Excavator parts daily maintenance and repair skills

The excavator worked hard with the operator on weekdays and carried out construction work in various places. After the construction of the excavator, maintenance and maintenance are also required to maintain the equipment with sufficient power and efficient operation performance. What problems should the excavator pay attention to during daily use, and what should be paid attention to during maintenance? Let's talk about the things that excavator maintenance skills do!

1. Daily maintenance: check, clean or replace the air filter, clean the inside of the cooling system, check and tighten the track plate bolts, check and adjust the track tension, check the excavator intake heater, replace the teeth, adjust the excavator shovel Fight. Clearance, check the front window cleaning fluid level, check and adjust the excavator air conditioner, clean the cab floor, and replace the breaker filter (optional). When cleaning the inside of the cooling system, slowly loosen the engine after it has cooled down sufficiently. The water inlet cover releases the internal pressure of the water tank before releasing the water. Do not perform cleaning when the engine is working. The high-speed rotating fan may cause danger. When cleaning or replacing the coolant, the machine should be parked on the level ground. 3 Replace the coolant and corrosion inhibitor.

2. Check items before starting the engine: check the level of the liquid level of the excavator coolant (add water), check the engine oil level of the excavator engine, add the oil, check the fuel level of the excavator (fueling), check the hydraulic oil Bit (plus hydraulic oil), check if the air filter is clogged, check the wires, check if the horn is normal, check the lubrication of the bucket, check the water and sediment in the water separator.

3, every 100h maintenance items: excavator boom cylinder pin shaft, boom foot pin, boom cylinder rod end, arm cylinder pin shaft, boom, stick connecting pin, arm cylinder rod End, bucket cylinder head pin, half rod connecting rod, stick, bucket cylinder rod end, bucket cylinder head pin, arm connecting rod connecting pin, check the oil level in the swing mechanism box (Add oil) to drain water and sediment from the fuel tank.

4. Every 250h maintenance project: After the new excavator works for 250h, the fuel filter and the additional fuel filter should be replaced to check the clearance of the excavator engine valve. Check the oil level in the final gearbox of the excavator (plus gear oil), check the battery electrolyte, replace the oil in the engine oil sump, replace the engine filter, lubricate the slewing ring (2 places), check the tension of the fan belt, Also check the tension of the air conditioner compressor belt and make adjustments.
