What are feeler gauges and what are they used for?

Feeler gauges are strips or blades of hardened steel that are ground or rolled to an accurate thickness. They are usually supplied in sets with a number of blades. Each blade is marked with its thickness in millimetres. They can be used singly, or two or more blades can be used together to obtain the required thickness. Feeler gauges are used to measure small clearances, such as tappet clearances. With the correct clearance, the feeler gauge should slide between the two parts with a slight resistance.

Feeler gauges are strips or blades of hardened steel that are forged to an accurate thickness. They are usually supplied in sets with a number of blades. Each blade is marked with its thickness in millimetres. They can be used singly, or two or more blades can be used together to obtain the required thickness. Feeler gauges are used to measure larger clearances, such as brake pedal free travel and disc rotor runout.

Feeler gauges are strips or blades of hardened steel that are ground or rolled to an accurate thickness. They are usually supplied in sets with no number on the blades. Each blade has to be measured using a micrometer to determine its thickness. They can only be used singly to obtain the required thickness. Feeler gauges are used to measure small clearances, such as tappet clearances.

All Answers are correct.

 

 

What are outside calipers, and what is the correct way to use them?

All answers are correct.

When the calipers have been adjusted to size, they are held against a steel rule to read the measurement.

Calipers can also be used to compare the sizes of two parts.

Outside calipers are normally used to measure the diameter of a shaft.

The calipers should be adjusted to slip over the shaft with a slight resistance. They should not be forced because this would spring the legs and prevent an accurate reading.

 

 

Are the three steps to reading a metric micrometer listed correctly below?

Step 1 – From the sleeve, read the number of whole-millimetre divisions that are visible on the main scale above the datum line.

Step 2 – Add to this a half-millimetre division if one is visible on the main scale below the datum line.

Step 3 – From the thimble, note the division that coincides with the datum line and add this to the previous readings.

True    False

 

4. Feeler gauges may be used to accurately measure length.
   True    False

 

5. Inside and outside calipers are used in conjunction with a steel rule.
   True    False

 

6. Micrometers are used for measuring accurately.
   True    False

 

7. Types of micrometers do not include depth micrometers.
   True    False

 

8. When reading a micrometer, the datum line is read last.
   True    False

 

A scriber is a piece of round, hard steel about 3 mm in diameter with a long sharp point. It is used to draw lines or marks on the surface of the work.

True    False

 

Surfaces such as the face of a cylinder head are checked along their length and also diagonally using a straightedge.

True    False

 

If a surface is warped, a feeler gauge will slide under a straightedge without resistance. Different thicknesses of feeler gauges can be used to determine the amount by which the component is warped.

True    False

 

Plastigage is used in conjunction with a micrometer to achieve an accurate measurement.

True    False

 

Specifications for components are provided in service manuals.

True    False

 

A steel rule is the basic measuring instrument. When used on its edge, a steel rule can be used to check the flatness of a surface.

True    False
