The Hitachi 3038090 center shaft is a critical drive component within the main hydraulic pump assembly (HPV116/HPV145 series) used on 20-30 metric ton class hydraulic excavators. It transmits rotational torque from the engine coupling through the pump gear set to generate hydraulic flow.

Manufactured from high-strength alloy steel with precision ground splines and bearing journals, this shaft ensures concentricity and wear resistance under high-pressure operating conditions. It serves as a direct replacement for Hitachi OEM part numbers 3038090 and 3035589. Compatible with Hitachi EX200, EX220, EX270, EX300, EX300-2, EX300-3, EX300LC, LX80RS-2, and RX2000 excavator models.
