REAR DIFFERENTIAL 7F-15
15) Install companion flange (3) to drive bevel pinion and tighten
drive bevel pinion nut gradually with special tool, set preload
of bearing to specification.
Tightening torque
Drive bevel pinion nut (reference)
70 – 250 N·m (7.0 – 25.0 kg-m, 51.0 – 181.0 lb-ft)
Drive bevel pinion bearing preload
0.5 – 1.3 N·m (5.0 – 13.0 kg-cm, 0.35 – 0.90 lb-ft)
Special tool
(A): 09930-40113
Differential assembly
1) Place differential gear case assembly to differential carrier,
push differential case to left side as shown in figure.
Then measure clearance “a” between side bearing and dif-
ferential carrier by using thickness gauge.
Select shims closest to measured value.
Available shim thickness
0.1, 0.3, 0.5 and 0.7 mm (0.0039, 0.0117, 0.0197 and 0.0276
in.)
NOTE:
• Before taking measurement, check for smooth rotation
by hand.
• Drive bevel pinion bearing preload is adjusted by tight-
ening drive bevel pinon nut to deform spacer.
Therefore, be sure to use a new spacer for adjustment
and tighten drive bevel pinion nut step by step and
check for starting torque (preload) as often as tighten-
ing to prevent over crushing of spacer.
If exceeds specification given below during adjust-
ment, replace spacer and repeat preload adjustment
procedure. Attempt to decrease starting torque (pre-
load) by loosening drive bevel pinon nut will not do.
• For measuring drive bevel pinion bearing preload,
turning drive bevel pinion at about 50 rpm is required.
