CYLINDER BLOCK TOP SURFACE DISTORTION
I Using scraper, remove gasket installed onto cylinder block sur-
face. Remove contamination such as oil, scale, and carbon.
CAUTION:
Keep broken pieces of gasket clear of oil and coolant pas-
sages.
I Use straightedge and feeler gauge to check block upper sur-
face for distortion.
Limit: 0.1 mm (0.004 in)
MAIN BEARING HOUSING INNER DIAMETER
I Install main bearing caps without main bearings. Tighten
mounting bolts to the specified torque.
I Use bore gauge to measure main bearing housing inner diam-
eter.

I If out of specification, replace cylinder block and lower cylinder
block.

IUsing bore gauge, measure cylinder inner diameters at 6 posi-
tions; top, middle, and bottom (A, B, C) in 2 directions (X, Y).

Assembly
1. Blow air sufficiently to inside coolant passage, oil passage,crankcase, and cylinder bore to remove foreign matter.
2. Install main bearings and thrust bearings.
1) Remove contamination, dust and oil from bearing mounting positions on cylinder block and main bearing caps.
2) Install thrust bearings on both sides of No. 4 housing on cylin- der block.
I Install thrust bearings with oil groove facing to crankshaft arm
(outside).
3) Being careful with the direction, install main bearings.
I Install main bearings with the oil holes and grooves onto the
cylinder block side, and those without oil holes and grooves
onto the lower cylinder block side.
I While installing bearings, apply engine oil to bearing surfaces
(inside). Do not apply oil to rear surfaces, but clean them com-
pletely.
I Align stopper notches on bearings to install them.
I Check that the oil holes on the cylinder block body are mated
with the oil hole positions on the bearings.
3. Install crankshaft to cylinder block.
I While rotating crankshaft by hand, check for smooth rotation.
4. Install lower cylinder block.
I Apply a continuous bead of liquid gasket to lower cylinder block
as shown in the figure.
I Using slots on engine sub-attachment, install the lower cylinder
block to the cylinder block, avoiding interference of dowel pins.
5. Tighten lower cylinder mounting bolts to the torque shown below in 3 consecutive steps in the order shown in the figure.
Unit: N ×m (kg-m, ft-lb)
Main bolt (Nos. 1 - 10) Sub-bolt (Nos. 11 - 20)

Parts Requiring Angular Tightening
ISome important engine parts are tightened using an angular-
tightening method rather than a torque setting method.
I If these parts are tightened using a torque setting method, dis-
persal of the tightening force (axial bolt force) will be two or
three times that of the dispersal produced by using the correct
angular-tightening method.
I Although the torque setting values (described in this manual)
are equivalent to those used when bolts and nuts are tightened
with an angular-tightening method, they should be used for
reference only.
I To assure the satisfactory maintenance of the engine, bolts and
nuts must be tightened using an angular-tightening method.
I Before tightening the bolts and nuts, ensure that the thread and
seating surfaces are clean and then coated with engine oil.
I The bolts and nuts which require the angular-tightening method
are as follows:
(1) Cylinder head bolts
(2) Connecting rod cap nuts
Liquid Gasket Application Procedure
a. Before applying liquid gasket, use a scraper to remove all
traces of old liquid gasket from mating surface and
grooves, and then completely clean any oil stains from
these portions.
b. Apply a continuous bead of liquid gasket to mating sur- faces. (Use Genuine Liquid Gasket or equivalent.)
IBe sure liquid gasket is 3.5 to 4.5 mm (0.138 to 0.177 in)
wide (oil pan).
I Be sure liquid gasket is 2.0 to 3.0 mm (0.079 to 0.118 in)
wide (in areas except oil pan).
c. Apply liquid gasket to inner surface around hole perimeter. (Assembly should be done within 5 minutes after coating.)
d. Wait at least 30 minutes before refilling engine oil and engine coolant.
