INSPECTION AFTER REMOVAL
Timing Chain
Check for cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as necessary.
INSPECTION AFTER INSTALLATION
Inspection for Leakage
The following are procedures for checking fluids leak, lubricates 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 MA-11, "
Fluids and Lubricants".

3. Install cylinder head follow the steps below to tighten cylinder
head bolts in numerical order as shown in the figure with cylin-
der head bolts wrench (commercial service tool).
CAUTION:
If cylinder head bolts reused, check their outer diameters
before installation. Refer to EM-104, "
Inspection".
Before installing cylinder head, inspect cylinder head dis-
tortion. Refer to EM-104, "
Inspection".
a. Apply new engine oil to threads and seat surfaces of cylinder
head bolts.
b. Tighten all cylinder head bolts.
c. Completely loosen all cylinder head bolts.
CAUTION:
In step “c”, loosen bolts in reverse order of that indicated in the figure.
d. Tighten all cylinder head bolts.
e. Turn all cylinder head bolts 103 degrees clockwise (angle tightening).
CAUTION:
Check the tightening angle by using the angle wrench [SST:
KV10112100 (BT8653-A)] (A). Avoid judgment by visual
inspection without.
Check tightening angle indicated on the angle wrench indica-
tor plate.
f. Turn all cylinder head bolts 103 degrees clockwise again (angle
tightening).
4. After installing cylinder head, measure distance between front
end faces of cylinder block and cylinder head (bank 1 and bank
2).
If measured value is out of the standard, reinstall cylinder
head.
5. Install in the reverse order of removal after this step.

8. Install main bearing cap bolts in numerical order as shown in the
figure as follows:
a. Inspect the outer diameter of main bearing cap bolt. Refer to
EM-119, "
Inspection".
b. Apply new engine oil to threads and seat surfaces of main bear-
ing cap bolts.
c. Tighten main bearing cap bolts in several different steps.
d. Turn all main bearing cap bolts 90 degrees clockwise (angle tightening).
CAUTION:
Use the angle wrench [SST: KV10112100 (BT8653-A)] to
check tightening angle. Never make judgment by visual
inspection.
After installing main bearing cap bolts, check that crankshaft
can be rotated smoothly by hand.
Check the crankshaft end play. Refer to EM-119, "
Inspection".
9. Install piston to connecting rod as follows:
a. Using snap ring pliers, install new snap ring to the groove of piston rear side.
Insert it fully into groove to install.
b. Install piston to connecting rod.
Using an industrial drier or similar tool, heat piston until piston pin can be pushed in by hand without
excess force [approximately 60 to 70°C (140 to 158°F)]. From the front to the rear, insert piston pin into
piston and connecting rod.
Assemble so that the front mark on the piston crown and the
cylinder number on connecting rod are positioned 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, check that connecting rod moves smoothly.
10. Using a piston ring expander (commercial service tool) (A),
install piston rings.
CAUTION:
When installing piston rings, be careful not to damage
piston.
Be careful not to damage piston rings by expending them

CAUTION:
Always use the angle wrench [SST: KV10112100 (BT8653-
A)]. Avoid tightening based on visual check alone.
After tightening connecting rod bolts, check that crankshaft
rotates smoothly.
Check the connecting rod side clearance. Refer to EM-119,

1. Place the screen.
NOTE:
Stop the vehicle at the perpendicular angle to the wall.
Set the screen so that it is perpendicular to a level load surface.
2. Face the vehicle squarely toward the screen and make the distance between the headlamp center and
the screen 10 m (32.8 ft).
3. Start the engine and illuminate the headlamp (LO).
NOTE:
Block light from the headlamp that is not being adjusted with a thick fabric or another object, so that it
does not reach the adjustment screen.
CAUTION:
Do not cover lens surface with tape, etc. because it is made from plastic.
4. Use the aiming adjustment screw to adjust the elbow point projected by the low beams on the screen, so
that it is within the aiming adjustment area.
