ACT Flywheel

The ACT flywheel is bolted to the rear of the crankshaft and is positioned within the bell housing of the transmission. It is responsible for 'smoothing' out the pulses of energy that is provided by the combustion in the cylinders. It is also an energy provider to the compression stroke pistons. The actual punching, shearing and forming are done in only a fraction of the operating cycle. The speed of the flywheel during the longer, non-active period is built up slowly by a comparatively low-powered motor. Large amount of the required energy is provided by the flywheel as the press operates.

The component is actually a disc shaped and affixed around its parameter is the ring gear. This ring gear is engaged by the starter drive which then leads to the turning of the flywheel, rotating the crankshaft and imparting the initial starting motion to the engine. Servicing the flywheel requires that you remove the transmission, torque converter or clutch assembly. The torque converter is bolted to the flywheel on vehicles with automatic transmission. On the other hand, standard transmission vehicles equipped with a clutch has the clutch assembly that is not bolted to the flywheel. The ring gear around the flywheel is equipped with teeth to enable the starter to engage.

Modern cars commonly have sensors found on the bell housing that tell the engine of computer the engine rpm and when to fire the spark plugs. The engine will not start if one of the sensor pickups breaks on the flywheel. One thing that you must check first when your car suddenly dies is the spark. In the absence of spark, check the flywheel. If your flywheel is in big trouble and you need a replacement, Part Train is here to give you just what you need. We have a complete line of ACT products including the ACT flywheel.
