Description
Heavy-Duty Crankshaft Main Bearings – 0.25mm (0.010″) Undersize for Caterpillar 3013C Engines
Precision-engineered 0.25mm (0.010″) undersize crankshaft main bearing set manufactured for Caterpillar 3013C (C1.5) industrial diesel engines. Specifically designed for reground or reconditioned crankshaft main journals, restoring proper oil clearance, hydrodynamic lubrication, and structural stability under heavy service conditions.
Key Technical Features:
- Precision Undersize Specification: Calibrated strictly to 0.25mm (0.010″) undersize specifications to match professionally machined crankshaft journals.
- Integrated Lubrication Profile: Features a continuous oil groove and precision-drilled oil feed hole to guarantee uniform oil distribution across the journal face.
- Multi-Layer Bearing Alloy: Engineered tri-metal lining provides superior embeddability, extreme fatigue resistance, and protection against premature bearing wipe.
- Positive Locating Tangs: Accurately stamped tangs guarantee secure positioning within the cylinder block bearing saddle, preventing shell spin.
Installation & Machining Advisory:
This bearing set is intended strictly for crankshafts whose main journals have been precision-ground by 0.25mm (0.010″). Always measure journal diameters with a micrometer and verify assembled oil clearances with Plastigage prior to final torqueing. Lubricate all bearing shells thoroughly with clean engine assembly lube.
