Chapter 05 Testbank Key

1. (p.  ) How is the deck of the block checked for flatness?

The top of the cylinder block can be checked for flatness by using a straightedge and feeler gauge.

Difficulty: Easy
Section: Servicing cylinder blocks

2. (p.  ) How are cylinder bores measured?

Cylinders are measured in the following way:
1 – Before measuring cylinder wear, wipe the cylinder clean and examine it for scores and visible wear.
2 – Place the cylinder-bore gauge across the cylinder, just below the unworn ring ridge.
3 – Turn the bezel to set the dial gauge to zero.
4 – Move the gauge slowly up and down the cylinder to measure taper. The pointer will move on the scale.
5 – Turn the cylinder-bore gauge 90° in the cylinder to measure out-of-round.

3. (p.  ) What is Plastigage and what is it used for?

Plastigage is a soft thin plastic strip used to check a bearing oil clearance. The procedure is:
1 – Wipe the journal and bearing clean of oil.
2 – Place a strip of Plastigage in the centre of the bearing.
3 – Replace and tighten the bearing cap – do not turn the crankshaft.
4 – Remove the cap and, with the scale provided, measure the flattened Plastigage at its widest point – this is the bearing clearance.
