- Technician A says that a gear tooth pattern identifies ring gear runout. Technician B says that gear patterns are not accurate if there is excessive ring gear runout. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardWhen servicing transfer cases, all of the following are correct, except_____. a. it must be supported on a transmission jack or safety stands b. the chain drive and a planetary gearset must be adjusted to specifications c. visual inspections for leaks and damage are necessary d. follow the manufacturers recommendations for lubricantsarrow_forwardTech 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?arrow_forward

It can be more pronounced on one of these than on the others.Drive noise is most pronounced when ________________, as the gear teeth are under load. The bearings are also under loadso that any lack of preload will allow the ________________ teeth to change their area of contact.Noise on overdrive occurs as the ________________ decelerates from medium speeds, while float ________________occurs under light cruising conditions.arrow_forwardA clicking noise during transrnission/transaxle operation may be an indication of ________. a. worn mainshaft (input shaft) bearings b. faulty synchronizer operation c. failed oil seals d. worn, broken, or chipped gear teetharrow_forward
