Vehicle manufacturers specify torque values for certain fasteners. This is to make sure that fasteners are not over- or under-tightened. The torque wrench is used to apply a specified amount of torque to a fastener. The torque angle gauge is used to make sure there is equal tightness of fasteners on a component. The objective of this procedure is to show you how to use a torque angle gauge in conjunction with a torque wrench.
Fasteners are used to secure components or pieces of components together. There are two main types of fasteners: inch and metric. They are not compatible. The objective of this procedure is to show you how to identify the common types, length, diameter, grade and thread pitch of threaded fasteners.
A vacuum gauge is used to measure the manifold pressure. In naturally aspirated engines, this pressure is always below atmospheric pressure. It is referred to as a vacuum. The objective of this procedure is to show you how to connect and use a vacuum gauge to check engine manifold vacuum.
Dial indicators are used in many types of service jobs. They are particularly useful in determining run-out on rotating shafts and rotors. Dial indicators can measure with an accuracy of 0.001" or 0.01mm. The objective of this procedure is to show you the correct method of measuring using a dial indicator.
Feeler gauges are strips of hardened metal that have been ground or rolled to a precise thickness. They can be very thin and will cut through skin if not handled correctly. The objective of this procedure is to show you the correct choice and use of feeler gauge sets.
Micrometers are available in metric and inch graduations. Typically, an inch micrometer has an accuracy of 0.001" and a metric micrometer has an accuracy of 0.01mm. The objective of this procedure is to show you how to measure using an outside micrometer.
There are two main types of tire pressure gauges: fixed workshop gauges and portable pocket size gauges. The objective of this procedure is to show you how to use a tire pressure gauge and interpret the readings correctly.
