Question

1. which of the following best describes the role of the auxiliary section in a truck standard transmission?

a. reduction of torque output
b. multiplies the number of available gear ratios
c. reduces transmission length
d. enables faster road speeds in lower ranges

1. to rotate a countershaft transmission - driven gear in the same direction of rotation as the drive gear, which of the following is a requirement?

a. the drive gear must be larger in diameter than the driven gear.
b. there must be two gears, and both must have external teeth.
c. there must be an idler gear between the drive and driven gears.
d. two gears must be in mesh, with one of them driving the other.

1. when a fuller roadranger low - inertia 13 - speed transmission auxiliary section is in high range, low split, in what position are the range and the splitter sliding clutches?

a. range sliding clutch forward, splitter sliding clutch rearward
b. range sliding clutch rearward, splitter sliding clutch forward
c. both sliding clutches forward
d. both sliding clutches rearward

1. when a constant - mesh transmission is in neutral, which of the following statements about the transmissions mainshaft gears is correct?

a. they are splined to the main or output shaft.
b. they are keyed to the main or output shaft.
c. they are free to turn on the main or output shaft.
d. they are keyed to the synchronizer hub.

1. when synchronizers are used in a transmission, the power flow is connected to the output shaft by the:

a. countershaft.
b. input shaft.
c. synchronizer sliding collar or clutch and hub.
d. synchronizer blocker ring.

1. what prevents transmission from being put in two gears at the same time?

a. shift rail detent balls and pins
b. shift rail interlock system
c. narrow shift gates
d. a larger shift finger

1. when a sliding gear is used in a transmission, it is connected to the mainshaft by:

a. splines in the sliding gear.
b. a sliding clutch.
c. a synchronizer.
d. a shift fork.

Explanation:

1. The auxiliary section in a truck transmission multiplies the number of available gear ratios.
2. An idler gear between the drive and driven gears is required to make the countershaft transmission - driven gear rotate in the same direction as the drive gear.
3. When the Fuller Roadranger low - inertia 13 - speed transmission auxiliary section is in High range, Low split, the range sliding clutch is rearward and the splitter sliding clutch is forward.
4. In a constant - mesh transmission in neutral, the mainshaft gears are free to turn on the main or output shaft.
5. When synchronizers are used in a transmission, the power flow is connected to the output shaft by the synchronizer sliding collar or clutch and hub.
6. The shift rail interlock system prevents the transmission from being put in two gears at the same time.
7. A sliding gear in a transmission is connected to the mainshaft by splines in the sliding gear.

Answer:

1. b. Multiplies the number of available gear ratios
2. c. There must be an idler gear between the drive and driven gears.
3. b. Range sliding clutch rearward, splitter sliding clutch forward
4. c. They are free to turn on the main or output shaft.
5. c. synchronizer sliding collar or clutch and hub
6. b. Shift rail interlock system
7. a. splines in the sliding gear
