Technical Specifications

OEM Cross-Reference

This hydraulic pilot pump is designed as a direct aftermarket replacement for the following OEM pump assemblies. It is commonly used on machines equipped with the K3V140, K3V140DT, and K3V180DT main pumps.

• Main Pump Models: K3V140, K3V140DT, K3V180DT
• Common Applications: Doosan DH280, Doosan DH320, Hyundai R290, Hyundai R330, Volvo EC360
• Note: This is a pilot pump, not the main hydraulic pump. It is typically a smaller gear pump mounted on or near the main pump assembly. Always verify your part number against your original equipment.

Compatibility

This hydraulic pilot gear pump is commonly used for the following excavator models and engine configurations. Fitment is inferred based on common hydraulic system architecture.

• Doosan: DH280, DH320 series
• Hyundai: R290, R330 series (with K3V pump platform)
• Volvo: EC360 series (with K3V pump platform)
• Application: Construction, Industrial, Agriculture, Genset, Marine, Material Handling

Important: Please confirm your machine’s main pump model (K3V140, K3V140DT, or K3V180DT) before purchasing. This pump is not a universal fit and is specific to these hydraulic platforms.

FAQ

Q: How do I confirm this pilot pump fits my excavator?

A: First, identify your machine’s main hydraulic pump model number. This pilot pump is specifically designed for the K3V140, K3V140DT, and K3V180DT pump platforms. Check for a nameplate on your main pump. If your main pump is one of these models, this pilot pump is likely a direct fit. You can also compare the mounting flange and shaft dimensions with your old pump.

Q: What is the function of this pilot pump in the hydraulic system?

A: This gear pump generates the low-pressure hydraulic oil flow (typically 30-50 bar) used for the pilot control system. This system powers the joysticks and pedals that control the main control valves. Without a functioning pilot pump, the machine’s main hydraulic functions will be unresponsive or very difficult to control.

Q: What maintenance is required for this pump?

A: While the pump itself is a sealed unit, its lifespan depends on the cleanliness of the hydraulic oil and the condition of the main hydraulic system. Ensure your hydraulic oil and filters are changed according to the manufacturer’s schedule. Contaminated oil is the primary cause of premature pump failure. Always check the suction line for restrictions or leaks during installation.
