What does a crankshaft do?
Crankshafts and Camshafts The crankshaft is essentially the backbone of the internal combustion engine. The crankshaft is responsible for the proper operation of the engine and converting a linear motion to a rotational motion.
What happens crankshaft failure?
Vehicle is Stalling and/or Backfiring Along the same lines as the symptom above, a problem with your crankshaft position sensor could cause your vehicle to stall and/or backfire. Stalling is more common than backfiring as the interruption of the crankshaft signal can cause the engine to be cut off.
Where is the crankshaft located in an engine?
Located in the “bottom end” of an engine, the crankshaft harnesses the tremendous force of combustion (the violent burning of the air and fuel in the combustion chamber) by thrusting the pistons downward, causing the crankshaft to rotate. This rotation is the power source of an engine.
How are the journals of the crankshaft connected?
The rod journals are connected to the main journals by webs. The distance between the center of the main journal and the center of the crankshaft pin is called the crank radius, also called the crank throw. This measurement determines the range of piston travel as the crankshaft rotates – this distance from top to bottom is known as the stroke.
Why do you need counterweights on a crankshaft?
The real goal of balancing a rotating assembly is to make sure that the crankshaft counterweights offset the rotating and reciprocating forces created by pistons and rods. With today’s lightweight pistons and rods, accomplishing this usually involves removing mass from the crank counterweights.
Is it possible to balance a crankshaft perfectly?
While this technique works extremely well for most street and race 90-degree V8 engines, the truth is it’s nearly impossible to balance a crankshaft perfectly.
What does it mean when your crankshaft sensor goes off?
It’s another issue that indicates a malfunction of the sensor, and one of the crankshaft position sensor symptoms. In this case, your car will still run but the engine will turn off after some time. The misfiring will also occur the same way. If you keep ignoring the signs, the engine will shut off permanently.
Why is the position of the crankshaft so important?
The speed and position of the crankshaft are two key parameters that the car’s computer uses for engine management calculations. So, you may understand how important it is for the sensor to work without any glitch. Let’s learn about some crankshaft position sensor failure symptoms so that you can take action when there’s a problem.

How are crankshafts removed from the engine blocks?
Pressing the red arrow buttons will bring you back to the top of the page Crankshafts are removed from the engine blocks so a visual inspection of the crank casting can be done. Crankshafts with bad keyways, journals spun beyond machining specs or worn thrusts surfaces will be discarded.
