CYLINDER BLOCK
The cylinder block is made of cast aluminum alloy and
has 4 cylinders arranged “In-Line”. A cylindrical cast
iron sleeve is installed in each cylinder.
CRANKSHAFT AND MAIN
BEARINGS
A monoblock casting crankshaft is supported by
5 main bearings which are of precision insert type.
Four crank pins on the crankshaft are positioned 180
apart.
PISTONS, RINGS, PISTON PINS AND
CONNECTING RODS
The piston is cast aluminum alloy, and has two com-
pression rings and one oil ring.
Among two compression rings (top and 2nd rings),
the outer surface of the top ring is treated with hard
chromium for improvement in abrasion resistance.
The oil ring consists of two rails and one spacer. The
piston pin is offset 0.5 mm towards the major thrust
side.This allows a gradual change in thrust pressure
against the cylinder wall as the piston travels its path.
Pins, made of chromium steel, have a floating fit in the
pistons and in the connecting rods. The connecting
rods are made of forged steel, and the rod bearings
are of precision insert type.
CYLINDER HEAD AND VALVE TRAIN
The cylinder head is made of aluminum casting. The
supporting part of the camshaft is an independent cap
type. The combustion chamber has 4 valves and uses
the center plug type pent roof shape for higher intake
and exhaust efficiency.
As the intake side rocker arm is end pivot type, it
swings according to the camshaft movement to open
and close the intake valve.
On the other hand, the exhaust side rocker arm is see-
saw type. It swings with the rocker arm shaft as its
supporting point and according to the camshaft
movement to open and close the exhaust valve.

OIL PRESSURE CHECK
NOTE:
Prior to checking oil pressure, check the following items.

Oil level in oil pan.
If oil level is low, add oil up to Full level mark on oil level
gauge.

Oil quality.
If oil is discolored, or deteriorated, change it.
For particular oil to be used, refer to the table in Section 0B.

Oil leaks.
If leak is found, repair it.
1) Remove oil pressure switch (1) from cylinder block.
2) Install special tool (Oil pressure gauge) to vacated threaded
hole.

sure oil pressure.
Oil pressure specification:
360 – 440 kPa (3.6 – 4.4 kg / cm
2, 51.2 – 62.6 psi) at 4,000 r / min
(rpm)
5) Stop engine and remove oil pressure gauge.

AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC) 7B-3
GENERAL DESCRIPTION
The automatic transmission consists of the hydraulic torque converter, electronically controlled 3-speed automatic
transmission, countershaft and differential.
The transmission consists of 2 planetary gears, 2 disk clutches, 1 band brake, 1 disk brake and 1 one-way clutch.
Its operation is controlled by selecting a position from 6 positions (P, R, N, D, 2 and L ranges) manually by means
of the selector lever installed on the compartment floor.
In the D or 2 range, the gear ratio is changed for the 1st, 2nd or 3rd speed (D range only) automatically by engine
control module (electronic control).
For the automatic transmission fluid, DEXRON

or its equivalent must be used. Lubrication
in the automatic transmission is provided by the oil pump which is operated by the engine revolution. Therefore,
the engine should not be stopped even during coasting to obtain proper lubrication.
When it becomes necessary to be towed, front wheels must be raised so as not to roll them.

TRANSMISSION RANGE SENSOR (SHIFT SWITCH)
Being linked with the selector lever, this sensor changes selector
lever positions into electric signals and send them to the engine
control module. The contact points of this sensor for P and N ranges
are also connected with the starting motor circuit.
So when the selector lever is shifted to the P or N range position,
the contact points for P or N range are connected and cause the
starting motor to operate by turning the starter switch ON.
When the selector lever is in any other position than P and N
ranges, the sensor remains OFF and therefore the starting motor
cannot be operated, that is, the engine cannot be started.
Also, as its contact point for R range is connected with the backup
lamp circuit, only when the selector lever is shifted to R range, the
contact point contacts to light the backup lamp.
DIRECT CLUTCH AND 2ND BRAKE SOLENOID
VALVES
These solenoid valves are mounted on the valve body. They are
turned ON and OFF by the signals from the engine control module
and actuate each shift valve (1 – 2 and 2 – 3 valves) so as to control
transmission gear shift.
Shift solenoid-B (2nd brake solenoid valve) operates 1 – 2 shift
valve, and shift solenoid-A (direct clutch solenoid valve) does 2 –
3 shift valve.
