Have you obtained either the FSM (Factory Service Manual) as a book (Honda CR-Z 2012 Shop/Service Information), Anyone here have the FSM page they can send you as a PDF ( there was also a couple of postings that indicated the FSM can be accessed online) or have you talked to a mechanic that might have the information to remove it? It would be best to send the whole unit to the refurbishment company as you really don't know what else maybe out of specifications.
