7) Measure preload of pinion bearing with spring balance (1) or
torque wrench (2) and check composite preload of pinion
bearing and side bearing.
Composite preload of pinion bearing and side bearing
: 1.1 – 2.0 N·m (11.0 – 20.0 kg-cm, 9.5 – 17.4 lb-in.)
Spring measure reading with special tool
: 19.5 – 35.5 N (1.95 – 3.55 kg, 4.30 – 7.83 lb)
Special tool
(D) : 09922-76560
8) Torque bearing cap bolts (2) to specification and install bear-
ing lock plates.
Tightening torque
Lock plate bolt (b) : 12 N·m (1.2 kg-m, 9.0 lb-ft)
Bearing cap bolt (c) : 85 N·m (8.5 kg-m, 61.5 lb-ft)
9) As final step, check gear tooth contact as follows.
a) After cleaning 10 drive bevel gear teeth, paint them with
gear marking compound evenly by using brush or sponge
etc.
b) Turn gear to bring its painted part in mesh with drive bevel
pinion and turn it back and forth by hand to repeat their con-
tact.
c) Bring painted part up and check contact pattern, referring
to following chart. If contact pattern is not normal, readjust
or replace as necessary according to instruction in chart. NOTE:
Before taking measurement with spring balance (1) or
torque wrench (2), check for smooth rotation by hand.
On measuring preload, rotate the drive bevel pinion
about 1 rotation per 2 seconds.
3. Universal joint flange
4. Socket with adapter
1. Lock plate bolt
NOTE:
Be careful not to turn drive bevel gear more than one full
revolution, for it will hinder accurate check.
1. Brush
“A”: Paint gear marking compound evenly
