Glossary “anneal” Definition:
Heating and cooling of steel in the solid state, usually requiring gradual cooling.
a
annealing
Glossary “annealing” Definition:
A heat-treatment process to reduce hardness or brittleness, relieve stresses, improve machinability, facilitate cold working, or produce a desired microstructure or property in the metal.
annulus
Glossary “annulus” Definition:
Any type of ring gear, including the ring part of the ring and pinion in the differential, and the gears of the planetary gear set of an A/T.
angle mill
Glossary “angle mill” Definition:
A machining operation to mill the deck surface at a shallow angle on the exhaust side of the engine block in order to increase the compression ratio by decreasing the combustion chamber volume.
anchor pots
Glossary “anchor pots” Definition:
Small steel cups imbedded in the shop floor for anchoring vehicles when pulling out major damaged areas.
anchor rails
Glossary “anchor rails” Definition:
Steel beams in the floor for holding a vehicle secure while straightening.
anchoring equipment
Glossary “anchoring equipment” Definition:
It holds the vehicle stationary while pulling and measuring.
AND gate
Glossary “AND gate” Definition:
A digital logic gate that must have all of its inputs high to produce an output
aneroid bellows
Glossary “aneroid bellows” Definition:
An accordion-shaped temperature sensor charged with a small amount of volatile liquid. Temperature change causes the bellows to contract or expand, which, in turn, opens or closes a switch, such as a thermostat.
angle measurement
Glossary “angle measurement” Definition:
Divides a circle into 360 or more parts called degrees.
analog voltmeter
Glossary “analog voltmeter” Definition:
Voltmeter that indicates a reading by needle position.
anaroid tube
Glossary “anaroid tube” Definition:
A thermo-mechanical device in a fuel-injection system that regulates the amount of fuel being injected according to differences in temperature and pressure in the intake manifold.
anchor
Glossary “anchor” Definition:
A mounting point on a vehicle structure for a stressed, non-structural component, such as a seat belt or a seat.
anchor clamps
Glossary “anchor clamps” Definition:
Device bolted to specific points on the vehicle to allow the attachment of anchor chains. They distribute pulling force to prevent metal tearing.
anchor end
Glossary “anchor end” Definition:
That end of a brake shoe that is attached to a fixed point (anchor pin) on the backing plate.
anchor pin
Glossary “anchor pin” Definition:
Steel pin rigidly attached to the backing plate of drum brakes. Return springs are attached to the anchor pin and to the brake shoes to hold the shoes against the anchor pin in a non-applied position. In an applied position, it prevents the shoes from rotating with the drums.
analog instrument
Glossary “analog instrument” Definition:
An instrument having a needle on a dial used for taking measurements, such as temperature and engine RPM.
analog signal
Glossary “analog signal” Definition:
Electrical signal that varies in amplitude within a given parameter.
analog-to-digital converter
Glossary “analog-to-digital converter” Definition:
Electrical device used to convert analog signals to a digital code that represents the amplitude of the original signal.
anaerobic sealer
Glossary “anaerobic sealer” Definition:
Liquid or gel that bonds two parts together in the absence of air.
