Lexicon: Please help add to this

Please read through this, this is a working copy that will be updated with submissions. If theres anything you wish to add, any mistakes, or if you don't like the way something is worded, post it so we can add it. If there are any terms you have run across that have had you stumped, post them so we can answer it, chances are someone else is probably stumped too.

Descriptions should be kept simple. One paragraph should be enough, if you have more than that, you might consider starting a new thread and use it as a tech article.

This list is sorted by subject to make it easier to see whats been left out.

Newest entries are in Bold

========================

--Brakes--

Caliper - The part of a disk brake system that applies pressure to the brake pads, which in turn apply pressure to the brake rotors (disks).

Brake Drum - Houses the wheel cylinder, brake shoes, and several springs. Rotates with the tire and the brake shoes apply pressure to the inner surface of the drum when the brakes are applied.

Brake Fluid - The fluid used by the hydraulic brake system to apply pressure to the brakes. Available in several grades. See Tech Article "Brake Fluid DOT Grades" for more information.

Brake Master Cylinder - This is where the fluid is stored (in the fluid resevoir) and where the pedal forces the fluid through the brake lines, to apply pressure to brakes the themselves.

Brake Pad - The actual friction surface between the brake calipers and the rotors in a disk brake system. These wear down over time and must be replaced.

Brake Rotor - The rotor is the disk in a disk brake system. It rotates with the wheel, and pressure from the calipers is applied to this by the brake pads when the brakes are applied. (did that make sense?)

Brake Shoe - The actual friction surface between the wheel cylinder (hydraulic pistion) and the inner surface of the drum in a set of drum brakes. They serve the same purpose as brake pads, but don't wear out as quickly, and aren't as simple to replace.

DOT3 - Type/quality of brakefluid

--Chassis--

DEW98 - - Ford's latest mid-size, rear-drive chassis which is used for the new Ford Thunderbird, Lincoln LS and Jaguar S-Type and is suspected to be the base of the 2005 Mustang.

FN10 - - The Chassis desigantion for all '93 through '98 MarkVIIIs

FOX - - The Chassis designation for (years?) Mustangs, Thunderbirds, Cougars, and MarkVIIs

MN12 - Midsize North America Project #12 - The Chassis designation for all '89 through '97 Thunderbirds and Cougars

Panther - - The Chasis designation for (years?) Crown Vics/Grand Marquies (and TownCars?)

SN95 - - The Chassis designation for the '95 through '04 Mustangs

Lightning - Ford's sport truck with production runs from 93-95(?) and from 99-04(?). The first production run featured a 351 Windsor engine while the 99-04 version had a supercharged 5.4L SOHC engine.

MarkVIII - The Lincoln made cousin to the MN-12 Thunderbirds and Cougars. This car came standard with the DOHC 4.6L with output ratings of 280 HP @ 5500 PRM and 285 Ft-lb of torque at 4500 RPM for the base models and 290 HP @ 5500 RPM and 295 Ft-Lb of torque for the LSC models.

--Engines--

Mod Motor - Ford's Modular Motor - This is the name for the modular line of engines, including the 4.6(V8), 5.4(V8), and 6.8(V10) Liter engines. The modular comes from the fact that the same tooling, with only small changes, can be used to produce any these engines. The 5.4 is basically the 4.6 with a taller deck height and longer stroke, the cylinder heads between these engines can be interchanged. The 6.8 is basically the 5.4 block with an extra 2 cylinders in the middle. The heads for this engine resemble the 5.4 heads with provisions for the extra cylinder each.

Port Matched - When you match the size of ports that connect to each other. For example upper and lower intake. Usually done with an air-powered Die-Grinder, a Dremel does not have enough power.

Rich - Engine getting too much fuel compared to the air it's getting. Not neceserly a bad thing but not good either.

Retarded Timing -

Spark Knock -

Spark Retard -

Spark Timing -

Stroked - Using a Crankshaft that has a longer stroke than stock, this increases the distance the piston moves, increasing the cylinder volume. Larger cylinder volumes make more power up untill the point where the critical speed of the assembly (redline) is reached and something breaks.

