4.2. INSPECTION
Before and after disassembly, inspect each part
for the items mentioned below. Parts which
deviate from the specified values should be
replaced.
-Wash clean all disassembled parts and check
them for wear, damage, deformation, Burning ,
etc. Defective
parts should be corrected or replaced.
-As the drive pinion and the ring gear make a pair,
they should be replaced together even if only one
is found to be defective.
-Backlash between the drive pinion and the ring
gear
Backlash 0.1-0.25 mm
(0.004-0.009 in)
-Backlash between the diff-pinion and the dif-side gear.
Backlash 0.13-0.2 mm
(0.003-0.008 in)
-When the backlash exceeds 0.5mm, also inspect the
thrust collar for wear, defective collars should be
replaced.
-Disengaging the resistance of PTO shifters.
Standard Value 18-22 Kgf (40-49lbs)
Usable limit 17 Kgf (38 lbs)
* Measured at the shifter
4.3. REASSEMBLY
Reassemble the parts in reverse order of
disassembly, following these instructions.
(1) Ring gear, Drive pinion, and related parts.
a. Apply oil to the drive pinion and related parts
ahead of time. Then install them and tighten the
assembly to the specified torque.
Tightening torque
(M40x1.5pitch)
1.4 Kgf.m (9.36 ft.lbs)
(1) Drive pinion
(2) Tapered roller bearing
(3) Drive pinion metal
(4) Tapered roller bearing
(5) Nut (M40X1.5)
b.Be sure that the starting torque of the
drive pinion meets the specified level.
Starting torque 0.11-0.13 Kgf.m
(0.576 ~ 0.792 ft.lbs)
c. After the starting torque has been adjusted
to the specified level, crimp the lock of the
nut at one point as illustrated.
d. Tighten the drive pinion metal by
providing it with the same shimming
thickness that it had when it was
disassembled.
