Which of the following specifications for engine timing gear train backlash would be typical?

What term is used to describe a gear that permits zero lash between intermeshing gears and also eliminates the risk of gears radially loading each other when at operating temperature?

When a cylinder valve is manufactured with a stem and head of different alloys, what is commonly used to join each part?

When variable valve timing (VVT) is used, what controls the VVT actuator?

Technician A says that a common cause of top end clatter in a diesel engine is loose set cylinder valves. Technician B says that loose set valves are subject to lower shock loads on opening and closing because they travel less distance. Who is correct?
