Crankshaft, balance disc and flywheel are balanced together.

A new flywheel must be balanced to the same value of the one removed.

The balancing condition of a flywheel for manual transmission can be transferred to a flywheel for automatic transmission by static balancing (and vice versa).

1    Place old and new flywheels on top of each other that all bores align and both clutch surfaces face in one direction.

2   Transfer mark from old to new flywheel.

3 Apply balancing mandrel and bolt new flywheel with an offset of exactly 180° over old unit.

4 Let balancing mandrel with both flywheels oscillate on rolling device.

5 If an unbalance is found, drill so many holes in mass of new flywheel until the flywheels remain still without oscillating in any position.

The hole circle dia, the drill dia and the max drilling depth must be maintained (refer to table).

The dust bores (arrows) must not be drilled.
