Question 1

What type of cleaners should NOT be used on aluminum components?

Answer 1

Caustic solutions

Question 2

In a cylinder block overhaul, what should be removed so coolant and oil passages can be thoroughly flushed?

Answer 2

Expansion and threaded plugs

Question 3

During cylinder block cleaning, what should NOT come in contact with high pressure steam or water?

Answer 3

Any part of your body/skin

Question 4

DYE CHECK is a method of crack detection that is used on what materials?

Answer 4

It can be used on all types of metals

Question 5

Before the components that have been tested using the magnetic particle/magnaflux method, it is necessary to:

Answer 5

Clean the components thoroughly to remove any test materials

Question 6

When pressure testing a cylinder block, it should be immersed in hot water to:

Answer 6

Allow expansion of the cylinder block

Question 7

The machined surfaces of the cylinder block should be checked for flatness using:

Answer 7

A straight edge and feeler gauge

Question 8

The most common fix for stripped threads in a cylinder block is:

Answer 8

Helicoils or (solid) threaded inserts

Question 9

Main bearing bores that are misaligned could cause:

Answer 9

Excessive bearing wear and a broken crankshaft

Question 10

Main bearing bores should be measured to determine what three issues?

Answer 10

1) Out of round
2) Max wear
3) Taper

Question 11

Machining the cylinder block deck surface to correct for warpage will:

Answer 11

Decrease the distance between the crankshaft centerline and the block deck

Question 12

Installing the main bearing caps backwards, or in the wrong position, on the cylinder block will cause:

Answer 12

Misalignment of the bearing bores

Question 13

The majority of the cylinder wear occurs at:

Answer 13

The top of ring travel, 90° to the crankshaft centerline

Question 14

During the inspection of a cylinder block, the measured taper of the cylinder bores is 0.009”. The correct oversized liner size would be:

Answer 14

0.020” - as you double the taper size and use the next largest oversize available

Question 15

When reconditioning a cylinder bore, a de-glazing hone can be used to:

Answer 15

Restore cylinder wall crosshatch

Question 16

After honing cylinder bores, they should be thoroughly cleaned using:

Answer 16

Hot water, soap, and a stiff bristle brush

Question 17

The two precautions that are necessary when using a screw type liner puller are:

Answer 17

1) the bottom is fastened correctly and will not hit the block upon removal
2) Do not position the assembly over holes/weak areas of the block surface

Question 18

To prevent distortion after removal from the cylinder block, liners should be stored:

Answer 18

Vertically

Question 19

Wet liner counterbores should be visually inspected for:

Answer 19

Cracks, erosion, and signs of coolant leakage

Question 20

Liner cavitation would be best described as:

Answer 20

Pitting on the outer surface of a wet liner

Question 21

What is the installed height for the following liner when:

• counterbore depth is - 0.439”
• liner flange thickness is - 0.441”
• shim thickness is - 0.003”

Answer 21

Installed height is 0.005”

Question 22

During the inspection of a cylinder block, all the counterbores have depth measurements that vary 0.004”. The correct service procedure would be to:

Answer 22

Machine the counterbores and use shims to restore liner height

Question 23

Dry liners which fit the block with too much clearance can be repaired by:

Answer 23

Boring or honing the block for oversized liners

Question 24

Seal rings on a wet liner that roll or twist during installation can cause:

Answer 24

Distortion of the liner bore

Question 25

Wet liner seal rings should be lubricated:

Answer 25

Just before liner installation
