Subject        :   PREVENTING OFFSET ASSEMBLY 56T GEAR FROM RISING

Reason         :   To communicate the measures to be taken through servicing activity in the field to prevent noise and
                   the occurrence of E540 due to rising of the offset assembly 56T gear

Details        :   
                   There are cases where the 56T gear and the 19T/56T gear do not mesh properly due to rising of the
                   offset assembly 56T gear. If the 56T gear and the 19T/56T gear do not mesh properly, there can be
                   skipping of the gear teeth, and the shift motor drive will not be transmitted to the 56T gear, resulting
                   in noise and the occurrence of E540.

                   
                   If the end of the offset assembly link is pushed up due to some kind of force produced, the end of the
                   link will rise, and the 56T gear will also rise as a result. (Fig 2.)

                                                               If the end of the offset assembly link is pushed up due to some
                                                               kind of force produced, the end of the link will rise, and the
                                                               56T gear will also rise as a result.

                                                                                                                      -1/2-

                  The rising of the end of the link and the 56T gear was prevented by the addition of an E ring (XD2-
                  1100-322) to the 56T gear shaft. (Fig. 3)


                                                                                  E ring (XD2-1100-322)

Servicing    : When the aforementioned symptoms occur, correct the rising of the offset assembly 56T gear.
               However, when making this correction, check that the 56T and 19T/56T gear teeth had not broken off
               and replace the gears if necessary. Also, if the same symptoms recur after correcting the rising of the
               56T gear, replace the offset assembly by following the procedure, "5. Removing the Shift Tray
               Assembly", in Chapter 3 of the Service Manual (Multi-Output Tray-C1 / FY8-13EB-000).
