(c) Using SST, firmly tighten the adjusting nut on the
drive pinion side.
ssr o9504-ooo1 1
(d) Check the ring gear backlash.
lf tightening the adjusting nut creates ring gear backlash,
loosen the nut so that backlash is eliminated.
(e) Place a dial indicator on the top of the bearing cap on
the ring gear side.
(f) Adjust the side bearing for zero preload by tightening
the other adjusting nut until the pointer on the indica-
tor begins to move.
(g) Tighten the adjusting nut 1 - 1llz notches from the
zero preload position.
(h) Using a dial indicator, adjust the ring gear backlash
until it is within specification.
Backlash: 0.10 - 0,15 mm (O.OO39 - O.OO59 in.l
NOTE: The backlash is adjusted by turning the left and
right adjusting nuts equal amounts. For example, loosen
the nut on the left side one notch and tighten the nut on
the right side one notch.
(i) Torque the bearing cap bolts.
Torque: 6OO kg-cm (43 ft-lb, 59 N.ml

(j) Recheck the ring gear backlash.
(0 Using a torque meter, measure the total preload.
Total preload:
ln addition to drive pinion preload
2 - 4 kg-cm 11.7 - 3.5 in.-lb, O.2 - 0.4 N.m)
Backlash: O.1O - O.15 mm (0.0039 - 0.O059 in.)
6. INSPECT TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION
(a) Coat red lead on 3 or 4 teeth at three different posi-
tions of the ring gear.
(b) Hold the companion flange firmly and rotate the ring
gear in both directions.
(d lnspect the tooth pattern.

Torque: 1,425 kg-cm (103 ft-lb, 140 N'ml
12. ADJUST DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the back-
lash between the drive pinion and ring gear.
Preload: New bearing 6.5 - 12.5 kg-cm
(5.6 - 10.9 in.-lbl
(0.6 - 1.2 N'ml
Reused bearing 4 - 7 kg-cm
(3.5 - 6.1 in.-lbl
(0.4 - 0.7 N'ml
lf preload is exceeds specification, replace the bear-
ing spacer.
lf preload is less than specification, retighten the nut
130 kg-cm (9 ft-lb, 13 N.m) at a time until the
specified preload is reached.
lf the maximum torque is exceeded while retightening the
nut, replace the bearing spacer and repeat the preload pro-
cedure. Do not back off the pinion nut to reduce the
preload.
Maximum torque: 2,4OO kg-cm
(174 ft-lb, 235 N'm)
CHECK DEVIATION OF COMPANION FLANGE
Maximum tateral runout: 0.10 mm (0.0039 in.l
Maximum radial runout: 0.10 mm (0.0039 in.l

(a) Select either a lock plate No. 1 or No. 2 whichever
will fit the adjusting nuts.
(b) lnstall the lock plate on the bearing caps.
Torque: 55 kg-cm (48 in.-lb, 5.4 N'ml
INSTALLATION OF DIFFERENTIAL
