DRIVE PINION
CAUTION:
• Never reuse lock nut.
• If specified preload torque is exceeded, replace the collapsible spacer and tighten again. Never
loosen the pinion lock nut for further preload torque adjustment.
11. Apply multi-purpose grease lightly and evenly onto an O-ring, and install it to the pinion sleeve.
CAUTION:
Never reuse O-ring.
12. Assemble the selected pinion sleeve shim.
13. Install the pinion sleeve assembly, and apply anti-corrosive oil onto thread and seats on the mounting
bolts. Tighten to the specified torque. Refer to
14. Check backlash, tooth contact, total preload and companion flange runout. Refer to
CAUTION:
Measure the total preload without the adapter case oil seal.
Adjustment
INFOID:0000000005514225
BACKLASH
1.
Install a bolt to the companion flange.
2.
Fit a dial indicator onto the bolt.
3.
Measure the circumference backlash of the companion flange,
and Check that it satisfies the standard below.
• If measured value is out of the specification, disassemble it to
check and adjust each part.
TOOTH CONTACT
1.
Remove the pinion sleeve assembly. Refer to
.
2.
Apply red lead to the drive gear.
CAUTION:
Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on the drive gear.
3.
Install the pinion sleeve shims and pinion sleeve assembly.
Refer to
.
4.
Remove the plug on the upper side of the transfer case.
When installing plug, apply sealant on screw part, and tighten it
at the specified torque. Refer to
Use Genuine Silicone RTV or equivalent. Refer to
"Recommended Chemical Products and Sealants"

5.
Rotate the companion flange back and forth several times, and
check the drive pinion gear to drive gear tooth contact by view-
ing from the plug hole.
6.
If tooth contact is poorly adjusted, adjust pinion height (dimen-
sion X) in the following manner.
