FIGURE 23: Insert spacer (3).
FIGURE 24: Apply Loctite 242 to the thread of the pinion ring
nut (10) and tighten the nut onto the pinion.
FIGURE 25: Lock the wrench T1 (See drawing T1 p. 71), ro-
tate the pinion using a torque wrench, up to a minimum requi-
red torque setting of 600 - 800 N·m.

FIGURE 26: Apply onto the pinion (18) the special tool T1
(See drawing T1 p. 71) and with the help of a torque meter,
check the torque of the pinion (18).
Torque: 140 - 190 Ncm
If torque exceeds the maximum value, then the size of shim
“S1” (14) between the bearing (4) and the spacer (15) needs
to be increased. If torque does not reach the set value, in-
crease the torque setting of the ring nut (10) in different sta-
ges to obtain a maximum value of 600 - 800 N·m.
If torque does not reach the minimum value, then the size of
shim “S1” (14) needs to be reduced.
When calculating the increase or decrease in size of shim
“S1”, bear in mind that a variation of shim of 0.01 mm cor-
responds to a variation of 60 Ncm in the torque of the pinion
(18).

Using a faceplate, reset a dial indicator “DG” on a calibrated
block (whose known thickness is 25 mm).
