In theory it could be done. In practice it would be much easier to remove
the engine. It is a task that should be done by a very experienced shop,
which may exclude your local dealer.
But, I b'lieve all that really need be done is to replace the bolt holding
the pulley to the crankshaft with the upgraded bolt and properly tighten it,
using thread locker.