Continued from above:

--Rear Differential--

7.5 gear - The diameter in inches of the ring gear found in V6 non-supercharged MN12s.

8.8 gear - The diameter in inches of the ring gear found in V8 and Supercharged MN12/FN10s. It is stronger than the 7.5 inch gear. It is also used in other Ford Vehicles, such as the Mustang, Panther platform cars and in some trucks.

Carrier - This contains the differential ("spider") gears and carries the ring gear of the ring/pinion set. All is contained within the differential housing or "pumpkin".

Constant Velocity Joint -

C.V. Joint -

Diff. - see Differential

Differential - Directs power to the wheels, can be either open(see Open Diff) or locking(see Trac-Loc)

Final Drive Ratio - see Gear Ratio

Gear Ratio - The ratio of the Ring and Pinion Gears in the rearend. Different Gear Ratios will cause the wheels to turn at different RPMs at any given driveshaft RPM Common Ford gear sizes are 2.73?, 3.08, 3.27, 3.55, 3.73, 4.10, and 4.30. There is a company producing a set of 3.90 gears, I believe it is Motive that is doing this.

Half-Shafts - Like Axles, except that these have (universal or Constant Velocity?) joints in them and are used in an Independant Suspension setup. They connect the Differential to the wheel hub and transfer power.

IRS -

Live Axle -

Open Differential - A non-locking differential. This will allow one wheel to turn while the other does nothing, resulting in a 'one wheel peel' and poor traction.

Open Rear - see Open Differential

Pinion Gear - A shaft with a small helical gear cut into one end, the other end bolts to the driveshaft flange

Ring and Pinion Gears - A set of gears designed to work together to transfer the power from the driveshaft to the rear wheels. The Pinion Gear is connected to the driveshaft, and has a small end with helical gear teeth, these engage the Ring Gear which is attached to the differential. Different Gear Ratios will cause the wheels to turn at different RPMs at any given driveshaft RPM

Ring Gear - Large round gear with teeth cut into one side, this gear attaches to the differential.

Trac-Lok - A locking differential. This will allow both wheels to get power and turn at the same rate when going straight, and still allow them to turn at different rates when the car turns a corner. This gives much better traction than an Open Differential. The locking action is accomplished by a spring and two sets of clutches, one set for left and one set for right, these clutches will engage or dissengage to keep both wheels turning the same, or allow one to slip.

Universal Joint -

--Sensors--

ACT - Air Charge Temperature sensor - Measures the temperature of the air comming into the engine, commonly used in super/turbocharged setups.

C&L MAF -

GT-MAF - MAF sensor off of a late model Mustang GT. Larger size than stock (available in 80mm and 85mm, stock is 70mm) with much more accurate air metering. Recommended for mild to wild normally aspirated engine combinations. A chip is required in order for the MAF to work properly. Requires a new engine harness pigtail on vehicles 1995 and older.

IAC - Idle Air Control - An opening that allows air to flow to the engine when the throttle blade is completely closed, hwen it gets clogged the engine will have a rough idle, or not idle at all.

IAT - Intake Air Temperature sensor - Measures the temperature of the air comming into the engine. This value is reported to the EEC

Knock Sensor -

L-MAF - Same as the GT MAF except it comes from a late model Lightning pickup truck, available in 80mm and 90mm sizes. These are recommended for supercharged engine combinations that need to meter much more air than a normally aspirated motor. Not recommended for a normally aspirated motor. Also requires a chip for proper functioning. Requires a new engine harness pigtail on vehicles 1995 and older.

MAF - Mass Air Flow sensor - Measures the airflow through the intake tube to the engine, it reports this to the EEC, which uses this data to control the timing of the spark and the amount of fuel delivered.

