3B-15 Differential:
Breather Rubber Case
Inspect the breather rubber case (1) for wear or damage.
If any defects are found, replace the breather rubber
case with a new one.
Front Drive (Differential) Gear
Inspect the front drive (Differential) gear for damage.
Inspect the front drive (Differential) gear bearings for
abnormal noise and smooth rotation. If any defects are
found, replace defective parts.
Front Drive (Differential) Gear Shim Inspection
and Selection (LT-A400F, LT-F400F)
B827H13206009
Refer to “Front Drive (Differential) Assembly Removal
and Installation (LT-A400F, LT-F400F) (Page 3B-4)” and
“Front Drive (Differential) Assembly Disassembly and
Assembly (LT-A400F, LT-F400F) (Page 3B-5)”.
Backlash
1) Remove the front drive (differential) gear assembly
from the frame.
2) Make sure that the front drive (differential) case
cover bolts are tightened to the specified torque.
Tightening torque
Front drive (differential) gear case cover bolt
(a): 23 N·m (2.3 kgf-m, 16.5 lb-ft)
3) Remove the gear oil filler plug and measure the
backlash of the differential ring gear using a
horizontal type dial gauge (1) and drive shaft (2) as
shown in the figure.
4) Take backlash readings at three places while turning
the front drive (differential) gear slightly in each
direction and securely holding the pinion gear. Read
the total backlash on the dial gauge.
