Doosan excavators, like other heavy equipment, require regular maintenance to ensure optimal performance and longevity. Here is a list of some common Doosan excavator parts that require maintenance:
Engine
The engine is the heart of the excavator and must be regularly serviced. This includes changing the engine oil and filter, checking the coolant level, and inspecting the air filter for cleanliness.
Hydraulic system
Hydraulic components such as pumps, valves, cylinders, and hoses require regular inspection for signs of wear, leaks, or damage. Hydraulic fluid levels should also be checked and maintained.
Undercarriage
Inspect and maintain the undercarriage components, including track chains, track shoes, rollers, idlers, and sprockets. Look for signs of wear or damage, and keep the undercarriage clean to prevent premature wear.
Swing components
The swing drive, swing motor, and swing bearing all need regular inspections and lubrication to ensure smooth operation.
Boom, arm, and bucket
Inspect the pins, bushings, and cylinders of these components for signs of wear, and lubricate them as needed. Check for loose or damaged bucket teeth and replace them if necessary.
Cab
Keep the operator’s cab clean and free of debris, and inspect the door and window seals for damage. Ensure all gauges, switches, and controls are functioning properly.
Electrical system
Check the battery for proper voltage and clean the battery terminals. Inspect the wiring for signs of wear, chafing, or damage, and check all fuses, relays, and circuit breakers.
Cooling system
Inspect the radiator, hoses, and coolant reservoir for leaks or damage, and keep the cooling system filled with the correct coolant mixture.
Greasing points
Regularly grease all necessary components, such as pins, bushings, and bearings, to reduce wear and extend component life.
Fuel system
Inspect the fuel lines, fuel filter, and fuel tank for damage, and replace the fuel filter as needed.
