Chapter 03 Testbank Student: ___________________________________________________________________________ 1. What does the term ‘unserviceable’ mean? A. Difficulty in servicing a car; a very low car may be unserviceable because the hoist arms will not fit under it. B. Parts that have been damaged or worn beyond their specified limit are classed as unserviceable. This means that they must be replaced. C. Upselling to the customer; half-worn brake pads can be called unserviceable to increase productivity. D. Unserviceable parts may be kept for used cars or someone wanting a cheap repair. 2. Give two other names for the term ‘diagnosis’. A. ‘Fault finding’ and ‘the repair order’ are also referred to as diagnosis. B. Diagnosis is sometimes also referred to as ‘troubleshooting’ or ‘fault finding’. C. ‘Customer complaint’ and ‘fault finding’ can be used instead of diagnosis. D. ‘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? A. The marking are there purely for identification purposes for use on production lines by vehicle manufacturers. B. 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. C. 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. D. 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. 4. Measurement of the amount of wear may determine the suitability of a part for further use. True False 5. Suitable dismantling sequences can be found on the under-bonnet label. True False 6. Components are often cleaned before disassembly in order to decrease chances of identity problems. True False 7. Wear limits determine whether the part can be used two more times. True False 8. Parts no longer able to be used are classed as unserviceable. True False 9. Some self-locking nuts have built-in features that prevent them from working loose. True False 10.
