BEFORE BEGINNING TEST
During tests with a brake tester or chassis dynamometer,
such as braking force tests or speedometer tests, if only the
front or the rear wheels are to be rotated, it is necessary to
first set the center differential control switch to OFF (Hydrau-
lic multiplate clutch control is released), then set the Mode
Select Lever on the automatic transaxle to the FREE (Nor-
mal) Mode or to the LOCK
Mode depending on the type of test being performed.

ON±VEHICLE WHEEL BALANCING
NOTICE:
1. When doing on±vehicle wheel balancing on a fulltime 4WD
vehicle, to prevent the wheels from rotating at different
speeds or in different directions from each other (which
could lead to damage to the center differential or trans-
axle gears), always be sure to observe the following pre-
cautions:
(1) A11 four wheels should be jacked up, completely clear
of the ground.
(2) The wheels should be driven by both the engine and
the wheel balancer.
(3) The center differential control switch should be in the
OFF condition.
(4) The mode select lever on the transaxle should be in
the LOCK position.
(5) The parking brake lever should be fully released.
(6) None of the brakes should be allowed to drag.
2. Avoid sudden acceleration, deceleration and braking.
3. Carry out the wheel balancing with the transmission in D
range.
1. SET CENTER DIFFERENTIAL CONTROL SWITCH TO
OFF
(1) Check that the center differential control indicator light
goes off.
(2) Further check that hydraulic multiplate clutch control of
the center differential is in OFF condition.

± INTRODUCTIONPrecautions When Servicing Full±Time 4WD VehiclesIN±25

A pressure feeding lubrication system has been adopted to supply oil to the moving parts of this engine.
The lubrication system consists of an oil pan, oil pump, oil filter and other external parts which supply oil
to the moving parts in the engine block The oil circuit is shown in the illustration at the top of the pre-
vious page. Oil from the oil pan is pumped up by the oil pump. After it passes through the oil filter, it is
fed through the various oil holes in the crankshaft and cylinder block. After passing through the cylinder
block and performing its lubricating function, the oil is returned by gravity to the oil pan. A dipstick on the
center left side of the cylinder block is provided to check the oil level.
OIL PUMP
The oil pump pumps up oil from the oil pan and sends it under pressure to the various parts of the en-
gine.
An oil strainer is mounted in front of the inlet to the oil pump. The oil pump itself is a trochoid±type
pump, inside of which is a drive rotor and a driven rotor. 'When the drive rotor rotates, the driven rotor
rotates in the same direction, and since the axis of the driven rotor shaft is different from the center of
the driven rotor, the space between the two rotors is changed as they rotate. Oil is drawn in when the
space is wide and is discharged when the space in narrow.
OIL PRESSURE REGULATOR (RELIEF VALVE)
At high engine speeds, the engine oil supplied by the oil pump exceeds the capacity of the engine to
utilize it.
For that reason, the oil pressure regulator works to prevent an oversupply of oil. During normal oil sup-
ply, a coil spring and valve keep the by±pass closed, but when too much oil is being fed, the pressure
become extremely high, overpowering the force of the spring and opening the valves. This allows the
excess oil to flow through the valve and return to the oil pan.
OIL FILTER
The oil filter is a full flow type filter with a built±in paper filter element, Particles of metal from wear, air-
born dirt, carbon and other impurities can get in the oil during use and could cause accelerated wear or
seizing if allowed to circulate through the engine. The oil filter, integrated into the oil line, removes these
impurities as the oil passes through it. The filter is mounted outside the engine to simplify replacement of
the filter element.
A relief valve is also included ahead of the filter element to relieve the high oil pressure in case the filter
element becomes clogged with impurities. The relief valve opens when the oil pressure overpowers the
force of the spring. Oil passing through the relief valve by±passes the oil filter and flows directly into the
main oil hole in the engine.

1344, LOCTITE 242 or equivalent
8. START ENGINE AND CHECK FOR LEAKS
OIL PRESSURE CHECK
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring
or thinning.
If the quality is poor, replace the oil.
Use API grade SG multigrade, fuel± efficient and recom-
mended viscosity oil.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ºLº and ºFº marks on the
dipstick.
If low, check for the leakage and add oil up to ºFº mark

REPLACEMENT OF ENGINE OIL
AND OIL FILTER
NOTICE:
wProlonged and repeated contact with mineral oil will re-
sult in the removal of natural¿¿ts from the skin, leading
to dryness, irritation and dermatitis. In addition, used en-
gine oil contains potentially harmful contaminants
which may cause skin cancer.
wCare should be taken, therefore, when changing engine
oil, to minimize the frequency and length of time your
skin is exposed to used engine oil. Protective clothing
and gloves, that cannot be penetrated by oil, should be
worn. The skin should be thoroughly washed with soap
and water, or use waterless hand cleaner, to remove any
used engine oil. Do not use gasoline, thinners, or sol-
vents.
wIn order to preserve the environment, used oil must be
disposed of only at designated disposal sites.
1. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug, and drain the oil into a container.
2. REPLACE OIL FILTER
(a) Using SST, remove the oil filter.
