< PRECAUTION >

[MR20DE]

PRECAUTIONS

• When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or unin-

structed operations.

• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,

make sure that dowel pins are installed in the original position.

• Cover openings of engine system with a tape or 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. Power tools may be used
in the step.

Inspection, Repair and Replacement

INFOID:0000000000893913

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

Assembly and Installation

INFOID:0000000000893914

• 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 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 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 the engine and increase engine speed to check engine coolant, fuel, engine oil, and

exhaust gases for leakage.

Parts Requiring Angle Tightening

INFOID:0000000000893915

• Use the angle wrench [SST: KV10112100] for the final tightening of the following engine parts:
- Camshaft sprocket (INT) bolt
- Cylinder head bolts
- Main bearing cap bolts
- Connecting rod cap bolts
- Crankshaft pulley bolt (No the angle wrench is required as bolt flange is provided with notches for angle

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.

Liquid Gasket

INFOID:0000000000893916

REMOVAL OF LIQUID GASKET SEALING

• After removing mounting nuts and bolts, separate the mating sur-

face using the seal cutter (SST) and remove old liquid gasket seal-
ing.

CAUTION:

Be careful not to damage the mating surfaces.

• Tap the seal cutter to insert it (1), and then slide it (2) by tapping on

the side as shown in the figure.

• In areas where the seal cutter (SST) is difficult to use, use a plastic

hammer to lightly tap the parts, to remove it.

CAUTION:

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

1.

Using a scraper, remove old liquid gasket adhering to the liquid
gasket application surface and the mating surface.
• Remove liquid gasket completely from the groove of the liquid

gasket application surface, mounting bolts, and bolt holes.

2.

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.

3.

Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine Liquid Gasket or equivalent.

4.

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 five minutes of liquid gasket application, install the mat-

ing 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 manuals in this instruction, observe
them.
