Description

This main bearing set (0.50 mm oversize) is a precision-engineered replacement designed for heavy-duty diesel engines using OEM part numbers 3802132 and 3802071 . Oversize main bearings are required when the crankshaft journals have been machined, restoring proper oil clearance and crankshaft alignment during engine rebuilds. Manufactured from high-strength tri-metal bearing alloys , this 0.50 mm oversize main bearing set is built to handle extreme crankshaft loads, high operating temperatures, and continuous diesel duty cycles. Correct main bearing fitment helps maintain stable oil pressure, reduce friction, and prevent premature crankshaft or block damage. This complete 0.50 mm main bearing set is ideal for bottom-end rebuilds, full engine overhauls, and professional diesel repair work where precision and reliability are critical. Each bearing shell is finished to OEM tolerances to ensure smooth rotation and consistent lubrication. Key Benefits: 0.50 mm oversize main bearing set OEM replacement for 3802132 / 3802071 Designed for machined crankshaft journals Restores proper oil clearance and pressure Reduces friction and bearing wear Suitable for heavy-duty diesel engine rebuilds
