(2) Using SST and a spring tension gauge, measure
the driven pinion preload.
SST 09326−20011
HINT:
Turn the driven pinion right and left 2 or 3 times to allow the
bearing to settle.
Preload (at starting):
New bearing
17.7 − 28.4 N (1.8 − 2.9 kgf, 4.0 − 6.4 lbf)
Reused bearing
4.9 − 8.8 N (0.9 − 1.4 kgf, 1.1 − 2.0 lbf)
If the preload exceeds than the specification, re-
place the bearing spacer.
If the preload is less than the specification, retighten
the nut 5−10° gradually a time until the specified
preload is reached.
If the maximum torque is exceeded while retighten-
ing the nut, replace the bearing spacer and repeat
the preload procedure. Do not back off the pinion
nut to reduce the preload.
Torque: 214 N·m (2,184 kgf·cm, 158 ft·lbf) or less
HINT:
Use a torque wrench with a fulcrum length of 50 cm (19.69
in.).
The maximum torque specification for without using SST
is 235 N·m (2,400 kgf·cm, 174 ft·lbf).
(c) Stake the lock nut.
2. ASSEMBLE RING GEAR MOUNTING CASE
(a) Install the transfer ring gear.
(1) Clean the contact surface of the mounting case.
(2) Heat the ring gear to about 100°C (212°F) in boiling
water.
(3) Carefully take the ring gear out of the water.
(4) Clean the contact surface of the ring gear with
cleaning solvent.
(5) Quickly install the ring gear on the mounting case.
HINT:
Align the matchmarks on the mounting case and connect the
ring gear.
(6) Install and torque the 12 bolts.
Torque: 97 N·m (985 kgf·cm, 71 ft·lbf)
(b) Checking the ring gear runout (See page MX−82).