MAFs - see MAF

Pro-M - An aftermarket alternative to the Ford MAF. Pro-M sells units that are "calibrated" for use with different size injectors. They do this by changing the signal that is sent to the EEC so that the computer thinks it is getting a different amount of air than it really is. This may cause problems such as the fuel mixture going too lean, leading to detonation. The Pro-M unit itself is a very good unit, at one time better quality than the stock Ford unit. They will provide a flow sheet specifically for the piece you recieve, which can be used by a tuner to optimize the way your car runs. (Insert URL here)

TPS - Throttle Position sensor - Reports how far open or closed the throttle is to the EEC

TPS - Didn't you get the memo about the new cover sheet? Oh, and I'm going to need you to come in on Saturday.

--Suspension--

Adjustable Ride Control - Shortened "ARC" factory installed option that makes it possible to electronically adjust the firmness of the shocks.

Air Bags -

Mercon III Fluid -

Mercon V Fluid -

OD Band - see OverDrive Band

OverDrive Band -

Seperator Plate -

Shift Kit -

Shift Solenoids -

TC - see Torque Converter

TCC - see Torque Convertor Clutch

Torque Converter - A hydraulic device for providing the torque required at the driven shaft by transmitting and multiplying the torque from the driving shaft. This piece is what links the drive plate at the rear of the engine to the automatic transmission.

Torque Convertor Clutch -

Torque Convertor Clutch Solenoid -

TransGo shift kit -

Valve Body -

--Transmission Types--

4R70W - The name designation of the automatic transmission used with the 4.6('94 and up) and newer 3.8(years?) engines. It was also used in all MarkVIIIs and the '96 and up Mustangs. It is similar to the AOD with a wider gear ratio (the W is for wide) and electronic controls.

AOD - Automatic OverDrive - The name designation of the automatic transmission used with the 5.0('89 through '93) and earlier 3.8(years?) engines. This transmission was also used in FOX bodied vehicles

AODE - Automatic OverDrive with Electronic controls- This transmission was not used in any MN12 or FN10. The AODE only came in the following vehicles; 1992-1994 Town Car, Crown Victoria and Grand Marquis and the 1994-1995 Mustang (both the 3.8L v6 and the 5.0L V8)

T-45 -

T-5 -

--Wheels and Tires--

Backspacing - Measurement taken from the top of the lip of the inside of the wheel down to the mounting surface. This can also be found from the offset by dividing the wheel width by two adding the offset and then adding .5" to account for the wheel lip.

Bolt Pattern -

Camber -

Caster -

Drag-Radial -

Drag Slicks -

Offset - A measurement taken from the center of the wheel to the mounting surface of the wheel. Positive offset would put the mounting surface toward the outside of the wheel from the center while negative offset puts the mounting surface closer to the inside of the wheel. (A picture might be better for describing this)

Radial -

Toe (in/out) -

I'll just edit this post as i help out with the definitions. Will make it easier.

Caliper - the part of a disk brake system that applies pressure to the brake pads, which in turn apply pressure to the brake rotors (disks).

Brake Fluid - the fluid used by the hydraulic brake system to apply pressure to the brakes. Available in several grades. See Tech Article "Brake Fluid DOT Grades" for more information.

Brake Pad - The actual friction surface between the brake calipers and the rotors in a disk brake system. These wear down over time and must be replaced.

Brake Shoe - The actual friction surface between the wheel cylinder (hydraulic pistion) and the inner surface of the drum in a set of drum brakes. They serve the same purpose as brake pads, but don't wear out as quickly, and aren't as simple to replace.

Brake Drum - houses the wheel cylinder, brake shoes, and several springs. Rotates with the tire and the brake shoes apply pressure to the inner surface of the drum when the brakes are applied.

Brake Rotor - The rotor is the disk in a disk brake system. It rotates with the wheel, and pressure from the calipers is applied to this by the brake pads when the brakes are applied. (did that make sense?)

Brake Master Cylinder - This is where the fluid is stored (in the fluid resovior(sp?)) and where the pedal forces the fluid through the brake lines, to apply pressure to brakes the themselves.

For a little more accuracy:
Carrier - This contains the differential ("spider") gears and carries the ring gear of the ring/pinion set. All is contained within the differential housing or "pumpkin".

