Clevite MS-1732M Engine Crankshaft Main Bearing Set

The Clevite MS-1732M is a high-performance M-Series crankshaft main bearing set designed for extreme operating conditions where crankshaft deflection and edge loading are concerns. This specialized bearing features a nominal .006-inch thick babbitt lining on a hardened steel back, providing exceptional conformability for engines experiencing severe crankshaft deflections.

M-Series Design Features:

• Thin babbitt lining on hardened steel back delivers superior conformability
• Enlarged chamfers for improved crankshaft fillet clearance
• Enhanced oil holes and grooves on select applications for optimal lubrication
• Engineered specifically for high-deflection racing and performance engines
• Precision-manufactured to tight tolerances for reliable performance

Application Notes:

M-Series bearings are purpose-built for engines where severe crankshaft deflection causes edge loading that would quickly damage conventional bearings. The high conformability of the babbitt lining allows these bearings to accommodate shaft distortion better than standard tri-metal designs. These bearings are intended for racing and high-performance applications where operating conditions are extreme and bearing service life may be shortened.

Installation Recommendations:

Due to the demanding conditions these bearings are designed to handle, frequent inspections are recommended. Bearings should be replaced at the first signs of distress to prevent potential engine damage. Proper bearing clearances and oil pressure are critical for optimal performance and longevity.

This main bearing set represents Clevite's commitment to providing specialized bearing solutions for the most challenging engine applications, from professional racing to extreme street performance builds.
