What are the holes in a flywheel for?

These holes are for balancing purpose. If the flywheel is not balanced, then during high speeds, it will generate unbalanced forces on the shaft on which it is fitted. By removing some portion of the flywheel in the form of these holes, it gets balanced.

How is the flywheel connected to the crankshaft?

Flywheel is just a metallic disc which stores rotational kinetic energy form crankshaft. It is connected with help of bolts to the crankshaft.

Can you drill holes in a flywheel?

Premium Member. The pressure plate should be located to the flywheel with dowl pins. The bolts only provide clamping and retention, the pins locate it properly. If you’ve located the plate properly with the dowel pins, then drilled your holes, it should be fine.

What happens when a flywheel breaks?

If your flywheel is going bad, a smooth pedal is not what you will feel. You may feel vibration as soon as you place your foot on the clutch or when you press down on the clutch. The vibration tends to get stronger as you push on or engage the clutch pedal.

What is a flywheel in physics?

A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed.

What does the flywheel do in a car?

The mass of the flywheel applies inertia to keep the engine crankshaft turning between each of these piston firings, so the rotation speed of the crankshaft is kept constant and the engine runs smoothly. Flywheel does some specific functions in a car. Source: Youtube 3. Engine Balancing

Why is the crankshaft at the back of the flywheel?

Since the mass and stored energy of the rotating flywheel is at the back of the crankshaft, the rear of the crankshaft is stabilised; however, the result of this is that the distortion of the crankshaft is amplified towards the front of the crankshaft.

How do dual mass flywheels work?

Dual mass flywheels were introduced primarily to reduce engine vibrations that damage manual gearboxes in various ways, with the degree of damage being largely proportional to the amplitude of the vibrations.

What is the specification of a flywheel?

The specification of the flywheel depend on all sorts of things like engine design, number of cylinders (with more, the power stroke is more evenly divided), RPM of operation etc. It also depends on use cases, eg , like in racing]
