Torque Converters For Sale The torque converter in your vehicle acts as a hydrodynamic fluid-coupling device. Converters are found between the engine and transmission in automatic vehicles. They take the place of mechanical clutch systems found in standard transmissions. The coupler also multiplies torque during acceleration, acting as a reduction gear. Components in a torque converter: The stator in a converter is the component that makes the difference between a fluid-coupling system and one that converts or multiplies torque. If the stator is not working, there will be no change in the amount of torque. This portion of the system changes the fluid flow and allows the drive wheels to receive more torque than is actually produced by the engine alone.The cover of the torque converter is located towards the engine side of the assembly. It provides the connection to the flywheel of the engine and holds the fluid needed for operation. While the cover does not actively produce torque, it must be able to withstand the high hydraulic pressure produced by the converter. It must also be able to withstand the thrust and torsional stress of the system.The impeller pump is located on the transmission end of the converter. This pump contains the fins that force fluid to the turbine. The turbine is attached with a spline from the input shaft on the transmission to the drive train of the vehicle. Movement of the turbine allows vehicle movement. Some converters also use a temporary locking mechanism that reduces slippage and increases fuel economy. Signs of converter failure: A defective converter can cause your transmission to slip. You may also notice surging or lurching. A delay in shifting, most noticeable when shifting from park into […]
Throttle Body Assemblies For Sale
Throttle Body Assemblies For Sale In order for your engine to run, it requires air and fuel, with a spark to ignite the compressed air-fuel mixture. A throttle controls the amount of air that is drawn into the system. Common throttles use a butterfly valve but can use a pinch valve or barrel-type. This valve is part of the throttle body assembly. Engines with fuel injection use a throttle body assembly that is often located between the air filter assembly and the intake manifold of the engine. A throttle valve is also used in carbureted engines. As you depress the accelerator, or throttle pedal, on your vehicle the valve opens to allow more air to flow. As more air enters, the amount of fuel increases to meet the required ratio. Electronic Control Units (ECU) Some vehicles use direct linkage from the accelerator pedal to the throttle to control the amount of air entering the system. Electronic throttle control systems use a motor to control the throttle linkages. In this system, the accelerator is connected to a sensor that sends information to the ECU. The ECU adjusts how much the throttle will open based on this signal. Throttle Body Injection (TBI) TBI systems are similar in design to carburetors. This version uses one or more fuel injectors set on top of the assembly. The injectors spray fuel through the valves, along with the air, for compression and combustion. As a note, Ford uses the term CFI instead of TBI. Multi-Point Fuel Injection (MFI) throttle bodies In an MFI system, the throttle body only controls the air that enters the system. The fuel injectors are separate from the assembly. Idle Air Control (IAC) Some engines use a […]
Timing Belts For Sale
Timing Belts For Sale An internal combustion engine contains a number of parts that move and spin at tremendous speeds. In order for the engine to run properly, these moving components must be synchronized, much like the gears in a clock. The job of synchronization falls on the timing belt, and if the timing belt fails, serious damage to your engine can result. Unlike the belts that drive your alternator or air conditioning compressor, the timing belt is not visible upon opening up the hood. It is located behind the accessory belts, guarded by plastic or metal covers. As such, accessing the timing belt usually requires quite a bit of time and disassembly. The typical timing belt requires that you remove, at a minimum, one of the front tires, the crankshaft pulley, the accessory drive belts, and the protective cover or covers. It is also common to have to remove engine mounts, the valve cover or covers, some of the belt-driven accessories, the air box, and/or other components as well. This is why it costs so much to have the job done at a garage. At $75.00 per hour for labor, removing all of this stuff and putting it all back into place once the new belt is on can put a comma in your repair bill. This is also why changing the timing belt yourself can save you so much money, because the lion’s share of the cost is labor. Timing belt replacement intervals vary from vehicle to vehicle. The standard used to be every 60,000 miles. However, improvements in technology and in belt materials have extended the change interval on some vehicles to as much as 90,000 miles or more.
