NOTE:
The following procedures explain how to disassemble the engine with the engine stand fastened to the bell
housing. Some steps may be different if using a different type of engine stand.
1. Install engine to engine stand:
a. On (M/T models), remove flywheel.
• Secure flywheel using suitable tool and remove bolts.
CAUTION:
• Do not disassemble flywheel.
• Do not place flywheel with signal plate facing down.
• When handling signal plate, take care not to damage or scratch it.
• Handle signal plate in a manner that prevents it from becoming magnetized.
b. On (CVT models), remove driveplate. • Secure driveplate using suitable tool and remove bolts.
CAUTION:
• Do not disassemble flywheel.
• Do not place flywheel or drive plat e with signal plate facing down.
• When handling signal plate, take care not to damage or scratch it.
• Handle signal plate in a manner that prevents it from becoming magnetized.
c. Lift the engine with a hoist to install it onto a widely used engine stand. CAUTION:
• Use the engine stand that has a load capacity approximately 150 kg (331 lb) or more large
enough for supporting the engine weight.
• If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the poten- tial risk of overturning stand.
- Intake manifold. Refer to EM-28, "
Exploded View".
- Exhaust manifold. Refer to EM-31, "
Removal and Installation".
- Rocker cover. Refer to EM-48, "
Exploded View".
CAUTION:
Before removing the hanging chains, check the engine stand is stable and there is no risk of over-
turning.
NOTE:
The figure shows an example of widely used engine stand (A)
that can support the mating surface of transaxle with flywheel
removed.
2. Drain engine oil. Refer to LU-8, "
Draining".
CAUTION:
• Be sure to clean drain plug and in stall with new drain plug washer.
• Do not reuse drain plug washer. Tool number : KV11105210 (J-44716)

3. Install oil jets.
4. Install main bearings and thrust bearings:
a. Remove dust, dirt, and engine oil on the bear
ing mating surfaces of cylinder block.
b. Install thrust bearings to the both sides of the No. 3 journal hous- ing (B) on cylinder block.
• Install thrust bearings with the oil groove (A) facing crankshaftarm (outside).
c. Install the main bearings paying attention to the direction. • Before installing main bearings, apply new engine oil to the bearing surface (inside). Do not apply
engine oil to the back surface, but thoroughly clean it.
• When installing, align main bearing to the center position of cylinder block and main bearing cap.
• Ensure the oil holes on cylinder block and oil holes (A) on the
main bearings (1) are aligned.
NOTE:
For assembly, the center position can be visually identified.
• To install the main bearing, obtain a proper fit. Do not allow the main bearing to lie off the cylinder block chamfer.
• To install the main bearing, obtain a proper fit. Do not allow the
main bearing to lie off bearing cap chamfer.
5. Install signal plate to crankshaft if removed.
a. Set the signal plate (1) with the flange facing toward the counter- weight side (engine front side) to the crankshaft rear surface.
b. After positioning crankshaft and signal plate with positioning dowel pin, tighten bolt.
NOTE:
Dowel pin of crankshaft and signal plate is provided as a set for
each.
c. Remove dowel pin. CAUTION:
Be sure to remove dowel pin.
6. Install crankshaft to cylinder block. • While turning crankshaft by hand, check that it turns smoothly.
CAUTION:
Do not install rear oil seal at this time.
7. Install main bearing caps.

< SYSTEM DESCRIPTION >[HR16DE]
COMPONENT PARTS
ECM receives the signals as shown in the figure.
Clutch Pedal Position SwitchINFOID:0000000012431275
When the clutch pedal is depressed, the clutch pedal pos
ition switch turns OFF and the clutch pedal position
switch signal is sent to the ECM. The ECM judges t he clutch pedal conditions via the signal (ON or OFF).
Cooling FanINFOID:0000000012431276
Cooling fan operates at low and high speed when the current flows in the cooling fan motor.
Refer to EC-38, "
COOLING FAN CONTROL : System Description" for cooling fan operation.
Crankshaft Position SensorINFOID:0000000012431277
The crankshaft position sensor is located on the cylinder block rear
housing facing the gear teeth (cogs) of the signal plate at end of the
crankshaft. It detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
ECM receives the signals as shown in the figure.
ECMINFOID:0000000012431278
The ECM consists of a microcomputer and connectors for signal
input and output and for power supply. The ECM controls the engine.

Electric Throttle Control ActuatorINFOID:0000000012431279
Electric throttle control actuator consists of throttle control mo
tor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feed-
back to the ECM to control the throttle valve in response to driving conditions via the throttle control motor.
Engine Coolant Temperature SensorINFOID:0000000012431280
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the change in temperature. The electrical resistance of the ther-
mistor decreases as temperature increases.
*: These data are reference values and are measured between ECM terminals.
Engine Oil Pressure SensorINFOID:0000000012431281
The engine oil pressure (EOP) sensor is detects engine oil pressure
and transmits a voltage signal to the ECM.
Engine Oil Temperature SensorINFOID:0000000012431282
The engine oil temperature sensor is used to detect the engine oil
temperature. The sensor modifies a voltage signal from the ECM.
The modified signal returns to the ECM as the engine oil tempera-
ture input. The sensor uses a thermistor which is sensitive to the
change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.
