10. Install the pinion lock tool, tool number 380000257 (1) .
11. Install wrench, tool number 380000268 on the
threaded adjustment ring.
12. Using a wrench on the pinion lock tool (1) , hold the
pinion against rotation, and using a torque wrench po-
sitioned exactly as shown in the figure on the threaded
adjustment ring wrench
(2) , tighten the adjustment
ring to a torque value of 294 N·m ( 217 lb ft ) while si-
multaneously rotating the pinion shaft to ensure that
the bearings are seated correctly.

13. With a torque wrench (1) on the pinion lock tool, tool
number 380000257 (2) , check that the pinion rolling
torque, without oil seal and relative dust seal ring is
0 N·m ( 0 lb in ) - 0.2 N·m ( 1.8 lb in ).
If the rolling torque is less than the prescribed value,
install a thinner adjustment shim shown in Figure
2 , if
the torque is greater than the prescribed value, install
a thicker adjustment shim.
14. Unscrew the threaded adjustment ring and install the
oil seal and the dust seal ring. Tighten the threaded
ring to a torque of
294 N·m ( 217 lb ft ), while simul-
taneously rotating the pinion shaft to ensure that the
bearings are seated correctly.
15. With a inch/pound torque wrench (1) on the pinion
lock tool number 380000257 (2) , check that the pinion
rolling torque with the oil seal and relative dust seal
ring is
0.5 N·m ( 4.4 lb in ) - 1 N·m ( 9 lb in ).
Finally, carefully stake the threaded ring and fit the
circlip on the drive pinion shaft.
