How to use this instruction

In order to help you to look in this instruction, we marked the chapter

name and main theme at the top of each page.

In order to introduce the repairing items to you, we make the index on

the first page of each chapter, and notices need to be taken during all

repairing operation are also given in the related chapter.

Please read these notices carefully before the repairing work.

The troubleshooting form for each system will help you to diagnose

the system trouble and its cause.

We furnish with the repairing approaches for each possible cause in

the repairing approach column, which will help you to acquire the

solution in a short time.

Introduction

How to Use This Instruction

Repairing approach

Most repairing operation can begin with referring to these illustrations.

These illustrations can help you identify the parts and their coordina-

tion situation

Introduction

How to Use This Instruction

Introductionóhow to use this instruction

The repairing approaches are described step by step:



The illustrations show you what to do and at which position.



The theme of repairing operation tell you what you need to do.



The detailed instruction show you how to accomplish the repairing and

introduce to you other related affairs, such as specification, warning etc.

Example:

Check and adjust the flange bounce

(a) Attach the dial indicator seat to the reducer housing, and touch the

flange face with the measuring head of dial indicator, run the flange

and observe the pendular range of the indicator carefully.

Full bounce tolerance of face : 0.10mm

Specification

This formula can help the experienced technicians find out the failure

causes in short time. Overhauling staff can browse the operation theme

and refer to the detailed description thereunder where necessary; impor-

tant specifications and warnings are written out in boldface.

Specification

The corresponding specifications are given in boldface in each repairing

approach of this instruction, which allows the overhauling staff to check the

specification while keeping on repairing work.

Warning, Notice and Remark



Warning written out in boldface means there is possibility of self-

injury or harm to others.



Notice written out in boldface means there is possibility of damage

to parts under repairing.



Remarks singled out independently, but not in boldface, serve as

supplementary descriptions to help you accomplish the work more

efficiently.

Overall Repairing Description

1. Keep the vehicle clean and prevent it from

damage with guard plate, seat and floor cover

cloth.

2. Put down the dismantled parts in order during

the dismantle process so as to facilitate the re-

assembly

3. Observe the following items:

a) Disconnect the cable cathode from the

accumulator terminal before the electric

operation;.

b) Disconnect the cable from the cathode

connected to the vehicle body when check-

ing or repairing the accumulator where

necessary.

c)  In order to avoid the damage of terminal

post of accumulator, loose the bolts first,

then pull up the cable vertically when

dismantling, don

t wring it or prize it.

d)  Clean the terminal posts of the accumula-

tor with dishcloth, and do not scrape them

with file or other similar tools to avoid

damage.

e)  Mount the cable terminal on the post with loosened nut, then

fasten the nut. donít tap the terminal onto the post with

hammer.

f)  Be sure to check whether the cover of positive terminal (+) is

well located or not.

4. Check all hoses and wire plugs to verify whether they are

connected solidly and correctly.

5. Parts that cannot be reused after being used.

a)  The following parts should be changed with new one regularly:

split pin, sealing washer, O-ring and oil seal, etc.

b)  parts that cannot be reused after being used is marked with

  in the element figure.

6. Pre-coated parts

The pre-coated parts including the bolt and nut are coated with

locking seal glue in factory.

  a)  In case the pre-coated parts are moved due to its fastening,

loosening or other causes, they must be coated again with the

specified seal glue.

b)  Coating procedure of pre-coated parts

1) Clear away the former seal glue from the screw thread of

the said parts.

2) Dry the parts with compressed air.

3) Coat the screw thread of the parts with the specified

locking seal glue.

c)  The pre-coated parts are marked with the 

 in element

figure.

7. When necessary, sealing agent or sealing ring to prevent the

leakage.

8. Each specification shall be followed strictly. And the torque

spanners should be used.

9. Determine the necessity of using the special service tools (SST)

or special service materials (SSM) according to the real situation.

SST and SSM must be used where necessary and the repairing

should be in accordance with the repairing approach. SST list

and SSM list are attached to this instruction.

10. Be sure to check whether the rated current of the new fuse is

correct when changing the fuse. The fuse rated current should

not larger than that of securing fitting and the fuse of smaller

rated current must not be used.

11. Be careful to hang or support the vehicle on the suitable place

when propping up or raising it.

a)  In case prop up the vehicle at the front or back part, the wheels

must be blocked to guarantee the safety work.

b)  The raised vehicle must be supported with the bracket; it is

dangerous to conduct the repairing work on the vehicle propped

up with one jack, even though such repairing can be finished in

short time.

12. The following items shall be taken notice to avoid the parts damage:

a)  Do not open the covers of ECU and various computers where not

necessary absolutely. (if the IC terminal is touched, it be leaded

into static damage) .

b)  Pull the hose at its ends when dismantling it, do not pull it at the

center section.

c)  Pull the wire joint instead of the wire when pulling the joint

away.

d)  Take notice to avoid of the drop of electric parts such as the

sensors or repeaters. In case those parts drop to the hard ground,

they must be changed instead of being reused.

e)  Do not use the striking spanner to dismantle or mount the

thermostatic switch or thermostatic sensor.

f)  Plug the needles of the multi-meter into the wire connector

carefully when checking its conductance and do not bend the

terminals.

g)  Do not sheath the hose of the vacuum gauge into the very large

connector when using the gauge, instead, the stage joint shall be

used because once the hose expands, it is possible to lead into

the leakage.
