It is a crucial step to keep the excavator hydraulic pump clean to maintain optimal performance and lifespan. Regular cleaning helps prevent extra expenses such as repair or replacement costs, while also ensuring the reliable operation of the hydraulic system. In this article, we’ll provide you with effective cleaning tips.
What is an excavator hydraulic pump?
The hydraulic pump is the core component responsible for powering hydraulic operations in excavators, enabling functions like digging, loading, and lifting. Thus, maintaining the pump’s proper functioning is essential for the excavator’s performance and operations.
How to clean the excavator hydraulic pump?
Step 1: Preparation
Turn off the excavator’s engine and ensure the hydraulic system is depressurized. And refer to the excavator’s manual to locate the hydraulic pump and understand relevant operational details.
Step 2: Surface dirt removal
Use a clean cloth or brush to remove dust, oil stains, and debris from the hydraulic pump’s surface.
Importantly, ensure that no external dirt enters the pump’s internals during the cleaning process.
Step 3: Disassembly of the hydraulic pump
Refer to the excavator’s manual or seek guidance from hydraulic pump suppliers or shops to disassemble the pump. Because it may involve disconnecting piping, bolts, and support structures.
Step 4: Internal cleaning
Use an appropriate cleaning agent, such as mineral oil or specialized cleaners, to wash the internal components of the hydraulic pump. You can apply the cleaning agent evenly using a spray gun or brush, avoiding direct spraying on critical components like seals and bearings.
Step 5: Flushing the hydraulic pump
Rinse the hydraulic pump’s internals thoroughly with clean water or compressed air to remove traces of cleaning agents and dirt. Please ensure thorough cleaning to prevent adverse effects on the hydraulic system.
Step 6: Drying and inspection
Place the hydraulic pump in a well-ventilated area to air dry naturally. Avoid using high temperatures or strong winds for accelerated drying.
Before reassembly, carefully inspect all pump components for damage, wear, or looseness.
Step 7: Reinstallation of the hydraulic pump
Follow the excavator’s manual instructions to correctly reassemble the hydraulic pump. Ensure proper installation of piping and support structures, tightening bolts securely.
