Bevel Gear Backlash Adjustment
Backlash between bevel gear and pinion is
checked as shown in Fig. 16-24. Note that
differential case assembly is mounted in the
normal manner, and fastened down by tighten-
ing the side bearing cap bolts to 1.0 2.0 kg-m
(7.5 14.0 lb-ft). At this time, screw in each
adjuster till it contacts bearing outer race so that
outer race is prevented from inclining. The dial
indicator spindle is pointed squarely to “heel”
on drive side (convex side) of gear tooth. Hold
bevel pinion rigidly, and turn gear back and
forth.
The dial indicator reading, which is bevel
backlash, must be within this range:
I
Bevel gear backlash
0.10 0.15 mm
(0.004 0.006 in.)
Fig. 16-24
To increase or decrease backlash for adjustment,
displace bevel gear toward or away from pinion
by running in one adjuster and running out the
other adjuster by equal amount.
Turning the adjuster one notch changes backlash
by about 0.05 mm (0.002 in.).
CAUTION:
l Adjust preload on side bearing during
back-lash adjustment: mount special tool
on drive bevel pinion as shown in Fig.
16-23 and measure using spring balance
If reading at the instant bevel gear
starts moving is within the range given
below, side bearing preload is acceptable.
Referring to the graph, for example,
when the drive bevel pinion bearing
preload measured as shown in Fig. 16-
23 is 2.6 kg (5.73 lb), drive bevel pinion
bearing preload (kg) + bevel gear side
bearing preload (kg) should be 2.8 3.2
kg (6.17 7.05 lb).
l
Upon completion of this adjustment, be
sure to tighten bearing cap bolts to 7.0
10.0 kg-m or 51.0 72.0 Ibft.
