Workshop Test Equipment

Tool/Equipment	Appropriate Use	Auto Specific?
Analyser (Scan Tool)	An electronic device for reading any stored diagnostic trouble codes in a vehicle. It will typically be able to show live data from the vehicle. It is connected to the vehicle using a data link connector.	Yes
Engine Analyser	An engine analyser is a complex, multi-function instrument that can help diagnose engine and engine-related problems or assist in tuning following an overhaul. An engine analyser can be used with petrol and diesel powered vehicles. Among the components and test capabilities it may include are pressure and vacuum gauges, a tachometer, a timing light, a voltmeter, ammeter, and ohmmeter, a vacuum pump, a cylinder output test, an exhaust/emissions analyser, and an oscilloscope.	Yes
Digital Multimeter	A generic multi-purpose electrical measuring device capable of measuring voltage, current, and resistance across of range of values. It can also be used for continuity testing of wires, for example, in the wiring harness of a vehicle. An essential tool when diagnosing electrical faults in a vehicle.	No
Timing Light	A stroboscope device used for setting the ignition timing of an engine equipped with a distributor. The light is used to illuminate the timing marks on the crankshaft with the engine running. This gives an indication of how much the distributor needs to be rotated to correct the timing.	No

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
