Transfer Bevel Pinion Shim Adjustment
Transfer Bevel Pinion Shim AdjustmentTo mesh bevel gears correctly, it is prerequired to install bevel pinion to transfer output retainer properly by using adjusting shim (bevel pinion shim) as described on following steps.
1. Install pinion shaft FR taper roller bearing (1) to bevel pinion dummy (special tools).
Special Tool
(A): 09922-76140
(B): 09922-76420
2. Install bevel pinion dummy (1), pinion shaft RR taper roller bearing (2) and special tools to transfer output retainer (3).
Special Tool
(A): 09922-76140
(B): 09922-76420
(C): 09922-76310
(D): 09922-76320
(E): 09922-76340
(F): 09922-76150
NOTE: This installation requires no spacer or oil seal.
3. Tighten bevel pinion nut (special tool) so that specified bearing preload is obtained.
NOTE: Before taking measurement, check for rotation by hand more than 15 revolutions.
Tightening torque
Rotational torque of bevel pinion shaft (Bearing preload) 0.50 - 1.50 Nm (5.0 - 15.0 kgf-cm, 0.35 - 1.10 ft. lbs.)
4. Measure height "b" in figure by using vernier caliper.
Calculate "c" by using measured value.
Distance "c" = Height "b" - Height "a" 40 mm (1.575 inch)
5. Obtain adjusting shim thickness by the following equation.
Necessary shim thickness "f" = Distance "c" -
Distance "e" 79.25 mm (3.120 inch)
+
Distance "d" 61.2 mm (2.409 inch)
6. Select adjusting shim closest to calculated value from among the following available sizes.
Available bevel pinion shim thickness
0.30, 0.60, 0.63, 0.66, 0.69, 0.72, 0.75, 0.78, 0.81, 0.84 and 0.87 mm (0.012, 0.024, 0.025, 0.026, 0.027, 0.028, 0.030, 0.031, 0.032, 0.033 and 0.034 inch)
