Chapter 12, Problem 2ASRQ
While inspecting the timing gears of an engine: Technician A says a gear with cracks, spalling, or excessive wear on the tooth surface indicates improper gear backlash. Technician B says the diameter of many of the engines timing gears and sprockets should be measured with the drive chain wrapped around the individual gears. Who is correct?
- Technician A
