 Tighten mounting bolts in the order as described below when installing front final drive assembly: side of gear carrier (1), upper
side of gear carrier (2), part of ca rrier cover (3), lower part of gear
carrier (4).
CAUTION:
Align the mating faces of gear car rier and oil pan for installa-
tion.
 When installing breather hoses (1) and tube (2), refer to the figure. CAUTION:
Make sure there are no pinched or restricted areas on the
breather hose caused by bending or winding when installing
it.
- Make sure the paint mark facing up ( ).
- Securely install the hose until it seats the rounded portion of the
tube ( ).
- Install breather connector as shown in the figure.
- Seat the breather tube bracket end (A) to the machined face (B) of gear carrier boss.
 When oil leaks while removing final drive assembly, check oil level after the installation. Refer to FFD-8, "

 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".

Oc. After warming up engine, make sure there is no leakage of engine oil with running engine.
Changing Engine OilINFOID:0000000001325814
WARNING:
 Be careful not to get burn yourself, as engine oil may be hot.
 Prolonged and repeated contact with used engine
oil may cause skin cancer. Try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thorough ly with soap or hand cleaner as
soon as possible.
1. Remove front engine undercover with power tool.
2. Warm up the engine, and check for engine oil leakage from engine components. Refer to LU-5, "
Inspec-
tion".
3. Stop the engine and wait for 10 minutes.
4. Loosen oil filler cap and then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer. Refer to EM-30, "

Refer to MA-9, "
Fluids and Lubricants".
Engine oil capacity (Approximate):
Unit: (US qt, lmp qt)
CAUTION:
 When filling engine oil, do not pull out oil level gauge.
 The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
