The CYL.;BOOM, part number ZA60001971, is a vital component of the hydraulic lifting mechanism on the Hitachi ZX200-5A excavator. The boom cylinder is responsible for raising and lowering the main boom arm, facilitating the heavy lifting and digging operations. Its robust construction ensures it can withstand high pressures and continuous operation cycles. Regular maintenance of the hydraulic seals is crucial to prevent internal leakage, which can lead to a 'boom drift' where the boom slowly lowers under load. Choosing quality replacement cylinders and undercarriage components, like those supplied by SWAFLY, guarantees longevity and maintains the machine's lifting capacity. We also supply the corresponding Arm Cylinder and Bucket Cylinder to complete your excavator's hydraulic overhaul.
Understanding the components of your heavy equipment is essential for effective maintenance and repair. Here are 10 key construction machine components:
Slew Ring/Swing Bearing: A large-diameter rolling-element bearing that connects the undercarriage to the house (cab/boom/engine) and allows for 360-degree rotation.
Example: Caterpillar 345D Swing Bearing Replacement.
Track Adjuster: An assembly located on the undercarriage that maintains proper tension on the track chain to prevent track derailing and excessive wear.
Example: Hitachi ZX350-5 Track Adjuster.
Pilot Pump: A small gear pump, often attached to the main pump, that supplies low-pressure hydraulic oil to the control valves for smooth operation.
Example: Komatsu PC200-8 Pilot Pump.
Final Drive: The gear reduction mechanism (planetary gear set) located in the travel motor assembly that delivers power to the track sprocket.
Example: Volvo EC210 Travel Motor Final Drive Assembly.
Water Pump: Part of the engine assembly responsible for circulating coolant throughout the engine block and radiator to regulate temperature.
Example: Isuzu 6HK1 Engine Water Pump.
Control Valve: The component that directs the flow of hydraulic fluid to the various cylinders and motors based on operator input.
Example: Hitachi YA00000721H3 Control Valve.
Piston Pump: A type of main hydraulic pump that uses pistons to move hydraulic fluid, capable of handling high pressures and variable flow rates.
Example: Kawasaki K3V Series Piston Pump.
Solenoid Valve: An electromechanically operated valve that controls the release or shut-off of hydraulic fluid via an electric current.
Example: Doosan DX225 Solenoid Valve Block.
Turbocharger: An air compressor that increases engine power by forcing more air into the combustion chamber.
Example: John Deere PowerTech 6068 Turbocharger.
Hydraulic Oil Cooler: A radiator-like component that dissipates heat from the hydraulic fluid to maintain optimal operating temperature.
Example: Hyundai R300LC-9 Hydraulic Oil Cooler.
In addition to the Hitachi ZX200-5A Boom Cylinder ZA60001971, SWAFLY maintains a comprehensive stock of Hitachi excavator parts.

Equipment: Heavy Duty Excavator - Komatsu PC300-7
Failure: Slow and Weak Travel Performance, especially when tracking straight, with one track noticeably weaker or not moving.
Root Cause & Analysis: This issue often points to a failure within the travel motor or the main hydraulic control valve block. If one track is completely dead, a sheared shaft in the final drive or a catastrophic failure in the travel motor's rotating group (e.g., pistons or valve plate) is likely. If it's just weak, the issue could be a worn-out relief valve (travel relief valve) in the main control valve, causing pressure loss, or severe contamination and wear in the motor itself.
Solution:
Check the system pressure at the travel motor port; if pressure is low, the relief valve (a component we supply) may need replacement.
If the pressure is good but the motor is weak, flush the system and replace the defective Travel Device.
For catastrophic failures, the entire final drive assembly needs to be disassembled, inspected, and all damaged parts, potentially including the planetary gear set, must be replaced.
Use only high-quality hydraulic seal kits to prevent future leaks during reassembly.
Our commitment is to provide a reliable source for Hitachi and other major brand engineering machinery parts. We offer a wide variety of components including swing bearing replacement, various control valve models, and full engine assembly parts. From the smallest track link assembly pin to a complete cabin assembly, SWAFLY ensures that every part, like the featured ZA60001971 Boom Cylinder, meets rigorous quality standards. We help keep your machines running efficiently, whether you need components for an excavator, bulldozer, or any other heavy machine. Look to SWAFLY for your next replacement excavator parts order.
