Boom Cylinder - Hydraulic cylinder mounted between the excavator body and boom, controls boom movement. Example: Hitachi ZX890LCH-5A boom cylinder
Arm Cylinder - Hydraulic cylinder installed between boom and arm, controls arm extension. Example: Hitachi ZX890LCH-5A arm cylinder
Bucket Cylinder - Hydraulic cylinder mounted on the arm, controls bucket curling action. Example: Hitachi ZX890LCH-5A bucket cylinder
Travel Device - Complete assembly including motors and reduction gears for excavator movement. Example: Hitachi ZX240-5A travel device
Control Valve - Hydraulic valve block typically located near the hydraulic tank, directs hydraulic flow. Example: Hitachi ZX870-5G control valve
Drive Motor - Hydraulic motor mounted in the travel device, powers track movement. Example: Hitachi ZX400LCH-5A drive motor
Swing Device - Assembly including swing motor and gearbox for upper structure rotation. Example: Hitachi ZX170LC-5A swing device

The Hitachi 6HK1 engine is a robust diesel powerplant specifically designed for heavy construction equipment like the ZX360-5A excavator. This engine features advanced fuel injection technology, durable construction, and optimized power output for demanding excavation work. The part number YA00023717 and YA00023717 identifies the complete engine assembly or major components that ensure reliable performance in various operating conditions.
Proper maintenance of the 6HK1 engine includes regular oil changes, fuel filter replacement, and monitoring of cooling system components to prevent overheating. SWAFLY provides genuine replacement parts that maintain the original equipment specifications and performance standards.
Problem: Hitachi ZX330-5A Excavator Hydraulic System Overheating
Symptoms: Reduced digging power, slow operation, hydraulic oil temperature warning light, noticeable burning smell from hydraulic oil
Cause Analysis: This common issue in excavators often results from contaminated hydraulic oil, clogged hydraulic oil cooler, failing hydraulic pump, or restricted hydraulic filters. In the ZX330-5A model, the main control valve (part YA00000734) can develop internal leaks that generate excess heat.
Solution:
Check and replace hydraulic filters (use genuine Hitachi replacements)
Clean the hydraulic oil cooler fins and ensure proper airflow
Test hydraulic oil quality - replace if contaminated or degraded
Inspect the main hydraulic pump for internal wear
Check the control valve YA00000734 for internal leakage
Verify proper operation of the hydraulic cooling fan system
Regular maintenance using quality excavator hydraulic components from SWAFLY can prevent these issues and extend equipment life.
