What is the proper tool to drive a tapered bearing?

The proper tool to drive a tapered bearing is a spanner wrench. This tool is specifically designed to grip and turn components that have notches or holes, which is essential for handling tapered bearings accurately. Tapered bearings are often installed with a careful application of force to ensure they are seated properly and aligned correctly. A spanner wrench allows for this controlled and precise tightening without damaging the bearing or other components.

Using tools like a hammer or chisel could lead to improper seating and potential damage to the bearing, while channel-lock pliers do not provide the necessary grip and precision needed for this specific application. A dead-blow hammer might seem suitable for certain types of installation, but for the delicate process of installing tapered bearings, a spanner wrench is the most effective choice.
