2-8. 2-9. 2-10. 2-11. 2-12. What  is  the  most  preferred  ratio 2-13. Which of the following is NOT the of  the  torque  multiplier? result  of  an  improperly  cooled cylinder  liner? 1. 5 to 1 2. 2 to 1 3. 3 to 1 4. 4 to 1 1. Liner  failure 2. Thermal  stress 3. Uneven  heating 4. Fluctuation  in  rpm If you use an extension to a torque  adapter,  how  should  the torque applied to the part or fastener  compare  to  the  torque indicated  on  the  torque  wrench? 2-14. Which  of  the  following  conditions is NOT a cause for the liner to be improperly  seated? 1. It will be the same 2. It will be greater 3. It will be less 1. Metal  chips 2. Oversized  liner 3. Nicks  or  burrs 4. Improper  fillets Before  you  begin  an  inspection  or test of an engine frame or block, what should you do first? 2-15. Broken  piston  rings  will  cause which  of  the  following  problems? 1. Consult  the  manufacturer's manual  because  specific procedures  vary  with  different engines 2. Check  the  engine's  preventive maintenance   schedule 3. Clean the outside of the engine   thoroughly 4. Warm up the engine 1. Scored  cylinder  liners 2. Connecting  bearing  failure 3. High  lube  oil  temperature 4. High  freshwater  temperature 2-16. Which of the following symptoms is an indication of a scored cylinder? A dye penetrant test meets the requirements  for  quality  assurance when it is conducted by what person? 1. High  compression  pressure 2. Rapid  wearing  out  of  strainers and liner parts 3. Low  compression  pressure 4. Cracked  or  broken  piston  rings 1. A  QA  inspector 2. Any  qualified  person 3. A  certified  nondestructive testing  technician 4. A  well-trained  engineman 2-17. Which  of  the  following  conditions will  produce  out-of-round  cylinder liners? Which  of  the  following  conditions could indicate a crack in the cylinder liner of an engine? 1. Operating the engine at too low a temperature 2. Defective  main  bearing 3. Piston  side  thrust 4. Improperly  seated  head 2-18. How do you determine liner wear? 1. Water  standing  atop  the cylinder's  piston  after  the engine  is  secured 2. Abnormally  high  cooling temperature  when  the  engine  is operating 3. Large amount of water in the lubricating  oil 4. Each of the above 1. Take  piston  and  liner measurements  and  qet  the difference 2. Take  measurements  at  three levels in the liner 3. Compare wear of piston rings 4. Compare  compression  readings 10
