HOW TO USE THIS MANUAL

E5U000000000E01

Range of Topics

•This manual contains procedures for performing all required service operations. The procedures are divided

into the following five basic operations:

—Removal/Installation

—Disassembly/Assembly

—Replacement

—Inspection

—Adjustment

•Simple operations which can be performed easily just by looking at the vehicle (i.e., removal/installation of

parts, jacking, vehicle lifting, cleaning of parts, and visual inspection) have been omitted.

Service Procedure

Inspection, adjustment

•Inspection and adjustment procedures are

divided into steps. Important points regarding the

location and contents of the procedures are

explained in detail and shown in the illustrations.

Repair procedure

1. Most repair operations begin with an overview illustration. It identifies the components, shows how the parts fit

together, and describes visual part inspection. However, only removal/installation procedures that need to be

performed methodically have written instructions.

2. Expendable parts, tightening torques, and symbols for oil, grease, and sealant are shown in the overview

illustration. In addition, symbols indicating parts requiring the use of special service tools or equivalent are also

shown.

3. Procedure steps are numbered and the part that is the main point of that procedure is shown in the illustration

with the corresponding number. Occasionally, there are important points or additional information concerning a

procedure. Refer to this information when servicing the related part.

UNITS

E5U000000000E02

Conversion to SI Units (Système International d'Unités)

•All numerical values in this manual are based on SI units. Numbers shown in conventional units are converted

from these values.

Rounding Off

•Converted values are rounded off to the same number of places as the SI unit value. For example, if the SI unit

value is 17.2 and the value after conversion is 37.84, the converted value will be rounded off to 37.8.

Upper and Lower Limits

•When the data indicates upper and lower limits, the converted values are rounded down if the SI unit value is

an upper limit and rounded up if the SI unit value is a lower limit. Therefore, converted values for the same SI

unit value may differ after conversion. For example, consider 2.7 kgf/cm

in the following specifications:

210—260 kPa {2.1—2.7 kgf/cm

, 30—38 psi}

270—310 kPa {2.7—3.2 kgf/cm

, 39—45 psi}

•The actual converted values for 2.7 kgf/cm

are 264 kPa and 38.4 psi. In the first specification, 2.7 is used as

an upper limit, so the converted values are rounded down to 260 and 38. In the second specification, 2.7 is

used as a lower limit, so the converted values are rounded up to 270 and 39.

FUNDAMENTAL PROCEDURES

E5U000000000E03

Preparation of Tools and Measuring Equipment

•Be sure that all necessary tools and measuring

equipment are available before starting any work.

Special Service Tools

•Use special service tools or equivalent when they

are required.

Disassembly

•If the disassembly procedure is complex,

requiring many parts to be disassembled, all parts

should be marked in a place that will not affect

their performance or external appearance and

identified so that reassembly can be performed

easily and efficiently.

Inspection During Removal, Disassembly

•When removed, each part should be carefully

inspected for malfunction, deformation, damage

and other problems.

Arrangement of Parts

•All disassembled parts should be carefully

arranged for reassembly.

•Be sure to separate or otherwise identify the parts

to be replaced from those that will be reused.

Cleaning of Parts

•All parts to be reused should be carefully and

thoroughly cleaned in the appropriate method.

Warning

•Using compressed air can cause dirt and

other particles to fly out causing injury to

the eyes. Wear protective eye wear

whenever using compressed air.

Reassembly

•Standard values, such as torques and certain

adjustments, must be strictly observed in the

reassembly of all parts.

•If removed, the following parts should be replaced

with new ones:

—Oil seals

—Gaskets

—O-rings

—Lockwashers

—Cotter pins

—Nylon nuts

•Depending on location:

—Sealant and gaskets, or both, should be

applied to specified locations. When sealant

is applied, parts should be installed before

sealant hardens to prevent leakage.

—Oil should be applied to the moving

components of parts.

—Specified oil or grease should be applied at

the prescribed locations (such as oil seals)

before reassembly.

Adjustment

•Use suitable gauges and testers when making

adjustments.

Rubber Parts and Tubing

•Prevent gasoline or oil from getting on rubber

parts or tubing.

Hose Clamps

•When reinstalling, position the hose clamp in the

original location on the hose and squeeze the

clamp lightly with large pliers to ensure a good fit.

Torque Formulas

•When using a torque wrench-SST or equivalent

combination, the written torque must be

recalculated due to the extra length that the SST

or equivalent adds to the torque wrench.

Recalculate the torque by using the following

formulas. Choose the formula that applies to you.

A : The length of the SST past the torque wrench drive.

L : The length of the torque wrench.

Vise

•When using a vise, put protective plates in the

jaws of the vise to prevent damage to parts.
