1 AST 105 2A 2 Power Point # 2 Hand Tools and Shop Equipment 5-1

2 Objectives List the common types of shop equipment and state their purpose. Describe the use of common pneumatic, electrical, and hydraulic power tools found in an automotive service department. 5-2

3 Hydraulic Tools Tools powered by pressurized liquid Typical hydraulic tools used in the automotive shop: jacks cranes presses 5-3

4 Floor Jack Used to raise either the front, sides, or rear of a vehicle Never leave jack handle down 5-4

5 Transmission Jack Designed to hold transmissions and transaxles during removal and installation May be similar to a floor jack (low) May use a long post that can reach high into the air for use when a car is on a lift 5-5

6 Transmission Jack This hydraulic stand can be extended to a height of 72 There are floor models available as well for servicing vehicles that are on jack stands 5-6

7 Portable crane/cherry picker Portable cranes are used to remove the engine from a vehicle A sling, either a chain or lift strap, is attached to the engine and hooked to the crane 5-7

8 Portable crane/cherry picker Many manufacturers use lift hooks during assembly at the factory and leave these hooks installed on the engines, these are usually the best location to install the sling. Consult service manual for specific lift locations if no hooks are found on the engine 5-8

9 Engine Stand Used to hold an engine once it is removed from the vehicle The engine bolts to the stand The engine can usually be rotated and held in different positions, making it easy to work on 5-9

11 Engine/transmission support Engine /trans support brackets must be installed if removing one, but not the other 5-11

12 Hydraulic Press Used to install or remove gears, pulleys, bearings, seals, and other parts requiring a high pushing force Always make sure components are seated securely in press Do not attempt to operate a hydraulic press without training and supervision 5-12

13 Hydraulic Press A hydraulic ram extends as the pump handle is worked The ram presses the parts against a table 5-13

14 More Shop Equipment There are various pieces of shop equipment that a technician may find useful These include: tire changers stands cleaners welders lights and creepers 5-14

19 Cold Solvent Tank Contains a pump, reservoir, and solvent used to remove grease and oil from parts 5-19

Steam Cleaner and High-Pressure Washer Used to remove heavy deposits of dirt, grease, and oil from the outside of large assemblies, such as engines, transmissions,

20 Steam Cleaner and High-Pressure Washer Used to remove heavy deposits of dirt, grease, and oil from the outside of large assemblies, such as engines, transmissions, and transaxles Wire brush the item to be cleaned and collect oil-soaked dirt before washing Dispose of the oil-soaked material properly Do not use near electronics 5-20

21 Steam Cleaner 5-21

22 Oxyacetylene Torch Used to cut, heat, weld, or braze metal parts Regulators Hoses Acetylene Tank Oxygen Tank Torch Body and Mixing Valves 5-22

23 Welder Uses high current to create an electric spark, or arc The arc is hot enough to melt and fuse metal parts together Be sure to complete proper training before attempting to weld 5-23

24 MIG Welder A MIG welder is a type of electric welder Uses an inert gas to prevent the molten steel from oxidizing 5-24

25 Soldering Gun (Iron) Used to join wires Electric current heats the tip of the gun The hot gun tip is used to heat the wires Solder is applied to the hot wires and it melts solder is a lead-tin alloy When the solder cools, it hardens into a strong, solid connection 5-25

26 Soldering Gun (Iron) A. Soldering iron A B B. Soldering gun 5-26

27 Battery Charger Used to recharge a dead car battery Forces current back into the battery to recharge the plates and battery acid The red charger lead connects to the positive (+) battery terminal The black charger lead connects to the negative (-) battery terminal Connect the leads before turning on the charger to avoid arcing 5-27

28 Battery Charger & Booster Booster Pack Battery Charger 5-28

29 Droplight Provides a portable source of light that can be taken to the repair area Beware of an electric shock hazard when working on a wet vehicle Use caution when using a droplight around fuel if you drop a light on the floor, a bursting bulb can ignite gasoline 5-29

30 Droplight 5-30
