Flywheel : A flywheel bolts directly to a crankshaft and is used on automobiles to spin the automatic transmission’s torque converter, transmission input shaft or the manual transmission’s clutch. Flywheels are commonly fitted with a ring gear for the starter to use to help spin the engine for starting. Some flywheels are very thin and considered flex plates. The main job for most flywheels are to help add weight to the engine crankshaft to help with centrifugal force for movement of the internal engine, connect the transmission to the engine and help the starter be able to rotate the engine when engaged.
Flywheel problems are rare but do occur. Thin flywheels can break around the crankshaft bolts causing a loud racket while the engine is running, no movement of the car or a no start since the engine is not spinning when the starter is engaged. Standard shift flywheels can be damaged by a bad clutch or normal wear and tear from using the clutch. Some standard flywheels can be refashioned to specifications and be reusable. Some flywheels also develop a bad spot in the ring gear. In some cases a new ring gear may be available otherwise the flywheel must be replaced. This problem will sound like a grind noise while engaging the starter. Whatever type of flywheel or flywheel problem you have, Guy’s Automotive can get you going.
