Figure 135 1 Position the bushing to insert on the drift (A) making the grub screw on it coincide with the seat (B) (Figure 134) on the bushing.
2 Position the guide bushing (E) and secure the guide bushing (G) (Figure 134) on the seat of the 7 th bushing with the plate (H). 3 While driving in the bushing, make the reference mark (F) match the mark (M). In this way, when it is driven home, the lubrication hole on the bushing will coincide with the oil pipe in its seat. The bushing is driven home when the 1 st red reference mark (D) is flush with the guide bushing (G). Rear 71725 Figure 137 The sequence for removing the bushings is 7, 6, 5, 4, 3, 2, 1. The bushings are extracted from the front of the single seats. Removal does not require the drift extension for bushings 5, 6 and 7 and it is not necessary to use the guide bushing.
For bushings 1, 2, 3 and 4 it is necessary to use the extension and the guide bushings. Position the drift accurately during the phase of removal. Figure 136 Assembly Rear 71723 To insert the bushing (6), proceed as follows: - Unscrew the grip (I) and the extension (N). - Position the extension (N) and the guide bushing (E) as shown in the figure. Assemble the drift together with the extension. To insert bushings 1, 2, 3, 4 and 5, proceed as follows: 77795 - Repeat steps 1, 2, 3. Base q November 2006 Print 603.93.641
