Question 91General Subjects - QMED

The correct answer is D) An arbor press. Tapered roller bearings are delicate components that require specialized tools for proper removal and installation. Using an arbor press allows for the controlled and even removal of the bearing from the shaft, without risking damage to the bearing or the surrounding components. The tapered design of the bearing makes it susceptible to damage if struck directly with a hammer or other impact tool, which is why options A, B, and C are incorrect. Regulations and best practices for bearing maintenance on Coast Guard-inspected vessels require the use of an arbor press or other suitable hydraulic or mechanical press to safely remove tapered roller bearings without causing harm.
