(c) Using SST, tighten a new transfer gear nut (at a standard
torque.)
SST 09326-2001 1, 09556-16030
Torque:
277 to 378 NVm (2,820 to 3,855 kgfVcm, 204 to 279 ftVlbf)
NOTICE:
Do not stake the transfer gear nut.
HINT:
Use a torque wrench with a fulcrum length of 750 mm (29.53 in.)
50. INSPECT AND ADJUST DRIVEN PINION PRELOAD
(a) Using SST and a torque wrench, measure the initial
torque of the driven pinion.
Preload (at starting):
New bearing:
1.1 to 1.6 NVm (11 to 16 kgfVcm, 9.7 to 14.2 in.Vlbf)
Used bearing:
0.9 to 1.4 NVm (9 to 14 kgfVcm, 8.0 to 12.4 in.Vlbf)
HINT:
Use a torque wrench with a fulcrum length of 160 mm (6.30 in.)
NOTICE:
Measure preload after rotating the bearing both clockwise
and counterclockwise to make it fit.
(b) If the preload is too large, replace the transfer pinion
bearing spacer with a new one.
(c) If the preload is too small, repeatedly adjust the preload
by tightening the transfer gear nut 5 to 10 degrees at a
time until the standard value is obtained.
(d) If the preload is insufficient, even though the tightening
torque of the transfer gear nut exceeds the maximum of
the standard value, loosen the transfer gear nut and apply
gear oil SAE 90 (GL-5) to the transfer gear nut and the
screw thread and the base of the driven pinion. And then
repeat the preceding operation. If the tightening torque is
smaller than the standard, replace the transfer pinion
bearing spacer with a new one and adjust it.
SST 09326-2001 1, 09556-16030
Torque: 378 NVm (3,855 kgfVcm, 279 ftVlbf)
51. INSTALL RING GEAR
(a) Completely remove grease and moisture on the contact
surfaces of the ring gear and the transfer ring gear mount-
ing case.
(b) Heat the ring gear in boiling water from 90 to 100C (194
to 212F).
(c) Carefully take the ring gear out of the boiling water.
