Micrometer

Answer A is wrong. Answer D is correct.

Answer B is wrong. Answer D is correct.

Answer C is wrong. The micrometer above is inch-based.

47. After removing a rear brake drum from a light truck with a solid rear axle, the technician notices the backing plate and brake shoes are wet with fluid. Technician A says a leaking wheel cylinder could be causing this contamination. Technician B says a leaking axle seal could be the cause. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

47.

Answer A is wrong. Both technicians are correct.

Answer B is wrong. Both technicians are correct.

Answer C is correct. Axle seals keep lubrication in while keeping water and debris out. They fail and leak from wear or damage. The rubber lip shrinks and hardens, and the garter spring gets weak, allowing differential fluid to bypass the seal, dripping onto the backing plate, and contaminating the brake shoes.

Answer D is wrong. Both technicians are correct.

48. Technician A says to use a dial indicator to check for flywheel runout. Technician B says to use a dial indicator to check for crankshaft endplay. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

48.

Answer A is wrong. Both technicians are correct.

Answer B is wrong. Both Technicians are correct.

Answer C is correct. To check the lateral runout on a conventional flywheel, place the tip of the dial indicator on the flywheel's surface, and then rotate the flywheel. The difference between the flywheels lowest and highest reading is the lateral runout.

Answer D is wrong. Both Technicians are correct.

Automotive part.

49. The part illustrated above contains:

  • A. A sealed wheel bearing.
  • B. A hub.
  • C. An ABS tone ring.
  • D. All of the above.

49.

Answer A is wrong. All of the above answers are correct. It's a picture of a hub and bearing with an ABS tone ring attached.

Answer B is wrong. The hub in the illustration has a sealed bearing installed.

Answer C is wrong. ABS systems use wheel speed sensor's to measure wheel speed with the passing teeth of the attached tone or reluctor ring.

Answer D is correct. They support the vehicle's weight as it accelerates, decelerates, and corners. Many have a wheel speed sensor or its companion tone ring incorporated into their design.

50. A squeal is heard from the clutch housing only when the clutch pedal is depressed completely to the floor. Technician A says this could be worn countershaft bearings. Technician B says the squeal is from a faulty pilot bearing. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

50.

Answer A is wrong. Countershaft bearings would make a noise whenever the transmission is operating.

Answer B is correct. A worn pilot bearing will make the most noise when the pedal is completely depressed, and the transmission's input shaft and the engine's crankshaft are rotating at different speeds.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
