Caterpillar air compressor 0R-4740 is a key component in Caterpillar equipment pneumatic systems, responsible for compressing atmospheric air into high-pressure air (typically 8-10 bar) to power critical functions like brake systems, hydraulic controls, and tool operation. Its stable air supply is essential for the safe and efficient operation of machinery in construction, mining, and transportation applications. Ningbo Qiuning Trading Co., Ltd., a professional supplier, offers both genuine and aftermarket versions to meet diverse operational needs.
In terms of performance, the compressor features a robust reciprocating or rotary design with precision-machined cylinders and pistons, ensuring high volumetric efficiency (≥85%) and low energy consumption. It is constructed with wear-resistant materials (cast iron components, stainless steel valves) to withstand continuous operation and resist corrosion from moisture in the air. The integrated cooling system (air or water-cooled) prevents overheating, maintaining stable output even during prolonged use (up to 12 hours of continuous operation). Its compact structure allows for easy integration into the equipment’s engine compartment without compromising airflow.
For compatibility, 0R-4740 is specifically engineered for certain Caterpillar models, matching original mounting dimensions, drive system specifications, and air outlet connections. This ensures seamless installation, with a perfect fit that guarantees optimal alignment with the engine’s drive belt or gear system, preventing premature wear. It works seamlessly with Caterpillar air dryers, filters, and storage tanks, maintaining the integrity of the entire pneumatic system.
Ningbo Qiuning Trading Co., Ltd. provides genuine air compressors that adhere to Caterpillar’s strict quality standards, undergoing rigorous testing for pressure output, durability, and leak resistance—ideal for applications where reliability is paramount. Aftermarket compressors, produced by reputable manufacturers with advanced manufacturing technology, replicate the genuine part’s performance and fit at a competitive price, offering a cost-effective solution for maintenance and replacements.
Our professional team assists with model verification to ensure the compressor fits your Caterpillar equipment. Whether for heavy-duty operations or routine maintenance, we deliver quality components. For inquiries or orders, contact:

The main function of the Carter oil filter is to filter the engine oil, improve its cleanliness and lubrication,. Supplying the crankshaft, connecting rod, camshaft, turbocharger, piston rings and other moving parts with clean engine oil plays a role in lubrication, cooling, and cleaning, thereby reducing engine wear, enabling them to perform at their best, and extending the life of these components.

Like the blood circulation system of the heart, the oil in the oil pump is constantly circulating, and in this process, many unexpected impurities are often produced, which need to be filtered by the oil filter.
