1.    Clutch, cover washer (034 only)
In the near future a new cover washer
1127 162 1000 will be installed between the oil                         5
pump and clutch. It is designed to help prevent
consequential damage to the crankcase and oil                                                       3
pump in the event of a clutch spring failure. To
accommodate the cover washer, it was necessary to                      T0
modify the clutch carrier and the clutch shoe
retainers.
Service note                                                                                        2
The cover washer may be installed only together
with the modified clutch carrier and shoe retainers.
Do not attempt to fit the cover washer to the
previous clutch (with carrier 1125 162 3201) - it
must be installed without the cover washer.
Installation: The word “TOP” on the cover washer
must face the clutch.
