Fit transfer case (1) into place, by tightening fastening screws
(2) to the prescribed torque.
Selection and adjustment tie-rod assembling
Verify that the tie-rod (4) length ”X”, as measured between
the jointed head centres is not greater than 342 mm.
Lubricate the jointed head inside with MOLIKOTE 33 LIGHT
or MOLIKOTE G 72 grease, then connect the jointed heads
to levers (1 and 5).
Measure the distance ”y” between transfer case (3) outer
surface and ball pin (6) centre: it shall be ”y” = 146 ± 1 mm.
Otherwise, loosen nuts (2) and properly rotate tie-rod (4)
until the prescribed distance is obtained. Then tighten nuts (2)
to the prescribed torque, so that the vertical axes of the
jointed heads are aligned, with a maximum deviation of less
than 30˚ (lower).
Verify that spring (3) ends come into contact with selection
lever (4) or are at least 1 mm within the same. Otherwise,
loosen screw (1) so that spring (3) is correctly positioned, due
to plate (2) being released.

Mount the tool 99360521 (3) onto the rods (4, 5 and 6), on
the input shaft (1) and on the transmission shaft (10). Secure
the tool 99360521 (3) on the input shaft (1) with the retaining
ring (2) and with the screw (9) to the transmission shaft (10).
Hook the tool 99360521 (3) onto the lift. Apply the extractor
composed of the bridge 99341004 (13) and ties 99341012
(12) onto the rear cover (7). Use the screw of the bridge (13)
and work on the lift to extract the main shaft (11) from the
rear bearing. Set this assembly on the workbench. Remove the
tool 99360521 (3) and separate the transmission shaft (10),
input shaft with relative synchronizing ring and the rods (4, 5
and 6) from the main shaft.
