5801693305 OIL PUMP

IVECO OIL PUMP

🔧 What is the oil pump?

The oil pump is responsible for pumping lubricating oil from the oil pan throughout the engine so that it can:

• Lubricate moving parts (crankshaft, camshafts, pistons...).

• Dissipate some of the heat generated by combustion and friction.

• Help maintain constant oil pressure throughout the system.

⚙️ How does it work?

1. When the engine starts, the pump is driven by:

   • The crankshaft (directly or through gears).

   • In some cases, by an auxiliary chain or belt.

2. It draws oil from the oil pan through a pickup tube with a strainer (which prevents large contaminants from entering).

3. The oil passes through the pump and is pressurized.

4. It is sent through internal passages to:

   • The crankshaft main bearings and journals.

   • The camshaft and rocker arms.

   • The pistons and turbocharger (if applicable).

5. The system includes:

   • Pressure relief valve to prevent overpressure.

   • Oil filter to remove contaminants.

🧰 Types of oil pumps in IVECO engines

---

📍 Location

• Usually in the lower part of the engine, inside the oil pan or in the front cover.

• Driven directly by the crankshaft or the primary gear.

---

📈 Typical operating pressure

Values vary by engine (e.g., F1C, Cursor 8, NEF, etc.)

---

🚨 Symptoms of oil pump failure

• Oil pressure warning light illuminated on the dashboard.

• Metallic knocking from the engine (bearings not lubricated).

• Rise in oil temperature.

• Accelerated wear of the engine.

• In severe cases: engine seizure.

🛠️ Basic diagnosis

1. Using an external pressure gauge: connect it where the oil pressure sensor is installed.

2. Using diagnostic equipment (if supported by the engine): read the actual pressure values.

3. Check the pressure relief valve, pressure sensor, filter, and oil condition (the pump is not always to blame).

🧠 Key tips

• Always use the oil type and viscosity recommended by IVECO.

• Change the oil and filter at the specified intervals.

• Check for internal leaks (worn bearings → pressure loss).

• When rebuilding an engine or repairing the cylinder head → always check the condition of the pump.
