Reassembly
72. Check and clean all components. Replace any
defective parts.
73. Refit the shaft (2) and the coupler sleeve (31) (if
disassembled).
74. Smear the screw (27) with Loctite 221 and tighten
(if disassembled).
75. Refit the cone bearing (4). Position the pinion (13)
prepared with the shaft (35). Place the coupler
pinion (34), the needle bearing (28), the washer
(33), and the circlip (32). Push on the pinion (13).
Position the washer (33). Fit the circlip (32).
76. In the pinion (18), place the spacer (19) and the
needle bearings (17) (20). Position the double
pinion assembly (14). Place the washer (16)
smeared with miscible grease (Amber technical or
equivalent).
77. Check that the channels in pin (23) are not
obstructed. They are used for lubricating the
needle bearings (17) (20) and the front bearing of
the driving pinion. Slightly engage the pin (23) in
order to hold the washer (16) in place. Place the
washer (21) coated with miscible grease. Centre
the double pinion assembly (14).
78. Definitively fit the pin (23) into the pinion assembly
(14) and into the fork (26) while ensuring the
correct positioning of the set screw hole (22).
79. Smear screw (22) with Loctite 542 and tighten to a
torque of 28 - 43 Nm.
80. Clean the cover (10) mating face.
81. Smear the mating face of the housing with a
sealing product (Loctite 510 or equivalent).
82. Check for the presence of the bearing cup (8).
Tighten screws (3) to a torque of 130 -170 Nm.
83. Reconnect the pipes (1) (4) (Fig. 16).
84. Refit the screw (24) and nut (25) on the fork (26).
85. Adjust the locking of the fork (26) (Fig. 15):
- Position the fork (26), with the locking screw (24)
on flat “M” of pin (23) (between the two locking
grooves), tighten the screw to compress the ball.
- Loosen the screw by one-quarter turn. Smear
the nut (25) with Loctite 241. Tighten to a torque
of 15 - 20 Nm.
- Check that the fork locks correctly.
