Question 170General Subjects - 1st Asst/Chief

The correct answer is A) Line shaft bearing housings are typically split half pedestal type bearing housings. This is the correct answer because split half pedestal type bearing housings are the most common arrangement for line shaft bearings on marine vessels. This design allows for easy installation and removal of the shaft without having to completely disassemble the bearing housing. The split housing can be opened to slide the shaft in or out, making maintenance and inspection more convenient. The other options are incorrect because single-piece pedestal or flange type housings do not provide the same ease of access to the shaft, and split half flange type housings are less common for line shaft applications.
