Overview

Subject Scope

 This manual comprises procedures on engine

maintenance, and specific procedures fall into

5 basic operation steps:

I: dismantling/mounting; II disassembling

/mounting; III: resetting; IV inspection; V

adjustment.

 Simple operation may be completed by

inspecting the engine appearance, such as

dismantling/mounting of periphery parts,

parts cleaning, and appearance inspection etc.

Overhaul Steps:

1. Prior to most overhaul work, illustrative

pictures shall be observed because they will

help distinguish parts & components,

illustrate the parts fastening way, and the way

of inspecting parts appearance. In addition,

illustration explanations are attached to

dismantling/mounting procedures in need of

systematic demonstration.

2. On illustrations there are symbols of wearing

parts, tightening torque, lubricating oil, and

sealant, and also corresponding explanations

and marks are made to special tools or

equipments for dismantling or mounting.

3. Corresponding numbers are marked on

pictures for the operation sequence and parts’

major operation process. In general,

information of this kind serves as key and

core content of the diagnosis procedure. Due

to this, please refer to these materials during

the overhauling process.

Symbol

Four kinds of symbols are used in this manual to

indicate application of lubricating oil, sealant, and

special tools etc., and they imply occasions where

foresaid materials shall be applied during the

maintenance period.

“Warning”, “Caution”, “Attention”,

“Explanation”, and “Limit”.

Warning

 Warning is used to prompt that personal

injury may be caused due to negligence.

Caution

may be caused due to negligence.

Notice

 Notice is used to provide additional

information for completion of given

procedures.

Explanation

 Explanation is used to prompt the permissible

range for inspection or adjustment.

Limit

Limit is used to prompt the upper and lower limit

for the inspection or adjustment.

Inspection and Maintenance of

Complete Vehicle

Inspection of Compression Pressure

Warning

 When the engine is running, the oil

temperature is extremely high. Therefore,

keep cautious during dismantling and

mounting process since there is a danger of

burn.

1. Set the vehicle into the normal pre-inspection

state: warm up the engine to a normal running

temperature; then stop the running and cool it

for 10 minutes.

2. Dismantle the fuel pump relay (see

corresponding complete vehicle maintenance

manual).

3. Disconnect ignition coil’s wiring harness joint

(see corresponding complete vehicle

maintenance manual).

4. Dismantle Cylinder 1’s ignition coil and spark

plug(see Ignition, Control System part).

5. Mount the gauge into Cylinder 1’s spark plug

hole.

6. Floor the accelerator pedal and start the

engine.

7. Record the gauge’s maximum reading.

8. Measure all cylinders’ compression pressures

according to preceding method, and inspect if

the pressure difference between cylinders is

lower than the limit value.

Limit value (maximum): 980 (kPa)

Note: If one cylinder or several cylinders

encounter excessively low pressure, or pressure

difference between cylinders goes beyond the limit

value specified, some drops of engine oil shall be

added for repeated operation. Repeat the

inspection following Step5-7.

■ If the compression pressure increases, the

fault cause should be attributed to piston, piston

ring, or cylinder inner surface’s wearing or

damage, and in turn an overhaul is needed.

■ If the adjacent cylinder encounters low

pressure, the cylinder gasket may be damaged, or

the cylinder head likely suffers deformation, and in

turn an overhaul is needed.

■ If the compression pressure is still low, the

valve seat is burnt or in poor quality, and the

valve’s sealing face has poor contact. Thus, an

overhaul is needed.

9. Take off the gauge

10. Connect the ignition coil wiring

11. Mount the fuel pump relay

12. Mount the spark plug tightening torque:20～

30N·m{2.1～3.1kgf·m }

Inspection of the Engine Oil

1. Park the automobile on the level ground.

2. Warm up the engine to a normal running

temperature and stop the running.

Dismantle the Engine from Maintenance

Platform

Dismantle the engine from the maintenance

platform according to steps reverse to “Mount

the Engine onto Maintenance Platform”.

Notice

 The engine maintenance platform’s

self-locking brake system may lose efficacy

in an unbalanced state, for instance, the

engine maintenance platform suffers

unbalance due to sudden and rapid action

resulting from the engine mounting onto and

dismantling from the platform, which will

result in danger. Due to this, to ensure the

engine and the entire maintenance

platform’s balance during the operation

process, the maintenance platform’s rotary

handle shall be held tightly in hands during

the engine tilting process.

Smear clean oil onto the

new oil filter’s O-ring.

Power Generator and Starter

Power Generator’s

Dismantling/Mounting

Warning

 When dismantling /mounting the power

generator on the complete vehicle, the

accumulator cable shall be dismantled firstly,

or the power generator’s Terminal B will

contact the vehicle body, which will lead to

sparks and further result in personal injury

and electric element damage.

1. Dismantle the power generator according to

the sequence illustrated in the figure.

2. Mount the power generator according to the

sequence reverse to the dismantling process.

3. Inspect the belt’s deflection /tension (see

Inspection of the Power Generator Belt).

Explanations on Inspection of Power

Generator Belt

If necessary, inspect the power generator belt’s

deflection and tension: see complete vehicle

maintenance manual’s corresponding part.

Explanations on adjustment to tension of

power generator and air conditioning

drive belts

1. Loosen the power generator’s bolt nut . ①

2. Loosen the power generator’s fixing nut . ②

Use the adjusting bolt , ③ and adjust the belt

tension and belt difference to the specified value.
