Description

The 3802072 (0.50 mm) Main Bearing Set is a heavy-duty OEM-grade oversize bearing set engineered for diesel engines requiring crankshaft regrinding or machining. When a crankshaft is machined undersize by 0.50 mm , these bearings restore the correct oil clearance, ensure proper crankshaft alignment, and maintain stable lubrication flow. Constructed from high-strength tri-metal alloys, the 3802072 oversize bearings deliver outstanding resistance to heat, fatigue, scoring, and long-term wear—making them ideal for high-load commercial, industrial, and fleet diesel applications. Replacing worn bearings with this 0.50 mm oversize set prevents oil pressure loss, bearing knock, and crankshaft damage, ensuring reliable engine performance after machining repairs or a full overhaul. ✔ Key Features & Technical Advantages OEM-spec 3802072 0.50 mm oversize main bearing set Designed for crankshafts machined undersize by 0.50 mm Restores proper oil clearance and crankshaft support High-strength tri-metal construction for maximum durability Reduces friction, heat, bearing wear & crankshaft scoring Prevents low oil pressure, vibration & bearing failure Ideal for complete rebuilds, machining repairs & diesel overhaul projects
