Description

The C3802072 (0.50 mm) Main Bearing Set is an OEM-grade oversize bearing set engineered for diesel engines that have undergone crankshaft machining or journal regrinding. When the crankshaft is machined undersize by 0.50 mm , these bearings restore correct oil clearance, maintain lubrication balance, and ensure stable crankshaft support under heavy-duty operation. Crafted from high-strength tri-metal alloy materials, this bearing set provides exceptional resistance to heat, fatigue, scoring, and metal-to-metal wear. Installing C3802072 0.50 mm oversize bearings helps eliminate common issues such as low oil pressure, bearing knock, vibration, and premature crankshaft wear. Perfect for professional rebuild shops, machine shops, and fleet maintenance operations, this bearing set delivers long-term reliability and OEM-level performance—making it a critical component for accurate diesel engine restoration. ✔ Key Features & Technical Advantages OEM-spec C3802072 0.50 mm oversize main bearing set Designed for crankshafts machined undersize by 0.50 mm Restores proper lubrication clearance and crankshaft alignment Reduces friction, heat buildup, and bearing wear under load Tri-metal bearing construction ensures maximum durability Prevents bearing knock, oil pressure loss, and crankshaft scoring Ideal for major overhauls, machining repairs & diesel engine rebuilds
