ZE485E‑10‑5116 — Manufactured Oct 2020 | 5,363 hours | Parked in Xi’an | Bucket assembly missing

Brief overview

• Model/ID: ZE485E‑10‑5116
• Manufacturing date: October 2020
• Hours: 5,363 (high)
• Location/status: parked in Xi’an
• Configuration: bucket assembly not present

Main risks and concerns

• High hours (>5k): increased wear on engine, hydraulic pumps, swing and travel gearboxes, and undercarriage—major components may be near or past expected service life. Obtain records of any major overhauls/replacements.
• Missing bucket: you cannot fully load-test the boom/arm/hydraulic circuits; the bucket may have been removed for repair, sale, or theft—confirm why and whether mounting hardware, pins, coupler parts or hoses are missing.
• Parked condition: long idle storage risks include battery drain, oil/fuel contamination, seal hardening, hose deterioration and surface corrosion. Xi’an’s dusty environment can cause clogged air and hydraulic filters.
• Potentially high repair costs: items such as main pumps, swing or travel gearboxes, or engine rebuilds are expensive.

Priority pre-purchase inspections (must do)

1. Documentation/history: verify VIN/engine numbers; request full maintenance, repair and overhaul records; check for accidents or liens.
2. Reason for missing bucket: confirm whether the bucket is removed for repair, sold separately, or missing/stolen; check if pins, quick‑coupler parts and hydraulic lines are included.
3. Start and functional tests: cold and hot starts; operate boom/arm/rotation/travel—if no bucket available, ask seller to demonstrate with a temporary weight or other attachment. Note smoke, noises, temperature and oil pressure behavior.
4. Hydraulic system: inspect for external leaks, hose condition, cylinder rod damage; inspect hydraulic oil color/odor and tank for contaminants; perform pressure and flow tests to assess pump condition.
5. Oil sampling (strongly recommended): take lab samples of engine oil, hydraulic oil and final drive oils to check wear metals, water, fuel dilution and contamination—critical to assess internal wear and need for major repairs.
6. Undercarriage: measure wear on chain links, shoes, sprockets, rollers and idlers and estimate remaining life; calculate replacement cost if heavily worn.
7. Swing and travel gearboxes: check for play, noise, leaks and internal condition.
8. Boom/arm/pin & bushing inspection: measure pin/bushing play, look for cracks, weld repairs or excessive wear.
9. Engine and exhaust: check turbo/injectors, look for heavy smoke (black/blue/white), coolant condition and radiator cleanliness.
10. Electrical and controls: read fault codes, check joystick responsiveness, gauges, AC/heater and battery condition.
11. Structure: inspect for major collision repairs, welds and integrity of chassis and superstructure.

Typical high‑cost items for a machine with these hours

• Main hydraulic pump or pump system rebuild/replacement
• Swing or travel gearbox repairs or replacement
• Engine major overhaul (if oil samples show high wear or contamination)
• Full undercarriage replacement or major refurbishment
• Cost to purchase and fit a replacement bucket and missing accessories

Recommended next steps

• Ask seller for: high‑resolution photos (engine bay, hydraulic tank fill area, boom/arm pin locations, swing area, undercarriage closeups), short videos (start, idle, and boom/arm/rotation/travel operation), maintenance and repair records, and explanation for the missing bucket.
• Arrange third‑party on‑site inspection including hydraulic pressure/flow testing and oil sampling for laboratory analysis.
• If considering purchase, perform functional tests with a temporary bucket or weight to confirm behavior under load.
• Get quotes for a replacement/matching bucket and estimated costs for any identified repairs; factor these into negotiation.
