Description
Heavy-Duty Crankshaft Main Bearings – 0.50mm (0.020″) Undersize for Caterpillar 3013C Engines
Precision-engineered 0.50mm (0.020″) undersize crankshaft main bearing set manufactured for Caterpillar 3013C (C1.5) industrial diesel engines. Specifically engineered for crankshafts with main journals machined to a second-stage undersize, restoring factory oil clearances, hydrodynamic film stability, and load capacity.
Key Technical Features:
- Precision Second-Stage Undersize: Calibrated strictly to 0.50mm (0.020″) undersize dimensions for reground crankshaft main journals.
- Integrated Lubrication Profile: Precision oil groove and feed hole ensure an uninterrupted supply of pressurized lubrication to the rotating journal.
- Heavy-Duty Tri-Metal Composition: Provides exceptional fatigue resistance, conformability, and journal protection against debris embedment under severe engine loads.
- Positive Anti-Spin Tangs: Accurately located lugs fit securely into the block saddle and cap to prevent bearing displacement.
Installation & Machining Advisory:
This bearing set is intended strictly for crankshaft main journals ground to 0.50mm (0.020″) undersize. Verify journal diameters with an outside micrometer and confirm assembled oil clearances with Plastigage before final torque application. Always coat bearing surfaces with high-quality assembly lube prior to engine reassembly.
