To keep your used CAT 320C excavator running at peak performance, pay attention to these maintenance considerations. Monitor the operator display regularly; common issues include connector corrosion or loose wiring harnesses, often resolved by checking the monitor connector behind the side panel. For hydraulic system efficiency, check pump regulators and servo control spools periodically to prevent engine overloading issues. Low engine oil pressure warnings typically indicate oil pump, line leakage, or low oil level issues. Cooling system efficiency requires regular radiator inspection to avoid high coolant temperature warnings. Maintaining hydraulic oil levels and cooling systems prevents high hydraulic oil temperature warnings. Richreach provides thorough pre-delivery inspections and maintenance records.
When comparing the used Cat 320C vs Cat 320D, consider these key differences: The 320C uses direct injection technology and is more tolerant of varying fuel quality, making it ideal for regions with less consistent fuel supply. The 320C is renowned for its stability, reliability, and durability, especially suited for heavy-duty applications. The 320C offers a longer arm with a smaller bucket (0.9 m³ standard bucket), while the 320D features a shorter arm with a larger bucket. The 320C uses the Cat 3066 engine with slightly lower power output, while the 320D uses the Cat C6.4 ACERT engine. The 320C is better suited for users prioritizing stability and long-term durability, while the 320D is designed for those seeking higher efficiency and advanced operating features. Richreach can help you evaluate which model best fits your specific needs.
Proper transport planning requires accurate CAT 320C weight and dimension data. Standard operating weight is 49,200 lbs (22,300 kg) with standard undercarriage. The Utility variant has increased weight due to the 70% heavier counterweight, ranging up to 50,700 lbs (23,000 kg). Transport width is 121.26 inches (3,080 mm). Track shoe widths are available in 600 mm, 700 mm, and 800 mm options. Richreach can assist with shipping arrangements and documentation for international delivery.
