The hydraulic pump is the heart of a concrete pump truck. Operating under high pressure and frequency, its internal parts are subject to wear and fatigue. Replacing components at regular intervals helps prevent sudden failures and costly downtime.

Recommended Replacement Intervals (KAWASAKI K5V Series Reference):

When Should You Replace Parts Earlier?

• Rising oil temperature or noticeable drop in pressure

• Oil leakage or cavitation noise from the pump

• Detected wear, deformation, or looseness during inspection

• Even without failure, preemptive replacement is advised after max service hours

Replacement Tips:

• Replace major parts as a set (e.g., piston + cylinder + valve plate) to ensure uniform wear

• Replace hydraulic oil and filters after installation

• Always choose high-precision, OEM-compatible parts from verified suppliers to ensure performance and longevity
