A flywheel is a rotating disc that collects and stores energy as it spins. By storing energy, flywheels allow the clutches in cars, trucks, and heavy-duty vehicles to run efficiently and smoothly. Attached to the engine’s crankshaft, flywheels are responsible for several functions within a vehicle. Its main function is that a flywheel transfers power from the engine of the vehicle to its transmission. A flywheel also allows the engine to start by the gear on the outside of the flywheel, engaging the starter motor. Another function is that the flywheel provides balance to the engine. Lastly, the flywheel plays a key role in allowing the clutch assembly to work smoothly.

Since 1960, HR Clutch has been providing economical solutions to all of your clutch and clutch component problems. We serve clients in Pennsylvania, New Jersey, Delaware, New York, and across the US and aim to educate our customers about the essentials of clutch parts, including flywheels. Continue reading below to find out more about flywheels, reconditioned manual flywheels, automatic flywheels, resurfacing for flywheels, high-performance lightweight flywheels and bronze inserts installed into aluminum flywheels.

Resurfacing for Flywheels
A common reason a clutch “chatters” is because the flywheel has not been resurfaced. A flywheel should be resurfaced each time a new clutch kit is installed. Most times a flywheel can be resurfaced several times before replacing, thereby saving you money. However, it is very important to examine the flywheel before resurfacing. Look at the flywheel face for heat checking, the depth of the wear mark, and the flywheel side of the clutch disc for any interference. Remember, in a hydraulic clutch application to use a flywheel shim to compensate for the amount machined off. It is always a good idea to use a micrometer to get the thickness before resurfacing. We have an extensive database on flywheel specifications. At HR Clutch, all flywheel resurfacing is done on the premises. We take out the guesswork when it comes to resurfacing or replacing your flywheel.

New Manual Flywheels
When a flywheel can no longer be resurfaced, it needs to be replaced. HR Clutch carries a wide variety of new domestic and foreign flywheels. These all come with new starter gears.

Reconditioned Manual Flywheels
We can refurbish flywheels by replacing the starter gear, removing broken studs, and balancing the flywheel to your clutch assembly. As mentioned above, the flywheel is used to start the engine. Gear teeth, also known as the ring gear, are pressed on the outside of the flywheel. The gear is what the starter motor turns in order to start the engine. Missing or damaged teeth on the gear can interfere with reliable starting. We will remove your old gear and replace it with a new gear, saving you the cost of a new flywheel.

Automatic Flywheels
HR Clutch provides customers with the largest selection of automatic flywheels available on the market today. We stock a wide variety of domestic and foreign flywheels, with new items added weekly.

High-performance Lightweight Flywheels
The advantage of having a lightweight flywheel is that it allows quicker engine revving while reducing rotating mass. In particular, this type is ideal for street and drag racing cars. Call us today to find out more about our selection of high-performance lightweight flywheels.

Bronze Inserts Installed into Aluminum Flywheels
Aluminum flywheels need the proper care in order to be up to par in performance standards. At HR Clutch, we’ll replace your existing steel insert and then customize a new insert for your aluminum flywheel. So in no time flat, you’ll be out and driving on the road again.
