About CAT 320 Excavator
Description
This is a 2021 model Caterpillar 320 excavator. It was recommended to us by a friend of one of our engineers. This friend knew the owner of this excavator very well because the owner of this machine found a new project and no longer needed this excavator. He wanted to sell it as soon as possible. This friend contacted us and introduced the condition of this excavator to us. He told us over the phone that this excavator was in excellent condition. The original owner of the machine had taken very good care of it. So our engineer went there and conducted a detailed inspection of this excavator. It was found to be exactly as he said on the phone. Only then did this excavator have a perfect working condition. So our engineer brought this excavator back to our factory and repaired it, replacing some easily damaged parts to make it now in the same condition as a new one.

Performance characteristics
The Caterpillar 3408 engine is a four-stroke, water-cooled, inline design engine with 8 cylinders, each having a cylinder diameter of 140 mm and a piston stroke of 153 mm. The total displacement is 5.08 liters and the maximum torque can reach 730 Newton-meters. The Caterpillar engine adopts advanced fuel injection technology. The water cooling system of the Caterpillar engine can effectively dissipate excess heat, keeping the engine temperature within the normal range, thereby further improving fuel economy and reliability. The Caterpillar 320 engine also has a good design in terms of heat dissipation and thermal management to ensure the engine operates at the optimal working temperature. The Caterpillar engine uses high-quality materials and component designs, and undergoes strict manufacturing and testing processes to ensure high reliability and long service life. The overall structure and key components of the Caterpillar 320 engine also follow such standards, enabling stable operation in harsh working environments. List the wear-prone components that must be replaced before mechanical transportation.
Maintenance
To ensure that our quality can satisfy customers with peace of mind We will conduct a detailed inspection of each excavator to ensure that it is in good working condition System inspection items and requirements. 1.Appearance and structural inspection requirements: Check the large and small arms for any welding or cracks (signs of refurbishment). 2.Engine system inspection requirements: Engine exhaust, no abnormal noise, no blue smoke, no carbon buildup in the exhaust pipe, no oil leakage in the oil pan, and no noise during idle. 3.Hydraulic system inspection requirements:The hydraulic pump/motor should have no vibration, cracks, or oil leakage, pressure stability, the chrome plating layer of the oil cylinder should have no scratches or oil leakage, the operation should be smooth, and the pipeline should be confirmed to have no bulges or aging. 4.Electrical system inspection requirements: The computer board should display speed, pressure, and fault codes normally.Line: The lighting, air conditioning, and alarm system are functioning properly. 5.Inspection requirements for walking system: Track: The rubber layer has no cracks, the chain rail has slight wear, and the chain number is consistent with the machine Motor: When walking, the speed on both sides is consistent, and the walking is normal 6.Cooling and intake system inspection requirements: The radiator should be clean and free of dust, and the fan tape should not be loose.
