Abstract
A wellbore tool, a wellbore fluid treatment string and a method with an indexing mechanism including a crown ratchet sleeve. The indexing mechanism can be shifted through one or more inactive positions before finally shifting into an active condition. The indexing mechanism is particularly useful with a plug that lands in a seat to impart an axially directed force on the mechanism before passing through the seat.
