Reply To: Removing Viking 3.5 Flywheel

[amuller]

You can use a knocker or a puller in most cases. On a really stubborn wheel you might need both a tight puller and to hit it. I generally would rather use a puller as it seems better not to shock the engine, especially ones with the antique type of steel magnets that may be weakened. But not all flywheels have puller holes. Lots of engines get damaged by botched flywheel removals. In any case a key point is to protect the crank. Rarely should a 2 or 3 arm puller be used to pull on the outer rim as that will probably distort the flywheel.
