Hydraulic Pumps: Gear Pump, Main Pump, Oil Pump, Hydraulic Motor

The hydraulic pump is the heart of the excavator’s hydraulic system, providing the pressure and flow needed to power digging, lifting, and attachment operations.

Gear Pump

Gear pumps deliver a steady flow of hydraulic oil to support basic operations, making them a cost-effective and durable choice for medium-duty applications.

Main Pump

The main hydraulic pump is the core of the excavator’s hydraulic system, supplying high pressure and flow to operate the boom, arm, and bucket.

Oil Pump

Oil pumps maintain proper lubrication and circulation of hydraulic oil, reducing wear and protecting system components.

Hydraulic Motor

Hydraulic motors convert hydraulic pressure into rotary motion, powering functions such as swing, travel, and attachments.

Check Valve

Check valves allow hydraulic fluid to flow in only one direction, preventing backflow and protecting the system from pressure loss.

Pilot Valve

Pilot valves control low-pressure pilot oil that directs the main hydraulic system, enabling precise control of boom, arm, and bucket functions.

Throttle Valve

Throttle valves regulate the flow rate of hydraulic oil, helping to adjust speed and balance across different functions.

Solenoid Valve

Solenoid valves use electrical signals to control hydraulic oil flow automatically.

Hydraulic Cylinders: Bucket Cylinder, Boom Cylinder, Arm Cylinder & Travel Cylinder

Bucket Cylinder

The bucket cylinder provides the powerful force required to move and control the excavator’s bucket during digging, loading, and grading tasks.

Boom Cylinder

The boom cylinder is responsible for lifting and lowering the excavator’s boom, providing the main vertical motion of the machine.

Arm Cylinder

The arm cylinder powers the movement of the excavator’s arm, allowing precise digging depth and reach adjustment.

Travel Cylinder

The travel cylinder operates the track tensioning system, maintaining proper track tightness for stable machine movement.

Hydraulic Lines: Oil Pipe, Hose, Oil Suction Hose, & Oil Return Hose

Oil Pipe

Oil pipes are rigid hydraulic lines used to transfer high-pressure fluid between pumps, valves, and cylinders. They are designed to withstand heavy pressure with minimal expansion, ensuring stable flow and accurate system response.

Hose

Hydraulic hoses are flexible lines that connect moving components within the system. They absorb vibration, allow machine articulation, and maintain safe fluid transmission under varying pressure conditions.

Oil Suction Hose

The oil suction hose carries hydraulic oil from the tank to the pump at low pressure. It is built to resist collapse under vacuum conditions and maintain consistent oil flow into the system.

Oil Return Hose

The oil return hose channels hydraulic oil back to the reservoir after use. It operates under lower pressure than supply lines but must resist abrasion and withstand continuous oil flow for system reliability.

Hydraulic Accessories: Hydraulic Breathing Filter, Suction Filter, Return Filter

Hydraulic Breathing Filter

The hydraulic breathing filter (air breather) is installed on the oil tank to balance internal and external pressure. It prevents dust, moisture, and contaminants from entering the hydraulic fluid during air exchange, ensuring system cleanliness.

Suction Filter

The suction filter is placed at the pump inlet to capture larger particles and impurities in the hydraulic oil before they reach the pump. This protects the pump from wear and damage, extending system reliability.

Return Filter

The return filter is located on the return line and removes fine contaminants from the hydraulic oil before it re-enters the tank. It plays a critical role in maintaining oil cleanliness and preventing component wear across the entire system.

Hydraulic System Maintenance Tips

Keeping your XCMG excavator’s hydraulic system in good condition ensures reliable performance and prevents costly repairs. Below are key areas to monitor and preventive practices to follow.

Common Issue Identification

Slow Operation Symptoms
If the excavator responds sluggishly, it may indicate pump wear, low fluid levels, or valve blockages. Early inspection helps avoid further system damage.
Hydraulic Leaks Detection
Look for oil spots under the machine, damp hoses, or pressure drops. Leaks often come from worn seals, loose fittings, or damaged hoses.
Unusual Noises Diagnosis
Whining, knocking, or rattling noises in the hydraulic system can signal cavitation, air in the system, or failing components. These should be addressed promptly.
Overheating Causes
High hydraulic fluid temperature reduces efficiency and damages seals. Common reasons include low oil levels, clogged filters, or overworked pumps.

Preventive Maintenance Recommendations

Regular Filter Replacement Schedules
Change suction, return, and breathing filters on time to keep contaminants from entering the system.
Proper Hydraulic Fluid Selection
Use fluids that meet XCMG specifications to ensure correct viscosity and temperature performance.
System Contamination Prevention
Keep fill caps, hoses, and connections clean during service. Even small particles can shorten component life.
Seasonal Maintenance Checklist
Adjust fluid types for hot or cold climates, check hoses for weather-related wear, and confirm system pressure matches seasonal requirements.

FAQs of XCMG Excavator Hydraulic Parts

How often should I replace hydraulic filters on an XCMG excavator?

Most filters should be replaced every 500–1000 working hours, depending on machine usage and operating conditions. Always follow the XCMG service manual for exact intervals.

Can I use non-XCMG hydraulic pumps or valves as replacements?

While aftermarket parts may fit, genuine or OEM-quality parts are recommended to ensure compatibility, efficiency, and long-term reliability.

What type of hydraulic oil should I use?

Use hydraulic fluids that meet XCMG’s specified viscosity and performance standards. Choosing the wrong oil can cause overheating, cavitation, or reduced system efficiency.

What are signs of a failing hydraulic pump?

Common symptoms include slow digging speed, reduced lifting power, unusual whining noises, or excessive system heat.

How can I prevent hydraulic leaks?

Regularly inspect hoses, seals, and fittings. Replace worn or cracked hoses immediately, and avoid over-tightening connections which may damage seals.

Are hydraulic cylinders repairable, or must they be replaced?

Most cylinders can be repaired with seal kits or by replacing rods/barrels if damaged. However, severe wear or scoring may require full replacement.

Do hydraulic parts require seasonal maintenance?

Yes. Cold weather may require low-temperature hydraulic oil, while high temperatures call for fluids with higher viscosity stability. Seasonal checks help prevent downtime.
