Flywheel Products

The flywheel is a crucial component in your vehicle, performing several very important tasks. The first job the flywheel assists in daily is in getting your engine started and ready to go. The starter uses the flywheel to turn the engine crankshaft, its pinion gear engaging with the ring gear at the perimeter of the flywheel. As the starter uses the ring gear to turn the flywheel, which is mounted on the engine crankshaft, the crankshaft is rotated through several revolutions, moving the engine parts through the combustion cycle to start the engine. After the engine is started and has begun to operate on its own, the flywheel will use its precisely weighted and balanced disc to keep the crankshaft turning smoothly between cycles of combustion, preventing it from slowing between piston firings. The flywheel has yet another important role to play, helping to form the connection between the engine and transmission that allows the torque power produced by the engine to travel through the transmission to the rest of the drive train to reach the drive wheels, where it is used to propel the vehicle. The flywheel is quite durable, but eventually daily driving will take its toll, wearing away at the teeth of its ring gear or causing stress cracking in its disc. We carry a great selection of flywheel replacements, both standard and custom, in our online catalog. Our terrific prices and expert customer service will make ordering your flywheel quick and easy whether you use our secure site or dial our convenient toll-free phone line.

Get a New Flywheel to Spin Your Engine Better

The flywheel transfers mechanical energy from the engine to the clutch plate. Gear shifting takes place when they make contact, whether you drive a manual or automatic transmission. If your car's flywheel us broken, it will cause your car to stall because you wouldn't be able accelerate. This portion will show the things you need to know when you're searching for a replacement.

The right size of the flywheel

Determine the size of the flywheel that is fit for your car. You should give the specific make, type, and year of your car when you shop so it will be easier to find. Another thing you can do is to remember the size of flywheel your car. You can easily compare it to know if it will fit on the flywheel holder or not.

The comparison between the two flywheel systems

The two kinds of flywheel systems are single and dual mass. The difference between the two systems is mostly about effect on your vehicle handling. Here's a more detailed approach on both systems:

  • Single mass
  • A single mass flywheel system performs well in a very high usage level. The design for a single mass flywheel and clutch is also easier for most vehicles. However, it produces more vibration to the drivetrain which can feel rough when you drive.

  • Dual mass
  • The advantage of a dual mass flywheel system is its smooth driving from lesser engine vibration. It can also decrease difficulty from the transmission and the drivetrain. These are all possible if the vehicle's engine is still made from stock parts. Otherwise, the modifications that give more power to the engine will make it difficult for a dual mass flywheel to reach the same level.

If you still have the original engine parts on your car, then the best option is the dual mass. For those vehicles that had been modified, the single mass flywheel is the best selection. For the single mass, the appropriate flywheel size would still be determined depending on the engine.

Aluminum or steel flywheel

These are the two typical materials used in a flywheel. To know which one is better, consider what type of car you drive. An aluminum flywheel is lighter, and gives better horsepower, so it's applicable for most race cars or a vehicle similarly designed. A steel flywheel on the other hand, is heavier and it will yield a higher amount of torque. This type of flywheel is good for off-road or utility vehicles.

Place a New Flywheel Back in Order

The flywheel is a car part responsible for transmitting energy from the engine to the transmission system. It may be a part rarely seen or heard, but this is very vital for performance. Luckily, here's guide to help you install a flywheel in your own garage.

Difficulty Level: High

Tools you'll need:

  • Impact wrench
  • Wrench set
  • Screwdriver set
  • Floor jack
  • Jack stands
  • Pliers
  • Oil pan
  • New flywheel

Step 1: Park your vehicle on a level surface, and engage the parking brake.

Step 2: Jack the car in front until it is possible to slide under and work comfortably.

Step 3: Use the impact wrench to remove the lug nuts and the front wheels of your car. Afterwards, remove the entire wheel hub for both wheels. Be careful when you place down the wheel hubs because the brake lines attached to them are sensitive.

Step 4:Remove the oil drain plug using the impact wrench, and place the oil pan below. Make sure the reservoir is empty before moving to the next step.

Step 5: Locate the lug nuts that hold the strut assembly to the axle, and remove the front struts. The axle should also be loose when you have separated it to the struts.

Step 6: Remove the stabilizer rods that hold the car's transmission. Use the pliers for small pins that are attached to each rod.

Step 7: Disconnect the wires attached to the engine that lead to the battery. The small screwdrivers are helpful in this part. Make sure you can still snap back the connections later.

Step 8: Locate the tranny in front of the engine. Make sure it is supported before you remove the bolts that hold it. Place it down and you will see the pressure plate covering the flywheel.

Step 9:Remove the pressure plate, the clutch disc and the flywheel.

Step 10: Install the new pilot with the bearings that came into the kit.

Step 11: Place all the parts back in order until you have dismounted the vehicle, and refill the engine oil.

Step 12: Start the engine, test drive, and observe if there are necessary adjustment to the installation.

This process will take an expert car junkie 5-6 hours for completion. It will probably take an average handyman 8-9 hours to complete this task.
