HYUNDAI R140W-7 R160W-7 excavators pump

The Hyundai R140W-7 and R160W-7 excavators  use a Kawasaki K3V series hydraulic pump as their main hydraulic pump. While the exact model variant might differ, the K3V series is a common choice for excavators in the 14-ton to 18-ton size class, which aligns with these Hyundai models. Here's a breakdown of the K3V series and its suitability for these excavators

K3V Series Hydraulic Pumps

Displacement Various displacement options available, typically ranging from 80 to 140 cubic centimeters per revolution (ccrev)

Control Type Can come in single flow path (S) or dual flow path (DTP) configurations. Single flow path provides control for one hydraulic circuit, while dual flow path allows for independent control of two circuits.

Pressure Rating High-pressure rating (specific value varies depending on the model, but likely around 35 MPa or 5076 psi)

Why K3V Series is a Good Fit for Hyundai R140W-7R160W-7

Size Class Match The K3V series offers a range of displacements suitable for the hydraulic power requirements of 14-ton to 18-ton excavators.

Control Options Depending on the specific model (S or DTP), the K3V pump can cater to either a single or dual hydraulic circuit configuration used in these excavators.

Identifying the Exact Pump Model

While the K3V series is a strong possibility, it's crucial to verify the exact hydraulic pump model in your specific excavator. Here's how

Operator's Manual Refer to the operator's manual for your Hyundai excavator. It should have a specifications section listing the model number of the hydraulic pump.

Data Plate The hydraulic pump itself might have a data plate with the model number and other information. Locate this plate on the pump housing.

Hyundai Dealership Contact a Hyundai dealership with your excavator's model and serial number. They can help identify the specific hydraulic pump used in your machine.

Examples of Possible K3V Pump Models

K3V112 series (displacement of 112 ccrev) is a common option for excavators in this size class. It might be a single flow path (S) or dual flow path (DTP) variant depending on the specific hydraulic circuit configuration.

K3V80 series (displacement of 80 ccrev) is another possibility, especially if the excavator has a single hydraulic circuit.

General Maintenance Tips

Regardless of the specific K3V model variant, here are some general maintenance tips to ensure optimal performance and longevity

Regular Oil Changes and Filter Replacements Follow the recommended intervals in the operator's manual and use high-quality hydraulic oil.

Fluid Level Checks Regularly check the hydraulic fluid level according to the markings on the reservoir.

Leak and Damage Inspection Look for leaks, loose connections, or visible damage on the pump housing and surrounding components. Address any issues promptly.

By following these verification and maintenance practices, you can ensure the proper functioning of the hydraulic pump in your Hyundai R140W-7 or R160W-7 excavator.
