Technician A says that a Simpson gearset is two planetary gearsets that share
a common sun gear. Technician B says that a Ravigneaux gearset has two
sun gears, two sets of planet gears, and a common ring gear. Who is
correct?
a.Technician A only
b.Technician B only
c.Both A and B
d.Neither A or B
Technician A says that a hunting gearset is one inwhich one drive pinion gear tooth contacts only certainring gear teeth. Technician B says that a partialnonhunting gearset is one in which one pinion toothcontacts only six ring gear teeth. Who is correct?a. Technician A onlyb. Technician B onlyc. Both A and Bd. Neither A nor B
Tech A says that if a noise is caused by a set of worn gears, it will normally be loudest in that gear while driving under a load. Tech B says that if the bearings on the input shaft, countershaft, or main shaft are worn, either front or rear, a growling noise will result when stopped in gear. Who is correct?
