-
Supplies pressurized oil to hydraulic cylinders for boom, arm, and bucket movements.
5.2 Swing Mechanism
-
Powers the excavator’s rotation by driving the swing motor.
5.3 Travel Motors
-
Provides hydraulic pressure for track or wheel movement.
5.4 Auxiliary Hydraulic Functions
-
Operates attachments like breakers, grapples, and augers.

Common Failures & Troubleshooting
Despite their robustness, gear pumps may experience failures due to wear, contamination, or improper maintenance. Common issues include:
6.1 Low Pressure or Flow
-
Causes: Worn gears, internal leakage, clogged filters, or air ingress.
-
Solutions: Inspect and replace damaged gears, check for leaks, clean/replace filters, and bleed air from the system.
6.2 Overheating
-
Causes: Excessive load, low fluid levels, or degraded oil.
-
Solutions: Ensure proper oil viscosity, maintain correct fluid levels, and avoid overloading.
6.3 Excessive Noise & Vibration
-
Causes: Cavitation, misalignment, or bearing wear.
-
Solutions: Check suction lines for restrictions, realign pump shafts, and replace worn bearings.
6.4 Fluid Leakage
-
Causes: Damaged shaft seals or worn housing.
-
Solutions: Replace seals and inspect the pump casing for cracks.
