Technical Specifications

OEM Cross-Reference

This hydraulic pilot pump is designed as a direct replacement for specific OEM pump models. While the exact OEM part number may vary by manufacturer, this unit is engineered to match the specifications of the following pump models:

• K3V112DPP – Main pump model designation
• K3V112-4 – Alternative pump model designation
• SK200-8 – Excavator model application

Note: Please verify your existing pump model (stamped on the pump housing) to ensure compatibility. This is a pilot pump, which is the smaller gear pump mounted on or near the main hydraulic pump.

Compatibility

This hydraulic pilot pump is commonly used for the following applications:

• Engine Models: Designed to work with diesel engines powering excavators like the SK200-8 series.
• Vehicle/Equipment Applications: Primarily used in Kobelco SK200-8 excavators and other heavy machinery utilizing the K3V112 series main pump.
• Industry Use: Construction, Mining, Agriculture, and Material Handling equipment.

Disclaimer: Compatibility is inferred based on the model numbers provided. We recommend cross-referencing your original pump’s part number for absolute confirmation.

FAQ

Q1: How can I confirm this pilot pump fits my excavator?
A: First, locate the model plate on your main hydraulic pump. Look for the model number (e.g., K3V112-4 or K3V112DPP). This pump is specifically designed for these main pump models. If your main pump model matches, this pilot pump is the correct replacement. You can also check the pilot pump itself for a part number.

Q2: What is the difference between a main pump and a pilot pump?
A: The main pump provides high-pressure oil to operate the main functions (arm, boom, bucket, travel). The pilot pump (like this one) is a smaller gear pump that provides lower-pressure oil to the control joysticks and pedals. This pilot pressure is used to precisely control the main control valves, making operation smooth and effortless. A faulty pilot pump can cause jerky or unresponsive controls.

Q3: What maintenance is required for this hydraulic pilot pump?
A: The most important maintenance is ensuring a clean hydraulic fluid supply. Always use the correct grade of hydraulic oil and replace filters as recommended by your excavator’s manual. Before installation, prime the pump by filling it with clean oil to prevent dry start damage. Regularly check the pilot pressure at the test port to ensure the pump is performing within specifications (typically 30-50 bar, but check your service manual).
