Flywheel Information

Solid and Dual Mass Flywheels
Today most vehicles come with a Dual Mass flywheel, this flywheel has a rubber center that seperates the 2 halves of the flywheel. This rubber isolator allows much more smooth clutch engagement and transition. The Dual Mass flywheels also weigh much more (up to 50lbs) than a traditional solid flywheel and for those looking for some additonal performance, we reccomend upgrading to a solid lightweight flywheel and clutch kit.

The flywheel is bolted to the crankshaft and is located within the bell housing of the transmission. To service the flywheel you will need to remove the transmission, and clutch assembly. On a standard transmission vehicle equipped with a clutch, the clutch assembly will bolt to the flywheel. When replacing the clutch, be sure to check the rubber on the dual mass flywheel, as this rubber does tend to wear out after time.

On newer vehicles there are sensors located on the bell housing that tell the engines computer the rpm of the engine and when to fire the spark plugs. If one of the sensor pickups breaks on the flywheel, it will cause the engine to not want to start. mechanics in the past have spent hours troubleshooting a vehicle that has a bad flywheel pickup. If your car or truck one day out of the blue fails to start, or you car just dies on the road! First check for spark, if you have no spark, especially on German and Japanese cars and truck, you may want to check the flywheel pickup for damage.
