Textbook Question
Chapter 40, Problem 10ASRQ
While reviewing the procedure for setting backlash: Technician A says that backlash is adjusted along with side-bearing preload by loosening or tightening side-bearing adjusting nuts. Technician B says that normally, to decrease the amount of backlash, a thin shim is installed on one side of the gear and a thick one on the other side. Who is correct?
a Technician A only
b. Technician B only
c. Both A and B
d. Neither A nor B
