Does flywheel need to be balanced

[Terry Burtz, Calif]

Brent Terry and Marshall V. Daunt are correct.

1)Balance the crankshaft first.
2)Add the flywheel and balance the assembly by only removing weight from the flywheel.
3)Add the pressure plate and balance the assembly by only removing weight from the pressure plate

The new engine crankshaft is made from nodular iron which does not have harmonics (It will not ring like a bell when struck) and the 5 large diameter mains eliminate flexing and spring-back.
