CYLINDER BLOCK
If the calculated value exceeds the limit, select
proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer to
EM-134, "
How to Select Piston and Bearing".
Method of Using Plastigage
Remove oil and dust on crankshaft pin 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 connecting rod bearings to connecting rod and connecting rod bearing cap, and tighten connecting rod bolts to the specified torque. Refer to EM-123, "
Disassembly and Assembly" for the tightening proce-
dure.
CAUTION:
Do not rotate crankshaft.
Remove connecting rod 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”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
Install main bearings to cylinder block and main bearing caps, and
tighten main bearing cap bolts with main bearing beam to the
specified torque. Refer to EM-123, "
Disassembly and Assembly"
for the tightening procedure.
Measure the inner diameter of main bearing with a bore gauge.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)
If the calculated value exceeds the limit, select proper main bearing according to main bearing inner diame-
ter and crankshaft main journal diameter to obtain the specified bearing oil clearance. Refer to EM-134,
"How to Select Piston and Bearing".
Method of Using Plastigage
Remove engine oil and dust on crankshaft 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 bearing to cylinder block and main bearing cap, and tighten main bearing bolts with main bear-
ing beam to the specified torque. Refer to EM-123, "
Disassembly and Assembly" for the tightening proce-
dure.
CAUTION:
Never rotate crankshaft.

Precaution for Assembly and InstallationINFOID:0000000001325756
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.
Guide pins are used for several parts alignment. When replacing and reassembling parts with guide pins, make sure that guide pins are installed in the original portion.
Avoid damaging sliding or mating surfaces. Completely re move 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 TighteningINFOID:0000000001325757
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 nuts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angletightening)
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.
Precaution for Liquid GasketINFOID:0000000001325758
REMOVAL OF LIQUID GASKET SEALING
After removing mounting nuts and bolts, separate the mating sur- face 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 ham-
mer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reaso n tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using 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.
