Which tool is used to remove gears and bearings from a shaft without damaging the parts?

• A. Gear Puller
• B. Hammer
• C. Chisel
• D. Prying Bar

Answer: (A)

The idea is to remove gears or bearings from a shaft without causing damage, and the gear puller is designed for that job. It grips the part—behind the gear or on the inner race of a bearing—and uses a central screw or hydraulic force to pull everything straight off the shaft. This creates a controlled, even axial force that slides the component off without hammering, prying, or misaligning the bore. Using a hammer can strike surfaces and edges, risking chipped gear teeth, bent shafts, or misplaced bearings. A chisel or prying bar can gouge, nick, or distort surfaces, and a prying bar can slip or slip the workpiece, causing damage or injury. The gear puller avoids these issues by applying gradual, centralized pulling force and distributing load across the part surfaces.
