Technician A says that the piston ring end gap should be measured in the cylinder bore and
compared to specifications. Technician B says that measuring piston-to-cylinder bore clearance
determines the compression ratio of the cylinder. Who is correct? - Correct AnswerTech A
Once you have done the engine assembly test buildup, and ensured that all the parts work fine,
which of the following do you NOT do before the final assembly? - Correct AnswerPerform a
test to check if the components are working properly.
Which of the following environments is NOT conducive to the engine assembly process? -
Correct AnswerA dirty environment
What is the main reason for performing a test buildup of an engine? - Correct AnswerTo
measure all of the critical clearances
Technician A says that after the crankshaft has been washed, be sure to take a small wire brush
and make sure all the oil passages are clean. Technician B says to flush the crankshaft oil
passages with hot oil. Who is correct? - Correct AnswerTechnician A
During the engine rebuilding process, all of the crankshaft journals should have been inspected
and ________ if necessary. - Correct AnswerReground
Technician A says that the wider the Plastigauge is squished out, the smaller the bearing
clearance. Technician B says that you should turn the crankshaft one full turn after the bearing
cap is torqued in place when using Plastigauge. Who is correct? - Correct AnswerTech A
After the main bearing inserts are installed, the ________ is installed, and then the clearance
between the crankshaft journals and the main bearings is measured. - Correct
AnswerCrankshaft
, Technician A says crankshaft end play is usually measured with Plastigauge. Technician B says
crankshaft end play can be measured with a dial indicator. Who is correct? - Correct
AnswerTechnician B
The ________ method gives an imprint of where the valve and piston have an interference issue
so that you will be better able to determine how to fly cut the pistons if necessary. - Correct
AnswerClay
Engine reassembly is being discussed. Technician A says that the engine should be painted to
protect it from rust and corrosion. Technician B says that the engine can be painted before or
after installing the oil gallery and any soft plugs. Who is correct? - Correct AnswerBoth
Technician A and Technician B
Technician A says that you should check piston to bore clearance with a dial indicator following
piston and rod installation. Technician B says check rod side clearance with a feeler gauge
following piston and rod installation. Who is correct? - Correct AnswerTech B
Two technicians are discussing the installation of various plugs into the heads and block.
Technician A says when installing gallery plugs and soft plugs, you should apply the appropriate
sealer to both. Technician B says always install any plugs clean and dry. Who is correct? - Correct
AnswerTech A
Technician A says carefully install piston rings with any marks facing the correct way. Technician
B says piston rings can be installed in any direction because they are not directional. Who is
correct? - Correct AnswerTechnician A
A liberal amount of bearing assembly lube should be placed on both halves of the ________
bearing inserts and the journal on the crankshaft. - Correct AnswerConnecting rod
