ADJUSTMENT AND ASSEMBLY
Judging from faulty conditions noted before disassembly and
what is found through visual check of bearing and gear tooth etc.
after disassembly, prepare replacing parts and proceed to reas-
sembly according to procedures as described below.
CAUTION:
 Bevel gear and pinion must be replaced as a set when
either replacement becomes necessary.
 When replacing taper roller bearing, replace as inner
race & outer race assembly.

Differential Case
Judging from abnormality noted before disassembly and what is
found through visual check of component parts after disassembly,
prepare replacing parts and proceed to reassembly. Make sure
that all parts are clean.
1) Assemble differential gear and measure thrust play of differ-
ential gear (2) as follows.
Special tool
(A) : 09900-20606
(B) : 09900-20701
Differential gear thrust play
: 0 – 0.37 mm (0 – 0.014 in.)
Left Side
Hold differential assembly with soft jawed vise and apply
measuring tip of dial gauge to top surface of gear (2).
Using 2 screwdrivers (1), move gear (2) up and down and
read movement of dial gauge pointer.
Right Side
Using similar procedure to the above, set dial gauge tip to
gear shoulder.
Move gear (2) up and down by hand and read dial gauge. CAUTION:
Perform press-fitting carefully so as not to tilt outer race.
[A] : Right side
[B] : Left side

2) If thrust play is out of specification, select suitable side
washer from among following available size, install it and
check again that specified gear play is obtained.
Available side washer thickness
0.90, 1.00 and 1.10 mm (0.035, 0.039 and 0.043 in.)
3) Put drive bevel gear (1) on differential case (2) and fasten
them with bolts (3) by tightening them to specified torque.
Use thread lock cement for bolts (3).
“A” : Thread lock cement 99000-32110
Tightening torque
Drive bevel gear bolts (a) : 80 N·m (8.0 kg-m, 58.0 lb-ft)

NOTE:
Before taking measurement, check for rotation by hand
more than 15 revolutions.
NOTE:
 When setting dial gauge to mounting dummy, tighten
screw lightly. Be careful not to overtighten it, which
will cause damage to dial gauge.
 With dial gauge set, turn dummy back and forth by
hand a couple of times and attain accurate 0 (zero)
adjustment.
 It is desirable that short pointer indicates beyond 2 mm
when long one is at 0 (zero).
