14. MEASURE TOTAL PRELOAD
Using SST (or a 36 mm deep socket) and a torque wrench,
measure the total preload.
SST 09229±55010
Total preload (In addition to drive pinion preload):
New and Reused bearing
2JZ±GTE M/T
0.4±0.6 NVm (4±6 kgfVcm, 3.5±5.2 in.Vlbf)
Except 2JZ±GTE M/T
0.5±0.8 NVm (5±8 kgfVcm, 4.3±6.9 in.Vlbf)
If the measured preload is less than specification, replace the
washer of the ring gear's tooth surface side with a thicker
one.
If the preload is greater than the specification, replace the
washer of the ring gear's tooth surface side with thinner one.
HINT: Changing the washer thickness by 0.02 mm (0.0008
in.) will change the total preload by approx. 0.1 NVm (1 kgfVcm,
0.9 in.Vlbf).
15. INSPECT TOOTH CONTACT PATTERN
(a) Coat 3 or 4 teeth at 3 different positions on the ring gear with
red lead.
(b) Hold the companion flange firmly and rotate the ring gear in
both directions.
(c) Inspect the tooth contact pattern.
