98. Check and clean all components. Replace any
defective parts.
N
OTE: For correct lubrication of the ring (30), a
deflector (15) is fitted between the pinion (13) and
the bearing cone (7), in contact with the bearing
cup (Fig. 18).
99. Place the deflector (15) on pinion (13), and force-fit
the bearing cone (7) fully home into the shoulder
(Fig. 7). Fit the cone (4) into the bearing cup (3).
N
OTE: If the bearing cup (3) has been replaced, refit
the 540 / 1000 rpm pinions (see chapter 7). Fill the
housing to the correct oil level.
100. Preparing and shimming the pinion (13). Carry out
operations 30 to 45.
101. Take out the pinion (13) and assemble it with the
shaft (35) (Fig. 19), then fit the washer (5) and
screw (6). Tighten the screw to a torque of 50 Nm.
102. Refit the bearing cone (4), the coupler pinion (34)
and the needle bearing (28).
103. Fit the pinion assembly (13) and the shaft (35).
N
OTE: Check for the presence of the coupler
sleeve (31).
104. Position the washer (33), fit the circlip (32).

needle bearings (17) (20).
Position the double pinion assembly (14).
Place the washer (16) smeared with miscible
grease (“Amber technical” or equivalent).
106. Ensure that the channels in the pin (23) are not
obstructed; they are used for lubricating needle
bearings (17) (20) and the front bearing of the drive
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).
107. 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).
108. Smear the set screw (22) with Loctite 542. Tighten
to a torque of 28 - 43 Nm.
109. Clean the cover (10) mating face.
110. Smear the mating face of the housing with a
sealing product (Loctite 510 or equivalent).
111. Check for the presence of the bearing cup (8), fit
the cover (10) with screws (3) and tighten to a
torque of 130 - 170 Nm (Fig. 16).
112. Reconnect the pipes (1) (4) (Fig. 16).
113. Fit the locking screw (24) and the nut (25). Adjust
the fork (26), carry out operation 85.
114. Refit the lift cover (see chapter 6).
