Measurement of Compression Pressure
1. Warm up engine and switch off the ignition switch.
2. Remove glow plate and glow plugs.
3. Fit compression gauge adapter to cylinder head.
Compression gauge adapter:
:15-20N×m
(1.5 - 2.0 kg-m, 11 - 14 ft-lb)
4. Ensure the ignition switch is in the ªLOCKº position and discon-
nect harness connector (gray colored) from injection pump.
5. Crank engine, then read gauge indication.
IAlways use a fully-charged battery to obtain specified
engine revolution.
IEngine compression measurement should be made as
quickly as possible.
Compression pressure:
Unit: kPa (bar, kg/cm2, psi)/200 rpm
Standard 2,942 (29.4, 30, 427)
Minimum 2,452 (24.5, 25, 356)
Differential limit between cylinders 294 (2.9, 3, 43)
6. If cylinder compression in one or more cylinders is low, pour a
small amount of engine oil into cylinders through the glow holes
and retest compression.
IIf adding oil helps the compression pressure, piston rings
may be worn or damaged.
IIf pressure stays low, valve may be sticking or seating
incorrectly.
IIf cylinder compression in any two adjacent cylinders is
low, and if adding oil does not help the compression, there
is leakage past the gasket surface.
Leakage past the cylinder gasket can result in oil and water
becoming mixed in the engine block cooling and lubrica-
tion chambers.

qB
Was the vehicle moved in one
direction after the vehicle was
driven in another direction when
the transfer lever was in the ª4Hº
or the ª4Lº position and then
returned to the ª2Hº position?
No
EYe s
Auto-hub gears will disengage
with a resultant noise (clicking). If
the distance the vehicle is moved
in the opposite direction is short
[less than1m(3ft)] or if the rota-
tion angle of the left and right
wheels is not the same (as in
rounding a corner), gears on one
side will disengage (Fig.
).
Under this condition, a noise
(crushing, etc.) might occur while
driving in the ª2Hº position. If only
gears on one side are unlocked,
the locked drive shaft rotates at
the same speed as wheels;
however, the unlocked drive shaft
is made to rotate in the reverse
direction by the differential. This
forces by auto hub's slide gear to
lock in the reverse direction. As a
result, noise occurs.
If this happens, slowly move the
vehicle straight back approxi-
mately 2 to3m(7to10ft)with
the transfer lever in the ª2Hº posi-
tion to disengage the gears on the
other side.
Was the vehicle driven with the
transfer lever in the ª2Hº position
in extremely cold weather?
No
EYe s
In extremely cold weather (areas),
the viscosity of differential oil is
greater than in moderate weather.
When the auto hubs are unlocked
with the transfer lever set to the
ª2Hº position, one auto hub can
sometimes remain locked.
This causes noise during opera-
tion. Noise can also occur in the
auto hub when the front propeller
shaft is rotated due to the viscos-
ity resistance of the transfer fluid
(Fig.
).
In such a case, drive in the ª4Hº
position for approximately 10 min-
utes until the vehicle warms up,
and return the transfer lever to the
ª2Hº position to eliminate the
noise.
Disassemble and check the auto
hub.
