Cylinder Bore Inner Diameter
Using a bore gauge, measure the cylinder bore for wear, out-of-
round and taper at six different points on each cylinder. (“X” and
“Y” directions at “A”, “B” and “C”) (“Y” is in longitudinal direction of
the engine)
NOTE:
When determining cylinder bore grade, measure cylinder bore at
“B” position.
If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall,
replace cylinder block.
NOTE:
There is no service setting for oversized piston.
Piston Skirt Diameter
Measure the outer diameter of piston skirt with a micrometer.
Piston to Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bore inner diameter (direction “X”, position “B”).
(Clearance) = (Cylinder bore inner diameter) – (Piston skirt diameter)
If it exceeds the limit, replace piston and piston pin assembly and/or cylinder block.
CRANKSHAFT MAIN JOURNAL DIAMETER
Measure the outer diameter of crankshaft main journals with a
micrometer (A).
If out of the standard, measure the main bearing oil clearance.
Then use undersize bearing.

rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precaution for Drain CoolantINFOID:0000000001337765
Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000001337766
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.
Precaution for Removal and DisassemblyINFOID:0000000001337767
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 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
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000001337768
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000001337769
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 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.
Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for
leakage.

Use an angle wrench for the final tightening of the following engine parts:
- Cylinder head bolts
- Camshaft sprocket (INT)
- 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. Tool number : KV10112100 (BT-8653-A)
EM-136
< PRECAUTION >[MR18DE]
PRECAUTIONS
The torque value for these parts are for a preliminary step.
Ensure thread and seat surfaces are clean and coated with engine oil.
Precaution for Liquid GasketINFOID:0000000001337771
REMOVAL OF LIQUID GASKET SEALING
After removing the bolts and nuts, separate the mating surface and
remove the sealant using Tool.
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 (1) the cutter where the RTV Silicone Sealant is applied.
Use a plastic hammer to slide the cutter (2) by tapping on the side.
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.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old Silicone RTV Sealant adhering
to the gasket application surface and the mating surface.
Remove the sealant completely from the groove of the gasket
application surface, bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating
surface and remove adhering moisture, grease and foreign
materials.
3. Attach the sealant tube to the tube presser.
Use Genuine Silicone RTV Sealant or equivalent. Refer to
GI-27, "
Recommended Chemical Products and Sealants".
4. Apply the sealant without breaks to the specified location using
Tool.
If there is a groove for the sealant application, apply the seal-
ant to the groove.
As for the bolt holes, normally apply the sealant inside the
holes. If specified, it should be applied outside the holes. Make
sure to read the text of this manual.
Within five minutes of the sealant application, install the mat-
ing component.
If the sealant protrudes, wipe it off immediately.
Do not retighten after the installation.
After 30 minutes or more have passed from the installation, fill
the engine with the specified oil and coolant. Refer to MA-19,
"Fluids and Lubricants".
