Victor MS685P10 Engine Crankshaft Main Bearing 0.010 Undersize

The Victor MS685P10 is an engine crankshaft main bearing (also called a crank bearing) for engine rebuilds. Main bearings support the crankshaft in the block and hold an oil film that separates the journal from the bearing surface. That film reduces friction and wear and helps the engine run smoothly.

Key Features:

• Size: 0.010" undersize, for crankshaft journals that have been machined undersize
• Bearing OD / block housing bore: 2.942"
• Thrust bearing flange width: 1.118"
• Construction: P-series design with cast copper-lead material, intended for heavy-duty, performance and older-engine rebuilds
• Specification: Made to meet or exceed OE specifications

Check journal diameter and bearing clearances with proper measuring tools before installation. Use the bearing size that matches your machined crankshaft.
