15. REMOVE CAMSHAFT
(a) Using several steps, loosen and remove the 10 camshaft
bearing cap bolts uniformly in the sequence shown in the
illustration.
(b) Remove 5 camshaft bearings.
(c) Remove the camshaft.
(d) Tie the timing chain as shown in the illustration.
NOTICE:

Be careful not to drop anything inside the timing
chain cover.

Do not expose the chain to water, and prevents dust.
16. REMOVE CAMSHAFT TIMING GEAR ASSY
(a) Clamp the camshaft in a vise, and make sure the cam-
shaft timing gear does not rotate.
(b) Cover all the oil ports with vinyl tape except an advance
side port shown in the illustration.
(c) Put air pressure into the oil port with 150 kpa (1.5 kgf/cm
2
21 psi), and turn the camshaft timing gear to the advance
direction (counterclockwise) by hand.
CAUTION:
Cover the ports with shop rag to avoid oil splashing.
HINT:
Depending on the air pressure, the camshaft timing gear will
turn to the advance angle side without applying force by hand.
Also, under the condition that the pressure can be hardly ap-
plied because of the air leakage from the port, there may be the
case that the lock pin could be hardly released.

(d) Remove a fringe bolt of camshaft timing gear.
NOTICE:

Be sure not to remove the other 4 bolts.

If reusing the camshaft timing gear, release the
straight pin lock first, and then install the gear.
17. INSTALL CAMSHAFT TIMING GEAR ASSY
(a) Put the camshaft timing gear and the camshaft together
with the straight pin off the key groove.
(b) Turn the camshaft timing gear assembly to the left direc-
tion (as shown in the illustration) while lightly pushing it to-
ward the camshaft. Push further at the position where the
pin gets into the groove.
NOTICE:
Be sure not to turn the camshaft timing gear to the retard
angle side (to the right direction).
(c) Check that there is no clearance between the gear's
fringe and the camshaft.
(d) Tighten the fringe bolt with the camshaft timing gear fixed.

(e) Check that the camshaft timing gear can move to the re-
tard angle side (to the right direction), and is locked at the
most retarded position.
18. INSTALL CAMSHAFT
(a) Turn the crankshaft pulley, and align its groove with timing
mark 0 of the timing chain cover.
(b) Install the timing chain on the camshaft timing gear, with
the painted links aligned with the timing marks on the
camshaft timing gear.

HINT:
Since each injector assembly has a characteristic fuel injecting behavior, store them in correct order so that
they can be returned to the original locations when re±assembling. 35. REMOVE CAMSHAFT OIL SEAL RETAINER
(a) Remove the 4 bolts.
(b) Using a screwdriver, remove the oil seal retainer by pryingbetween the oil seal retainer and the camshaft bearing
cap.
36. REMOVE CAMSHAFT

tion.
(b) Remove the 5 bearing caps and the camshaft sub±assy.
37. REMOVE NO.2 CAMSHAFT
(a) Remove the camshaft sub±assy and the camshaft carrier. 38. REMOVE CAMSHAFT OIL SEAL

40. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Using the crankshaft pulley bolt, turn the crankshaft to set
the dot mark of the crankshaft timing pulley at the position
of 90
BTDC.
NOTICE:
If the timing belt is disengaged, having the crankshaft tim-
ing pulley at wrong angle can cause the piston head and
valve head to come into contact with each other.
41. INSTALL CAMSHAFT
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being installed. If the
camshaft is not kept level, damage to the cylinder head or
the camshaft may result. To avoid this, the following proce-
dures should be carried out.
(a) Place the camshaft carrier on the cylinder head.
(b) Install the camshaft sub±assy No. 1.
(c) Apply engine oil to the cam and gear of the camshaft, and
the journal of the camshaft carrier.
(d) Place the intake camshaft on the camshaft carrier as
shown in the illustration so that the No. 3 and No. 4 of cyl-
inder cam lobes face downward.
42. INSTALL NO.2 CAMSHAFT
(a) Install the camshaft sub±assy No. 2.
(b) Apply engine oil to the cam and gear of the camshaft, and
the journal of the camshaft carrier.
(c) Engage the exhaust camshaft gear and the intake cam-
shaft gear by aligning the alignment marks on each gear.
(d) Roll down the exhaust camshaft onto the bearing journals
while engaging gears with each other.

(a) Remove any old packing (FIPG) material and be carefulnot to drop any oil on the contact surfaces of the oil seal
retainer and the cylinder block.
(1) Thoroughly clean all components to remove all theloose material.
(2) Using non±residue solvent, clean both sealing sur- faces.

(1) Install a nozzle that has been cut to a 2 to 4 mm(0.08 to 0.16 in.) opening.
(2) Parts must be assembled within 15 minutes of ap- plication. Otherwise the material must be removed
and reapplied.
(3) Immediately remove nozzle from the tube and rein- stall the cap.
