HYUNDAI R210LC-7 R220LC-7 hydraulic pump

The exact hydraulic pump model for Hyundai R210LC-7 and R220LC-7 excavators might vary slightly depending on the specific year of manufacture and regional variations. However, here's a general breakdown of the most likely pumps used

Possible Pump Models

Kawasaki K7V series This is a common family of axial piston pumps used in excavators of this size class. Specific models within the K7V series could be

K7V152D (displacement 152 ccrev)

K7V190D (displacement 190 ccrev)

Displacement The displacement refers to the amount of hydraulic fluid the pump can deliver per revolution. The R220LC-7, being a slightly larger excavator, might utilize a pump with a higher displacement like the K7V190D compared to the R210LC-7.

Verifying the Exact Pump Model

Here are ways to confirm the specific pump model for your excavators

Operator's Manual The manuals for both Hyundai R210LC-7 and R220LC-7 excavators should list the exact hydraulic pump model number and specifications.

Parts Diagram or Decal The pump itself might have a data plate or decal with the model number.

Contacting Hyundai or a Qualified Technician If unsure about the model numbers, contact your local Hyundai dealer or a qualified technician specializing in Hyundai excavators. They can identify the specific pump based on your excavator information (model year, serial number, etc.).

Additional Information

Functions Powered by the Hydraulic Pump The hydraulic pump is the heart of the excavator's hydraulic system. It converts engine power into high-pressure hydraulic fluid that gets distributed throughout the system to power various functions like

Arm and bucket movement

Track drive

Blade control (if equipped)

Attachment operation (breakers, augers, etc.)

Hyundai Parts Website or Authorized Distributors You can find information about Hyundai parts through their official website or authorized distributors. These resources might have parts diagrams or searchability to help identify the exact pump for your excavators.

Maintenance

Regular maintenance is crucial for optimal performance and longevity of the hydraulic pumps. Refer to the operator's manuals for specific intervals on oil changes, filter replacements, and fluid level checks.

Replacement

Genuine or High-Quality Equivalent When replacing the pump, consider a genuine Kawasaki K7V series pump (depending on the confirmed model) or a high-quality equivalent from a reputable manufacturer. Non-genuine replacements can compromise performance, reliability, and safety.

Qualified Technician Consult a qualified technician for pump replacement, as it involves specialized tools and procedures.

Safety Precautions

Hydraulic systems operate at high pressures and can cause serious injuries if not handled properly. Always follow safety procedures when working on the hydraulic system

Depressurize the system before any maintenance or repairs.

Wear appropriate PPE (gloves, safety glasses, sturdy footwear).

Consult qualified technicians for complex procedures.

By following these tips, you should be able to identify and maintain the hydraulic pumps in your Hyundai R210LC-7 and R220LC-7 excavators.
