High-Performance Hydraulic Pumps: The Power Source

The hydraulic pump is arguably the most critical component, converting mechanical energy into hydraulic energy. The Kawasaki K3V series is renowned globally for its reliability and performance in demanding applications. These pumps are variable displacement, axial piston pumps, allowing for precise control of flow rate to match the load requirements. They are the driving force behind your excavator's digging, lifting, and pushing capabilities in various environments from standard construction sites to challenging mining operations.

We provide solutions for several K3V pump models, suitable for a range of excavators:

• The K3V-63DT-1R0R-9N01-2A-UK hydraulic pump is found in machines requiring this specific flow and pressure characteristic. A common application is in excavators like the R1300LC, which is often used in medium-scale earthmoving and trenching projects where consistent hydraulic power is needed for efficient operation.

• For larger machines or those with higher flow demands, the K3V280DTH-150R-ZP12-V/AV hydraulic pump and the K3V280DTH-171R-BE0R hydraulic pump are robust options. These are typically used in heavier excavators found in large construction sites, quarrying, or mining, where significant power is required for heavy digging and lifting tasks.

• Mid-range excavators often utilize pumps like the K3V112DT-15ER-CN19-1 hydraulic pump, K3V112DT-16EL-9N19-1 hydraulic pump, and the K3V112DT-1X5R-2NB9-3 hydraulic pump. The S220LC-V hydraulic pump K3V112DT-115R-HN0V (293G415-HN0V) is specifically for the S220LC-V model, a versatile excavator used in general construction, road building, and utility work, requiring balanced power for various attachments.

• The K3V140DT-101L-1P02 hydraulic pump provides the necessary power for excavators that fall into the mid-to-heavy category, capable of handling substantial workloads in demanding environments.

Choosing the correct, high-quality replacement hydraulic pump is crucial for maintaining cycle times, fuel efficiency, and the overall health of your hydraulic system. At Tonkee / PartsDictionary.com, we provide reliable aftermarket solutions for these vital components.

Precision Swing Motors: Mastering Rotation

The swing motor, powered by the hydraulic system, is responsible for rotating the excavator's upper structure (cab and boom) on the undercarriage. This motion is fundamental for loading trucks, positioning the bucket, and maneuvering in tight spaces. A smooth, powerful swing is essential for operational efficiency and safety.

We offer a variety of swing motors and assemblies catering to different excavator models:

• The S340LC-V swing motor TSM-S340LC-V-130426-00014 is designed for the S340LC-V excavator, a powerful machine often used in heavy civil engineering and mining, where smooth and strong swing is needed for efficient material handling.

• For the DX260(CHINA) swing motor assembly 130401-00026, this assembly provides the crucial rotational function for the DX260 model, a common excavator in the Chinese market used across various construction applications.

• The DX255 swing motor TSM-DX255-130401-00026 is tailored for the DX255 excavator, a versatile model used in general construction, road work, and utility projects, relying on precise swing for tasks like trenching and pipe laying.

• Models like the DX140LC and DX140W (wheeled excavator) utilize the DX140LC DX140W swing motor TSM-DX140LC DX140W-K1007357B or the K1007357B Swing Motor Assembly. These excavators are highly adaptable, used in urban construction, road maintenance, and landscaping, requiring responsive swing for maneuverability and fine positioning.

• The JS240 swing motor assembly 05-202200 and the JS260 swing motor TSM-JS240-05-202200 are suitable for the JS240 and JS260 series excavators. These machines are popular for demanding tasks like bulk excavation and demolition, where robust swing performance is essential for productivity and safety.

A failing swing motor can lead to jerky movement, slow rotation, or complete loss of swing function, severely impacting operation. Finding the correct, high-quality replacement swing motor or assembly from Tonkee / PartsDictionary.com ensures your machine can operate at full capacity.

Diesel Engine Parts Glossary:

Beyond the hydraulic system, the diesel engine is the power source for your excavator. Understanding some key engine components can be helpful:

• Fuel Injector: Located in the cylinder head, it atomizes and injects fuel into the combustion chamber. Example: Komatsu PC200-8 Fuel Injector.

• Turbocharger: Mounted on the exhaust manifold, it uses exhaust gases to spin a turbine, forcing more air into the engine cylinders to increase power. Example: Hitachi EX300-5 Turbocharger.

• Piston: Inside the cylinder liner, it moves up and down converting combustion energy into mechanical force. Example: Hyundai R220LC-9S Piston.

• Cylinder Liner: A sleeve fitted into the engine block that forms the cylinder wall for the piston. Example: Doosan DX300LC Liner.

• Crankshaft: Located in the engine block, it converts the linear motion of the pistons into rotational motion to power the machine. Example: Sany SY210 Crankshaft.

• Camshaft: Usually located in the engine block or cylinder head, it has lobes that open and close the engine's intake and exhaust valves. Example: Liugong 922D Camshaft.

• Water Pump: Mounted on the engine block, it circulates coolant through the engine to regulate temperature. Example: Volvo EC210B Water Pump.

• Radiator: Typically located at the front of the machine, it cools the engine coolant using air flow. Example: Kubota KX080-3 Radiator.

• Alternator: Usually belt-driven by the engine, it generates electrical power to charge the battery and run the machine's electrical system. Example: JCB 3CX Alternator.

• Starter Motor: An electric motor that cranks the engine to start it. Example: XCMG XE215C Starter Motor.
