The Hitachi ZX200 is one of the most respected mid-sized excavators in the construction industry. Known for its powerful performance, fuel efficiency, and exceptional durability, this 20-ton class machine has earned a reputation as a reliable workhorse across job sites worldwide. However, when purchasing a used excavator, even a legendary model like the Hitachi ZX200 requires thorough inspection to ensure you’re making a sound investment.
This guide walks you through the five critical inspection areas you must evaluate before committing to a purchase. Whether you’re considering a used Hitachi ZX200 for urban construction, infrastructure projects, or fleet expansion, these checks will help you avoid costly surprises and secure a machine that delivers long-term value.
1. Engine System: The Heart of the Hitachi ZX200
The engine is the most expensive component to repair or replace on any used excavator. For the Hitachi ZX200, which is typically powered by a reliable Isuzu diesel engine, a thorough engine inspection is non-negotiable.
What to Check:
Cold Start Performance: Request a video of the machine starting from cold. A healthy Hitachi engine should start smoothly without excessive white or black smoke. Difficulty starting or excessive smoke often indicates worn injectors, compression issues, or fuel system problems .
Engine Oil and Leaks: Inspect the engine compartment for any signs of oil leakage. According to Hitachi workshop manuals, even small leaks can escalate into major issues. Check for oil leaks due to missing or loose clamps, kinked hoses, or lines that rub against each other .
Exhaust Color:
- Black smoke: Indicates incomplete combustion—often due to clogged air filters, faulty injectors, or turbocharger issues
- Blue smoke: Signals burning oil—a sign of worn piston rings or valve seals
- White smoke: Suggests coolant entering the combustion chamber—potentially a blown head gasket
Operational Performance: Ask the seller to demonstrate the machine under load. The engine should maintain consistent RPMs without bogging down when hydraulic functions are activated.
Red Flags to Watch For:
- Difficulty starting or excessive cranking
- Visible oil leaks around the engine block or turbo
- Unusual knocking or tapping noises
- Coolant level consistently low (possible internal leak)
2. Hydraulic System: The Power Behind the Performance
The hydraulic system is what gives the Hitachi ZX200 its legendary digging force. Hitachi’s ZAXIS hydraulic technology delivers impressive fuel economy and swift front movements . However, hydraulic components are expensive to repair, making this a critical inspection area.
What to Check:
Hydraulic Oil Leaks: Walk around the machine and inspect all hydraulic hoses, cylinders, and connections. Look for:
- Wet spots or drips around hose fittings
- Kinked or chafing hoses that could fail under pressure
- Damage to the oil cooler or loose oil-cooler flange bolts
Hydraulic Pump Health: The main hydraulic pump is the heart of the system. According to technical manuals, the main pump delivery pressure should be measured with the engine at fast idle and hydraulic oil temperature maintained at 50±5°C (122±9°F) . Ask the seller for:
- Pump pressure test results
- Any history of pump repairs or replacement
- Operational tests showing boom, arm, and bucket speed
Cylinder Performance: Check each hydraulic cylinder for:
- Smooth, consistent extension and retraction
- No jerky movements (indicates air in system or internal leakage)
- Absence of oil stains on cylinder rods (indicates worn seals)
Common Hydraulic Issues: The Hitachi ZX200 can experience hydraulic pump noise if the system is drawing air, or weak digging force if components like the piston, cylinder block, or valve plate are excessively worn .
Red Flags to Watch For:
- Oil puddles under the machine after running
- Slow or weak hydraulic functions
- Unusual whining or grinding noises from the pump
- Hydraulic oil that appears milky (water contamination) or contains metal particles
3. Undercarriage and Structural Components
The undercarriage is one of the most expensive wear items on any used excavator. For the Hitachi ZX200, a worn undercarriage can cost $5,000–$10,000 to replace, making this inspection crucial for your total cost calculation.
