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)
1st 20 (2.0, 14) 98 (10, 72)
2nd 98 (10, 72) 20 (2.0, 14)
3rd 167 - 176 (17 - 18, 123 - 130) 40 - 46 (4.0 - 4.7, 29 - 33)
I Sub-bolt No. 17 has shorter length than that of other sub-bolts.

6. Install mounting bolts for engine sub-attachment shown byarrows in the figure.
I After tightening bolts to the specified torque, check crankshaft
for smooth rotation.
I Check crankshaft end play.
Refer to EM-71, ªCRANKSHAFT END PLAYº.
7. Install pistons to connecting rod.
1) Using long nose pliers, install snap rings to grooves on piston rear side.
I Fit snap rings correctly into grooves.
2) Install pistons to connecting rods.
I Using industrial dryer, heat pistons up to approx. 60 to 70ÉC
(140 to 158ÉF) until piston pin can be pressed down by finger
touch. Then insert piston pins into piston and connecting rod
from front side of piston toward rear.
I Assemble piston and connecting rod with front mark of piston
crown and cylinder No. stamped on connecting rod being posi-
tioned as shown in the figure.
3) Install snap rings to front side of pistons.
I Refer to above 1) for precaution on snap ring installation.
I After installation, check connecting rods for smooth movement.
8. Use piston ring expander (multi-purpose tool) to install piston rings.
CAUTION:
When installing, prevent piston from being damaged.
I Install top ring and second ring with stamped surfaces facing
upward.
Identification stamp: Top ring: R
Second ring: RN
9. Install connecting rod bearings to connecting rods and caps.
I While installing connecting rod bearings, apply engine oil to
bearing surfaces (inside). Do not apply oil to rear surfaces, but
clean them completely.
I Align stoppers on connecting rod bearings with connecting rod
stopper notches to install connecting rod bearings.

10. Install piston and connecting rod assembly to crankshaft.
IMove crankshaft pin to be removed to BDC.
I Align cylinder position with cylinder No. on connecting rod to
install piston and connecting rod assembly.
I Using piston ring compressor (multi-purpose tool), install piston
and connecting rod assembly with front mark on piston crown
facing toward the front side of engine.
CAUTION:
When installing piston and connecting rod assembly, prevent
the big end of connecting rod from interfering with oil jet.
11. Install connecting rod caps and mounting nuts.
I Align cylinder No. stamped on connecting rod with that on cap
to install connecting rod cap.
I After tightening nuts, check crankshaft for smooth rotation.
I Check connecting rod side clearance.
Refer to EM-71, ªCONNECTING ROD SIDE CLEARANCEº.
12. Install rear oil seal and retainer assembly.
I Apply a continuous bead of liquid gasket to rear oil seal and
retainer assembly as shown in the figure.
13. Press fit pilot bushing into flywheel (M/T model).
1) Using drift with outer diameter of 35 mm, press fit spacer until it is in contact with the flywheel to prevent displacement at
removal.
2) Using drift with outer diameter of 20 mm, press fit pilot bushing by the length shown in the figure.
14. Install rear plate.
15. Install removed parts to engine in the reverse order of disas- sembly.
16. Remove engine from engine stand.

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.
