8. Clutch Fluid
A: REPLACEMENT
CAUTION:
The FMVSS No. 116, fresh DOT3 or 4 brake fluid
must be used.
Cover bleeder with waste cloth, when loosening it,
to prevent clutch fluid from being splashed over sur-
rounding parts.
Avoid mixing different brands of clutch fluid to pre-
vent degrading the quality of the fluid.
Be careful not to allow dirt or dust to get into the
reservoir tank.
NOTE:
During bleeding operation, keep the clutch reserve tank
filled with clutch fluid to eliminate entry of air.
Clutch pedal operating must be very slow.
For convenience and safety, it is advisable to have two
man working.
The amount of clutch fluid required is approximately 70
m
(2.4 US fl oz, 2.5 Imp fl oz) for total clutch system.
1) Either jack-up vehicle and place a safety stand under it,
or lift-up vehicle.
2) Remove both front and rear wheels.
3) Draw out the clutch fluid from reserve tank with syringe.
4) Refill reservoir tank with recommended clutch fluid.
Recommended clutch fluid:
FMVSS No. 116, fresh DOT3 or 4 brake fluid
5) Bleed air from oil line with the help of a co-worker.

Symptom and possible cause Remedy
4. Broken differential (case, gear, bearing, etc.)
Abnormal noise will develop and finally it will become impossible to continue to run due to broken pieces obstructing the gear
revolution.
(a) Insufficient or improper oil Disassemble differential and replace broken components and
at the same time check other components for any trouble,
and replace if necessary.
(b) Use of vehicle under severe conditions such as excessive
load and improper use of clutchReadjust bearing preload and backlash and face contact of
gears.
(c) Improper adjustment of taper roller bearing Adjust.
(d) Improper adjustment of drive pinion and hypoid driven
gearAdjust.
(e) Excessive backlash due to worn differential side gear,
washer or differential pinionAdd recommended oil to specified level. Do not use vehicle
under severe operating conditions.
(f) Loose hypoid driven gear clamping bolts Tighten.
5. Differential and hypoid gear noises
Troubles of the differential and hypoid gear always appear as noise problems. Therefore noise is the first indication of the
trouble. However noises from the engine, muffler, tire, exhaust gas, bearing, body, etc. are easily mistaken for the differential
noise. Pay special attention to the hypoid gear noise because it is easily confused with other gear noises. There are the
following four kinds of noises.
(1) Gear noise when driving: If noise increases as vehicle speed increases it may be due to insufficient gear oil, incorrect
gear engagement, damaged gears, etc.
(2) Gear noise when coasting: Damaged gears due to maladjusted bearings and incorrect shim adjustment
(3) Bearing noise when driving or when coasting: Cracked, broken or damaged bearings
(4) Noise which mainly occurs when turning: Unusual noise from differential side gear, differential pinion, differential pinion
shaft, etc.
(a) Insufficient oil Lubricate.
(b) Improper adjustment of hypoid driven gear and drive
pinionCheck tooth contact.
(c) Worn teeth of hypoid driven gear and drive pinion Replace as a set.
Readjust bearing preload.
(d) Loose roller bearing Readjust hypoid driven gear to drive pinion backlash and
check tooth contact.
(e) Distorted hypoid driven gear or differential case Replace.
(f) Worn washer and differential pinion shaft Replace.

A: INSPECTION
1. ATF LEVEL
1) Raise ATF temperature to 60 to 80°C (140 to 176°F)
from 40 to 60°C (104 to 140°F) (when cold) by driving a
distance of 5 to 10 km (3 to 6 miles).
NOTE:
The level of ATF varies with fluid temperature. Pay atten-
tion to the fluid temperature when checking oil level.
2) Make sure the vehicle is level. After selecting all posi-
tions (P, R, N, D, 3, 2, 1), set the selector leveler in“P”
range. Measure fluid level with the engine idling.
NOTE:
After running, idle the engine for one or two minutes before
measurement.
3) If the fluid level is below the center between upper and
lower marks, add the recommended ATF until the fluid level
is found within the specified range (above the center
between upper and lower marks). When the transmission
is hot, the level should be above the center of upper and
lower marks, and when it is cold, the level should be found
below the center of these two marks.
CAUTION:
Use care not to exceed the upper limit level.
ATF level varies with temperature. Remember that
the addition of fluid to the upper limit mark when the
transmission is cold will result in the overfilling of
fluid.
4) Fluid temperature rising speed
By idling the engine
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 25 minutes

Time for temperature rise to 30°C (86°F) with atmo-
spheric temperature of 0°C (32°F): Approx. 8 minutes
By running the vehicle
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 10 minutes
5) Method for checking fluid level upon delivery or at peri-
odic inspection
Check fluid level after a warm-up run of approx. 10 min-
utes. During the warm-up period, the automatic transmis-
sion functions can also be checked.
