Course Code and Name: AUR30620 Certificate III in Light Vehicle Mechanical Technology Unit Code: AURLTX103 Unit Title: Diagnose and repair light vehicle clutch systems For this assessment you are required to answer all of the questions. You are permitted to research the answers by reading the learner guide, text books, theory notes and accessing the internet. If more room is needed label each task with the question number and use headings or dot points to make your work clear for your trainer and assessor. Please follow the Referencing Guide contained on your Course handbook. Please attach a student assessment cover sheet to each unit submission. You must complete the cover sheet in full detail. 1. Identify five (5) important items of personal safety when working on manual transmissions in an automotive workplace. 1.Safety for head- Wearing a helmet offers protection and can prevent head injuries. 2. eye protection – safety glasses. 3. Hearing protection 4. protection for the feet- use safety shoes. 5. protection of hands- use gloves. 2. List three (3) precautions when jacking a vehicle on the floor. 1. Jack stands should be used when working underneath your car. Unsecured vehicles have collided with individuals and killed them. 2. Always stop an automobile from rolling by blocking the wheels before jacking it up. Use bricks, wooden wedges, or metal wheel clocks to block the wheel at the end of the car that isn't being raised. 3. Always park a car on a level surface before jacking it up. if you can't coast down the slope with a flat tyre without doing irreparable damage to it. Park close to the curb, turn the wheel toward the curb, then securely block the downhill wheel to stop the car from rolling. 3. Why should safety stands be placed under a raised vehicle? As safety stands don't lock, which ultimately leads to failure, they are employed to prevent damage from being caused by the jack's failure. Additionally, rather than holding the thing, the hydraulic mechanisms are used to elevate it. 4. What precautions should be observed if a vehicle is to be raised on a hoist? 1. Never exceed your vehicle lift's maximum capacity /var/filecabinet/temp/converter_assets/e1/c1/e1c1ce031653b657f5d4b2c1462150c436cadc4c.docx Imagine Education Assessment Questions Part A

2.Position vehicle with the centre of gravity cantered over lift frame of hoist. 3. Don't rely on a single lift arm to bear all the vehicle's weight 4.Read the owner's manual before you begin. . . 5. When using lifting equipment, what does SWL stand for? Select the correct answer. A. Safe weight lift. B. Safe working load. C. Safe working limit. D. Secure working load Answer= safe working load 6. Complete the following statement about safely removing a RWD transmission using the following words: o assembly o engine o lower o secure o slowly o transmission o vehicle o loosen Place a transmission jack under the transmission and _secure______ the transmission to it. Then loosen and remove the lower bell housing-to-engine block bolts and the cross member at the ___transmission___. After the mount is free from the transmission, _lower_____ the transmission slightly so you can easily access the top transmission-to-engine bolts. _loosen_____ and remove the remaining transmission-to-engine bolts. _slowly_____ and carefully move the transmission away from the __engine____ until the input shaft is out of the clutch assembly. Then slowly lower the transmission. Once the transmission is out of the _vehicle_____, carefully move it to the work area and mount it to a stand or bench. On some cars, the engine and transmission must be removed as a unit. The _assembly_____ is lifted with an engine hoist or lowered underneath the car. 7. Most often the engine and powertrain in a FWD vehicle is removed through the bottom of the vehicle. Special tools may be required to hold the transaxle and/or engine in place as it is being disconnected from the vehicle. True or False? True. 8. What three (3) practical methods of reducing the spread of asbestos should be followed in the workplace? /var/filecabinet/temp/converter_assets/e1/c1/e1c1ce031653b657f5d4b2c1462150c436cadc4c.docx

a) The first technique involves using the right disposal techniques for materials containing asbestos. b) The engineering controls method is the second technique. c) The second technique entails maintaining personal hygiene through the use, upkeep, and disposal of protective gear and garments that have been exposed to asbestos. It also stipulates that no food or beverages should be consumed close to regions that have been exposed to asbestos. 9. When handling, trapping, storing and disposing of new or waste hydraulic fluid, which document should you use to find this information? Safety data sheets. 10. How should waste hydraulic fluid be stored and disposed? Hydraulic fluid should be stored in a clear labelled shelf and disposed by a license contractor. 11. When changing the hydraulic fluid, what should you use to catch the waste fluid? Select the correct answer. A. Hydraulic bleeder B. Mop bucket C. Storm water drain D. Funnel Answer = funnel 12. What are two (2) main aspects to dealing with asbestos in motor vehicle repairs? Absestos must be handled and trapped safely. lowering the health risks posed by asbestos and safely managing component disposal. 13. All hydraulic fluids are hygroscopic – that is, they readily absorb water. True or False? True. 14. Use the appropriate cleaning liquid and equipment before and during disassembling a clutch assembly. Some clutch discs were made with asbestos. Inhalation of asbestos can cause serious illnesses. Assume that all clutch discs have asbestos and follow the procedures for containing it. True or False? True. 15. Complete the following statement about the basic principle of clutch operation using the following words: o clutch o disc o disengaged o drive o engine o flywheel o member o pressure /var/filecabinet/temp/converter_assets/e1/c1/e1c1ce031653b657f5d4b2c1462150c436cadc4c.docx

The pressure plate and _flywheel_____ are the drive or input members of the assembly. The __clutch____ disc, also called the friction disc, is the driven or output _member_____ and is connected to the transmission’s input shaft. As long as the clutch is _disengaged_____ (clutch pedal depressed), the drive members turn independently of the driven member, and the _engine_____ is disconnected from the transmission. However, when the clutch is engaged (clutch pedal released), the _pressure_____ plate moves toward the flywheel and the clutch __disc____ is squeezed between the two revolving __drive____ members and forced to turn at the same speed. 16. What is the coefficient of friction? A coefficient of friction is a measurement that illustrates the connection between the force of friction between two objects and their usual interaction. When alternative techniques are not available, it is a value that is occasionally used in physics to determine an object's normal force or frictional force. 17. When the clutch is firmly clamped between the flywheel and pressure plate, engine torque moves into the transmission. True or False? True. 18. A clutch assembly is designed to prevent any loss of torque when it is engaged, but it needs to allow some slippage as the disc begins to be squeezed between the pressure plate and the flywheel. This slippage prevents jarring that can result from the sudden transfer of power to the wheels. True or False? True. 19. The clutch allows the engine to idle while the vehicle is stopped. True or False? True. 20. The clutch is needed for gear shifting. True or False? True. 21. Name the major components of the clutch assembly below. /var/filecabinet/temp/converter_assets/e1/c1/e1c1ce031653b657f5d4b2c1462150c436cadc4c.docx

1. Clutch housing 2. Clutch fork ball stud 3. Clutch fork 4. Clutch lever 5. Pressure plate assembly 6. Flywheel 7. Clutch disc 8. Release bearing and hub 22. The clutch friction disc always rotates with the _______. Select the correct answer. A. Engine crankshaft B. Flywheel C. Pressure plate D. Transmission input shaft Answer = transmission input shaft 23. When the clutch is disengaged, the power flow stops at the ______. Select the correct answer. A. Transmission input shaft B. Driven disc hub C. Pressure plate and flywheel D. Torsion springs Answer = pressure plate and flywheel 24. The surface of the pressure plate contacts the ______. Select the correct answer. A. Transmission main shaft B. Throwout bearing C. Clutch disc D. Flywheel Answer= clutch disc 25. Coil spring-type pressure plates require less pedal effort than diaphragm-type pressure plates. True or False? /var/filecabinet/temp/converter_assets/e1/c1/e1c1ce031653b657f5d4b2c1462150c436cadc4c.docx
