The Crankshaft Main Bearing Driver is used to facilitate the accurate installation of crankshaft main bearings in engine assemblies. This tool ensures that the bearings are seated correctly and uniformly for the smooth operation and longevity of the engine. The driver provides a method for applying even pressure, preventing misalignment and damage to the bearings and the crankshaft during installation. It withstands the forces involved in bearing installation while maintaining accuracy.

Attributes:
• Bearings are easily removed by inserting a tool into the crankshaft lubrication hole and rotating the crankshaft clockwise to roll out.
• Roll in new bearings by rotating the crankshaft in a counterclockwise direction.
• Threaded hole in pin allows easy removal from oil passage if tool shears.

Applications:
The Crankshaft Main Bearing Driver is used in engine assembly and repair for the efficient installation of crankshaft main bearings, ensuring proper alignment and fit in engine blocks.
