Final Gear Backlash Inspection and Shim
Adjustment
B827H13206019
Refer to “Final Gear Assembly Removal and Installation
(Page 3B-21)” and “Final Gear Assembly Disassembly
and Assembly (Page 3B-23)”.
Backlash
1) Install the shim(-s), final drive gear assembly and
new final drive gear bearing lock-nut.
2) Tighten the final drive gear bearing lock-nut to the
specified torque with the special tool.
NOTE
As this time, it is not necessary to bend the
bearing stopper collar.
Special tool
(A): 09924–41830 (Bearing retainer wrench)
Tightening torque
Final drive gear bearing lock-nut (a): 80 N·m (8.0
kgf-m, 58.0 lb-ft)
3) Install the left side shim(-s) and final driven gear.
Special tool
(A): 09900–20607 (Dial gauge (1/100 mm, 10
mm))
(B): 09900–20701 (Magnetic stand)
Final gear backlash
Standard: 0.02 – 0.06 mm (0.0008 – 0.0024 in)
(without gear cover specification)
Standard: 0.08 – 0.13 mm (0.0031 – 0.0051 in)
(Gear cover assembled specification)
4) Measure the backlash with the dial gauge, as shown.
Take backlash readings at several places while
turning the final drive gear shaft in each direction and
securely holding the final driven gear. If the backlash
is not within specification, the shim must be changed
and the backlash should be re-checked until the
backlash is within the specification. Check to the
table for the appropriate shim thickness.
NOTE
Adjust the backlash by referring to the table
and using the thickness of the removed
shims as a guide.
