FIG. B.lll/9 TIGHTENING THE NUT (ITEM
c,,
FIGURE 36) WITH THE TORQUE WRENCH (F,
LONG TOOL NO. 779846) TO CHECK THE BEVEL
PINION BEARING SETTING
Install in the housing the caliper (Item F, Fig.
B.lll/11), block the right side bearing housing
complete with about 0.040" (1 mm) of adjust·
ment shims (Item Sa) with only three nuts
(Item C.) tightened to the torque of 41.2·45.5
ft.·lbs. (56·62 N•m) and then arrange the left
side bearing housing without adjustment
shims still with only three nuts (Item 0),
previously lubricated and arranged at 120
o
from each other. Cross-tighten the nuts (Item
D) with torque increments of 0.7 ft.·lbs. (.9
N•m) up to 4.3 ft.·lbs. (6 N•m) per nut and, at
the same time, turn the caliper by hand to
seat in the tapered roller bearings.
Arrange the caliper horizontally, turn the
knurled knob bringing the end of the pin in
abutment with the surface (Item E) of the
shaft and take the reading of the dimension
(Or) and its sign given by the pointer as the
knob stops turning.
Write down the correction factor (Item Oc,
Fig. B.lll/6) etched on the pinion face, ex·
pressed in mm. and preceded by the sign ( +)
or (- ), if different from zero.
NOTE: It is important to remember that 0.1
mm. equals 0.004 in.
Find the algebraic difference between the
measured distance (Item Or) and the correc-
tion factor (Item Oc): the result will be the
quantity of increment of reduction of the
thickness and the adjustment shim stack
(Item
s,)
to obtain the final shim thickness
(Item S, Fig. 8.11116).
