Sony CDP-S3 CD player mechanism issue

IN STRIPPING DOWN THE THREE-CD TRANSPORT MECHANISM, I HAVE PROBABLY PUT THE THREE TRAYS BACK IN THE WRONG ORDER.  THESE ARE PART NUMBERS     4-228970-02, 4-228-970-12,   4-228-970-22.  THE SERVICE MANUAL DOES'NT HELP.   OTHERWISE I HAVE NOT SET UP THE MECHANISM CORRECTLY!  CAN ANYONE HELP PLEASE.
