ASSIGNMENT 2Textbook Assignment:"Measuring and Repair Instruments" and "Internal Combustion Engines,"chapters 2 and 3, pages 2-1 through 3-23.2-1.To ensure accuracy when measuringcrankshaft end play, you shouldtake the measurement what minimumnumber of times?1.Five2.Two3.Three4.Four2-2.Which of the following proceduresis the correct method to followwhen opening a micrometer?1.Hold the frame with one handand turn the knurled sleevewith the other hand2.Twirl the frame3.Hold the knurled sleeve withboth hands and twirl the frame4.Twirl the knurled sleeve2-3.Which of the following statementsconcerning a bore gauge is NOTcorrect?1.It gives a direct measurement2.It is one of the most accuratetools for measuring a cylinderbore3.It checks the cylinder forout-of-roundness or taper4.It has two stationaryspring-loaded points and anadjustable point2-4.Why must you expose the boregauge, the master ring gauge, orother tools used to preset thebore gauge, and the part to bemeasured to the same environmentbefore measuring?1.Because it is a good practiceto have all the tools and thepart to be measured in oneplace2.Because a temperaturedifferential may cause yourreadings to be inaccurate3.Because by doinq so. you cancheck what else you needbefore starting a measurement4.Because by doing so, this willgive you some time to read thebore gauge operating manual2-5.A strain/deflection gauge is usedfor which of the followingmeasurements?1.Crankshaft run-out2.Crankshaft end play3.Both 1 and 2 above4.Crankshaft alignment2-6.When a strain/deflection gauge isused, readings are generally takenin how many crank positions?1.Six2.Five3.Three4.Four2-7.Once you have placed thedeflection gauge indicator inposition for the first reading.you do not touch the gauge untilall the required readings aretaken and recorded.1.True2.False9
