(c) Disconnect the engine wire protector from the 2 mounting
bolts of the No. 2 timing belt cover in the sequence shown.
(d) Remove the 4 nuts, grommets, head cover and gasket.
HINT:
Arrange the grommets in the correct order, so that they can be
reinstalled into their original positions. This minimizes any pos-
sibility of oil leakage due to reuse of the grommets in different
positions.

tector from the LH side of the intake manifold.

(e) Disconnect the 3 clamps from the No. 2 timing bet cover
and generator drive belt adjusting bar.
(f) Disconnect the engine wire protector from the 2 brackets
on the front side of the intake manifold.
(g) Remove the RH scuff plate, RH cowl side trim and RH
floor carpet center cover.
(h) Disconnect the 2 ECM connectors.
(i) Disconnect the 2 connectors from the connectors on the

31. REMOVE NO. 3 TIMING BELT COVER
Remove the 3 bolts and timing belt cover.
NOTICE:
Support the timing belt, so the meshing of the crank-
shaft timing pulley and timing belt does not shift..
Be careful not to drop anything inside the timing belt
cover
Do not allow the belt to come into contact with oil, wa-
ter or dust.
32. REMOVE CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Remove the exhaust camshaft.
(1) Set the knock pin of the intake camshaft at 10 − 45°
BTDC of camshaft angle.
HINT:
The above angle allows No. 2 and No. 4 cylinder cam lobes of
the exhaust camshaft to push their valve lifters evenly.
(2) Secure the exhaust camshaft sub gear to drive gear
with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 − 20 mm (0.63 − 0.79 in.)

HINT:
When removing the camshaft, make sure that the torsional
spring force of the sub gear has been eliminated by the above
operation.
(3) Remove the 2 bolts and rear bearing cap.
(4) Uniformly loosen and remove the 6 bolts on the No.
1, No. 2 and No. 4 bearing caps, in several passes,
in the sequence shown.
NOTICE:
Do not remove the No. 3 bearing cap bolts at this stage.
(5) Remove the No. 1, No. 2 and No. 4 bearing caps.
(6) Alternately loosen and remove the 2 bolts on the
No. 3 bearing cap.
HINT:
As the 2 No. 3 bearing cap bolts are loosened, make sure
that the camshaft is lifted out straight and level.
If the camshaft is not being lifted out straight and level, re-
tighten the 2 No. 3 bearing cap bolts. Then do steps (f) to
(a) and reset the knock pin of the intake camshaft at 10
− 45° BTDC, and repeat steps (b) to (f) once again.
NOTICE:
Do not pry on or attempt to force the camshaft with a tool
or other object.
(7) Remove the No. 3 bearing cap and exhaust cam-
shaft.

(b) Remove the intake camshaft.
(1) Set the knock pin of the intake camshaft at 80 −
11 5° BTDC of camshaft angle.
HINT:
The above angle allows the No. 1 and No. 3 cylinder cam lobes
of intake camshaft to push their valve lifters evenly.
(2) Remove the 2 bolts, front bearing cap and oil seal.
(3) Uniformly loosen and remove the 6 bolts on the No.
1, No. 3 and No.4 bearing caps, in several passes,
in the sequence shown.
NOTICE:
Do not remove the No. 2 bearing cap bolts at this stage.
(4) Remove the No. 1, No. 3 and No. 4 bearing caps.
(5) Alternately loosen and remove the 2 bolts on the
No. 2 bearing cap.
HINT:
As the 2 No. 2 bearing cap bolts are loosened, make sure
that the camshaft is lifted out straight and level, after
breaking adhesion on the front bearing cap.
If the camshaft is not being lifted out straight and level, re-
tighten the 2 No. 2 bearing cap bolts. Do steps (e) to (a)
and reset the knock pin of the intake camshaft at 80 −
11 5° BTDC, and repeat steps (b) to (e) once again.
NOTICE:
Do not pry on or attempt to force the camshaft with a tool
or other object.
(6) Remove the No. 2 bearing cap and camshaft.
