Example Fault and Solution: CAT 320D Excavator

Fault: A CAT 320D (equipped with the C6.4 engine) experiences sudden, intermittent engine shutdown after operating for a short period. The diagnostic monitor shows a low fuel pressure code.

Diagnosis & Solution: This is a common issue often related to the fuel system's filtration.

1. Check Filters: The primary cause is typically a clogged fuel filter , such as the CAT 1R-0739 / 1R0739 or 1R-1804 . A blocked filter restricts fuel flow, causing the fuel pump to struggle and the pressure to drop, especially under load or as the fuel warms up.
2. Action: Immediately replace the fuel filter(s). Ensure genuine or high-quality aftermarket filters are used.
3. Check Fuel Shutoff Valve: If the filters are clean, inspect the CAT 298-3147 fuel shutoff valve / water separator for blockages or electronic failure that could intermittently starve the engine of fuel.
4. Preventative Action: Adhere strictly to scheduled maintenance intervals for fuel and oil filter replacement, especially when operating with lower-quality diesel fuel.
