Ratchet and Sockets

Tool/Equipment	Appropriate Use	Auto Specific?
Ratchet	Can be used in combination with sockets to provide torque when tightening fastenings. The ratchet allows the handle to be returned to its original position without the need to remove the socket from the fastening. Torque is applied in one direction, and free movement applies in the other direction. A switch allows the direction in which torque is applied to be reversed, for tightening or loosening a fastening.	No
Standard Sockets	Attached to a fastener and then turned using some form of handle depending on the application. Available in various sizes and styles to fit different shaped fasteners.	No
Deep-well Sockets	Similar to standard sockets but with a deeper side allowing, for example, nuts to be tightened further onto a bolt or allowing access in confined spaces where standard sockets would not reach.	No
Plug Socket	A socket specifically used for spark plug removal and installation. It has enough depth for the top of the plug to fit inside, and its diameter fits a standard spark plug hex fitting.	Yes

Spanners

Tool/Equipment Image Appropriate Use Auto Specific? Torque Wrench Tightening nuts and bolts to a specific torque. In some situations, for example, attaching wheels, the fastenings need to be tightened to a specific torque so they are not too loose or become damaged by being over tightened. No Box Spanners General use of tightening nuts and bolts. Each end is a different size to reduce the total number of spanners required to cover a range of bolt sizes. The ends generally have 6 or 12 points to provide ease of use on hexagonal shape bolt heads. No Allen Spanners (Hex Keys) To drive in bolts or screws with hexagonal sockets. They have the advantage of providing 6 contact surfaces during use. No Ratchet Box Spanner Similar to a box spanner but more suitable in situations where rotational space is limited. The ratchet allows the spanner to be returned to its original position without the need for removing it from the fastening. Torque is applied in one direction, and free movement a...

Distributorless Ignition Systems

Investigation – Investigating Distributorless Ignition Systems Distributorless ignition systems (DIS) are used to ensure the air and fuel mixture in an engine is ignited at exactly the right time for efficient combustion to occur. They comprise mechanical and electrical components that, together, provide appropriate timing of the spark at each spark plug. Use the information in the related presentation to identify the components and voltage waveforms of DIS. Distributorless Ignition Systems a) Identify the components of this distributorless ignition system. A - ECU B - Crankshaft position sensor C - Ignition control module D - Coil pack E - Spark plug wires F - Spark plugs b) Draw a diagram to show the relationship between the primary voltage waveform and the secondary voltage waveform for one ignition coil. Ensure the diagram shows the waveforms for 2 spark plugs. A typical early DIS system will comprise which of these components? Select all the correct answers. Ignition control...

Miscellaneous Workshop Equipment

Miscellaneous Workshop Equipment Tool/Equipment Image Appropriate Use Auto Specific? On-vehicle Brake Lathe Used for skimming brake discs to remove imperfections or damage from brake pads. Saves removing the discs from the vehicle. Yes Bench Brake Lathe A lathe designed specifically for finishing brake drums and brake discs. Yes Parts Cleaning Tank Used for cleaning the inner and outer surfaces of parts prior to installation in a vehicle. Many parts may be reused on a vehicle if they are cleaned of dirt and debris. No Hydraulic Press The hydraulic press uses hydraulic pressure to apply a force to parts. They can be used in a forming process or for splitting components, for example, removing a bearing. Even a small press can produce several tonnes of force. The example shown produces 10 tonnes of force. No
