Ready to ShipW140 car parts refer to the components and accessories used in the Mercedes-Benz S-Class models produced from 1991 to 1998. The W140 S-Class is known for its advanced technology, luxury features, and high-quality engineering. Here are some common categories and types of W140 car parts:
Engine Components:
These include the main components of the car's engine, which is responsible for generating power to drive the vehicle. The W140 series had a range of engines, including V6 and V8 petrol engines, as well as V12 engines in higher-end models. The engine parts include:
Cylinder heads: These are placed on top of the cylinders and hold many important components, including valves, spark plugs, and fuel injectors.
Valves: They control the intake of air and fuel into the cylinders and the exhaust of gases out of the cylinders.
Camshafts: These are responsible for opening and closing the valves in sync with the pistons' movement in the cylinders.
Engine blocks: These are the main bodies that house the cylinders, pistons, and other important components.
Oil pans: These are found at the bottom of the engine and store the lubricating oil used to reduce friction between moving parts.
Timing chains or belts: These connect the crankshaft and camshafts, ensuring their synchronous rotation to control valve timing.
Transmission Parts:
This includes parts that are used to change gears and transmit power from the engine to the wheels, allowing for smooth acceleration and deceleration. The W140 series used automatic transmissions with several gears, controlled electronically for precise and comfortable shifting. Transmission parts include:
Torque converters: These connect the transmission and the engine, allowing for smooth gear changes and transfer of power.
Transmission oil cooler: This cools the transmission oil, ensuring stable and precise gear shifting.
Control unit: This controls and coordinates gear shifting based on the engine and driving conditions.
Clutches: These connect and disconnect the engine and transmission, allowing for smooth gear changes.
Gear sets: These are responsible for changing the transmission gears to suit the engine's power and the car's speed.
Suspension Parts:
This includes parts that hold the wheels to the car body, absorbing shocks and impacts from the road. This ensures a smooth ride and good vehicle control. The W140 series used an independent suspension system with air springs and dampers for adjustable height and comfort. Suspension parts include:
Spring coils: These store and absorb shocks from road bumps and irregularities.
Shock absorbers: These dampen the shocks from the springs, ensuring a smooth and stable ride.
Anti-roll bars: These connect the left and right wheels and help reduce the car's body roll when cornering.
Ball joints: These connect the wheels to the suspension arms, allowing wheel rotation and vehicle control.
Suspension arms: These connect the suspension parts together and maintain the wheels' position relative to the car body.
Brake Parts:
These include parts that slow down or stop the car. The W140 series used disc brakes on all wheels, ensuring strong and stable braking performance. Brake parts include:
Brake pads: These press against the brake discs to create friction and slow down the wheels.
Brake discs: These are rotated by the wheels and are slowed down by the brake pads.
Brake calipers: These hold the brake pads and apply pressure to slow down the brake discs.
Brake lines: These carry brake fluid and connect the brake pedals to the calipers, transmitting force to brake.
Brake booster: This amplifies the force from the brake pedal to ensure strong and stable braking.
Specifications of W140 car parts vary depending on the part in question. Here are some general specifications to expect:
Engine:
The W140 series had six engines. The first was the M104 inline-six engine. It had a 2.8-liter displacement and produced 142 hp. The second was the M103 inline-six engine. This one had a 3.0-liter displacement and produced 188 hp. The third was the M112 V6 engine. It had a 3.2-liter displacement with 224 hp. The M104 inline-six engine had a 4.2-liter displacement and produced 275 hp. The fifth was the M119 V8 engine. It had a 5.0-liter displacement with 394 hp. The last engine was the OM603 inline-six diesel engine, which had a 3.0-liter displacement with 188 hp.
Transmission:
The W140 had a 4-speed automatic transmission. It was known for its smooth shifting and high road performance.
Suspension:
The W140 had an air suspension system in some models. It had a pneumatic spring unit with a bellows that inflated and deflated to support the vehicle's weight. The suspension system offered a comfortable ride and was adjustable.
Brakes:
The W140 models had ventilated disc brakes in the front and rear. Some models had an anti-lock braking system (ABS).
Tires:
The W140 series used various tires depending on the model and year. However, the tires had a size of 215/70 R15 to 235/60 R16.
Regular maintenance checks on W140 car parts are crucial to ensuring the vehicle runs smoothly. Here are some maintenance tips:
Engine:
Check the oil levels regularly. Ensure the oil change is done every 5,000 to 7,500 miles. Also, replace the air filter every 15,000 to 30,000 miles.
Brakes:
Inspect brake pads and rotors every 10,000 miles. Look out for any signs of wear and replace them if need be.
Tires:
Check tire pressure every month. Ensure the tire pressure is within the recommended range. Also, rotate the tires every 5,000 to 10,000 miles for even wear.
Suspension:
Inspect the suspension components every 20,000 miles. Look out for any signs of wear or damage.
Transmission:
Check the transmission fluid levels every 15,000 to 30,000 miles. Change the transmission fluid and filter as recommended by the manufacturer.
Electrical System:
Inspect the battery terminals and cables every 10,000 miles. Look out for corrosion or damage and clean or replace them as needed.