B Team - More skill, more results. A is only a starting point before progressing to B.

Member of the 'B-Team'. Finishing jobs the 'A-Team' can't handle.

The BOLD are the ones I filled in...
Easier to see the new stuff that comes in and just copy paste it into your document..

Some things need spellcheck 'cause I didn't know how to spell it..
You'll notice..

I've got the memo right here, it won't happen again.

I added AverageJoe's and Thyg0d's entries. Thanks for the help guys, if everyone helps to fill in just a few open terms, it will make a big difference.

Oh, the TPS thing was a joke from the movie Office Space, I just had to put it in there.

Lets keep this going.

SN-95 Mustang started in 94. Makes no sence, I imagine it stands for Sports North American Project 95, just so happened it came out for a model year near 95 to make it confusing. But the SN-95 started in the 94 model year as a 94 car. Fox Mustang ran from 79-93. Fox Thunderbird run from at least 83-88 but may have started before the aerobird of 83.

SOHC - reference to an engine with one cam to control the valves in each bank of cylinders. The cams are located in the cylinder heads.

DOHC - reference to an engine with multiple intake and exhaust valves for each cylinder utilizing two cams for the operation of the valves in each bank of cylinders. These cams are located in the cylinder heads.

Lightning - Ford's sport truck with production runs from 93-95(?) and from 99-04(?). The first production run featured a 351 Windsor engine while the 99-04 version had a supercharged 5.4L SOHC engine.

Mark VIII - the Lincoln made cousin to the MN-12 Thunderbirds and Cougars. This car came standard with the DOHC 4.6L with output ratings of 280 HP @ 5500 PRM and 285 Ft-lb of torque at 4500 RPM for the base models and 290 HP @ 5500 RPM and 295 Ft-Lb of torque for the LSC models.

Pinging - see detonation

Camshaft - a shaft containing a series of egg-shaped lobs that control the opening and closing of the exhaust and intake valves.

Aftercooler - device used to cool the intake charge of engines with either a supercharger or a turbocharger.

Intercooler - device used to cool the air in a multistage air compressor after the first stage of compression but before the second stage of compression. This term is commonly misused to reference an aftercooler.

Valve - device that opens and closes based on the input from the camshaft. This device allows air to travel into (intake valve) and out of (exhasust valve) the cylinders.

Valve Spring - Spring on top of the valve the keeps the valve pushed against the cam follower or rocker arm.

Offset - a measurement taken from the center of the wheel to the mounting surface of the wheel. Positive offset would put the mounting surface toward the outside of the wheel from the center while negative offset puts the mounting surface closer to the inside of the wheel.

Backspacing - Measurement taken from the top of the lip of the inside of the wheel down to the mounting surface. This can also be found from the offset by dividing the wheel width by two adding the offset and then adding .5" to account for the wheel lip.

I'm tired of typing, I'll come back for more contributions later.

The fuel travels in the following manner:

Through the fuel filter
into the Fuel pressure reguator
into the fuel rails
injectors open via EEC signal.

speedo gear- plastic gear located on the trans that must be calibrated for your tires and rear gears. All mn12s use a 7 tooth system. (link to calculator)

O2 sensors- There are two kinds of these, The first set are used to determine your Air/Fuel ratio, and allows the computer to fine tune the mix. They are NOT used at high throttle positions because they respond too slowly. The second set are used to determine the condition of the primary cataytic convertors. They can be bypassed with either a chip or a pair of MIL eliminators, allowing you to remove the primary cats. A car with EEC IV does not need MIL eliminators, as the do not have the second set of o2 sensors.

98 Audi A8 4.2Q in Racing Green Totalled

I buy my OEM Ford parts at 10% over dealer cost from Steve in White Bear Lake, MN.

EEC IV cars do not have 4 O2 sensors, only 2, one on each side before the primary cats. That description should probably be modified, probably shortened to a description of what they are and their function maybe so that it fits all MN-12's.
