gears are aligned with the timing marks of the
bearing cap as shown in the illustration. If not, turn
the crankshaft 1 revolution (360
) and align the
timing marks as above.

INSPECTION
1. INSPECT VALVE LASH ADJUSTER ASSEMBLY
NOTICE:
• Keep the lash adjuster free from dirt and foreign
objects.
• Only use clean engine oil.
(a) Place the lash adjuster into a container full of engine
oil.
(b) Insert the SST's tip into the lash adjuster's plunger
and use the tip to press down on the checkball
inside the plunger.
SST 09276-75010
(c) Squeeze the SST and lash adjuster together to
move the plunger up and down 5 to 6 times.
(d) Check the movement of the plunger and bleed the
air.
OK:
Plunger moves up and down.
NOTICE:
When bleeding high-pressure air from the
compression chamber, make sure that the tip of
the SST is actually pressing the checkball as
shown in the illustration. If the checkball is not
pressed, air will not bleed.
(e) After bleeding the air, remove SST. Then try to
quickly and firmly press the plunger with a finger.
OK:
Plunger is very difficult to move.
If the result is not as specified, replace the lash
adjuster.
2. INSPECT CAMSHAFT
(a) Inspect the camshaft for runout.
(1) Place the camshaft on V-blocks.
(2) Using a dial indicator, measure the circle runout
at the center journal.
Maximum circle runout:
0.04 mm (0.0016 in.)
If the circle runout is greater than the
maximum, replace the camshaft.
HINT:
Check the oil clearance after replacing the
camshaft.

(d) Align the front marks of the piston and connecting
rod, and push in the piston pin with your thumb.
HINT:
The piston and pin are a matched set.
(e) Check the fitting condition between the piston and
piston pin by trying to move the piston back and
forth on the piston pin.
(f) Using a screwdriver, install a new snap ring at the
other end of the piston pin hole.
HINT:
Be sure that the end gap of the snap ring is not
aligned with the pin hole cutout portion of the piston.
4. INSTALL PISTON RING SET
(a) Install the oil ring expander and 2 side rails by hand.
(b) Using a piston ring expander, install the 2
compression rings so that the painted marks are
positioned as shown in the illustration.

11. INSTALL NO. 1 STRAIGHT SCREW PLUG
(a) Using a 10 mm hexagon wrench, install 4 new
gaskets and the straight screw plugs.
Torque: 44 N*m (449 kgf*cm, 32 ft.*lbf)
12. INSTALL VALVE SPRING SEAT
(a) Install the valve spring seats to the cylinder head.
13. INSTALL INTAKE VALVE STEM OIL SEAL
(a) Apply a light coat of engine oil to new oil seals.
NOTICE:
Pay attention when installing the intake and
exhaust oil seals. For example, installing the
intake oil seal into the exhaust side or installing
the exhaust oil seal to the intake side can cause
installation problems later.
HINT:
The intake valve oil seals are white and the exhaust
valve oil seals are black.
(b) Using SST, push in the oil seals.
SST 09201-41020
NOTICE:
Failure to use SST will cause the seal to be
damaged or improperly seated.
14. INSTALL INTAKE VALVE
(a) Apply plenty of engine oil to the tip area of the intake
valve shown in the illustration.
(b) Install the valve, compression spring and spring
retainer to the cylinder head.
NOTICE:
Install the same parts in the same combination
to original locations.

(c) Using SST and wooden blocks, compress the
spring and install the retainer lock.
SST 09202-70020 (09202-00010)
(d) Using a plastic-faced hammer, lightly tap the valve
stem tip to ensure a proper fit.
NOTICE:
Be careful not to damage the retainer.
15. INSTALL EXHAUST VALVE
(a) Apply plenty of engine oil to the tip area of the
exhaust valve shown in the illustration.
(b) Install the valve, compression spring and spring
retainer to the cylinder head.
NOTICE:
Install the same parts in the same combination
to their original locations.
(c) Using SST and wooden blocks, compress the
spring and install the retainer lock.
