FLYWHEEL TOLERANCE- WHAT IS IT? WHY IS IT IMPORTANT?

Whatever material flywheel is made of,flywheel must be within specific tolerance to operate at its best performance. Notall tolerances are same, which illustrates every producer has a specific tolerance for its own flywheel manufactured. However, why does flywheel need to be machined to certain tolerance, and will it be safe to exceed that level?

Z: Specific tolerance is needed to maintain balance and alignmentwith additional moving components in drivetrain, since flywheel proves to be aconstantly moving mechanical part and is a sequence of drivetrain.

N: Flywheel contributes to performance a lot, and to drivability of clutchsystem. Flywheel is regarding machining and manufacturing tolerance, soparallelism and concentricity turns out to be vital measurement standards. The tighter or closer to zero the tolerance is, the more balanced the unit will be. This indicates that flywheel will not need extra balancing after machining. Rotational integrity, and the ability to provide perfectly flat surface for clutch disc to optimize wear and performance are maximized. Proper step and recess dimensions can make sure clutch actuation is clean and consistent, and can promote maximum clamp load. They maintain a one-one-thousandth machine tolerance to guarantee perfect rotational integrity, fast clutch seating and maximized drivability.

D: Avoiding premature-wear, ensuring correct operation and fitment,and clutch engagement are some particular reasons why flywheel must be machinedto specific tolerance. The correct tolerance should be matched to OEM tolerance, although this will vary depending upon application. One particularly salient example of this is car’s driveline set-up or clutch kind that is being used, which I mean pull versus push style.

Their flywheel options are designed as OEMreplacement, which illustrates they will meet or exceed factory tolerance. Theproducing procedure enables flywheels maintain tighter tolerance in many areas, which original equipment cannot. When machining a part versus casting one, the changes in final product are minimal. When got from CNC machines, machined parts are generally finished products which do not need extra work.
