General Shop Equipment

Chapter 9


Objectives• Identify shop equipment• Understand the proper uses of equipment• Use equipment safely


Shop Equipment• Tools of the trade classifications

– Hand tools

– Portable power tools

– Equipment

• Major pieces of equipment shared among all employees are owned by the employer– Well-equipped shop will have most required

equipment


Hydraulic Equipment• Increases pressure

– Small piston moves a larger one

• Hydraulic jacks – Have a fluid reservoir and two one-way check

valves

– Twisting the handle controls fluid pressure

• Jackstand– Transfer load from the floor jack to the jackstand

• Creepers – Allow the technician to work under a car


Hydraulic Equipment (cont'd.)• Presses: mechanical or hydraulic

– Ten-ton electric/hydraulic press is for pressing wrist pins in and out of connecting rods

• Shop crane (i.e., cherry picker): removes engine– Engine sling hooks the shop crane to the engine

• Chain hoist: removes the engine– Engine stand is used for turning the engine over

for disassembly and reassembly

• Transmission jack: removes transmissions


Shop Electric Machinery• Electric machinery

– Includes anything with a motor

• Drill press– Drills parts clamped to press table

– Cutting lubricant is used on all metals except cast iron or aluminum

• Drill motors– Classified by largest drill bit its chuck can

accommodate


Heavy-Duty Power Tool Considerations

• Power tools designed for professional use are different than those designed for home use– Bearings on a drill motor: located at the front and

rear of the motor armature• Types: ball, roller, and powdered metal sleeves

– Drill chuck: made of case-hardened steel

– Housing: usually Super Tough™ nylon

– Power cord: usually eight to ten feet


Heavy-Duty Power Tool Considerations (cont'd.)

• Battery-operated tools– May have a adjustable clutch

– Fully discharged batteries accept a charge more fully

• Grinder– Typically has a wheel on one side and a wire

brush on the other• Grinder sharpens tools• Metal being ground must be quenched


Other Electric Equipment• Battery chargers

– Charge batteries and help start engines

– Some recommend against using the unit for starting the car

• Soldering tools– Include soldering iron, gun, and pencil

– Melt solder to join electrical wires


Other Shop Equipment• Bench vise

– Every shop has a vise

– Jaws usually have teeth

– Brass jaw caps prevent vise from marring workpiece

• Engine analyzer – Diagnoses engine problems (e.g., compression,

cylinder balance, worn timing chains, etc.)

• Tire changer – Uses air to unseat tire bead from the wheel rim


Welding Equipment• Arc welding

– Inexpensive and fast, but requires 220-volts

– Electric arc melts metal when electrons flow across the arc

• MIG welding– An inert gas shield is applied around arc area to

prevent oxidation of the metal

• Oxyacetylene welding– Oxygen and acetylene are mixed and ignited

– Intense heat melts steel for welding or cutting
