Dana Holding Corporation ASM-0007E - 123 Axle Service Manual
FIGURE 29: Heat the external bearing (3) to a temperature of
about 212°F (100 C°) and fit it on to the pinion (5) to complete
the pack as shown in the figure above.
NOTE:
Lightly lubricate bearing (3) with SAE85W90 oil.
FIGURE 30: Install the flange (10) onto the pinion (5) without
sealing ring.
FIGURE 31: Apply wrench to the ring nut (1) and bar-hold T1
(See drawing T1 p. 58) to the pinion (5). Lock the wrench T1
(See drawing T1 p. 58) and rotate the pinion using a torque
wrench, up to a minimum required torque setting of 800 -
1000 N·m.

FIGURE 32: Apply onto the pinion (5) the bar-hold and with
the help of a torque meter, check the torque of the pinion (5).
Torque: 120 - 180 N·cm
If torque exceeds the maximum value, then the size of cali-
brated spacer “S1” (7) between the bearing (6) and the spa-
cer (8) needs to be increased. If torque does not reach the
set value, increase the torque setting of the ring nut (1) in dif-
ferent stages to obtain a maximum value of 800 - 1000 N·m.
If torque does not reach the minimum value, then the size of
calibrated spacer “S1” (7) needs to be reduced.
When calculating the increase or decrease in size of calibra-
ted spacer “S1”, bear in mind that a variation of calibrated
spacer (4) of 0.01 mm corresponds to a variation of 60 N·cm
in the torque of the pinion (5).
FIGURE 33: Make positional marks across nut (1) and pinion
(5) tang; then remove nut and flange (10)
