Applicable Equipment

This hydraulic vane pump cartridge is designed to be compatible with and install directly into the hydraulic pumps of the following Caterpillar CAT Wheel-type Loader models:

• Caterpillar CAT Wheel-type Loader G926

• Caterpillar CAT Wheel-type Loader 926

• Caterpillar CAT Wheel-type Loader 926E

Application Scenarios & Case Studies

Caterpillar 926 series loaders (G926, 926, 926E) are widely utilized across various heavy-duty applications where reliable hydraulic power is non-negotiable. A functioning hydraulic pump is at the heart of their productivity.

• Construction & Quarrying: Used for loading trucks with aggregates (sand, gravel, stone), backfilling, and material relocation. A strong hydraulic system ensures fast lift and dump cycles, directly impacting project timelines and efficiency.

• Agriculture: Essential for handling feed, moving large bales, clearing land, and general farm maintenance. Precise and reliable hydraulics prevent damage to materials and ensure safe operation around livestock or structures.

• Industrial & Waste Management: Employed in material handling within plants, loading waste into compactors or trucks. Consistent hydraulic pressure is needed for lifting heavy or uneven loads safely.

• Case Example: A company operating a CAT 926E loader for loading grain found their lift speed significantly reduced, impacting their loading capacity per hour. Investigation revealed wear in the hydraulic pump cartridge. Replacement with the 1U2668 cartridge restored the hydraulic flow to specifications, immediately resolving the slow lift issue and enabling the loader to meet its operational targets again.

Installation & Maintenance: Common Issues and Solutions

Proper installation and diligent maintenance are paramount to ensuring the longevity and optimal performance of your new hydraulic pump cartridge. Be aware of these common issues:

• Issue: Reduced Hydraulic Power (Slow/Weak Function).                
  Cause: Worn pump cartridge, air in the system, clogged filter, faulty relief valve, low fluid.                
  Solution: Replace cartridge, bleed air, replace filter, inspect relief valve, check/fill fluid.

• Issue: Excessive Pump Noise (Whining, Grinding).                
  Cause: Air in the system (cavitation), contamination, misalignment, worn bearings.                
  Solution: Bleed air, ensure clean fluid/system, check pump-to-motor alignment, inspect internal components for wear.

• Issue: Hydraulic System Overheating.                
  Cause: Low fluid level, incorrect fluid type, restricted flow, internal leakage in components (cylinders, valves), system overload.                
  Solution: Check/correct fluid level & type, inspect hoses/fittings for restrictions, check cylinders/valves for bypass leaks, ensure equipment is used within load limits.

Installation Best Practices: Always work in a clean environment. Flush the system if contamination is suspected. Use the specified hydraulic fluid. Carefully align the cartridge during installation. Ensure all connections are secure and torqued correctly. Bleed all air from the system after reassembly before operating at full load.

Maintenance Tips: Adhere strictly to the equipment's maintenance schedule for hydraulic fluid and filter replacement. Regularly inspect hoses, fittings, and cylinders for leaks. Monitor hydraulic system pressure and performance for any signs of degradation.
