Chapter Six Disassembly of A/C Compressor

I. Disassembly Procedure

Before disassembling the compressor, disassemble the steering oil pump first.

1. Use a 12# sleeve and a universal joint connecting rod to

loosen the connecting bolt of A/C high and low pressure

pipelines. (Note: if there is R134a in the condenser, use a

special equipment to reclaim first.)

After

the

pipeline

is

loosened, immediately block high

and low pressure holes of the compressor

with clean cotton cloth to avoid entry of

foreign material into the compressor!

2. Hoist the vehicle and then use a 13# sleeve to loosen the

fixing bolt of the compressor from underside.

Torque: 20+5Nm.

3. Lower the vehicle and then use a 13# sleeve to loosen

the fixing bolt of the compressor from upside. Use a 13#

sleeve to loosen the fixing bolt at middle of the

compressor, and then dismount the compressor assembly.

Torque: 20+5Nm.

II. Overhaul of Compressor

Inside of the compressor are assembled with highly machined fine parts, in case abnormal noise or

internal failure is found, replace the assembly.

III. Installation procedure

For the installation order, please refer to the disassembly order, and then follow the order adverse

to that for disassembly to install. It should be noted that, when installing the A/C pipeline joint on

the compressor, be sure to replace with a new gasket and tight the joint at specified torque to avoid

leak.

Chapter Seven Disassembly of Generator

I. Disassembly Procedure

1. Use a 10# sleeve to remove the connecting line of

battery.

2. Use a 10# sleeve to loosen the fixing bolt of generator

adjusting bracket, and then take off the adjusting bracket.

Torque: 30+5Nm.

Before disassembling the

generator, remove the connecting

line of battery first.

3. Use a 13# sleeve to remove lower fixing bolt of the

generator.

Torque: 40+5Nm.

4. Use a 10# sleeve to remove the fixing bolt of generator

anode harness, pull out the harness connector, remove the

belt and then take out the generator.

II. Overhaul of Generator

In case the generator makes abnormal noise or its yield is too high or too low, replace the

assembly.

III. Installation Procedure

The installation order of the generator is adverse to that for its disassembly. After the generator is

installed, adjust deflection of the belt.

Chapter Eight Replacement of Engine Timing Belt

I. Disassembly Procedure

1. Disassembly of engine timing belt:

1.1 Follow the disassembly methods for power-assisted steering pump, compressor and generator

to disassemble the generator and compressor belt.

1.2 Use a 5mm hexagon wrench to remove the five

fixing bolts on timing upper cover.

1.3 The positions of the five fixing bolts on timing upper

cover are shown by the red circles in the figure.

1.4 Use a 13# sleeve to loosen the crankshaft timing

adjusting hole bolt. (The adjusting bolt is at upside of the

starter)

In order to ensure normal and

highly effective working of the

engine, replacing the timing belt at

50,000km mileage is recommended.
