25. REMOVE TIMING BELT NO.3 COVER
(a) Disconnect the 3 engine wire harness clamps from the
timing belt No. 3 cover.
(b) Remove the 6 bolts and timing belt cover.
26. REMOVE CAMSHAFT
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while being removed. If the
camshaft is not kept level, the cylinder head or camshaft
may be damaged. To avoid this, the following steps must
be carried out.
(a) Align the timing marks (2 dot marks) of the camshaft drive
and driven gears by turning the camshaft with a wrench.
(b) Secure the exhaust camshaft sub gear to the main gear
with a service bolt.
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
Recommended service bolt
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 to 20 mm
HINT:
When removing the camshaft, make certain that the torsional
spring force of the sub gear has been eliminated by installation
of the service bolt.
(c) Using several steps, loosen and remove the 10 bearing
cap bolts uniformly in the sequence shown in the illustra-
tion. Remove the 5 bearing caps and camshaft.
NOTICE:
Do not pry out the camshaft.
Be careful not to damage the contact surface of the
cylinder head that receives the shaft thrust.

33. INSTALL CAMSHAFT
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while being installed. If the
camshaft is not kept level, the cylinder head or camshaft
may be damaged. To avoid this, the following steps must
be carried out.
(a) Apply new engine oil to the thrust portion and journal of
the camshaft.
(b) Align the timing marks (2 dot marks) of the camshaft drive
and driven gears.
(c) Place the camshaft on the cylinder head.
(d) Install the 5 bearing caps in their proper locations.
(e) Apply a light coat of engine oil to the threads of the bear-
ing cap bolts.
(f) Using several steps, tighten the 10 bearing cap bolts uni-
formly in the sequence shown in the illustration.
Torque: 16 NVm (163 kgfVcm, 12 ftVlbf)
(g) Remove the service bolt.
34. INSTALL TIMING BELT NO.3 COVER
(a) Visually check for cracks and breaks on the gasket of the
timing belt cover.
HINT:
If there is a trace of water intrusion when checking visually, re-
pair the gasket with seal packing when the crack length is within
2 to 3 cm (0.79 to 1.18 in.). Replace the gasket when the crack
length is 3 to 4 cm (1.18 to 1.57 in.) or longer.

(b) If the timing belt cover gasket is needed to repair, follow
the procedure below.
(1) Repair the cracks and breaks by applying seal
packing to the damaged area.
Seal packing: Part No. 08826-00080 or equivalent
NOTICE:
When applying the seal packing, apply it as wide and high
as the gasket.
(c) If the timing belt cover gasket is needed to replace, follow
the procedure below.
(1) Using a screwdriver and gasket scraper, remove
the remaining gasket.
NOTICE:
Be careful not to damage the timing belt cover.
(2) Remove the backing paper from a new gasket, then
affix the gasket along the groove of the timing belt
cover as shown in the illustration.
NOTICE:
Affix the gasket in the center of the groove.
At the corners, try to keep the gasket thickness uni-
form.

NOTICE:
When applying the seal packing, apply it as wide and high

(d) Install the timing belt cover with the 6 bolts.
Torque: 8.5 NVm (87 kgfVcm, 75 in.Vlbf)
35. INSTALL CAMSHAFT TIMING PULLEY
(a) Pay attention to the orientation of the belt guide. Install
the camshaft timing pulley with the belt guide properly ori-
ented, then tighten the bolt temporarily.
HINT:
Align the belt guide of the RH timing pulley so it faces the
front of the engine as illustrated.
Align the belt guide of the LH timing pulley so it faces the
rear of the engine as illustrated.
