Vehicles with manual transmissions rely on several components to power and move the car or truck, including flywheels. A flywheel is essential in manual transmission systems because it retains kinetic energy from spinning. The reserved energy helps power up the car when the engine starts and gains speed while running. Here's what you should know about this essential component.

What Does a Flywheel Do?

In most vehicles with manual transmissions, the flywheel is an inch-thick metal disc that runs about a foot in diameter. The auto part could be made of various metals, including steel, aluminum, or cast iron, so its weight can vary from 10 to 40 pounds. You can find the component fixed to the end of the crankshaft in the engine attached to the auto transmission inside the bell housing. 

The flywheel has several functions. First, it provides sufficient rotational energy to keep the engine running and prevent stalling when you remove your foot from the accelerator. The component also adds weight to the crankshaft to smooth and balance the engine's operation. Thanks to its connection to the clutch, you can also rely on the auto part to transfer power to the wheels for them to move. 

What Are the Most Common Problems That Flywheels Develop?

Flywheels are designed to be durable and powerful, but that doesn't mean they never have problems. The good news is that you shouldn't have to repair the component frequently. However, a leak in the rear main crankshaft seal or the seal along the transmission's front input can leak oil onto its surface. The lubricant could cause the clutch to slip, leading to excess heat and friction. The chain reaction caused by the friction could cause hot spots or warping to develop on the flywheel, causing the engine to vibrate when you accelerate.
