Description
Heavy-Duty Standard Crankshaft Main Bearings for Caterpillar 3013C Engines
Precision-engineered standard-size (STD) crankshaft main bearing set manufactured for Caterpillar 3013C (C1.5) industrial diesel engines. Designed to support the main crankshaft journals, reducing rotational friction and withstanding intense combustion loads and dynamic operating stresses.
Key Technical Features:
- Precision Standard Geometry (STD): Machined to exact factory specifications to maintain optimal crankshaft journal running clearances and oil pressure.
- Integrated Lubrication Profile: Features a continuous oil groove and precision-drilled oil feed hole to ensure constant hydrodynamic lubrication under all operating conditions.
- Multi-Layer Bearing Alloy: High fatigue strength, conformability, and embeddability protect the crankshaft against micro-particulate wear.
- Locating Tangs: Accurately placed locating lugs ensure positive retention and prevent rotational movement inside the engine block saddle.
Installation Advisory:
Ensure engine block bearing saddles and crankshaft journals are thoroughly cleaned and inspected for wear or scoring prior to assembly. Lubricate bearing surfaces with clean engine oil or assembly lubricant. Verify oil clearances with Plastigage according to factory workshop guidelines.
