A ratcheting wrench can be used in any situation where you might otherwise use a box-end wrench. If you have a lot of nuts or bolts to tighten, a ratcheting wrench will greatly reduce the time it takes to do so.
What is the function of the master cylinder Asvab?
The master (brake) cylinder converts pressure on the brake pedal to hydraulic pressure in the brake lines .
What kind of wrench should be used to tighten engine?
The best way to tighten fasteners is with a device called a torque wrench .
Which engine component stores oil for lubrication?
Oil Pan / Sump :
Oil sump sits below the crankcase and stores the engine oil when the engine is not running. It is located at the bottom of the engine in order to collect and store the engine oil. The oil returns to the sump by pressure/gravity when the engine is not in use.
What is not part of a car drivetrain?
The powertrain consists of the power source (e.g. the engine) and all of the components that convert the engine's power into movement of the vehicle (e.g. the transmission, driveshafts, differential and axles); whereas the drivetrain does not include the power source and consists of the transmission, driveshafts, ...
Who uses wrench?
Wrenches are made in various shapes and sizes and are used for gripping, fastening, turning, tightening and loosening things like pipes, pipe fittings, nuts and bolts. There are basically two major kinds of wrenches: Pipe wrenches used in plumbing for gripping round (cylindrical) things.
Should you push or pull a wrench?
Always pull, rather than push , a wrench for greater control and balance. That way, if the nut or bolt should suddenly loosen, you're less likely to go flying. Never try to get more torque from a wrench by using a cheater bar or other device to extend the leverage.
What is the master cylinder's primary function?
The brake master cylinder, also known as the master cylinder, is a hydraulic pump. It feeds brake fluid into the brake circuit to convert the pressure on the brake pedal to the hydraulic pressure .
What are the three functions of the master cylinder?
The master cylinder, also known as the master brake cylinder, converts the pressure on the brake pedal to hydraulic pressure by feeding brake fluid into the brake circuit and controlling this according to the mechanical force. Master brake cylinders are used both in disc brakes and drum brakes.
What are 4 functions of a master cylinder?
develops pressure ,causing the wheel cylinder pistons to move toward the rotors or drum,after all the shoes or pads produce sufficient friction-it helps equalize the pressure required for braking,it keeps the system, full of fluid as a brake linings wear,it can maintain a slight pressure to keep contaminants from ...
What does oil lubricate in an engine?
The primary job of oil film lubrication is to ensure the engines components move smoothly, while minimising friction and component wear all at the same time. ... Engine oil transfers heat away from lubricated engine components such as bearings, pistons, rings, valve stems and cylinder bores during operation.
What would you tell the person who is trying to loosen?
What would you tell the person who is trying to loosen the rusty nut with the wrench? Move your hand farther from the nut . Four weights are tied together and hung from the ceiling.
What part of a car's cooling system cools the Pistons?
Cooling channels—The piston is cooled by oil flowing through a cooling channel or gallery incorporated into the piston. One or more oil spray nozzles feed oil into the cooling channel through inlet openings in the bottom of the piston. The cooling oil exits the cooling channel through one or more drain holes.
How much does it cost to fix a powertrain?
Because of the labor costs and the arts, you can expect to pay between $500 and $1,500 for a new powertrain control module and another $120, at the low end, for the total average labor cost. This means that the total pcm replacement cost comes out to between $620 and $1,620 total .
What's the difference between drivetrain and powertrain?
Basically, the drivetrain is what provides the power to move the wheels. The powertrain is made from the motor and the drivetrain .
What is the benefit of an AWD vehicle over other drivetrains?
4WD improves traction in dangerous driving conditions , such as snow, ice, rocks, and other scenarios that can make control difficult. By engaging both sets of wheels, traction and control improves. Additional weight contributes to better grip on the road.
