Which tool is used with an external bearing puller to remove bearings?

• A. Bearing puller
• B. Jaws
• C. Hydraulic extension
• D. Bearing separator

Answer: (D)

When removing bearings with an external puller, you need a bearing separator to provide a proper interface between the puller and the bearing. The separator sits against the bearing races and distributes the pulling force evenly, so the force is applied to the outer (or inner) race rather than directly to the delicate surfaces. This protects the races and shaft while allowing the bearing to be pulled off smoothly. The puller then grips the separator, which transmits the force to the bearing. Other options don’t fit because the separator, not the jaws alone or a hydraulic extension, is the accessory specifically designed to engage the bearing races and control load during removal.
