PRECAUTIONS

PRECAUTIONS

Precautions for Drain Coolant

Drain coolant when engine is cooled.

Precautions for Disconnecting Fuel Piping

[KA24DE]

PFP:00001

A

EBS007JS

EM

EBS007JT

Before starting work, make sure no fire or spark producing items are in the work area.

Release fuel pressure before disassembly.

After disconnecting pipes, plug openings to stop fuel leakage.

Precautions for Removal and Disassembly

EBS007JU

When instructed to use special service tools, use the specified tools. Always be careful to work safely, avoid forceful or uninstructed operations.

Exercise maximum care to avoid damage to mating or sliding surfaces.

Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials. Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.

When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally opposite, and so on. If the order of loosening is specified, do exactly as specified.

Precautions for Inspection, Repair and Replacement

EBS007JV

Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and replace if necessary.

Precautions for Assembly and Installation

EBS007JW

C

D

E

F

G

H

Use torque wrench to tighten bolts or nuts.

When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the

ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified, do exactly as specified.

Replace with new gasket, packing, oil seal or O-ring.

Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction and blockage.

Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well.

Release air within route after draining coolant.

After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems

for leakage.

Parts Requiring Angular Tightening

EBS007JX

Use an angle wrench for the final tightening of the following engine parts:

Cylinder head bolts

Connecting rod cap nuts

Do not use a torque value for final tightening.

The torque value for these parts are for a preliminary step.

Ensure thread and seat surfaces are clean and coated with engine oil.

PRECAUTIONS

[KA24DE]

Precautions for Liquid Gasket

EBS007JY

REMOVAL OF LIQUID GASKET SEALING

After removing the mounting bolts and nuts, disconnect and remove the liquid gasket sealing using a seal cutter.

CAUTION:

Be careful not to damage the mating surfaces.

In areas where the cutter is difficult to use, use a plastic hammer to lightly tap the areas where the liquid gasket is applied.

CAUTION:

If for some unavoidable reason a tool such as a flat-bladed screwdriver is used, be careful not to damage the mating sur-

faces.

PBIC0275E

LIQUID GASKET APPLICATION PROCEDURE

1.Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.

Remove the liquid gasket completely from the groove of the gasket application surface, mounting bolts, and bolt holes.

2.Wipe the gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove adhering moisture, grease and foreign materials.

3.Attach the liquid gasket to the tube presser.

Use Genuine Liquid Gasket or equivalent.

PBIC0003E

4.Apply the gasket without breaks to the specified location with the specified dimensions.

If there is a groove for the liquid gasket application, apply the gasket to the groove.

As for the bolt holes, normally apply the gasket inside the holes. Occasionally, it should be applied outside the holes. Make sure to read the text of service manual.

Within five minutes of gasket application, install the mating component.

If the liquid gasket protrudes, wipe it off immediately.

EMA0622D

 

Do not retighten after the installation.

After 30 minutes or more have passed from the installation, fill the engine oil and coolant.

CAUTION:

If there are specific instructions in the service manual, observe them.
