  21. What drives the oil pump
    Front end of the crankshaft
  22. Before attempting to change the block bores what must be done
    Hone them
  23. When performing hone what percent must be cleaned
  24. When performing a block to bore clearance how many locations, how many measurements per location at what degree apart from each other
    • 6 different location

    • 90 degree apart
  25. If metal particles are on the cylinder how can they be removed
    Coarse flat stone
  26. Why must cylinder liners be honed
    • To break the glaze
    • Remove ridges
  27. Loose or improperly seated injector tubes may result in what
    • Compression leaks into cooking system
    • Result in loss of engine coolant
  28. Exhaust Valve, valve bridge and cam followers are lubricated how
    From overflow oil from the rocker arms
  29. When Removing the rocker arm shaft what do you not do and why
    • Force the rocker arms all the way back with the shaft in place
    • May impose load that will bend push rods
  30. A damaged rocker arm can cause what
    Side load and weaken push rod

    • Magnetic particle method
    • Fluorescent penetrant method
    • Non fluorescent penetrant method
    • Pressure test method
  32. Before can followers are installed what do you do
    Immerse them in clean cindol 1705 heated to 100-125 for at least 1hr
  33. Can you clean the push rods, springs and spring seats in clean fuel oil
    Yes the dry with compressed air
  34. How should the cam followers be cleaned and how should they not be cleaned
    • Lubricating oil or cindol 1705
    • Not with fuel oil
  35. Water and oil passages between the cylinder head and cylinder block are sealed how.
    Synthetic rubber deal rings

    On the lower bearing
  39. All crankshaft main bearing journals are drilled for an oil passage except
    Rear journal
  40. Can a cross head piston and a trunk piston be used together why or why not
    • No
    • because of weight difference
  41. The crosshead piston has how many pieces to it and what are they called
    • 2
    • Crown and the skirt
  42. The crosshead piston consist of how many different types of rings, what are they and how many of each one
    • 1 fire ring
    • 2 compression rings
    • 2 oil control rings
  43. On the crosshead piston what is the too firing ring known as
    Keystone ring
  44. Can you wire brush the piston skirt
  45. If compression rings are worn or stick what kind of effects will it have on the engine
    • Engine hard to start
