5. VALVE SPRING
1) Check the valve springs for damage, free length,
and tension. Replace the valve spring if it is not
within the standard value presented in the table.
2) To measure the squareness of the valve spring,
stand the spring on a surface plate and measure its
deflection at the top of spring using a try square.
6. INTAKE AND EXHAUST VALVE OIL
SEAL
In the following case, pinch and remove the oil seal
from valve using pliers, and then replace it with a
new one.
•When the lip is damaged.
•When the spring is out of the specified position.
•When readjusting the surfaces of intake valve
and valve sheet.
•When replacing the intake valve guide.
1) Set the cylinder head on ST1.
2) Press-fit the oil seal to the specified dimension
indicated in the figure using ST2.

ST2 499585500 VALVE OIL SEAL GUIDE
NOTE:
•Apply engine oil to oil seal before press-fitting.
•When press-fitting the oil seal, do not use a ham-
mer or strike in.
7. VALVE LIFTER
1) Check the valve lifter visually.
2) Measure the outer diameter of valve lifter.
Outer diameter:
32.959 — 32.975 mm (1.2976 — 1.2982 in)
3) Measure the inner diameter of valve lifter hole of
cylinder head.
Inner diameter:
32.994 — 33.016 mm (1.2990 — 1.2998 in)
NOTE:
If difference between outer diameter of valve lifter
and inner diameter of valve lifter hole is out of the
standard or offset wearing is emitted, replace the
cylinder head.

Front & Rear Differential Oil
PERIODIC MAINTENANCE SERVICES
12.Front & Rear Differential Oil
A: REPLACEMENT
1. FRONT DIFFERENTIAL
1) Drain the differential gear oil by removing drain
plug using TORX® BIT T70.
NOTE:
•Before starting work, cool off the differential gear
oil well.
•If front differential gear oil adheres to the exhaust
pipe, wipe it off completely.
2) Replace the gasket with new one, and then tight-
en the drain plug to specified torque.
Tightening torque:
70 N·m (7.1 kgf-m, 51.6 ft-lb)
3) Fill differential gear oil through the oil level
gauge hole up to the upper point of level gauge.
Recommended gear oil:
Refer to “RM” section. CANTS, RECOMMENDED MATERIALS, Rec-
ommended Materials.>
NOTE:
Each oil manufacturer has its base oil and addi-
tives. Thus, do not mix two or more brands.
Gear oil capacity:
1.3 — 1.5 2 (1 . 4 — 1 .6 U S q t , 1 . 1 — 1 .3 lmp q t)
2. REAR DIFFERENTIAL
1) Drain the oil by removing drain plug.
2) Remove the filler plug for quick draining oil.
3) Tighten the drain plug after draining oil and re-
placing with a new gasket.
Tightening torque:
29 N·m (3.1 kgf-m, 21.4 ft-lb)
4) Pour oil to the bottom end of filler plug hole.
Recommended gear oil:
Refer to “RM” section. CANTS, RECOMMENDED MATERIALS, Rec-
ommended Materials.>
Oil capacity:
0.8 2 (0.8 US qt, 0.7 lmp qt)
NOTE:
Each oil manufacturer has its base oil and addi-
tives. Thus, do not mix two or more brands.
5) Replace the gasket with a new one and tighten
the filler plug.

3. Differential Gear Oil
A: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the collector cover.
3) Remove the oil level gauge and wipe it clean.
4) Reinsert the level gauge all the way. Make sure
the level gauge is inserted correctly and in the
proper orientation.
5) Remove the oil level gauge again, and check the
level of differential gear oil. If the differential gear oil
level is below “L” line, add oil to bring the level up to
“F” line.
NOTE:
To prevent overfilling the differential gear oil, do not
add oil above the “F” line.
B: REPLACEMENT
1) Lift-up the vehicle.
2) Remove the differential gear oil drain plug using
TORX® BIT T70, and then drain differential gear
oil.
CAUTION:
•Immediately after the vehicle has been run-
ning or after idling for a long time, the differen-
tial gear oil will be hot. Be careful not to burn
yourself.
•Be careful not to spill differential gear oil on
the exhaust pipe to prevent it from emitting
smoke or causing a fire. If differential gear oil is
spilled on the exhaust pipe, wipe it off com-
pletely.
3) Tighten the differential gear oil drain plug using
TORX® BIT T70.
NOTE:
Use a new gasket.
Tightening torque:
70 N·m (7.1 kgf-m, 51.6 ft-lb)
4) Lower the vehicle.
5) Pour gear oil into the gauge hole.
Recommended gear oil:
