Student: ___________________________________________________________________________

1.    

What does the term ‘unserviceable’ mean?

1.    

Difficulty in servicing a car; a very low car may be unserviceable because the hoist arms will not fit under it.

1.    

Parts that have been damaged or worn beyond their specified limit are classed as unserviceable. This means that they must be replaced.

1.    

Upselling to the customer; half-worn brake pads can be called unserviceable to increase productivity.

1.    

Unserviceable parts may be kept for used cars or someone wanting a cheap repair.

 

 

2.    

Give two other names for the term ‘diagnosis’.

1.    

‘Fault finding’ and ‘the repair order’ are also referred to as diagnosis.

1.    

Diagnosis is sometimes also referred to as ‘troubleshooting’ or ‘fault finding’.

1.    

‘Customer complaint’ and ‘fault finding’ can be used instead of diagnosis.

1.    

‘Fitment of parts’ and ‘servicing’ are two other names for diagnosis.

 

 

3.    

What do the numbers or lines embossed in the head of a bolt or fastener represent?

1.    

The marking are there purely for identification purposes for use on production lines by vehicle manufacturers.

1.    

They represent the pitch thread and bolt diameter for both metric and SAE bolts; larger-diameter bolts have a higher number and more lines on the bolt head.

1.    

These markings identify the metric tapping size appropriate for that bolt. The higher the number on the bolt head, the finer the pitch required for thread tapping.

1.    

These markings represent bolts of different classes and their strength. For bolts with numbers, the higher the number, the stronger the bolt. Some bolts with recessed heads have embossed lines: two lines represent class 5 and three lines represent class 7.
