1. Deflector mounting (drive tube with sleeve,
   deflector, clamp)

A sleeve is fitted to the drive tube to define the
correct position for mounting the deflector. The                         1               3
sleeve increases the diameter of the drive tube in                                                    4116 . . . . . . .

(2") long.
Deflector and clamp have been modified to suit the
bigger diameter.                                                  ø 37,5 mm              ø 37,5 mm