What to Check:
Track Chains: Measure the track sag between the carrier roller and the track shoe. Excessive sag indicates chain stretch. Also check for:
- Rust between bushings (indicates prolonged sitting)
- Worn or broken track links
- Missing track shoes or bolts
Sprockets and Idlers: Inspect the drive sprockets for sharp, hooked teeth—a clear sign of advanced wear. The front idlers should show no excessive wear on the contact surfaces.
Rollers: Check all bottom rollers and carrier rollers. Look for:
- Rollers that don’t turn freely (seized bearings)
- Flat spots or excessive wear
- Oil leaks from rollers (indicates seal failure)
Track Frame and Main Frame: Walk around the machine and inspect the frame for:
- Cracks or welding repairs (especially around the turntable connection)
- Signs of impact damage
- Corrosion or rust-through in structural areas
Turntable Bearing: This critical component allows the upper structure to swing. Check for:
- Excessive play when swinging
- Grease leaks from the bearing seal
- Unusual grinding noises during rotation
Red Flags to Watch For:
- Track chains that have been “flipped” multiple times (reduced life remaining)
- Visible cracks in the track frame
- Rust bleeding from the turntrace bearing (indicates internal wear)
4. Operational Performance: Swing, Travel, and Digging Functions
Beyond static inspections, you need to verify that the Hitachi ZX200 performs as expected under operating conditions. This is where many hidden issues reveal themselves.
What to Check:
Travel Performance: According to Hitachi service manuals, proper travel speed and track revolution speed are key performance indicators . Test:
- Travel speed: Both tracks should move the machine at consistent speeds in forward and reverse
- Mistrack check: Drive the machine forward in a straight line. If it consistently veers to one side without operator input, there may be a hydraulic imbalance
- Travel parking leakage: After stopping on a slope, the machine should hold position without drifting
Swing Performance: The swing function should be smooth and responsive. Check:
- Swing speed (should be consistent in both directions)
- Swing function drift—if the upper structure continues moving after you return the lever to neutral, there may be swing motor or brake issues
- Swing motor leakage—excessive internal leakage reduces swing power and creates heat
Digging Functions: Test each function individually:
- Boom raise and lower
- Arm (stick) roll-in and roll-out
- Bucket curl and dump
Check for hydraulic cylinder cycle time—slow cycles indicate worn pumps or internal leakage . Also perform a dig function drift check: position the bucket against an immovable object and observe if it holds position or slowly drifts .
Combined Operations: Test simultaneous functions like boom raise and swing, or boom raise and arm roll-in. Smooth combined operation indicates a healthy hydraulic system .
Red Flags to Watch For:
- Travel veering to one side
- Slow or weak swing function
- Hydraulic drift under load
- Jerky or unresponsive controls
5. Electrical System and Cab Condition
While often overlooked, electrical issues can be frustrating and expensive to diagnose. The Hitachi ZX200 uses electronic controls for engine management and hydraulic optimization, making a thorough electrical inspection essential.
What to Check:
Wiring and Connections: Hitachi workshop manuals emphasize checking before each shift for loose, kinked, hardened, or frayed electrical cables and wires . Inspect:
- Wiring harnesses for chafing or damage
- Battery cables for corrosion
- Terminal caps—missing or damaged caps can lead to short circuits
Monitor Panel: The ZX200’s monitor panel displays critical machine data. Check that:
- All warning lights illuminate briefly when starting
- No active error codes are displayed
- Hour meter reading appears consistent with machine condition
Cab Controls: Test all cab functions:
- Air conditioning and heating
- Seat adjustments and seat belt
- Wiper and washer
- Work lights
- Horn and backup alarm
Computer and Sensors: Electrical issues can manifest as:
- Intermittent power loss
- Erratic throttle response
- Warning lights that stay illuminated
Red Flags to Watch For:
- Rat’s nest of aftermarket wiring
- Corroded fuse box or relays
- Warning lights that don’t illuminate during startup (may indicate tampering)
- Non-functional gauges or display issues
