Buyer's Guide to Mopar® Crankshafts
What Mopar® Crankshafts Do
Without the crankshaft, your engine wouldn't be of much use. That's because no part of your combustion engine's operation occurs without the crankshaft putting things in motion. The crankshaft is a hardened steel shaft that runs the full length of your engine. It converts the vertical motion of the pistons into the rotational movement that moves your car, truck, van, or SUV's wheels -- which is what propels you down the road.
How Mopar® Crankshafts Work
The crankshaft rotates inside the engine, while pistons located in the cylinders move up and down. Those pistons are connected by rods to rod bearing journals, which are strategically staggered to move the pistons in rhythm while balancing the engine's weight. Finally, the crankshaft works in sync with the camshafts, thanks to a sprocket that helps them work in tandem.
How to Spot a Faulty Crankshaft
Even the highest quality crankshaft can go bad, especially if it's not properly lubricated. Signs of trouble include:
- Low oil pressure levels
- Your engine makes knocking sounds
- Difficulty starting your vehicle
- Intermittent stalling
- Rough engine idling
- Worsening fuel efficiency
- A seized engine
- The ""Check Engine"" light comes on -- though this is a generic alert that requires further investigation to diagnose the cause
