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 in the step.

Precautions for Inspection, Repair and Replacement

ABS00A7P

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

Precautions for Assembly and Installation

ABS00A7Q

●

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 gases for leakage.

Parts Requiring Angle Tightening

ABS00A7R

●

Use angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:

–

Cylinder head bolts

–

Main bearing cap bolts

–

Connecting rod cap bolts

–

Crankshaft pulley bolt (No angle wrench is required as bolt flange is provided with notches for angle tight-
ening)

●

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

Revision: 2004 November

Precautions for Liquid Gasket

ABS00A7S

REMOVAL OF LIQUID GASKET SEALING

●

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

CAUTION:

Be careful not to damage the mating surfaces.

●

Tap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

●

In areas where seal cutter [SST] is difficult to use, use plastic
hammer to lightly tap the parts, to remove it.

CAUTION:

If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.

LIQUID GASKET APPLICATION PROCEDURE

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

●

Remove liquid gasket completely from the groove of the gas-
ket 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 liquid gasket tube to tube presser [SST: WS39930000
(

—

)].

Use Genuine RTV Silicone Sealant or equivalent. Refer to

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

●

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

●

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

●

Within 5 minutes of liquid gasket application, install the mating
component.

●

If liquid gasket protrudes, wipe it off immediately.

●

Do not retighten mounting bolts or nuts after the installation.

●

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

CAUTION:

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