CAT C15 Diesel Engine Assembly OEM Diagnostic Guide
Use this OEM manual diagnostic guide to troubleshoot operational engine symptoms on your Caterpillar 75-ton mining excavator:
| Engine Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Hard cold starting & MEUI Injection Pressure Fault | MEUI unit injector solenoid wear or fuel supply pressure drop below OEM limit (<0.4 MPa). | Inspect fuel transfer pump & ECM signals, or replace with Tatan complete CAT C15 ACERT engine assembly. |
| 2. Severe power loss & dense black smoke under digging load | Twin turbocharger wastegate failure leading to low boost (<1.5 bar) or MEUI injector nozzle tip fouling. | Inspect series turbocharger boost pressure or swap to a Tatan factory pre-tested C15 engine assembly. |
| 3. High engine oil consumption & heavy crankcase blow-by | Scored 15.2L cylinder liners, stuck oil rings, or valve stem seal wear allowing engine oil into combustion chambers. | Install Tatan new C15 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 CAT C15 complete engine assembly. |
