6WG1-T 1-11110-877-0 Engine Assembly Overview
The 6WG1-T 1-11110-877-0 Engine Assembly manufactured by Tatan is a heavy-duty 15.681L 6-cylinder turbocharged water-cooled diesel powerplant belonging to our Diesel Engine Assembly classification. Engineered specifically for Hitachi ZX470-5G, ZX470LC-5G, ZX470H, and ZX490-5A 47-49 ton heavy mining excavators, swapping your fatigued powerplant with this complete 6WG1-T 1-11110-877-0 Engine Assembly unit eliminates costly jobsite downtime, severe crankcase blow-by, and hydraulic stall under continuous 47-ton rock breakout cycles.
Built strictly according to original Isuzu OEM specifications, this complete engine assembly is pre-fitted with a high-pressure common rail fuel system, heavy turbocharger, 24V starter motor, and alternator, ensuring 100% direct mechanical alignment with Hitachi dual main hydraulic pump dampener couplings and engine mounting brackets.

Application Scenarios & Buyer Value
When rebuilding or replacing aging powerplants with our 6WG1-T 1-11110-877-0 Engine Assembly, workshops and equipment owners eliminate repetitive downtime:
| Application Scenario | Value Delivered to Buyer |
|---|---|
| Hitachi ZX470 Engine Replacement | Swapping to the 6WG1-T 1-11110-877-0 Engine Assembly cuts machine repair downtime by up to 75% compared to trial-and-error field block rebuilding. |
| Heavy Mining Overhaul Centers | Avoids the high cost and failure rate of line-boring cracked main bearing saddles and grinding undersized crankshafts on high-hour 15.7L blocks under 47-ton loads. |
| Quarry & Hard-Rock Excavation Fleets | Restores full 250 kW high-stall torque, driving dual main hydraulic pumps simultaneously without engine RPM dipping under massive 2.5 m³ bucket penetration. |
| International Machinery Stockists | Ready-to-ship replacement engine inventory for overseas contractors maintaining working fleets of classic 47-ton Hitachi machinery. |
6WG1-T 1-11110-877-0 Engine Assembly OEM Diagnostic Guide
Use this technical diagnostic guide to identify engine failures on your Hitachi ZX470 excavator:
| Engine Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Hard cold starting & dense white unburned fuel smoke | Common rail fuel pressure build-up delayed or cylinder compression falling below 2.9 MPa due to 147 mm piston ring and liner wear. | Adjust injection timing or replace with a complete 6WG1-T 1-11110-877-0 Engine Assembly. |
| 2. Severe RPM drop & heavy black smoke under hydraulic load | Turbocharger wastegate failure leading to low manifold boost pressure (< 1.3 bar) or fuel injection metering valve fatigue. | Inspect turbocharger boost pressure or swap to a factory pre-tested complete replacement engine. |
| 3. Excessive oil consumption & high crankcase blow-by pressure | Scored 15.7L cylinder liners, stuck oil scraper rings, or deteriorated valve stem seals allowing engine oil into combustion chambers. | Install a new complete engine assembly; flush oil cooler lines and replace oil filter cartridges. |
| 4. Engine coolant overheating & continuous radiator bubbling | Water pump impeller cavitation erosion, clogged radiator core tubes, or cylinder head gasket leaking high-pressure combustion gas into the water jacket. | Replace thermostat (82°C), flush cooling system, or install a brand new complete engine unit. |
