Assemble so that the front mark on the piston head and the oil
holes and the cylinder number on connecting rod are posi-
tioned as shown in the figure.
c. Install new snap ring to the groove of the piston front side.

Insert it fully into groove to install.

After installing, make sure that connecting rod moves
smoothly.
9. Using piston ring expander (commercial service tool), install piston rings.
CAUTION:

Be careful not to damage piston.

Be careful not to damage piston rings by expanding them excessively.

Position each ring with the gap as shown in the figure refer-
ring to the piston front mark.

Install second ring with the stamped surface facing upward.
NOTE:
If there is no stamped mark on piston ring, no specific orienta-
tion is required for installation.
10. Inspect outer diameter of connecting rod bolts. Refer to EM-107, "
CONNECTING ROD BOLT OUTER
DIAMETER" .
11. Install connecting rod bearings to connecting rod and connecting rod cap.

When installing connecting rod bearings, apply new engine oil to the bearing surface (inside). Do not
apply new engine oil to the back surface, but thoroughly clean it.

When installing, align the connecting rod bearing stopper pro-
trusion with the cutout of connecting rod and connecting rod
cap to install.

Ensure the oil hole on connecting rod and that on the corre-
sponding bearing are aligned.
12. Install piston and connecting rod assembly to crankshaft.

Position crankshaft pin corresponding to connecting rod to be installed onto the bottom dead center.

Apply new engine oil sufficiently to the cylinder bore, piston and crankshaft pin journal.

Match the cylinder position with the cylinder number on connecting rod to install.

Install drive plate, reinforcement plate and pilot converter as
shown in the figure.

Using drift of 33 mm (1.30 in) in diameter, press-fit pilot con-
verter into the end of crankshaft until it stops.
16. Install knock sensor.

Install knock sensor with connector facing lower left by 45
degrees as shown in the figure.
CAUTION:

Do not tighten mounting bolt while holding the connec-
tor.

If any impact by dropping is applied to knock sensor,
replace it with a new one.
NOTE:

Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of knock sensor.

Make sure that knock sensor does not interfere with other
parts.
17. Install crankshaft position sensor (POS).
18. Assemble in the reverse order of disassembly after this step.
How to Select Piston and Bearing BBS0059H
DESCRIPTION
*For the service parts, the grade for fitting cannot be selected between piston pin and connecting rod. (Only grade “0” is available.) The
information at the shipment from the plant is described as a reference.

The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.

For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.

For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, refer to the text.

Inspection After DisassemblyBBS0059I
CRANKSHAFT END PLAY

Measure the clearance between thrust bearings and crankshaft
arm when crankshaft is moved fully forward or backward with
dial indicator.

If the measured value exceeds the limit, replace thrust bearings,
and measure again. If it still exceeds the limit, replace crank-
shaft also.
CONNECTING ROD SIDE CLEARANCE

Measure the side clearance between connecting rod and crank-
shaft arm with feeler gauge.

If the measured value exceeds the limit, replace connecting rod,
and measure again. If it still exceeds the limit, replace crank-
shaft also.
PISTON TO PISTON PIN OIL CLEARANCE
Piston Pin Hole Diameter
Measure the inner diameter of piston pin hole with inside microme-
ter.
Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pin hole diameter) – (Piston pin outer diameter)

If oil clearance is out of the standard, replace piston and piston pin assembly. Standard : 0.10 - 0.26 mm (0.0040 - 0.0102 in)
Limit : 0.3 mm (0.012 in)

FRONT TIMING CHAIN CASE

a. Apply a continuous bead of liquid gasket with tube presser [SST:
WS39930000] to front timing chain case back side as shown in
the figure.
Use Genuine Liquid Gasket or equivalent.
b. Install new oil pan gasket.

Apply liquid gasket to oil pan gasket as shown in the figure.
Use Genuine Liquid Gasket or equivalent.

Align notch of front timing chain case with protrusion of oil pan
gasket.

b. Install new O-rings to cylinder head.
c. Apply liquid gasket with tube presser [SST: WS39930000] to rear timing chain case back side as shown in
the figure.
Use Genuine Liquid Gasket or equivalent.
CAUTION:

For “A” in the figure, completely wipe out liquid gasket extended on a portion touching at
engine coolant.

Apply liquid gasket on installation position of water pump and cylinder head very completely.
d. Align rear timing chain case and water pump assembly with dowel pins (right and left) on cylinder block
and install rear timing chain case.

Make sure O-rings stay in place during installation to cylinder block and cylinder head.

TIMING CHAIN

a. Push plunger of chain tensioner (secondary) and keep it
pressed in with stopper pin.
b. Install timing chain (secondary) and camshaft sprockets (INT
and EXH).

Align the mating marks on timing chain (secondary) (gold link)
with the ones on camshaft sprockets (INT and EXH)
(punched), and install them.
NOTE:

Mating marks for camshaft sprocket (INT) are on the back
side of camshaft sprocket (secondary).

There are two types of mating mark, circle and oval types.
They should be used for the right and left banks, respec-
tively.

Align dowel pin and pin hole on camshafts with the groove
and dowel pin on sprockets, and install them.

On the intake side, align pin hole on the small diameter side of
the camshaft front end with dowel pin on the back side of
camshaft sprocket, and install them.

On the exhaust side, align dowel pin on camshaft front end
with pin groove on camshaft sprocket, and install them.

In case that positions of each mating mark and each dowel
pin are not fit on mating parts, make fine adjustment to the position holding the hexagonal portion on
camshaft with wrench or equivalent.

Mounting bolts for camshaft sprockets must be tightened in the next step. Tightening them by hand is
enough to prevent the dislocation of dowel pins.

It may be difficult to visually check the dislocation of mating
marks during and after installation. To make the matching
easier, make a mating mark on the top of sprocket teeth and
its extended line in advance with paint.

CAUTION:
Do not overtighten slack guide mounting bolt. It is normal
for a gap to exist under the bolt seat when mounting bolt is
tightened to specification.
9. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab up (or turn lever downward) so as to
remove plunger stopper tab from the ratchet of plunger.
NOTE:
Plunger stopper tab and lever are synchronized.
b. Push plunger into the inside of tensioner body.
c. Hold plunger in the fully compressed position by engaging
plunger stopper tab with the tip of ratchet.
d. To secure lever, insert stopper pin through hole of lever into ten-
sioner body hole.

The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.
e. Install timing chain tensioner (primary).

Remove any dirt and foreign materials completely from the
back and the mounting surfaces of timing chain tensioner (pri-
mary).
f. Pull out stopper pin after installing, and then release plunger.
10. Make sure again that the mating marks on each sprocket and each timing chain have not slipped out of
alignment.
11. Install new O-rings on rear timing chain case.
12. Install new front oil seal on front timing chain case.

Apply new engine oil to both oil seal lip and dust seal lip.
