 When connecting rod bearing cap is removed after being tightened
to the specified torque with connecting rod bearings installed, the
tip end of bearing must protrude. Refer to EM-242, "
Disassembly
and Assembly" for the tightening procedure.
 If the standard is not met, replace connecting rod bearings.
DRIVE PLATE
 Check drive plate and signal plate for deformation or cracks. CAUTION:
 Do not disassemble drive plate.
 Do not place drive plate with signal plate facing down.
 When handling signal plate, take care not to damage or scratch it.
 Handle signal plate in a manner that prevents it from becom-
ing magnetized.
 If anything is found, replace drive plate. Standard : There must be crush height.

 If the tooth contact is near the face (face contact), or near the heel (heel contact), thicken pinion height adjusting washers to move
drive pinion closer to drive gear.
Refer to FFD-39, "
Inspection and Adjustment".
 If the tooth contact is near the flank (flank contact), or near the toe
(toe contact), thin pinion height adjusting washers to move drive
pinion farther from drive gear.
Refer to FFD-39, "
Inspection and Adjustment".
Backlash
1. Remove carrier cover. Refer to "Differential Assembly".
2. Fit a dial indicator to the drive gear face to measure the back-
lash.
 If the backlash is outside of the specified value, change the thick- ness of side bearing adjusting washer.
Companion Flange Runout
1. Fit a dial indicator onto the companion flange face (inner side of the propeller shaft mounting bolt holes).
2. Rotate companion flange to check for runout.
3. Fit a test indicator to the inner side of companion flange (socket diameter).
4. Rotate companion flange to check for runout.
5. If the runout value is outside the runout limit, follow the procedure below to adjust.
a. Check for runout while changing the phase between companion flange and drive pinion by 90 ° step, and
search for the position where the runout is the minimum.

Backlash: 0.10 - 0.15 mm (0.0039 - 0.0059 in)
When the backlash is large:
Decrease side bearing adju sting washer thickness.
Refer to FFD-39, "
Inspection and Adjustment".
When the backlash is small: Increase side bearing adjust ing washer thickness. Re-
fer to FFD-39, "
Inspection and Adjustment".

Never drop drive pinion assembly.
6. Remove front oil seal.
7. Remove pinion front bearing inner race.
8. Remove drive pinion bearing adjusting washer and drive pinion adjusting washer.
9. Remove pinion rear bearing inner race and pinion height adjust- ing washer with replacer.
10. Tap pinion front/rear bearing outer races uniformly a brass rod or equivalent to removed.
CAUTION:
Be careful not to damage gear carrier.
INSPECTION AFTER DISASSEMBLY
Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.

Content Conditions and Measures
Hypoid gear  If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.
 If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive gear and drive pinion as a set.
Bearing  If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing
is observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear  If any cracks or damage on the surface of the tooth is found, replace.
 If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer  If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal  Whenever disassembled, replace.
 If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.
Differential case  If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange  If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the
companion flange is found, replace.
