What Is A Crankshaft?
A crankshaft is a part in a reciprocating engine that rotates due to the reciprocating motion of the pistons. However in a pump, the crankshaft's motion causes the piston to move back and forth.The crankshaft is connected to the pistons by "crankpins" which have an offset axis allowing this conversion of motion to be accomplished. Since the common four-stroke cycle of the reciprocating engine isn't continuous, the crankshaft is often connected to a flywheel which is used to store rotational energy in order to reduce the pulsation or choppiness of the pistons.
What are the symptoms of a broken crankshaft?
Your “Check Engine” Light is Blinking.
It's Difficult to Get Your Vehicle to Start.
Your Vehicle is Stalling and/or Backfiring.
The Engine is Making Your Vehicle Vibrate.
If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. This is usually a symptom of a wiring problem, however a bad crankshaft position sensor can also produce this symptom.
