3TNV88 400901-00022 Engine Assembly OEM Diagnostic Guide
Use this OEM manual diagnostic guide to troubleshoot operational engine symptoms on your Doosan DH35Z mini excavator:
| Engine Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Hard cold starting & dense white smoke | Mechanical injection pump timing retarded or low compression (<2.8 MPa) in 3 cylinders due to piston ring wear. | Adjust Yanmar injection pump timing or replace with Tatan complete 3TNV88 engine assembly. |
| 2. Severe power loss & black smoke under hydraulic load | Fuel injection pump governor spring fatigue or clogged mechanical fuel injectors causing incomplete combustion. | Inspect fuel injection pressure or swap to a Tatan factory pre-tested 3TNV88 complete engine. |
| 3. High engine oil consumption & heavy crankcase blow-by | Scored 1.6L cylinder liners, stuck oil rings, or valve stem seal wear allowing engine oil into combustion chambers. | Install Tatan new 3TNV88 complete engine; flush engine oil gallery and replace oil filter. |
| 4. Engine overheating & coolant surge into expansion tank | Water pump impeller erosion, clogged radiator core, or cylinder head gasket leaking combustion gas into cooling jacket. | Replace thermostat (82°C), flush cooling system, or swap to a new 3TNV88 complete engine assembly. |
