Oil Pump
Volvo

The oil pump is the heart of the lubrication system, circulating engine oil under pressure to critical components and bearings. It uses a gear or rotor mechanism to move oil from the sump through filters and passages, ensuring effective lubrication at startup and during high‑load operation. A robust oil pump maintains consistent oil pressure, supports cooling through improved oil flow, and reduces wear on camshafts, pistons, and crank bearings. Worn or under‑performing pumps can lead to low oil pressure, accelerated wear, and reduced engine life, especially in heavy‑duty cycles with high horsepower and extended idling. Maintenance considerations include verifying drive belt integrity, clearances, and screen cleanliness to prevent debris ingress. Upgrading to a high‑quality pump can deliver more stable pressure and longer service life in demanding environments.
