Certified Maintenance and Reliability Technician (CMRT) Practice Test

The correct choice is an arbor press because it is specifically designed to apply a controlled amount of force to a workpiece, allowing for precise and safe removal of components such as a shaft from a bearing. The arbor press provides the necessary mechanical advantage and stability, enabling the user to exert sufficient pressure without damaging the surrounding parts.

An impact wrench, while useful for loosening and tightening fasteners, does not offer the controlled force needed for the delicate task of pushing a shaft from a bearing. A ball peen hammer could potentially cause damage through excessive force or improper contact, and it lacks the precision offered by an arbor press. A hydraulic press is indeed effective for such tasks, but it may not be as practical in smaller or more confined spaces where an arbor press would be more suitable. Therefore, the arbor press is the recommended tool for this type of job.
