5 Key Steps to Extend the Life of Wheel Loader

As the core power source of construction machinery, the health of the engine directly determines the service life and operational efficiency of the wheel loader. LuGong machinery combined with many years of experience in the industry, for you to summarize the following five key maintenance steps, to help you easily extend the life of the equipment, reduce maintenance costs.

1. Regular replacement of oil and filters

Oil is the core of the engine, which needs to be replaced in strict accordance with the cycle:

Replacement cycle: every 200 hours or quarterly replacement, shortened to 150 hours under poor working conditions.
Operation points: choose the original recommended type of oil, synchronized replacement of oil filters to ensure that impurities and metal shavings and other effective filtration.

2. the depth of air filter maintenance

dust is the engine’s “invisible killer”, air filter cleaning is essential:
check frequency: every 50 hours to clean up the filter element, dust accumulation of more than 50% immediately wash or replace.
Cleaning method: tap or low-pressure airflow reverse blowing, to avoid washing damage to the filter paper structure.
Extreme environment: mines, gravel quarries and other dusty areas, it is recommended to install pre-filtering devices.

3. Fuel System Fine Maintenance

Fuel quality directly affects engine performance and emissions:

Filter Replacement: Replace the fuel filter every 200 hours to prevent impurities from clogging the injector nozzles.
Fuel tank management: Discharge the accumulated water in the oil-water separator before daily operation to avoid water mixing into the fuel.
Fuel selection: use national standard diesel fuel, switch to low condensation point oil (such as -10# diesel) in winter to prevent waxing.

4. the cooling system maintenance

engine overheating will accelerate the aging of components, the cooling system needs to focus on:

Coolant management: every 2000 hours or half a year to replace the antifreeze, the freezing point needs to be adapted to the lowest local temperature (recommended in winter -25 ° C or less).
Radiator cleaning: Clean the dust accumulated in the radiator every month to avoid airflow obstruction triggering high temperature alarm.
Water pump inspection: check the sealing of the water pump every 500 hours to prevent water leakage leading to insufficient coolant.

5. Ignition system and daily operation specification

From operation habit to parts maintenance, all-round guarantee the stable operation of the engine:
Ignition system check: clean the spark plug every 200 hours, adjust the electrode gap to 0.7-0.9mm to ensure the ignition efficiency.
Operation standardization: avoid prolonged overload operation, stop the machine immediately to cool down when the water temperature of the instrument panel exceeds 95℃.
Seasonal adjustment: install preheating device in winter, and clean the air conditioner condenser regularly in summer to adapt to the environmental needs.
