Lightening Flywheel of Toyota Corolla Levin / Trueno AE101 20v AFM (Silvertop)
28th October 2004
The original flywheel came from the engine Toyota Corolla Levin / Trueno AE101 20v AFM 4A-GE (Silvertop) and it weights 6.8 kg.
It is sent to a C&C machine shop for lightening. The result is a 5.8 kg flywheel. Just like the Toyota Corolla Levin / Trueno AE111 20v MAP $A-GE (Blacktop) flywheel.

Below is the "Silvertop lighten flywheel". Notice the 6 pieces are removed according to examples set by the blacktop unit. However the lightening process is very conservative. The areas near the bolt holes are not as forgiving as the original 20v MAP flywheel, which is closer to the holes and less space. See the green arrows.
The removal is also not as close to the surface in contact with the clutch plate as oppose to the 20v MAP's unit. See red arrows.
The removal is also not as deep / low downward compared to the 20v MAP's unit. See yellow arrows.
However this lighten unit fair as light as the 20v MAP's flywheel because the center area is reduced. See purple arrows.
