This is a Kawasaki K3V112DT series hydraulic pump, a critical component responsible for generating the high-pressure fluid flow required to operate the excavator's functions. It converts mechanical energy from the engine into hydraulic energy, powering the boom, stick, bucket, and travel systems. A worn or failed hydraulic pump will result in a significant loss of power, slow or erratic hydraulic movements, and potentially overheating of the hydraulic system.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The most immediate symptom of a failing hydraulic pump is a noticeable decrease in the speed and power of all hydraulic functions. The machine may struggle to lift heavy loads, and movements can become jerky or slow. If left unaddressed, the pump can fail completely, rendering the equipment inoperable and potentially causing severe contamination of the hydraulic system.
Ensure the hydraulic reservoir is filled with the correct type and amount of hydraulic fluid before starting the pump. Never run the pump dry, as this can cause immediate internal damage.
Replace the hydraulic filter and inspect all hydraulic hoses and fittings for leaks or wear when installing a new hydraulic pump.
