You shouldn't have to do anything, assuming that instance3 is a replica of instance1 or instance2, it should be automatic. You do have to wait for the synchronization to happen, and you should be seeing messages in the various Solr logs (particularly instance3 and the leader of the shard). What do the logs say?
Now, if these are different _shards_ it's a different story, but that doesn't appear to be the case from your description.
