CYLINDER BLOCK
Never rotate crankshaft.
 Remove connecting rod cap and bearing, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
 Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-
ified torque. Refer to EM-101, "
Disassembly and Assembly".
 Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)
 If the clearance exceeds the limit, select proper main bearing
according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-119, "
MainBearing".
Method of Using Plastigage
 Remove engine oil and dust on crankshaft main journal and the surfaces of each bearing completely.
 Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-
ified torque. Refer to EM-101, "
Disassembly and Assembly".
CAUTION:
Never rotate crankshaft.
 Remove main bearing cap and bearings, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.

 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".

 Replace timing chain and/or oil pump drive chain if necessary.
INSTALLATION
NOTE:
The figure shows the relationship between the matching mark on
each timing chain and that on the corresponding sprocket, with the
components installed.
1. Make sure that crankshaft key points straight up.
NOTE:
*: There are two outer grooves in camshaft sprocket (INT). The wider one is a matching mark.
2. If the timing chain tension guide (front cover side) is removed, install it to the front cover.
CAUTION:
Check the joint condition by sound or feeling.
3. Install crankshaft sprocket (2), oil pump sprocket (3) and oil
pump drive chain (1).
 Install it by aligning matching marks on each sprocket and oil
pump drive chain.
 If these matching marks are not aligned, rotate the oil pump
shaft slightly to correct the position.
CAUTION:
Check matching mark position of each sprocket after
installing the oil pump drive chain.

ENGINE ASSEMBLY
 When installation directions are specified, install parts according to the directions. Refer to EM-207, "Com-
ponent".
 Prior to installing the upper torque rod, apply a light coat of silicone
lubricant (A) to the washer facing side of the bushing inner tube as
shown.
NOTE:
 Apply silicone lubricant (A) by dabbing the outward facing tube
surface with a sponge or suitable tool.
 Do not apply excess lubricant.
 Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.
 Tighten engine mounting insulator (RH) bolts in the numerical
order shown.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
 Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to LU-15, "
Inspection", CO-35, "Inspection".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
 Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
 Bleed air from lines and hoses of applicable lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
