I cannot create a PDF file. I am a text-based AI and do not have the capability to generate or manipulate image files. However, I can provide you with a list of semi-truck parts and descriptions that you could then use to create your own PDF, perhaps by finding images online and incorporating them into a document creation program like Microsoft Word or Google Docs.
Semi-Truck Parts Names and Descriptions
This list is not exhaustive, but it covers many major components. Remember to always consult your truck's manual and a qualified mechanic for any maintenance or repair work.
Engine & Drivetrain:
- Engine Block: The main housing for the engine's internal components. Image Description: A large, cast-iron or aluminum block with cylinders and various mounting points.
- Cylinder Head: The top part of the engine that covers the cylinders and contains valves, spark plugs (in gasoline engines), or injectors (in diesel engines). Image Description: A complex metal casting with valve ports and passages.
- Crankshaft: The rotating shaft that converts the linear motion of the pistons into rotational power. Image Description: A long, heavy shaft with counterweights and journals.
- Pistons: Moving components within the cylinders that compress the air-fuel mixture or air (in diesel engines) and convert the resulting pressure into motion. Image Description: Circular metal components with rings and a connecting rod attachment.
- Connecting Rods: Connect the pistons to the crankshaft, transferring force from the pistons to the crankshaft. Image Description: Rod-shaped components connecting the piston to the crankshaft.
- Transmission: Transfers power from the engine to the wheels, allowing for different gear ratios and speeds. Image Description: A large, complex gearbox with multiple shafts and gears.
- Clutch (Manual Transmissions): Disconnects the engine from the transmission, allowing the driver to shift gears. Image Description: A disc-shaped component that engages and disengages the transmission.
- Driveshaft: Transfers power from the transmission to the rear axles. Image Description: A long, rotating shaft often with universal joints.
- Differential: Allows the wheels to rotate at different speeds during turns. Image Description: A gear assembly that allows for different wheel speeds.
- Axles: Support the weight of the truck and transfer power to the wheels. Image Description: Large, heavy shafts that support the wheels.
- Wheels & Tires: Provide traction and support the vehicle's weight. Image Description: Large diameter wheels with specialized low-profile tires.
Chassis & Body:
- Frame: The main structural support for the entire truck. Image Description: A large steel framework that runs the length of the truck.
- Cab: The driver's compartment. Image Description: The enclosed area where the driver sits.

- Suspension: Absorbs shocks and vibrations from the road. Image Description: Springs, air bags, and shock absorbers that connect the frame to the axles.
- Brakes: Slows or stops the truck. (Includes various components like calipers, rotors, drums, and air pressure systems) Image Description: Calipers, rotors, drums, and brake lines.
- Steering System: Allows the driver to control the direction of the truck. Image Description: Steering wheel, steering column, and linkage connecting the steering wheel to the front wheels.
- Lights & Signals: Provide visibility and communication. Image Description: Headlights, taillights, turn signals, brake lights.
- Mirrors: Provide the driver with a wide view of the surroundings. Image Description: Large mirrors attached to the cab.
Electrical System:
- Battery: Provides power for starting the engine and other electrical components. Image Description: A large lead-acid battery.
- Alternator: Generates electricity to charge the battery and power electrical systems. Image Description: A generator that produces electrical power.
- Wiring Harness: A network of wires that connects all the electrical components. Image Description: A bundle of wires and connectors.
