Once you have the flywheel ready to attach to the crank you can do the required balancing, or, in the case of these engines, the imbalancing.
Do not discard the auto trans flywheel from the M130; you will need it for matching of imbalance of the manual trans wheel.

The amount of imbalance of the flywheel varies from engine to engine, and is unique to each engine's rotating assembly, hence, when a flywheel is exchanged, the replacement wheel must replicate the imbalance of the original.
