ASSIGNMENT  2 Textbook  Assignment: “Power Train”   and  “Chassis  Systems,”   pages 2-7 through 3-24. Learning  Objective: Recognize the  principles  and  components of  automatic  and  auxiliary transmissions. 2-1. 2-2. 2-3. 2-4. The  fluid  torque  converter  is attached  to  the  engine  crankshaft and serves as the engine clutch. 1. True 2. False When the transmission selection lever is in the drive (D) position, what operation controls the shifting of the transmission from drive to low and back to drive ? 1. Engine  speed 2. Propeller  shaft  rotation  speed 3. Rear  axle  rotation  speed 4. Front  axle  rotation  speed When placing a transmission selector lever in the drive (D) position,  an  operator  should  take what action to avoid premature forward  movement  of  a  vehicle? 1. Place wheel chocks in front of the rear wheels 2. Engage  the  parking  brake 3. Maintain  pressure  on  the foot brake 4. Slowly  engage  the  selector lever What is the function of an auxiliary   transmission? 1. Replaces  the  main  transmission at  high  temperature  operations 2. Replaces  the  main  transmission during  fording  operations 3. Provides  more  gear  ratios 4. Provides  front  axle  power 2-5. 2-6. 2-7. 2-8. What  conditions  causes  a  sprag  unit to  engage  automatically? 1. The rear wheels slip and turn faster than the front wheels 2. The operator shifts to low gear 3. The front wheels slip and turn faster than the rear wheels 4. High--speed  operation What  component  of  the  power train is used to drive auxiliary accessories? 1. Final drive 2. Transfer  case 3. Planetary gearset 4. Power  takeoff Learning  Objective: Recognize the  principles  and  components of  propeller  shaft  assemblies. What  assembly  provides  a  path through  which  power  is  transmitted from the transmission to the drive axle? 1. Final drive 2. Propeller shaft 3. Differential 4. Dog  clutch  assembly What  component  sits  between  and supports  two  propeller  shafts  on vehicles  with  a  long  wheel  base? 1. The  center  support  bearing 2. The  auxiliary  support transmission 3. The propeller support casing 4. The  universal  support  joint 9
