KO4941143: A worn hydraulic pump can lead to reduced system pressure and sluggish actuator response. The Komatsu catalog reference for this aftermarket replacement part is KO4941143. This pump assembly moves fluid to generate flow for mechanical work. A common failure consequence is that internal wear causes cavitation, which reduces output and may damage downstream components. In a typical usage context, the pump operates continuously under load, making seal integrity critical for sustained performance. This item ships at approximately 7.168 POUNDS.
