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. Power tools may be
used where noted in the step.

Precautions for Inspection, Repair and Replacement

ABS004RM

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

Precautions for Assembly and Installation

ABS004RN

●

Use torque wrench to tighten bolts or nuts to specification.

●

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 speci-
fied, do exactly as specified.

●

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

●

Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine 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 when refilling after draining engine coolant.

●

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

Parts Requiring Angular Tightening

ABS004RO

●

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

–

Cylinder head bolts

–

Main bearing cap bolts

–

Connecting rod cap nuts

–

Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)

●

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 for Liquid Gasket

ABS004RP

REMOVAL OF LIQUID GASKET SEALING

●

After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the old liquid gasket
sealing.

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
surfaces.

LIQUID GASKET APPLICATION PROCEDURE

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.

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

Attach the liquid gasket tube to the tube presser.
Use Genuine RTV silicone sealant or equivalent. Refer to

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

●

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

●

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

●

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

●

If the liquid gasket protrudes, wipe it off immediately.

●

Do not retighten after the installation.

●

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

CAUTION:

If there are specific instructions in this manual, observe
them.
