Textbook 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 measuring
crankshaft end play, you should
take the measurement what minimum
number of times?
1.
Five
2.
Two
3.
Three
4.
Four
2-2.
Which of the following procedures
is the correct method to follow
when opening a micrometer?
1.
Hold the frame with one hand
and turn the knurled sleeve
with the other hand
2.
Twirl the frame
3.
Hold the knurled sleeve with
both hands and twirl the frame
4.
Twirl the knurled sleeve
2-3.
Which of the following statements
concerning a bore gauge is NOT
correct?
1.
It gives a direct measurement
2.
It is one of the most accurate
tools for measuring a cylinder
bore
3.
It checks the cylinder for
out-of-roundness or taper
4.
It has two stationary
spring-loaded points and an
adjustable point
2-4.
Why must you expose the bore
gauge, the master ring gauge, or
other tools used to preset the
bore gauge, and the part to be
measured to the same environment
before measuring?
1.
Because it is a good practice
to have all the tools and the
part to be measured in one
place
2.
Because a temperature
differential may cause your
readings to be inaccurate
3.
Because by doinq so. you can
check what else you need
before starting a measurement
4.
Because by doing so, this will
give you some time to read the
bore gauge operating manual
2-5.
A strain/deflection gauge is used
for which of the following
measurements?
1.
Crankshaft run-out
2.
Crankshaft end play
3.
Both 1 and 2 above
4.
Crankshaft alignment
2-6.
When a strain/deflection gauge is
used, readings are generally taken
in how many crank positions?
1.
Six
2.
Five
3.
Three
4.
Four
2-7.
Once you have placed the
deflection gauge indicator in
position for the first reading.
you do not touch the gauge until
all the required readings are
taken and recorded.
1.
True
2.
False
