively used for earthmoving, leveling, and material spreading on large construction projects. Reliable hydraulic pumps are vital for controlling the scraper bowl, ejector, and elevator, ensuring precise grading and efficient material handling. The 1U2671 cartridge provides the necessary flow and pressure for these critical functions, minimizing downtime on tight construction schedules.

• Mining Operations: In mining, off-highway trucks like the 773 are used to transport massive loads of ore or waste material. Their hydraulic systems power steering, braking, hoist cylinders, and other essential functions. A failing hydraulic pump cartridge can lead to significant operational disruptions. Replacing a worn 45 VQ series cartridge with the 1U2671 ensures the truck's hydraulic systems operate reliably under extreme loads and conditions, contributing to overall mine productivity and safety.

• Infrastructure Development: Projects like road building, dam construction, and large-scale land development rely heavily on the earthmoving capabilities of scrapers. The hydraulic system's performance directly impacts the speed and accuracy of earthmoving operations. A case often involves preventative maintenance where cartridges like the 1U2671 are replaced based on service hours or performance degradation, proactively preventing costly failures in the middle of critical project phases. The inclusion of the bushing in the cartridge kit simplifies this maintenance task.

Related Products

Other related VQ series cartridges and hydraulic pump components are also available, typically varying by flow rate, rotation, or series number to fit different pump models and applications. Examples include:

• Other 45 VQ Series Cartridges: Available in different GPM ratings (e.g., 50 GPM, 75 GPM) to match specific pump requirements.

• 35 VQ Series Cartridges: Used in pumps with lower flow requirements, often found in smaller or different types of machinery.

• Seal Kits: Essential for rebuilding or resealing hydraulic pumps and cartridges.

• Shafts and Bearings: Other internal components subject to wear in hydraulic pumps.

These related products are typically used in a wide range of mobile and industrial hydraulic systems across various industries, including construction, agriculture, manufacturing, and material handling.

Installation and Maintenance Considerations

Proper installation and regular maintenance are crucial for the longevity and performance of your hydraulic vane pump cartridge.

Common Issues & Solutions:

• Issue: Premature wear or failure.                
  Solution: Ensure the hydraulic fluid is clean and free of contaminants. Use the correct type and viscosity of hydraulic fluid as specified by the equipment manufacturer. Regularly change filters.

• Issue: Incorrect rotation (Left Hand vs. Right Hand).                
  Solution: Always verify the required rotation of the pump and cartridge before installation. Installing a cartridge with the wrong rotation will cause immediate failure. The 1U2671 is for Right Hand Rotation.

• Issue: Leakage after installation.                
  Solution: Ensure all seals and O-rings are properly seated and not damaged during installation. Verify that mounting bolts are tightened to the correct torque specifications. Check for damage to the pump housing mating surfaces.

• Issue: Noise or vibration.                
  Solution: This could indicate cavitation (lack of sufficient oil flow to the pump inlet) or air in the system. Check suction lines for restrictions or leaks. Ensure reservoir oil level is adequate. Bleed the system if necessary. It could also indicate internal wear, necessitating replacement.

• Issue: Reduced flow or pressure.                
  Solution: This is often a symptom of a worn cartridge. Internal leakage increases as vanes, rotor, and ring wear down. Replacing the cartridge with a new one like the 1U2671 is the typical solution. Verify system relief valve settings.

Always consult the equipment service manual for specific procedures and safety precautions when working on hydraulic systems.
